Socket Detent Elastic Biasing Mandrel Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket apparatuses for pneumatic or electrical tools lack a secure connection mechanism, as the detent on the mandrel is inadequate for maintaining a firm attachment.
Innovation Solution
A socket apparatus incorporating a detent and an elastic element, where the detent is inserted into an aperture, and the elastic element biases the detent to maintain secure engagement with the mandrel, ensuring a firm connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detent is provided on the mandrel and inserted in the vent to keep the socket on the mandrel, then the socket can be connected to the tool, but the connection is inadequate and not firm enough
Solution Approach 1:
The connection mechanism is divided into multiple independent detents (at least two detents) instead of a single detent. Each detent can engage with the mandrel separately, distributing the connection load and providing redundant engagement points, thereby improving overall connection reliability without significantly increasing structural complexity
Solution Approach 2:
The detents are designed to be movable relative to the socket body, allowing them to flex and engage with the mandrel dynamically. This movement capability enables the detents to adapt to manufacturing tolerances and maintain firm connection under varying operational conditions, enhancing connection reliability
2Ease of manufacture
If the socket structure is simplified for ease of manufacture, then manufacturing cost is reduced, but the connection firmness becomes inadequate
Solution Approach 1:
The detents are designed to be elastic elements that automatically engage with the mandrel when the socket is assembled. The elastic deformation of the detents provides self-centering and self-adjusting functionality, eliminating the need for complex adjustment mechanisms or precise manual alignment during assembly, thus maintaining ease of manufacture while achieving firm connection
Solution Approach 2:
The detents utilize elastic deformation (change in physical state) to achieve engagement. By selecting appropriate elastic materials and designing the detent geometry to operate within elastic limits, the system achieves reliable connection through material property changes rather than complex mechanical structures, balancing manufacturing ease with connection firmness

AI summary
A socket apparatus includes a socket, at least one detent and an elastic element. The socket includes a bit-receiving recess in an end, a mandrel-receiving recess in an opposite end, at least one vent in communication with the mandrel-receiving recess and at least one aperture in communication with the mandrel-receiving recess. The detent is inserted in the aperture so that the detent includes a portion disposed in the mandrel-receiving recess. The elastic element is used to bias and keep the detent in the aperture.
