Wk 5 - Product Lifecycle assessment+Product disassembly
















Interesting how this product uses various type of plastics. It is surprising to find not all are made of one kind of plastics. I think many designs and products would be more sustainable when they use one to two different materials. But for this product it uses steel for aesthetic and fastening joints, ABS for stronger robust build, PC for wall thickness and aesthetic, PE for functioning handheld parts, SAN for transparent quality.

It puts me to think of using materials and fastening joints more efficiently such as reduce the amount of screw and bolts fastenings, e.g. the efficient design would be to use mechanical snap fits and slots.

Wk4, Prefinal + Week 4 consultation reflection, no.4

First question to Cormack, was about the wall thickness of the container, and the wall thickness should ideally be uniform. Second question, was PET material suitable for this design, and PET would be crushed (deform) under mechanical stress, e.g. PET soft drink bottles can be crushed. Third question, if the squeeze design possible, and the design may need a spring mechanism or something that will assist the container retain original form after the squeeze pressure.

Tutor - There is need of little tweek in the ergonomics for the container to fit comfortably for the hand. The base cap may need to be wider/bigger surface to able to stand upright on the enclosure. Poster can be improved by showing context of use, such as illustrated hands. Show more sectional drawings on CAD.

Focus Group - Poster needs context, such an image of a toast with honey dispensed from the container. 
Graphics and embossed features on the container can improve the visual and aesthetic of the product, e.g. have hexagon-geometry to represent honey-comb. The title/name of the product can be changed and be more related to the squeezing function.

Week 3 consultation reflection, no.2

Tutor Tom - Test the squeeze function by generating a plastic model. There is sometimes the honey would not dispense and the build up pressure in the silicone valve would blow a big blob of honey. Search up what material and process for the design. Design the enclosure, and test the design with appropriate materials. Find out what is wrong with existing packaging for honey.

Peer 1, Christine - There are laminated material used in tube packaging that eases the dispense of the last-few contents, which would have been difficult in other plastic packaging.

Peer 2, Clement - The grip comfort is alright on the mock-up model, but it needs more ergonomic design for the hand palm and the thumb. Adjusting the edges and the side curves of the bottle would help create more comfort and secure grip for the user.

Other tutor, Mar to another student - Conduct experiments of upside down containers that are in the market, and investigate this feature with the proposed food product. Understand the nature, e.g. viscosity of the oil, and observe the result. Consider the use of the packaging design, such as hygiene, user interaction, packaging seal, graphics and labelling.

Reflection, This week, I plan to generate a model of the bottle design with vacuum form PETG sheets, to try the squeeze action with actual honey content. I hope to have the result and make it a convincing evidence of the primary research. Also to do testing of the enclosure fitting in relation with the squeeze plastic. Research into what materials and process to is appropriated for the design. Discover a way to get the last contents without the objective of minimal frustration and exclude the use of tool. Test the valve, and consider the pressured honey-blob dispense. Begin CAD drawing on solidworks and presentation posters.

Further 2D Sketches and mock-up developments









In the drawings, the design needs to lose some surface areas which were unnecessary, and would add the extra material costs.
Further edges needed angle and smoother fillets for more comfortable grip. Also to add some circumference surface to add on the flat features shown on the white foam core.
Another shape container was explored - the triangular container.

Empathy test

 Empathy test of an arthritis user with the honey packaging, by using cloth padding to simulate the swelling and inflexible movement of the hand, fingers and thumb. Actions perfomed were gripping and squeezing. Two different type of packaging used are, PET squeeze bottle and Plastic laminated-layered squeeze-tube.
With the thick padding the grip on the container was an unnatural feel to the hand ergonomic, and made it an uncomfortable grip-hold. I find that I need to use more grip strength, because I want to bend more of the fingers and I was trying to stretch my fingers for better grip, but I could not do that because of the obstructive padding.
 Without the padding, the design of the container is very comfortable to grip by the hand. Visually by the photos here, I can see the difference of the grip diameter of the un-padded hand and the padded one. And also the placement of the fingers were in different position.

 With this tube packaging and testing with the unpadded hand and without, gave the same result as the first test. But this type of packaging is more comfortable to grip with the padded hand compared to the previous PET container.

 The testing of the flip opening of the lid is easier on the tube (left), with very minimal strength need to be used. A comment made by my class peer said the palm of the hand can even open the flip cap.
The flip cap on the PET container (right) requires more strength to open and the palm of the hand cannot open the cap, as it did with the tube.

The PET plastic is a tougher material and harder to squeeze or press to dispense the content. My experience with this product, it was easy to use and dispense the honey when the container is full. The action to get the honey is still do-able when it is half-filled. But it was only really hard to get near-empty honey that was left in the container.

