Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the calibration device uses a fixed base structure, then the stability during calibration is improved, but the device occupies large space and is inconvenient to carry
Solution Approach 1:
The base structure is divided into multiple bearing arms that can be folded relative to each other. The bearing arms are rotatably connected to the bearing seat and can be folded towards the stand assembly, allowing the device to be compacted into a smaller volume for storage and transport while maintaining structural integrity during calibration operations
Solution Approach 2:
The bearing arms are designed with rotational joints that allow dynamic transformation between extended (calibration) and folded (storage) states. This dynamic structure enables the device to adapt its configuration based on operational requirements, providing both stability during use and compactness during transport
2Volume of moving object
If the calibration device uses a foldable base with rotating arms, then the space occupation is reduced, but the structural complexity increases
Solution Approach 1:
The bearing arms are designed to fold towards and nest against the stand assembly when not in use. This nesting arrangement minimizes the overall volume of the device during storage while using simple rotational connections rather than complex mechanisms, thereby reducing structural complexity
Solution Approach 2:
Instead of using a complex mechanism to achieve compactness, the invention uses simple rotational joints and the natural folding of arms towards the central stand. This inverted approach simplifies the structure by relying on basic mechanical principles rather than complex locking or actuating mechanisms
3Ease of operation
If the calibration device is designed for portability, then the ease of carrying is improved, but the stability during outdoor calibration may be compromised
Solution Approach 1:
The bearing arms are pre-configured with rotational joints that allow them to be quickly deployed into a stable extended position for calibration. The design anticipates the need for both portability and stability, preparing the structure in advance to transition smoothly between compact and operational states without compromising either requirement
