Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If piezoelectric units are arranged in a rectangular shape, then the structure is simple and easy to manufacture, but vibration transmission along the longitudinal and diagonal directions cannot be isolated, resulting in noise and reduced detection accuracy
Solution Approach 1:
The piezoelectric unit is divided into multiple oblique units by forming cutting slots in oblique directions. This segmentation isolates the vibration transmission paths along different directions (longitudinal and diagonal) while maintaining a relatively simple manufacturing process. The cutting slots create separate vibration isolation regions without requiring complex structural modifications.
Solution Approach 2:
The cutting slots are formed in oblique directions rather than perpendicular to the lateral sides, creating an asymmetric structure within the piezoelectric unit. This asymmetric configuration effectively isolates vibration transmission along the longitudinal and diagonal directions, reducing noise and improving detection accuracy while preserving manufacturing simplicity.
2Ease of manufacture
If piezoelectric units are arranged in a rectangular shape, then the manufacturing process is simple, but vibration transmission along multiple directions cannot be isolated, resulting in noise
Solution Approach 1:
The piezoelectric unit is segmented into oblique units through oblique cutting slots, which creates distinct vibration isolation regions. This segmentation prevents vibration from propagating along multiple directions simultaneously, thereby reducing noise generation while maintaining manufacturing simplicity.
Solution Approach 2:
The oblique cutting slots create an asymmetric structure that selectively isolates vibration transmission along specific directions (longitudinal and diagonal). This asymmetric design effectively reduces noise by preventing multi-directional vibration propagation without complicating the manufacturing process.
3Measurement precision
If oblique cutting slots are formed to divide piezoelectric units into staggered oblique units, then vibration transmission along longitudinal and diagonal directions is isolated, but the structural complexity increases
Solution Approach 1:
The piezoelectric unit is divided into oblique units by forming cutting slots in oblique directions. This segmentation isolates vibration transmission paths along the longitudinal and diagonal directions, improving detection accuracy. The segmentation is achieved through relatively simple cutting slot formation rather than complex structural reconfiguration.
Solution Approach 2:
The oblique cutting slots create an asymmetric structure that effectively isolates vibration transmission along multiple directions. While this increases structural complexity compared to a simple rectangular arrangement, the asymmetry is achieved through straightforward cutting slot formation rather than complex multi-step manufacturing processes.
