Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the calibration device uses a traditional fixed structure, then it provides stable calibration functionality, but it occupies large space and is inconvenient to carry
Solution Approach 1:
The calibration device is divided into multiple independent segments including a stand assembly with adjustable legs, a beam assembly with rotatable beams, and a base assembly. Each segment can be independently folded or adjusted, allowing the device to be disassembled into compact components for easy transport while maintaining full functionality when assembled.
Solution Approach 2:
The device incorporates dynamic elements such as rotatable beams that can change orientation between horizontal and vertical positions, and adjustable legs that can be folded. These dynamic components allow the device to transition between a compact storage configuration and a fully extended calibration configuration, reducing occupied space during transport.
2Volume of moving object
If the calibration device is made portable and foldable, then it is convenient to carry and store, but it may compromise calibration stability and positioning accuracy
Solution Approach 1:
The foldable beams and bearing arms are designed to nest together when folded, with each component fitting within the structure of the previous component. This nesting arrangement minimizes the overall volume when stored while ensuring that all components are securely positioned and locked during calibration operations.
Solution Approach 2:
The device incorporates locking mechanisms and support structures that are activated before calibration begins to ensure stability. The adjustable legs can be positioned on stable surfaces beforehand, and the beams can be locked into fixed positions to prevent movement during the calibration process, compensating for the potential instability introduced by the foldable design.
