(Excerpt) Interview with Gareth Bristow : Frank Scott: What is the main principle, idea and inspiration behind your design?. Gareth Bristow : At the core of the ROC is a recently patented mechanism that converts rotational action into multiple linear movements. During the design development of the mechanism numerous applications and potential uses including fluid and air displacement, mechanized actuators and gate valves were identified. Due to the simplicity and the anticipated low production costs of the mechanism, it was determined that it could be initially utilised to ideally create a compact and highly efficient hand pump. The internal function and the cranked means by which the pumping action is driven defined the external form of the pump, resulting in an opportunity to create a truly unique hand pump design. .Frank Scott: What has been your main focus in designing this work? Especially what did you want to achieve?. Gareth Bristow : Pumped Ltd aim was to develop the new technology for commercial uses and to initially create a pioneering range of rotary cycle pumps with a number of innovative features:- • smaller hand pumps with large pumped volumes, giving quicker inflation times • better ergonomics making tyre inflation easier and less chance of breaking valve stems • focus on design and use of high end materials making the pump a desirable object to own and use. .Frank Scott: What are your future plans for this award winning design?. Gareth Bristow : Pumped plan to refine the mechanism to increase the volume displacement potential and it is anticipated that those improvements will be used to design even smaller hand pumps with greater efficiency. In addition to the range of hand pumps, Pumped are currently developing concepts and designs to employ the mechanism in a unique range of electrically driven hand pumps, ball inflation devices, irrigation pumps and are closely looking at utilising the core pumping technologies for other leisure sectors including marine. .Frank Scott: How long did it take you to design this particular concept?. Gareth Bristow : Design of the various reiterations of the mechanism started in 2006, resulting in several patent applications between 2007 and 2012, with patents granted in Europe, the US and pending in the Far East. The base design of the ROC hand pump started in 2010 and has evolved over the last two years to incorporate the improved design of the internal mechanism into the current ROC design. .Frank Scott: Why did you design this particular concept? Was this design commissioned or did you decide to pursuit an inspiration?. Gareth Bristow : The idea for the initial mechanism derived from a few abstract thoughts relating to how a simple device, such as an actuator, could be designed to achieve a trebling its initial inert length with minimal rotational activation. A search was then undertaken to ensure that no prior art for the mechanical design existed. After a favourable patent search the early designs were then refined and improved to provide the basis of several granted patents. At an early concept stage it was concluded that the mechanism could be manipulated to produce several linear actions for a single rotation of 360 degrees and that this ability was entirely suited to pumping applications or operations requiring efficient pistons. With numerous markets and industrial sectors that would benefit from such a highly efficient and compact pump, it was decided that Pumped Ltd’s initial focus would be on a segment of the leisure market they know very well. Drawing upon their years of experience as cycling enthusiasts, Philip and Gareth were only too aware of the time and effort that is required to inflate a cycle tyre even with the best hand pumps presently on the market. Currently the top selling small pumps require at least 8 pumping actions to achieve 1 psi of pressure and the worst requiring 20 or more pumping actions. With a mountain bike tyre requiring a pressure of 50 psi, it can take considerable time and effort to inflate a tire. Preliminary modelling and analysis of the new pump demonstrated that a pump utilising the new technology could halve the current time it takes to inflate tyres. To support their initial ideas for a more efficient hand pump, there were discussi.[ End of Excerpt: Read complete interview with Gareth Bristow on Roc Rotary Compact Cycle Pump at ]
