SA's prototype designers awarded

October 2005

A record number of prototype designs were awarded at this year's Prototype Award ceremony, hosted by the Design Institute, a division of the South African Bureau of Standards (SABS). A total of 32 prototype designs were exhibited at the Reserve Bank Conference Centre on 2 September and received awards. Several prototypes also received sponsorship support so that the designers can commercialise their designs.

New product development is an essential part of any growing economy and South Africa is no different. The SABS Design Institute is the driving force behind design promotion in the country through various award schemes, supporting innovation and entrepreneurship.
The Prototype Award scheme was established in 1997. The Design Institute South Africa and the South African Institute of Intellectual Property Law joined forces and initiated a support programme for prototypes as part of the then SABS Design Institute Awards. The Prototype scheme, aimed at assisting and encouraging new product development in South Africa, has since grown into an independent initiative and has gone from strength to strength.
The winning products serve as testimony for the ability of South Africa's people to identify and address challenges in imaginative and practical ways, as well as their skill to seek diverse opportunities to develop themselves, their communities and ultimately the country. The 2005 Prototype Award recipients are:

The game is made from scrap material, is easy to install and requires little or no maintenance.
Designer: Jeremia Gabela
Garden Res-Q
The Garden Res-Q unit utilises grey water from a home bathroom to irrigate a small to medium-sized garden. The irrigation process takes place immediately the shower is switched on or the bath is emptied, without the need to first store grey water in large tanks. The complete irrigation process is automated and as such, no intervention is required by the homeowner. Research has shown that grey water that is stored in tanks could well become pathogenic, whereas grey water utilised immediately poses no health risks to humans or animals, if used responsibly. The compact Garden Res-Q is connected directly to the outside drain pipes of an existing bath or shower where the grey water is filtered of hair and lint and a low pressure pump is activated to pump the water through a normal garden hose. Once the water has been turned off in the bathroom, the pump automatically switches off and ceases the irrigation process until the next bath or shower.

Skwid Pressure Pool Cleaner
The Skwid Pressure Pool Cleaner uses jet propulsion as a primary force to randomise the movements of the floating pool cleaner unit and to send a strong stream of water towards the collector bag, jetting debris like leaves into the bag and stirring up other debris to be collected. It consists of a dome-like top-floating unit connected to the pressure outlet of the swimming pool after a number of pool hose lengths. A short length of rigid pipe runs through it, collecting some water running through. A rotating nozzle underneath pumps the water back into the pool, causing the unit to move around. Following the top unit, downwards pointing extension pool hoses ending in four strong jets pull along a triangle-shaped collector bag of open nylon netting. The speed of the bag movement is one metre per second and cleaning is done in less than two hours. Heavy particles like stones or even dust can be collected successfully. The cleaner eliminates algae growth against walls, resulting in reduced chemical use.

Sure Blast-Long Life Fire Extinguisher
By standard, dry powder fire extinguishers have to be opened every five years to check whether the dry powder inside is still functional and an annual visual inspection is required without opening the fire extinguisher. With the Long Life Fire Extinguisher these processes can take place on a more regular basis, without the presence of a technician or having to open the cylinder. This Long Life Fire Extinguisher content is heat-treated for moisture reduction to eliminate powder agglomeration, therefore opening the fire extinguisher in the servicing process could allow for higher moisture content that can lead to erratic discharge and even malfunction. The extinguisher also has a perforated plastic sieve fitted to the end of the siphon tube, preventing any foreign matter entering through the discharge tube. Non-ferrous metal balls are placed inside the cylinder before charging. When the cylinder is shaken, these indicators make a sound, indicating that the powder has not caked up.
