Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate sensors are used to measure different physical variables (rotational speed, acceleration), then measurement coverage is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple sensor elements (first sensor element for rotational speed, second sensor element for acceleration) into a single micromechanical element with a common housing. This merging approach allows the device to measure different physical variables simultaneously while reducing overall device complexity and space requirements compared to using separate sensors for each measurement function.
Solution Approach 2:
The micromechanical element is designed as a universal sensor unit that can perform multiple measurement functions through its different sensor elements. The first sensor element measures rotational speed while the second sensor element measures acceleration, allowing a single device to serve multiple measurement purposes and improve adaptability without requiring separate specialized sensors for each function.
