Week 7 Summary: Ma Browne As of the week 6 presentaon I had a very clear idea of my final concept. From this it became my aim to have the majority of the technicalies refined and sketched so that I could begin the final exploraon/prototyping in CAD. By having these features understood it would make my CAD process a lot simpler. This part of my project will be extremely important as it will allow me to prototype these technicalies in scale. As my project is such a large scale, physical prototyping for more then a visual form has not really been an opon for so far. Below is a very quick compilaon of some concept refinement sketchs. Not all images have been scanned as the majority are in grey ink. This doesn’t really show up using the scanner. My main aim has been to explore the slip on configuraon. Focusing on storage (jerry cans, hoses, hose tools, nozzles and foam containers). Plumbing layouts, the exact tubular framing layout, hose real motors and hose linkages. Chassis and Tank Prototyping: The next major step was to specify a final set of dimensions for the tank so that I could work on my mounng and baffle systems. To do this I had to complete an accurate model of the chassis. I used a combinaon of chassis photos I took at Mansfield DSE and blueprints found on the internet. From these images I was able to CAD the chassis and make to water tank accordingly. I was able to calculate the exact volume using Solidworks. The below images show this process.
