‘SPIKEY’ Surge Protection Plug

Redditch Plastic Products 1999

Work on the surge protection plug began in 1998

as a new project plan. The company already produced a surge plug but Spikey combined

innovative new manufacturing solutions and a

more aesthetic design.

Spikey was drawn on Solidworks ’99 and was the

first ‘live’ project that I worked on. Design

included packaging, leaflet, brass and

poly-carbonate components.

‘MycoLAB’ Project for HRI Coventry University 1998-99

MycoLAB was the follow up to a design

for a mushroom testing machine, developed by the School of Engineering.

This packaged solution was part of a

presentation to the horticultural research

institute, and was a partially functioning

prototype complete with ‘running lights’

and mechanism.

Decorative Toggle Switch Redditch Plastic Products 1999

The project plan was based on an existing

switch mechanism. The toggle mechanism and

plates for 1,2 and 4 gang versions

were designed.

Now in production, emphasis was placed

on creating an attractive competitor to other

leading brands. On sale in B&Q warehouse.

Children’s Weighing Scales Project 1998

This bucket type weighing scales was a

coursework submitment “Weigh It Up” for a 2nd year university project.

Shown is the actual prototype which was vacuum

formed in red, yellow and blue plastic. It was used in trials by children and I am looking to have it put

into production.

The balance uses no metal or small parts, the

mechanism comes solely from the shape.

“SPACE JAMMERS” Toy 2000

I produced a toy based on universal accessibility; for use by children of any ability or intergenerational

play. The prototype shown below in the photographs were fully-functioning.

(left) The product was also extensively tested

at schools. The work was carried out in conjunction with help from the school of

psychology.

A single 'Space-Jammed'

prototype.

“ECB” Environmental Concept Bus 2000-01 The vehicle below was presented to West Midlands Transport and submitted as a showcase featuring a

number of design innovations. An 'electro-mechanical-battery' to store, wall mounted seating to aid in the cleaning of the interior of the vehicle, smart seating, and an innovative articulated central steering

mechanism.. The transport operator expressed interest in many of the ideas put forwards, and I hope to

have provided good ideas to expand and improve public transport.

Fusion Works 2004-06

SolidWorks Reseller and Consultancy.

Danum Technology College, Doncaster 2006-Present As specialist teacher of Engineering, these are projects that I designed for pupils. Planning and preparing

excit ing projects and work where children learn from creat ing, and designed to inspire them to learn.

workshop skills, pupils are encouraged to assess and improve designs with educational worksheets and

interactive online guidance.

(below) as Unit 2, the pupils must build a robot car to perform tasks. The school has bought

components for 30 vehicles, which are to my own design. The project teaches microcontrollers and

production planning using gantt charts and

operates like a manufacturing company.
