Solution Overview
Problem
Conventional mechanical torque wrenches have a fixed internal structure and lack innovative adjustment mechanisms, limiting their development and precision in applying torque to threaded components.
Innovation Solution
A torque wrench with a novel elastic member configuration, featuring a tubular body, working head, click mechanism, and adjustment mechanism, where the elastic member has a unique shape (e.g., M-shaped, N-shaped, S-shaped, U-shaped) with arched bent sections and plane or non-plane connection sections, allowing for stable torque adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional coiled spring is used as the elastic member, then the torque wrench can provide elastic force for torque adjustment, but the internal structure becomes fixed and lacks innovation
Solution Approach 1:
The elastic member transitions from a static coiled spring to a dynamic plate-shaped structure with multiple bent sections that can be adjusted between extended and compressed states. This dynamic configuration allows the torque wrench to adapt to different torque requirements while maintaining a compact form factor, resolving the contradiction between innovation capability and structural simplicity.
Solution Approach 2:
The plate-shaped elastic member features adjustable bent sections that can change the stiffness and elastic force characteristics. By modifying the degree of bending and the number of active sections, the torque wrench achieves variable torque adjustment without complex internal mechanisms, balancing adaptability with structural simplicity.
2Measurement precision
If the elastic member is compressed to adjust torque value, then precise torque control is achieved, but the structure requires stable and reliable configuration
Solution Approach 1:
The elastic member is divided into multiple bent sections that can independently deform and distribute stress. This segmentation allows precise torque control through selective engagement of different sections while maintaining overall structural integrity and reliability during compression and extension cycles.
Solution Approach 2:
The plate-shaped elastic member incorporates pre-bent sections that act as cushioning elements, gradually absorbing and distributing compressive forces. This prior cushioning design prevents sudden structural failures and ensures reliable operation during torque adjustment, maintaining both precision and stability.
3Adaptability or versatility
If a plate-shaped elastic member with bent sections is used, then novel configuration is achieved, but manufacturing complexity increases
Solution Approach 1:
The elastic member utilizes a thin plate structure with integrated bent sections, eliminating the need for complex assembly of multiple components. This monolithic plate design achieves novel configuration while simplifying manufacturing through single-piece forming processes, resolving the contradiction between configuration novelty and ease of manufacture.

AI summary
A torque wrench with elastic member includes a tubular body in which an elastic member is disposed for adjusting the torque value of the torque wrench. The elastic member is in the form of a plate body having a front connection section, a rear connection section and at least one bent section positioned between the front and rear connection sections. The front and rear connection sections of the elastic member respectively abut against a click mechanism disposed in front of the elastic member and an adjustment mechanism disposed behind the elastic member, whereby the elastic member can be compressed or released to adjust the torque value of the torque wrench. The elastic member has a novel structure and can ensure the stability of the torque wrench in use and enhance the utility of the torque wrench.
