Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shoulder belt is attached to the suitcase body, then the suitcase can be used as a backpack, but the shoulder belt sags and becomes dirty or is run over by wheels when wheeled
Solution Approach 1:
The shoulder belt storage function is segmented from the main suitcase body by providing a dedicated storage pocket on the back surface. This separates the belt's functional attachment points from its storage location, allowing the belt to be neatly stored away when not in use, preventing sagging and contamination while maintaining backpack functionality when needed.
2Object-affected harmful factors
If the shoulder belt is removed and stored in a pocket, then the belt does not sag or become dirty, but the process of attaching and detaching is troublesome and time-consuming
Solution Approach 1:
The shoulder belt is pre-attached to the suitcase body at fixed positions before use. The belt is permanently secured to the suitcase structure with attachment points positioned to allow easy access and quick attachment/detachment without requiring complex fastening or removal procedures, thus saving time while preventing contamination when stored properly.
