Combined Screwdriver Storage Stability via Elastic Abutment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing combined screwdriver structures require cumbersome and inconvenient assembly procedures due to the need for additional components to stabilize the storage seat when being pulled out, which affects the overall simplicity and usability.
Innovation Solution
A combined screwdriver design featuring a handle, rod, storage assembly, abutting piece, and cap, where the rod has a positioning part with elastic pieces and a C-shaped buckle, and a stopper seat with concentric ring pieces, simplifying the structure by directly fixing the abutting piece to the rod and providing stability through elastic abutment and supporting forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components are used to stabilize the storage seat during removal, then the stability is improved, but the assembly procedure becomes cumbersome and inconvenient
Solution Approach 1:
The elastic piece is integrated directly into the rod structure, eliminating the need for separate additional components. The rod includes a positioning part with an elastic piece that directly contacts the storage seat, merging the stabilization function into the existing rod component and simplifying assembly procedures.
Solution Approach 2:
The elastic piece on the rod automatically provides stabilization to the storage seat during removal without requiring external components or complex assembly steps. The elastic deformation of the piece provides self-adjusting stability as the storage seat is pulled out.
2Adaptability or versatility
If the storage seat is pulled out for replacement, then the versatility is improved, but the stability during movement deteriorates
Solution Approach 1:
The elastic piece provides dynamic stabilization that adapts to the movement of the storage seat during removal. As the storage seat is pulled out, the elastic piece deforms and provides continuous stabilizing force, maintaining stability throughout the movement process while allowing replacement.
3Ease of manufacture
If the overall structure is simplified, then the ease of manufacture is improved, but the stability of the storage seat during removal may deteriorate
Solution Approach 1:
The stabilization function is merged into the rod structure through the integrated elastic piece, eliminating the need for separate additional components. This simplification maintains stability because the elastic piece is positioned to directly contact and stabilize the storage seat during removal.
Solution Approach 2:
The elastic piece changes its physical state through elastic deformation, transitioning from a relaxed state to a deformed state as the storage seat is pulled out. This parameter change allows the piece to provide continuous stabilizing force while maintaining structural simplicity.
