Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weighing sensors for electronic balances face challenges such as complex processing and assembly processes, large volume, high costs, and instability due to their die casting structure, which complicates the assembly of levers and affects precision and cost-effectiveness.
Innovation Solution
A weighing sensor design featuring a load-receiving portion, a fixing portion, and a parallel guiding portion with an extension that allows the lever to pass through, simplifying assembly by integrating components and reducing the number of parts, facilitating processing, and reducing production costs through a more straightforward assembly method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a die casting structure is used for the weighing sensor, then the structural strength is improved, but the volume becomes large, the number of parts increases, and the assembly complexity increases
Solution Approach 1:
The patent integrates multiple components (lever, guiding sheets, support structures) into a single integrated weighing sensor body, eliminating the need for separate joint elements and reducing assembly complexity while maintaining structural strength through unified die casting
2Volume of moving object
If a highly integrated single-module weighing sensor structure is used, then the volume is reduced, but the processing process becomes complicated and the assembly becomes inconvenient
Solution Approach 1:
The integrated weighing sensor body is designed with distinct functional zones (load-receiving portion, parallel guiding portion, fixing portion) that can be processed separately and then assembled through standardized connection interfaces, simplifying the manufacturing process while maintaining integration benefits
3Ease of operation
If the lever is assembled from the periphery of the sensor, then the assembly process is simplified, but the lever size becomes large and it is easily influenced by external factors
Solution Approach 1:
The lever is nested within the integrated weighing sensor body, with the parallel guiding portion providing internal support and constraint. This internal positioning protects the lever from external influences while maintaining assembly simplicity through the integrated structure
4Device complexity
If the lever and sensor body are integrally formed, then the assembly problem is resolved, but the production cost increases and production flexibility decreases
Solution Approach 1:
The weighing sensor is designed as an integrated body with distinct modular sections that can be manufactured using standardized die casting processes. This segmentation allows for efficient production through template-based manufacturing while maintaining the structural benefits of integration
