Rotatable Tool Rack Structure for Anti-Theft Tool Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool hanging display structures, particularly those with enclosed heads, face limitations in anti-theft effectiveness and complexity, as they often rely on fragile straps or complicated elastic structures that can be easily compromised, leading to inadequate security and cumbersome assembly processes.
Innovation Solution
A simplified rotatable anti-theft tool rack design featuring an integral inserting body with a C-shaped or U-shaped limiting portion and a strap-shaped fixing element, which securely engages with the tool head, eliminating elastic structures and simplifying assembly by reducing components to three main parts, ensuring robust anti-theft performance and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening strap is used as an anti-theft device, then the tool can be secured to the rack, but the strap is easy to damage from outside and the anti-theft effect is limited
Solution Approach 1:
The patent removes the vulnerable fastening strap from the system and replaces it with an integral inserting body that directly engages with the tool head's receiving portion. This extraction eliminates the weak link (strap) while maintaining the anti-theft function through a more robust mechanical engagement system.
Solution Approach 2:
The inserting body is designed as an integral structure that combines the anti-theft function with the mounting mechanism. By merging the strap function into the rigid inserting body that directly engages the tool head, the system achieves both security and durability in a single unified component.
2Reliability
If a rotatable element with furcated elastic structure is used, then the tool can be positioned on the rack, but the hook can be pulled out or pushed back by force and the structure is complicated
Solution Approach 1:
The patent removes the complicated furcated elastic structure and rotatable elements, extracting only the essential function of tool positioning. The inserting body with its limiting portion provides positioning through a simple, direct mechanical constraint without requiring complex elastic or rotatable mechanisms.
Solution Approach 2:
Instead of using an elastic structure that pushes the tool into position, the patent uses a rigid limiting portion that physically blocks the inserting body from moving beyond a certain point. This inversion from active elastic pushing to passive rigid blocking simplifies the structure while maintaining positioning reliability.
3Object-generated harmful factors
If a sounding plate with tooth type sound generating device is arranged, then sound can be produced, but the interspace positioning causes unnecessary loose of the integral structure
Solution Approach 1:
The patent removes the sounding plate and tooth type sound generating device from the system. By extracting this acoustic component, the design eliminates the source of structural looseness and focuses solely on the mechanical anti-theft and positioning functions, resulting in a more stable integral structure.
4Ease of manufacture
If multiple components are assembled together, then the tool rack can be manufactured, but the assembly process becomes cumbersome and worker effort increases
Solution Approach 1:
The patent merges multiple separate components (inserting body, limiting portion, fixing element) into a unified integral structure. This consolidation reduces the number of discrete parts that need to be handled and assembled, thereby improving assembly efficiency and reducing worker effort while maintaining manufacturing feasibility.

AI summary
A simplified rotatable anti-theft tool rack comprises a tool rack body and an inserting body that cooperate with each other to position a tool. The tool rack body includes a limiting portion used to receive an inserting portion of the head of the tool and connected with a guiding portion. At the end of the guiding portion is disposed with a fastening portion for restricting the tool by cooperating with a fixing element. The inserting body includes a multangular engaging portion. One end of the engaging portion is disposed with a stopping flange, and the other end of the engaging portion is extended to form a neck-shaped inserting portion. At the end of the inserting portion which has inserted through the limiting portion is formed a big-diameter check portion, thus forming a simplified structure, achieving the anti-theft and rotatable effect.
