Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between transmitting and receiving probes is fixed, then the device structure is simple, but the measurement adaptability is reduced for different materials and directions
Solution Approach 1:
The patent implements a dynamic distance adjustment mechanism between the transmitting and receiving probes, allowing the distance to be changed according to different measurement requirements. This enables the device to adapt to different materials and measurement directions while maintaining a relatively simple overall structure through a scalable connection design.
2Measurement precision
If the deflection angles of transmitting and receiving transducers are adjusted separately, then the adjustment flexibility is high, but the angle consistency cannot be ensured and measurement sensitivity is reduced
Solution Approach 1:
The patent combines the angle adjustment mechanisms of the transmitting and receiving transducers into a unified adjustment system. By merging the adjustment operations, the device ensures that both transducers maintain consistent deflection angles, thereby improving measurement sensitivity while simplifying the adjustment process to a single coordinated operation.
Solution Approach 2:
The patent incorporates feedback mechanisms that monitor and ensure the deflection angles of both transducers remain consistent. This feedback control allows the system to automatically maintain angle synchronization, improving measurement precision while reducing the operational burden on the user.
3Measurement precision
If different oblique incident devices are machined for different materials, then the measurement accuracy is improved, but the measurement cost is increased
Solution Approach 1:
The patent designs a universal measuring device with adjustable parameters that can accommodate different materials and measurement requirements. Instead of manufacturing separate specialized devices for each material, this multi-functional device achieves the same measurement accuracy through adjustable distance and angle parameters, significantly reducing manufacturing costs while maintaining precision.
