From Prelims 1, we learnt our lessons and added more slides into our powerpoint slide to eliminate the unclarity of our products, Such us a comparison chart on the current market products against our product.
Finally, we passed our Prelims 2, and proceeded to Semi-Finals.
Before Semi-Finals, we went to many different place to scout for our materials, as seen below, and triedo n many different prototype. After 2 futile tries, we finally managed to create a prototype that serves the purpose of our invention.
Below, is a video on how our prototype would work.
After searching what seems like a million shopping malls and markets...
-Lot 1
-Woodlands Civic Centre
-Causeway Point
-North Point
-Chong Bang
-Admiralty Place
-YewTee Point
-Sun Plaza
-Orchard Road
-Sembawang Shopping Centre
Finally, before we moved on to China Town, we found our AWESOME material at Teck Whye, that sure did saved us lots of trouble.
Here are the materials we used for our final prototype.
The button/things inside gives trouble to the user when spoilt.
Velcro Straps on shoes:
Strengths:
Helps children that does not know how to tie shoelace
Tightens, loosens shoes
Easy wearing/removal
Quicker than tying a shoelace
Popular for medical reasons, difficulty bending down, etc.
Weaknesses:
Velcro can stuck unwanted materials in it ( removing them is a messy task )
Does not have the "classic look" (adults hardly wear those shoes)
Loud sounds produced when unstrapping.
Velcro might lose its stickiness.
Softening of plastics.
Lace-amatic: Shoe Lace Tightener:
Strengths: Fast lace tightening, instant knotting & quick shoe removal
Problem: It might drop out if its due to the mischief of friends as they still can pull the knot. Knot might untwist if mechanism is faulty over time.
Quick Snap - Boot fasteners:
Problem:
It is rather troublesome to fasten many tighteners, as every cross between shoelaces must have a tightener.
Nathan Velocity Laces:
Problems:
There will still be some string that are not in used, even if you tuck it in like in the picture, it still might drop and you might still trip and fall.
Moreover, it does not look nice with two strings budging out.
