Rotatable Socket Holder Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional socket storage devices experience fatigue in the elastic piece, leading to insufficient elastic force and poor restriction of sockets, causing them to easily detach from the receiving unit.
Innovation Solution
A socket storage device with a rotatable socket holder that includes an insertion portion and a locking portion, where the locking portion is biased against the engagement portion to securely hold the socket in one position and becomes movable to allow detachment in another, providing a secure locking and easy release mechanism through rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elastic piece is used to bias the projection against the socket, then the socket can be restricted, but the elastic piece becomes fatigued in long-term use resulting in insufficient elastic force and poor restriction effect
Solution Approach 1:
The patent removes the elastic piece from the system entirely and replaces it with a pure mechanical locking mechanism consisting of a blocking portion and engagement portion. This extraction eliminates the fatigue problem inherent in elastic materials while maintaining the restriction function through geometric interlocking.
Solution Approach 2:
The socket holder is designed to be rotatable between a first position (where the blocking portion engages the engagement portion to lock the socket) and a second position (where the blocking portion disengages to allow socket removal). This dynamic positioning mechanism provides reliable locking when needed and easy release when required, without relying on fatigue-prone elastic materials.
2Ease of operation
If a rotatable socket holder with locking portion is used, then secure locking and easy release are achieved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into the socket holder structure: the insertion portion receives the socket, the locking portion with blocking portion provides secure locking, and the rotatable mechanism enables both locking and release. This integration achieves ease of operation without proportionally increasing complexity, as all functions share a common structural platform.
Solution Approach 2:
The socket holder serves multiple purposes: it holds the socket in position, locks it securely through the blocking portion engagement, and enables easy release through rotation. This multi-functionality is achieved within a single integrated component rather than requiring separate mechanisms for each function.

AI summary
A socket storage device is provided, including: a base and a socket holder. The base has an assembling portion. The socket holder is disposed on the assembling portion and rotatable between a first position and a second position. The socket holder includes an insertion portion and a locking portion. The insertion portion includes an engagement portion. The locking portion includes a blocking portion being movable between a third position and a fourth position. When the socket holder is in the first position, the blocking portion is in the third position, the locking portion is biased against the engagement portion, and the engagement portion is unmovable relative to the insertion portion; when the socket holder is in the second position, the blocking portion is in the fourth position, and the engagement portion is movable relative to the insertion portion.
