Tool Box Anti-Off Structure Using Positioning Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tool box engaging members frequently fall off when opened or turned over due to abrasion and require excessive force for assembly, necessitating frequent replacement and wear on the pivoting base.
Innovation Solution
An anti-off structure featuring a positioning member connected to the pivoting connection mechanism and pivoting base, which restricts the engaging member's movement and includes a flexible roller for easy assembly and reduced wear, allowing the engaging member to be securely attached without needing a smaller opening end on the pivoting base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the opening end of the pivoting base is made smaller than the pivoting rod in diameter to retain the engaging member, then the engaging member can be retained on the pivoting base, but the pivoting base is easily abraded due to frequent replacement of the engaging member
Solution Approach 1:
A positioning member is introduced as an intermediary component between the engaging member and the pivoting base. The positioning member includes a positioning rod that fits into a positioning hole on the pivoting base, while the engaging member connects to the positioning member through a pivoting connection mechanism. This mediator prevents direct contact and abrasion between the engaging member and the pivoting base, thereby extending the service life of the pivoting base while maintaining reliable retention of the engaging member.
2Reliability
If the opening end of the pivoting base is made smaller than the pivoting rod in diameter to retain the engaging member, then the engaging member can be retained on the pivoting base, but excessive force is required to assemble the engaging member on the pivoting base
Solution Approach 1:
The positioning member serves as a mediator that facilitates easier assembly. The positioning rod with its positioning hole provides a guide and support structure, allowing the engaging member to be connected to the pivoting base through the positioning member rather than directly forcing the pivoting rod into a smaller opening end. This reduces the assembly force required while maintaining secure retention.
3Ease of manufacture
If the engaging member is frequently replaced due to abrasion, then the engaging member can be renewed, but the pivoting base suffers from wear and requires more frequent maintenance
Solution Approach 1:
The positioning member acts as a protective intermediary that absorbs the wear and tear from frequent engagement and disengagement of the engaging member. The positioning rod and positioning hole provide a stable connection point on the pivoting base that does not undergo the same abrasion as the direct connection would cause. This allows the engaging member to be frequently replaced for ease of manufacture and maintenance while the pivoting base remains protected from excessive wear.

AI summary
An anti-off structure of a tool box is provided. The tool box includes a first cover and a second cover pivoted with and correspondingly coverable on each other on a side thereof The first cover has a pivoting base, and the second cover has a clasping base. The anti-off structure includes an engaging member and a positioning member. The engaging member includes an engaging portion, and an end thereof is pivoted to the pivoting base via a pivoting connection mechanism; therefore, the engaging portion is buckleable with the clasping base when the first and second covers cover on each other. The positioning member is connected with the pivoting connection mechanism and the pivoting base to positionably restrict the pivoting connection mechanism.
