CAD AND TECHNICAL DRAWINGS
CAD models and technical drawings can be found here.
FOOT PEDAL EVOLUTION
The slide show to the left shows the development and changes to the foot pedal as the process went on. CAD was instrumental to inform me of spaces and positions of various components.Renders include a look at the rack and pinion system that was being considered for use and the way it would fit into the outer shell. There is also another outer shell design that takes into consideration the movement of the pedal. Unfortunately there wasn't enough time to make a prototype of this model.
OUTER COMPONENTS
These slides show all of the components that would be on the external faces of the product. This includes the outer shell, left and right pedals, base, rubber base and lid. The base is secured to the outer shell using screw (ISO 262:2 - J6). In hindsight it would've been cheaper and quicker to use a snap fit.
INNER COMPONENTS
The inner components are the components on the inside of the outer shell that you don't see but are essential in making the product function. These include; travel sensors, mini Arduino, HC-06 bluetooth module, infrared recievers, LED's, compression springs, shock plunger and a 9V battery.
To see how these components work together please see the Flow Diagram on the Other Data page.
REMOTE CONTROL
The product is controlled by a remote control. The remote was designed using the ergonomic data from the Human Factors module. The shape fits the hand easily and the buttons are bright and contrasting. They are also large enough for any users fingers or thumbs and are layed out in the sequence that the user should set up the Central Hub and Pedals.
EXPLODED VIEW
The picture to the left shows and exploded view of the pedal and all the components it consists of.
FINAL (CAD) MODEL
The renders show the final model and inner workings of the footpedal. A rack and pinion mechanism wasn't used as there was simply not enough room to justify such a small rack and pinion.
TECHNICAL DRAWINGS
The technical drawings were drawn to the BS8888 standards. They are in 3rd angle view as they were produced in the UK. Hole tolerances and depths adhere to ISO 282:2. Click the links below to see the technical drawing PDF's.
