Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the schoolbag is integrated with the tie rod baggage holder, then the burden on shoulders is reduced, but the schoolbag becomes difficult to carry
Solution Approach 1:
The invention divides the schoolbag system into two separable parts: the bag body and the bracket with tie rod. The bracket can be attached to or detached from the bag body through the zipper connection, allowing users to switch between carrying modes (shoulder carrying when detached, pulled carrying when attached) based on needs
2Ease of operation
If ropes are used to tie schoolbags to baggage holders, then the schoolbag can be pulled, but the operation is cumbersome and affects aesthetics
Solution Approach 1:
The invention merges the attachment function with the existing zipper structure of the schoolbag. The first zipper tape is integrated into the bag body while the second zipper tape is on the bracket, creating a unified connection system that serves both as a closure mechanism and an attachment mechanism, eliminating the need for separate ropes
3Reliability
If ropes are used to tie schoolbags, then the schoolbag can be secured, but it affects aesthetics
Solution Approach 1:
The attachment system is merged with the bag's existing zipper structure, using the same zipper tapes and slider that are part of the bag's normal closure system. This integration means no external ropes or visible fastening elements are needed, maintaining the bag's aesthetic appearance while ensuring secure attachment

AI summary
The invention relates to a detachable schoolbag. The detachable schoolbag comprises a bracket, a tie rod, walking wheels and a bag body, wherein a first zipper tape is arranged on the bag body, and a second zipper tape is arranged on the bracket; the detachable schoolbag further comprises a slider arranged on the first or second zipper tape. The first zipper tape can be used as a decorative tape to ensure the aesthetics of the bag body; the second zipper tape is arranged on the bracket. When in use, the first and second zipper tapes can be pulled together by the slider, so that the schoolbag can be stably placed on the bracket.
