Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional torque wrench with a single drive head is used, then the structure is simple, but the functionality and adaptability are limited
Solution Approach 1:
The patent combines two drive heads into a single torque wrench body, allowing the tool to perform multiple torque applications simultaneously or independently. The two drive heads are integrated into one handle structure with a shared adjustment mechanism, enabling the wrench to function as both a single-drive and dual-drive tool without requiring separate instruments.
Solution Approach 2:
The torque wrench is designed to perform multiple functions through its dual drive heads, which can be independently adjusted to different torque values. This allows the single tool to replace multiple torque wrenches with different torque settings, providing universal applicability across various fastening requirements while maintaining a relatively compact design.
2Adaptability or versatility
If a torque wrench with double drive heads is provided, then the adaptability and functionality are improved, but the device complexity increases
Solution Approach 1:
The patent merges two torque adjustment mechanisms into a single integrated system. The adjustment member simultaneously controls both drive heads through a unified mechanism, allowing torque values to be set for both drives through one coordinated adjustment process rather than requiring completely separate adjustment systems for each drive head.
Solution Approach 2:
The adjustment mechanism is designed to be dynamically configurable, allowing the user to independently set different torque values for each drive head or to link them for simultaneous adjustment. The mechanism can adapt its operation mode based on whether the user needs identical or different torque settings on each drive, providing flexibility without increasing structural complexity.
3Productivity
If the adjustment member drives both slide blocks simultaneously, then the torque values can be set at the same time, but the ease of operation may be reduced
Solution Approach 1:
The adjustment member is designed with dynamic control capabilities, allowing the user to choose between simultaneous adjustment mode (for quick setup when identical torque is needed) and independent adjustment mode (for precise control when different torques are required). This dynamic operability maintains ease of use while enabling efficient bulk setting when appropriate.
Solution Approach 2:
The adjustment mechanism allows changes in operational parameters based on user needs. When the same torque value is required for both drive heads, the system enables simultaneous parameter setting for efficiency. When different torque values are needed, the system allows independent parameter adjustment, maintaining operational ease through adaptive control modes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise and safe operation by providing two drive heads with adjustable torque settings, enhancing user control and preventing over-tightening by indicating when the set torque value is reached.
Implementation Method 1
The two elastic members apply elastic force to the two drive heads. The elastic force of the spring 16 is exactly the set torque value of the torque wrench.
Implementation Method 2
A spring 16, a slide block 17 and a rotary button 18 are sequentially disposed in the outer handle 11 behind the rod body 12. When rotating the adjustment grip 19, the slide block 17 is driven to axially move within the outer handle 11. The slide block 17 can be positioned in different positions to compress the spring 16 to different extents.

AI summary
A torque wrench with double drive ends includes a handle having at least two hollow tubular bodies coaxially connected with each other, two drive heads respectively disposed at two ends of the handle, and a double torque adjustment mechanism including at least one adjustment member, two slide blocks and two elastic members. The two slide blocks are movable within the two tubular bodies. The adjustment member is positioned between the two slide blocks for driving the two slide blocks. The two elastic members are respectively positioned between the two slide blocks and the tubular bodies. By means of the adjustment member, the elastic force applied by the elastic members to the drive heads the can be adjusted to set the torque values thereof.
