  7. Average weight of primary school student’s bag After doing our very own survey on 15 primary students, here’s the average weight of a primary school student’s bag and percentage… • Highest weight: 6.3kg • Average weight: 4.85kg • Highest percentage: 21% • Average percentage: 15.18% This shows that the problem of overloaded bags is very serious…

  8. Consequences of carrying heavy bags • “Heavy bags put kids off balance, causing them to have a posture that increases the likelihood of lower back pain” ---Dr. Wayne Yankus, American Academy of pediatrics • Study conducted at Auburn University reported that carrying heavy bags may threaten the developing spine • Of the children who participated in the study, over half suffered from muscle soreness and back pain, while others suffered from numbness and shoulder pain • Source:http://www.ehow.com/about_5044276_back-caused-heavy-book-bags.html#ixzz1IvxqNR1Q

  11. Timeline

  12. Survey data (9th April)Sample size: 20 students • Do you feel that your bag is heavy, causing discomfort and giving you shoulder and back aches?

  13. Survey data (9th April)Sample size: 20 students • Would you buy this product if it was sold? • How would you rate this invention? (excellent/good/bad/very bad)

  14. Survey data (9th April)Sample size: 20 students • What price do you think is reasonable for this bag?

  15. Comments/suggestions • I’ll be able to know if my bag is too heavy so I won’t get shoulder aches! That’s cool! • I can prevent shoulder and back aches so my spine will not get injured. However, users might just ignore the weight even if it’s too heavy. There should be an alarm or buzzer. • It is a good idea, pretty practical, and cannot be found anywhere in the markets.

  16. Design of Superbag • Original: Just a platform connected to the weighing scale • After modifications: platform connected to weighing scale with piece of material in front to prevent books from falling out of platform. Base of platform is also tilted inwards so the books will not fall forward, hence making the reading more accurate.

  17. Final design Weighing scale pocket platform Base tilted inwards at about 60 degrees

  19. Bad Points of Superbag  • You have to lift the bag up first then only can it weigh itself • It doesn’t have an alarm if it’s too heavy for you • The weighing scale might take a while to switch on sometimes

  20. Some Advice • Carry haversacks with straps on both shoulders – spread out stress • Do not put unnecessary things in your bag – reduce weight • Do not squeeze bulky things into your bag – bag won’t be bulky, reduce weight
