Prototype made from 3D printing is very appropriate. It demonstrated working functionality and some reliability.
Design considerations like minimal use of material just to support the needed points of a cup are good.
During development, Colin generated in total five non-repeated ideas, ranging from static, dynamic, friction, suction, magnetic, etc. I complimented Colin for his strength in idea generations.
The project can be improved by conceptualizing foldability features, illustrate ease of collapsing and setting up, to save space when not in use.
Elderly or the less-abled people, especially those with hand issues may also have special utensils, including a cup that does not topple easily. There may be exhibits in the SGE Tech Able showroom that aims to tackle similar issues.
With more people going for food deliveries, food in liquid form takes special delivery packaging to minimize spillage during transportation (often motor-bikes or bicycles). Pupils may extend solutions to attend to needs in these areas. If proven successful, more food will go into the take-away list and translate to real business for vendors.
