Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weighing sensor is fixed separately in equipment with corresponding connection structure, then weighing function can be achieved, but device complexity increases and installation becomes difficult
Solution Approach 1:
The patent combines the support leg and weighing sensor into a single integrated unit. The elastic body serves dual purposes: providing mechanical support and enabling weighing measurements. This merging eliminates the need for separate weighing sensor installation and connection structures, thereby reducing device complexity while maintaining weighing functionality.
Solution Approach 2:
The support leg is designed with multi-functionality, serving both as a mechanical support structure and as a weighing sensor. The elastic body within the support leg simultaneously provides structural support and measures weight through its deformation characteristics, allowing one component to fulfill multiple functions.
2Measurement precision
If weighing sensor is installed separately in equipment, then weighing measurement can be performed, but installation position errors occur reducing measurement accuracy
Solution Approach 1:
By integrating the weighing function directly into the support leg, the patent eliminates the separate installation step that causes position errors. The weighing measurement point is inherently aligned with the support function, ensuring accurate measurements without requiring precise installation procedures.
3Ease of manufacture
If support leg and weighing sensor are independent components, then each can be optimized separately, but installation and modification become time-consuming
Solution Approach 1:
The integration of support leg and weighing sensor into a single unit reduces the number of components to be installed. This merging decreases installation time and simplifies modification processes, as only one integrated component needs to be handled rather than multiple separate parts.
Solution Approach 2:
The support leg is designed as a modular unit with the elastic body integrated within it. This segmentation allows the entire support-weighing assembly to be manufactured as a standardized module that can be easily installed and replaced, reducing installation time while maintaining manufacturing flexibility.
4Ease of manufacture
If separate connection structure is provided for weighing sensor, then weighing sensor can be connected, but design complexity of equipment increases
Solution Approach 1:
The patent merges the connection function into the support leg structure itself. The upper end of the support leg directly provides the connection interface, eliminating the need for separate connection structures. This integration simplifies the overall equipment design while maintaining ease of manufacture for the connection interface.