The laminate-tube have solved this problem. However the geometry of this tube is more cylindrical and the smooth surface may prove more risk of slip from the hand grip of an arthritis.

My reading from the Australian Packaging Covenant, reported packaging design should avoid cylindrical design, and instead to adopt elliptical and have corners to offer better grip and reduce the risk of slipping/dropping the bottle/container.

What I like about these packaging design is the upside down standing, to make easier dispensing of the high viscosity honey.

I find that both products have packaging sealing problem and I think they would not benefit the arthritis.
They used the aluminium foil with very small surface edge for fingers to grip, and the external seal has a large surface area, which requires a user to a tool to cut away the excess, or the user have to peel the whole seal off, that contains all the labelling and texts, and this would require unnecessary actions and frustrations.

The above image can show that the PET plastic (right) are some ripping on the labels because I have used a pair of scissors to cut away the top seal from the rest.

VIDEO Reflection :- LCA lifecycle analysis

1. Real sustainable solution is where designs approach the whole system of the product, and address the (full) life cycle of the product. The whole system and lifecycle, encompasses the beginning process of extracting raw material, using of these materials and manufacturing the good, distribution by transport, retail and purchase, usage of the product by the consumer, disposal and product reaching end of life.
2. Sustainable designs should begin with identifying the big issue with the biggest impact on the environment within that whole system and lifecycle. Probably need of extensive research to identify this problem, may require finding through other professionals, scientists, engineers, marketers, and consumers.
3. Tackling the largest impacting issue in the system with strategies, and addressing the entire lifecycle with improvements. So by doing that, the solution can be labelled as innovation design. Designers repeating the process of improvement using the two principles of the whole systems and the lifecycle thinking, can result in innovative solution, to help the world.
Conclusion
Many designers look to improve with a solution of reducing material and cost for sustainable design, or, creating higher performance improvement for better efficiency.  But these solutions may just be minimal improvement and does not actually address the problem at hand. The video does bring to light and ring the bells for what is the most likely better way of designing a sustainable solution, and it’s to look at the whole system:- the extraction, manufacturing, distribution, consumption, disposing, recycling, and the entire lifecycle of the product. Because each level of the product lifecycle have impact on the environment, e.g. land deterioration in extraction, carbon emission in manufacturing, air pollution in distribution, litter in consumption and disposal, water and high energy use in recycling. Viewing this video, I feel I have finally understood what is a truly sustainable and innovative design meant. As a design student I think the lesson from the video is noteworthy – it’s the whole system and the lifecycle that requires the effort of designs. Not the product itself.

(2) Video: Autodesk: Improving product lifetime

1. Better design is recyclable materials, disassemble, durable and longer lifespan, good end of life –e.g. biodegradable effortlessly and harmlessly, or turn product to be re-useable at after-life.
2. Repair and upgradeable are recommended. Keywords: “Extending useful life”. Designers and companies to adopt take-back-programs.
3. The concept of sustainable reduces the use of virgin materials and reduce waste at landfills, via recycling, reusing, and repair;- and the hope to stop extracting resources and zero contents to the landfill.
Conclusion
The video is a great learning about the scarcity of our earth and it serves a well reminder to designers, manufacturers, business and consumers. The design process and considerations have become increasingly relevant, as today’s society is very conscious of our own actions and inactions, on what we are doing to our resources and the environment. It is a nice thing to think if a concept can be achieved when a product can be manufactured beautifully again, without the need of anymore resources and there could be no more landfills.

(3)Video: Autodesk: Lightweighting

1. Lightweight can be relevant for sustainability and innovation. Due to use of less material in manufacturing, and obviously this would be good for sustaining resources, less negative impact from production to disposal, and lower costs.
2. There are strategies to reduce material usage, the maximising the strength of the material/product, such creating ribs in plastics, trusses and hollow parts in steel, and other more solutions to improve the geometry of the product.
3. Lightweight principle should not be used if it becomes liable to users, and/or prove harmful.
Conclusion
Certainly making lightweight solution for a product is beneficial to also transportation of these goods, and will benefit consumers, especially to users who have disability conditions, e.g. arthritis and muscle/nerve tremors. It may be beneficial to consumers because of lower purchase cost, increase portability for handheld products and improve performance and efficiency for heavy duty and capital goods. Lightweight is a definite good sustainable strategy and should be noted by designers.

