Hand Dynamometer Integrated Structure Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand dynamometers face issues with the side cover being damaged under high tension due to the snapping attachment method, and the assembly process is cumbersome with multiple parts.
Innovation Solution
An integrated side cover structure is proposed, where the side cover is directly integrated into the main body to form a single, stronger unit, reducing assembly steps and enhancing manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the side cover is attached to the main body by snaps, then the assembly process is simple, but the side cover may bulge or be damaged when the pulling force exceeds 100 kilograms
Solution Approach 1:
The side cover and main body are merged into a single integrated structure through injection molding, eliminating the separate snap attachment connection. This integration ensures that the side cover and main body form a unified whole that can withstand high pulling forces without bulging or detaching, while maintaining ease of manufacturing through one-step molding.
2Adaptability or versatility
If the main body is composed of front shell and rear shell assembled together, then the manufacturing flexibility is improved, but the assembly process becomes cumbersome
Solution Approach 1:
The front shell, rear shell, and side cover are merged into a single integrated main body structure through injection molding. This eliminates the need for assembling multiple separate components, significantly simplifying the assembly process while maintaining manufacturing flexibility through mold design variations.
3Ease of repair
If the side cover is made as a separate component, then the repairability is improved, but the overall strength and structural integrity are reduced
Solution Approach 1:
The side cover is merged with the main body into an integrated structure that maintains high structural integrity and resistance to pulling forces. While repairability of the integrated structure may be slightly reduced compared to separate components, the overall structural stability and strength are significantly improved, preventing bulging and detachment under load.

AI summary
The present invention discloses a hand dynamometer structure, comprising a housing, a sensor element provided within the housing, and a gripping part connected to the sensor element. The housing includes a main body having an installation cavity, a connection port at the lower part, and guide members on both sides. The gripping part is positioned between and movable relative to the guide members. The main body and the guide members form an integrated structure. An installation opening is formed at the front or rear side of the main body, with a cover plate at the installation opening. The side wall of the main body is provided with an information screen opening and button openings communicating with the installation cavity. Compared to the prior art, the present invention integrates the side cover directly into the main body, effectively improving the overall strength and reducing the assembly steps, which improves production efficiency.
