Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional powered ratcheting torque wrench uses a single grip-driven transducer assembly, then the structure is simple, but only a single detecting function is provided
Solution Approach 1:
The patent combines two separate detecting functions (bending strain detection and torque deformation detection) into a single integrated torque structure. The first and second strain gauges are mounted on the same first body and receive the same drive force, allowing dual functionality without requiring separate tools or complex series assembly of multiple complete assemblies.
Solution Approach 2:
The torque structure is designed to perform multiple detecting functions simultaneously - it can detect both bending strain (when the driving portion is perpendicular to the drive member) and torque deformation (when the driving portion is in line with the drive member). This multi-functionality is achieved within a single unified structure rather than requiring separate specialized tools.
2Ease of manufacture
If the transducer assembly is assembled in series with the drive assembly and main housing, then the assembly process is straightforward, but the assembly structure becomes poor and time-consuming
Solution Approach 1:
The patent merges the transducer assembly components (first body with strain gauges) and the drive assembly components into a single integrated structure. The first body serves as both the mounting structure for strain gauges and the mechanical element subjected to drive forces, eliminating the need for separate series assembly steps between transducer and drive assemblies.
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
Enhances the utility and versatility of the torque wrench by enabling detection of both bending strain and torque deformation without the need for multiple tools, simplifying operation and assembly.
Implementation Method 1
The first strain gauge is received in the first receiving groove to detect a bending strain in response to a bending force applied to the first body
Implementation Method 2
The second strain gauge is received in the first receiving groove to detect a torque deformation amount of the first body
