Luggage Hook Element Prevents Gap During Lift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luggage items often experience a gap between their portions when loaded and lifted, leading to instability and potential damage.
Innovation Solution
A hook element is strategically placed on the second portion of the luggage, extending over the first frame element in the closed state, engaging with a recess only when the luggage is loaded and lifted, thus preventing gaps and ensuring stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the luggage is loaded and lifted by the handle, then the structural integrity should be maintained, but a gap occurs between the first and second portion
Solution Approach 1:
The hook element is designed to be dynamically engageable and disengageable based on loading conditions. When the luggage is loaded and lifted, the hook element engages with the recess to prevent gap formation. When not loaded, the hook element remains disengaged, allowing easy opening. This dynamic behavior resolves the contradiction by adapting the structural connection state to the operational state.
Solution Approach 2:
The system changes its mechanical state parameters based on loading conditions. The hook element transitions between engaged and disengaged states depending on whether the luggage is loaded and lifted. This parameter change allows the structure to maintain integrity when needed while remaining easily openable when not in use.
2Stability of the object's composition
If the hook element engages with the recess to prevent gaps, then structural integrity is maintained, but the luggage becomes difficult to open
Solution Approach 1:
The hook element is designed to be dynamically engageable and disengageable based on loading conditions. When the luggage is loaded and lifted, the hook element engages with the recess to prevent gap formation. When not loaded, the hook element remains disengaged, allowing easy opening. This dynamic behavior resolves the contradiction by adapting the structural connection state to the operational state.
Solution Approach 2:
The system changes its mechanical state parameters based on loading conditions. The hook element transitions between engaged and disengaged states depending on whether the luggage is loaded and lifted. This parameter change allows the structure to maintain integrity when needed while remaining easily openable when not in use.
3Stability of the object's composition
If the hook element is always engaged to prevent gaps, then stability is improved, but the device complexity increases
Solution Approach 1:
The hook element is designed to be dynamically engageable and disengageable based on loading conditions. When the luggage is loaded and lifted, the hook element engages with the recess to prevent gap formation. When not loaded, the hook element remains disengaged, allowing easy opening. This dynamic behavior resolves the contradiction by adapting the structural connection state to the operational state.
