Tool Hanger Pivot Groove Design for Socket Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool hangers have a complex structure that makes it inconvenient to assemble and disassemble sockets due to the lack of positioning limitations, and the production of pivot grooves is difficult and costly.
Innovation Solution
A tool hanger design featuring a main body with notches and pivot portions, including pivot grooves and pivot portions with specific diameters that allow for tilt-angle assembly and disassembly, providing rotation, position limitation, and anti-theft functionality through a simple structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional tool hanger uses pivot grooves with throat openings to clamp pivot rods, then the pivot rods are restricted within the pivot grooves to prevent disengagement, but the structure becomes complex and difficult to mold
Solution Approach 1:
The patent removes the complex throat opening structure from the pivot groove and extracts the clamping function to a separate positioning column. The pivot groove becomes a simple容纳 structure while the positioning column with its protrusion provides the restriction function, separating the clamping function from the groove structure itself.
Solution Approach 2:
The positioning column acts as an intermediary element between the pivot rod and the pivot groove. Instead of the groove directly clamping the rod through a complex throat opening, the positioning column with its protrusion mediates the restriction, making the overall structure simpler and easier to mold.
2Device complexity
If a conventional tool hanger allows seat bases to rotate relative to the main body without positioning limitation, then the structure is simple, but the seat bases can easily disengage from the main body
Solution Approach 1:
The pivot portion of the seat base automatically engages with the positioning column's protrusion during assembly. The structure itself provides the positioning limitation function through its geometric design, where the protrusion and corresponding groove create automatic mechanical interlocking without requiring additional complex mechanisms.
3Reliability
If a conventional tool hanger uses a cover to prevent seat bases from disengaging, then the disengagement prevention is achieved, but the overall structure becomes complex
Solution Approach 1:
The patent extracts the disengagement prevention function from the cover and relocates it to the positioning column structure. The cover becomes a simple protective element while the positioning column with its protrusion provides the active restriction function, eliminating the need for a complex cover mechanism.
