Transcript: Material & Manufacturing Process New Consideration & Designs Current Products As its name, the device holds three brush heads on both top and bottom. The brushes go along the mouth piece shape. This idea allow users to freely use hands when brushing their teeth.

Chair 53% Diabled Men 20% Disabled Women 65% Non-Disabled Men 30% Non-Disabled Women In order to start off the project, design techniques were used to generate ideas. Mindmapping was used to organize the brainstorming process, keyword listings to create spontaneous ideas. Usage of the design techniques were very effective for generating ideas were the main problem of the project as mentioned before. Despite all the designing and considerations, the device was over complicated and too costly at the end. The product possibly could be dispensed in high income countries, However with new data and considerations on the left, there was a need to design a much simpler and cost effective "Walking Wheelchair" for lower income countries. The aim is not only to aid walking but to allow injured/disabled people to keep their working spots since the device takes less space then a wheelchair. designbuzz.com 12" HDPE Rims The aluminium body framework would be produced from cold chamber die casting. The HDPE chair and the wheel rims would be produced through injection moulding. The foam, bearings, tires, and caster wheel will be bought separately and assembled. -who.int Design Techniques Picked Up Ideas User Research Market Research iPDS & FMES & Visual iPDS Parts Design Sketches New Consideration & Design Materials Final Design Parts Design & Integration designbuzz.com With the research done, next was the actual product designing. In order to aid the disabled user to the fullest, a lot of parts and devices were added to the design. iPDS and the visual iPDS was used to lay down all the requirements and possible requirements for the product. FMEA was then under taken to list out the safety and maintenance of the device.

Producing innovative ideas within the medical and grooming industry was a hard working task, for in depth knowledge of the two subjects are necessary. To attack the task, creative design techniques were used to generate numerous ideas which was then taken further into consideration. Current walking aids used in reality is very outdated. Products we see normally in the UK are still the same design as the 1970's, and there has not been many innovative products out in the market. Handle Grip & Seat Lower-income countries have a higher prevalence of disability than higher-income countries. Disability is more common among women, older people and children and adults who are poor Must take minimum space for storage Leg can be pulled out when patient calls for pain on legs and is necessaray for legs to rest Small storage beside arm rest Need for it to be water resistance Safety when walking on ice Easy to pass curbs and bumpy or off road Posture Supporter Aid the walking of a disabled person Wheelchairs, Crutches, Walking Assisst Devices People with difficulty walking Motor on the hinges pushing legs Motor on wheels Not too much power but enough to assist Placement of force that aids leg movement equally Air ventilation & Pressure point considered Material- mesh, foam Air ventilation & Pressure point considered On seating cushion Usage of durable materialthat is non-brittle with high fatigue fracture count Tires -quick release Adjustable height of seat Adjustable leg length Adjustable back rest 12" Pneumatic Tires One wheel is placed in front of the other, with a movable piece connecting the two, allowing one tire to go up the crub and the other on following. Medical/Grooming Device The "Walking Wheelchair" features the user to sit down on the adjustable chair, high enough for their feet to reach the ground. One user can comfortably sit on the chair using the back rest, or the other can sit upright and grab on to the handles (if necessary) to walk. The caster wheel in the front allows the "Walking Wheelchair" to be directed towards any direction the user feel to walk towards, and the two detachable pneumatic wheels on the back with the suspension system allows any user to go over anything from street curbs to big rocks or sticks on the ground. Breaks are also applied for emergencies and going downhills. Introduction How to turn around? With assist leg? Stable Leg Leg (knee)
