Background: Student was showing creative design instincts having previously been responsible for the jewellery box design amongst others. The first design had failed, this was an attempt at an improvement to resolve the issue.
Level of Difficulty: Medium. The design premise is basic, however there has already been a considerable reworking of the original design based around problem solving. There is another area that requires considerable redesign - as viewed in the photograph above you can clearly see that the screw holes in the base of the plate are 2cm across. This clearly would not work with anything other than extremely heavy and large bolts, which would not suit the purpose of this design. Timeframe: Seven hours - this design should require further refinementm the hook itself at present is 6cm from the base, the purpose could be achieved by having something half this distance.
Size: The dimensions of the print are a depth of 5mm. 8cm wide, 12cm high. As mentioned the hook comes out 6cm from the base. The rectangle is 3.5cm by 3cm with a width of 2mm. The base plate has a depth of 5mm. Strength testing is required to see what weights of school bags could be held up and what the timeframe would be.
What we would do differently: The task needs to undergo strength test see what weight of school bag could be held and for what length of time. The holes for the two screws to attatch to the wall need to be resized and redesigned.
Next Steps for the Students: To considerably redesign the mounts for the wall and to possibly have a third screw hole at the bottom of the design. The size of these needs to be refined. There is a clear need for significant strength testing based on the size of the design, the weight of school bag that it can safely have (relative to the wall) and the length of time it will hold it for, which would be an amazing Mathematics lesson.
