Tool Hanger with Rotatable Anti-Theft Locking for Reusable Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool hangers with anti-theft features cannot be reused as they require removal of all positioning members to access tools, limiting their functionality and versatility.
Innovation Solution
A tool hanger design featuring a base with through holes, seat portions with columns and projections, and an anti-theft member with rotatable limitation portions that allow tools to be locked or unlocked without removing the anti-theft mechanism, enabling secure storage, display, and easy retrieval of tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional positioning members are used to block fitting portions, then tools are secured against theft, but all positioning members must be removed to access tools making the device non-reusable
Solution Approach 1:
The anti-theft member is divided into multiple independent limitation portions, each capable of independently locking or unlocking a specific seat. This segmentation allows individual seats to be accessed without removing the entire anti-theft mechanism, resolving the contradiction between security and reusability.
Solution Approach 2:
The limitation portions are designed to be rotatable between a locking position (blocking the projection) and a release position (allowing tool removal). This dynamic capability enables the anti-theft member to transition between secured and accessible states, maintaining both anti-theft function and reusability.
2Reliability
If positioning members are made to block fitting portions effectively, then tool security is improved, but the structure becomes more complex requiring multiple components
Solution Approach 1:
The limitation portion integrates multiple functions into a single component: it blocks the projection when in locking position, allows tool insertion when in release position, and can be rotated to transition between states. This merging reduces the number of separate components needed while maintaining effective tool positioning security.
Solution Approach 2:
Each limitation portion serves multiple purposes: securing tools in the locked position, allowing tool insertion in the released position, and providing a rotating mechanism for state transition. This multi-functionality reduces overall system complexity while maintaining security.

AI summary
A tool hanger including: a base; seat portions, disposed on the base for connection of a tool, including a projection for engagement within a positioning hole of the tool; an anti-theft member, including limitation portions and at least one connection portion which is connected between the limitation portions by a connecting section and inserted in through holes and insertion holes of the seat portions, the limitation portions being relatively rotatable; when the limitation portions are located in a release position, the projection is radially movable and the tool is axially movable; when the limitation portions are located in a locking position, the limitation portions block the projection from radially moving and the tool is axially non-movable; and the connection portion is broken and separated from the at least one connection portion as the limitation portions are rotated.
