Problem
Conventional driving tools have complex structures, leading to difficult manufacturing, assembly, and high costs due to the need for separate components to retain and release tool bits.
Innovation Solution
A quick-release torque device with a main body, annular magnetic member, and push rod, where the push rod is movably inserted within a through hole containing the magnetic member, allowing for simple assembly and operation, and enabling easy removal of driven members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional driving tools use separate components to retain and release tool bits, then the tool bit can be securely retained and easily removed, but the structure becomes complex, difficult to manufacture and assemble, and costly
Solution Approach 1:
The patent combines the magnetic retention function and the push rod release function into a single integrated component structure. The magnetic member is positioned within the socket body, and the push rod interacts with both the magnetic member and the driven member, eliminating the need for separate retention and release mechanisms found in conventional tools.
Solution Approach 2:
The push rod serves multiple functions: it acts as a structural support element, a magnetic shield, and a release mechanism. By pressing the push rod, the user simultaneously controls the magnetic field to release the driven member from the socket, consolidating multiple functions into one component.
2Reliability
If conventional driving tools use separate components for tool bit retention and release, then the tool bit can be securely retained, but manufacturing, assembly, and cost increase
Solution Approach 1:
The magnetic member and push rod are integrated into a unified structure within the socket body, reducing the total number of separate components that need to be manufactured and assembled. This integration simplifies the manufacturing process while maintaining reliable tool bit retention through the magnetic field.
3Ease of operation
If conventional driving tools use complex associated structures for tool bit removal, then the tool bit can be released, but production efficiency decreases and cost increases
Solution Approach 1:
The push rod provides a dynamic control mechanism that allows the magnetic field strength to be adjusted by user action. When the push rod is pressed, it reduces the magnetic field strength to release the driven member, enabling quick and easy tool bit removal without complex multi-step mechanisms.
