Detachable Socket and Hollow Disk for Compact Torque Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices face challenges in achieving specific torque while maintaining a compact size, and they often have limited functionality due to non-detachable designs and increased manufacturing complexity.
Innovation Solution
A detachable fastening device comprising a socket, a hollow disk, and a positioning mechanism that allows for easy attachment and detachment, enabling the socket to function as both an impact socket and a common connecting socket, with the hollow disk capable of rotating elements independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a socket with a block is used to achieve specific torque through inertia force, then the securing effect is enhanced, but the device becomes non-detachable and requires large receiving space
Solution Approach 1:
The fastening device is divided into separate detachable components: a socket and a hollow disk, which can be assembled and disassembled independently. The positioning mechanism further segments the connection system into positionable elements that can be precisely located when connected while allowing easy separation when needed.
Solution Approach 2:
The hollow disk is extracted as a separate detachable component from the socket, allowing it to be removed when not needed. This resolves the contradiction by enabling the socket to function independently without the block, while still providing the option to attach the hollow disk when torque enhancement is required.
2Reliability
If a socket with a block is used to enhance securing effect, then the torque capability is improved, but the manufacturing difficulty increases
Solution Approach 1:
By separating the hollow disk from the socket into independent manufacturable components, each part can be manufactured using standard processes without the complexity of integrating a non-detachable block into the socket structure.
Solution Approach 2:
The socket is designed with universal compatibility to work both with and without the hollow disk attachment. The standardized connection interface allows the same socket to serve multiple functions depending on whether the hollow disk is attached, simplifying manufacturing by avoiding custom variants.
3Reliability
If a socket with a block is used to achieve specific torque, then the fastening capability is improved, but the device complexity increases
Solution Approach 1:
The positioning mechanism is segmented into simple positionable elements that align with corresponding features on the socket and hollow disk, creating a straightforward assembly process without complex mechanisms.
Solution Approach 2:
The positioning mechanism is designed to automatically locate and align the hollow disk with the socket during assembly, eliminating the need for complex alignment procedures or additional adjustment mechanisms.
4Reliability
If a socket with a block is used for impact socket function, then the torque delivery is improved, but the usage versatility becomes limited
Solution Approach 1:
The hollow disk can be dynamically attached or detached from the socket based on the specific application requirements. When high torque is needed, the hollow disk is attached; for other applications, it can be removed, allowing the system to adapt its functionality.
Solution Approach 2:
The socket is designed with universal compatibility to perform multiple functions: it can operate as an impact socket with the hollow disk attached for high torque applications, or as a standard socket without the attachment for other uses, maximizing versatility.

AI summary
A detachable fastening device includes a socket, a hollow disk and a positioning mechanism. The socket includes an external mounted base and at least one first depression located at the external mounted base. The hollow disk is detachably connected to the socket and includes an inner engaged wall coordinated with the external mounted base and at least one second depression located at the inner engaged wall. The positioning mechanism is received between the at least one first depression and the at least one second depression to position the socket and the hollow disk.
