Socket Holder Post with Axially Offset Convexities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional socket storage devices experience elastic fatigue of their retaining mechanisms, leading to a gradual deterioration of the elastic force, causing sockets to disengage easily from the storage device.
Innovation Solution
A socket holder design featuring a post with multiple convexities that engage with the socket's positioning holes and inner walls, providing stable multi-point engagement and preventing overtightening, ensuring reliable socket retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shrapnel with elastic force is used to retain the socket, then the socket can be positioned and retained effectively, but the elastic force deteriorates over time due to elastic fatigue, causing the socket to disengage easily
Solution Approach 1:
The invention extracts and eliminates the elastic shrapnel component from the system. Instead of using an elastic mechanism that degrades over time, the patent employs a rigid post with convexities that provide retention through geometric engagement with the socket's positioning holes and inner wall, removing the source of elastic fatigue entirely
Solution Approach 2:
The invention replaces the elastic mechanical system (shrapnel relying on elastic force) with a rigid mechanical system (post with convexities relying on geometric constraint). The retention mechanism transitions from force-based elastic engagement to geometry-based rigid engagement, eliminating the durability issue associated with elastic material fatigue
2Stability of the object's composition
If multiple convexities are used to engage the socket, then the engagement stability is improved, but the device complexity increases
Solution Approach 1:
The invention segments the retention function into two distinct convexities on the post: a first convexity that engages with the socket's positioning hole for primary retention, and a second convexity that abuts against the inner wall for secondary stabilization. This segmentation divides the complex retention task into simpler, specialized sub-functions, achieving stable multi-point engagement while maintaining structural simplicity
Solution Approach 2:
The post structure serves multiple functions simultaneously: it provides positioning through the first convexity, stabilization through the second convexity, and guides the socket during insertion. The single post component with two convexities performs what would otherwise require multiple separate components, reducing overall device complexity while achieving stable engagement