(4)Video: Autodesk: Green materials selection

1. Consider all materials and select the most greener one. The greener material will usually be the most abundant –e.g. bamboo, and requires less energy to manufacture.
2. Every material put to production, will have embodied energy and it is ideal to select material that have lower embodied energy, which mean less use of water, electrical power and other resources.
3. Sustainable design means also to consider the origin of the material and its ecological impact; - it is encouraged to get materials from certified suppliers, because they have the best program for sustainable resources and they conform to regulations.
Conclusion
It is always best to find an alternate material that could provide the wanted performance, and also become the better sustainable outcome for the manufactured goods. Greener materials, such as bamboo, corn-starch, natural rubber, and even the recycled aluminium is very efficient, as the embodied energy of a recycled aluminium is 90% less than production of virgin Aluminium metal. So using recycled materials should always be an option for all designers.

(5)Video: Autodesk: Energy efficient design

1. Understanding the use of energy, the origin and the loss. Sustainable designs to use energy efficiently, to reduce the loss of energy, e.g. with friction – use smooth material, wheels, lubricant.
2. Loss of energy in heat, friction and fluid flow (drag)(resistance). Sustainable designs can require the knowledge of physics and mechanics.
3. Sustainable design using efficient energy, saves – time, cost, material, and the product will reap higher performance.
Conclusion
Many commercial products in the market and the energy use to produce them are probably not well considered by designers and businesses. The ones that could be thought to have design consideration for energy saving are television, refrigerators, microwave, washing machine, toilet, some automotive vehicles. So only a few products manufactured adopt energy saving programs. It seems very complex to understand the principles of energy, even for a student like me. It seems good understanding or physics, research and maybe collaboration with engineers are important when designing products for complex goods, such as household appliances. Though one example, where incineration of rubbish wastes in plants can produce energy which in turn converts to electricity to provide power to mechanics, however it is not a sustainable process. Perhaps in the future energy that are lost, e.g heat, friction and fluid flow, those energy could be redirected to be use to make energy, and today concepts are being generated to see to these.

(6)Video: Greenfly

1. Transport and distribution is a large player in negative impact. And will demand high usage of energy if there is long distance of travel.
2. Water usage in production is high compared transport and use of the product.
3. High wastes results from manufacturing and transport. Recycling can reduce solid waste.
Conclusion

Using the analysis of Greenfly on my Project One Accessible packaging design, of a Honey container, the data has taught me that there is a need of solution for the high energy use by transport. And I don’t think there are any solutions out there to address about transport directly. There is a large waste from transport and manufacturing. If to make a more sustainable design for my project I will not focus on transport mode, and manufacturing material and process, and come with a more efficient way, to reduce energy, solid waste, and water usage.

Week 2 consultation reflection, no.1

Tutor Tom :- consider to reduce the splash of the condiment, when dispensed from the container. Prevent that splash so there will be no cause of mess, e.g. tomato sauce containers are capable of that. And it is best the packaging is free of frustration for an arthritis person - to clean, so investigate appropriate enclosure design for that cause. Research on which plastic materials to achieve your solution on collapsible and retaining form container.

Peer 1, Richard Trajcevski - is agreeable with concept-1-honey packaging. Richard say, "the squeezable/collapsible soft plastic of the honey container is a design that can benefit other sauce and condiment packaging"

- because the design may be able to minimise fatigue level and reduce the need for more hand strength to dispense.

Peer 2, Felicia Levina - consider the honey can have high level of viscosity and are sticky, so dispensing a honey from the container can be hard. Especially trying to get the honey that are stuck to the bottom of the container. Concept 3-insect-spray, existing product have triggers that can require a lot of finger strength to press. "I need my two hands to use the spray, because my finger does not have the strength to press the trigger"

Other tutor Scott - the good packaging is of course suppose to be accessible, easy to open for the intended user. And is also important the packaging can be closed after use. Make sure the design address your one-main issue so your project will have a very strong solution to solve your researched issue.

Reflection - I've decided to work on concept-1, the honey container, which is also a suggestion from my tutor and peers. For this week I will look into ways to prevent the splash and drip from the container, research into what plastic materials the could be suitable for the design. Thorough research on other types of enclosures of existing products. And think about the characteristics of the honey, especially its stickiness and high viscosity that can proved to be difficult to dispense from the container. I will also begin blu foam modelling to discover the appropriate size of the container, and consider the ergonomically hand length and size, for the hold of the container.

Research - Existing Honey Packaging

Existing honey packaging, such as the traditional heavy-block-glass jar and tightly sealed screw cap, are a difficult for disabled-users who have arthritis. Squeezable hard-plastic packaging type proved to very hard to dispense honey from the container, even non-disabled users find it uncomfortable for having a lot of hand strength to dispense the content.
