Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional rulers and tape measures are used, then they are simple in structure and low in cost, but they cannot accurately measure objects with uneven and complex outlines due to limited curvature
Solution Approach 1:
The patent employs a roller-shaped measuring body with a cylindrical curvature that can conform to uneven and complex object surfaces. The roller's curved surface allows it to adapt to various contours, enabling accurate measurement of objects that traditional flat rulers and tape measures cannot handle effectively.
Solution Approach 2:
The patent removes the complex transmission components (gears, belts, or chains) from the electronic roller scale design. Instead, it uses a direct connection where the roller rotates on a mounting axis that is directly coupled to the measuring mechanism, eliminating intermediate transmission parts that complicate the structure and reduce measurement accuracy.
2Measurement precision
If electronic roller scales with transmission parts are used, then measurement capability is improved, but internal structure becomes complex and assembly cost increases
Solution Approach 1:
The patent extracts and removes the transmission components (gears, belts, or chains) that are typically present in electronic roller scales. The design directly connects the roller to the measuring mechanism through a mounting axis, eliminating the need for complex transmission systems and reducing assembly complexity and cost.
Solution Approach 2:
The patent merges the roller, mounting axis, and measuring mechanism into a more integrated structure. The roller is directly mounted on the axis that serves as both the rotation support and the measurement reference, combining functions that were previously separated into distinct transmission components.
3Measurement precision
If electronic roller scales with transmission parts are used, then measurement capability is improved, but transmission part accuracy affects overall measurement accuracy
Solution Approach 1:
The patent removes the transmission components that introduce accuracy errors. By eliminating gears, belts, or chains, the design ensures that the roller's rotation is directly and accurately transmitted to the measuring mechanism without the cumulative errors that arise from multiple transmission stages.
Solution Approach 2:
The mounting axis serves as a direct intermediary between the roller and the measuring mechanism, providing a rigid and precise connection that accurately transfers rotational motion without the flexibility or play introduced by transmission components.
4Device complexity
If a roller-shaped measuring body with mounting axis is used, then structure is simplified and assembly cost is reduced, but the device must be clamped for operation
Solution Approach 1:
The measuring device is designed with clamping bases that enable it to be securely attached to various surfaces and objects. This clamping capability provides a stable mounting platform that allows the roller to function accurately on diverse surfaces, while the overall simple structure maintains ease of manufacture and assembly.
