Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor is positioned inside the housing between the second part and the cover, then the sensor is protected and integrated into the structure, but the sensor becomes difficult to access for adjustment and calibration
Solution Approach 1:
The housing is divided into a first part containing the electric motor and a second part containing the motion transmission system, with the sensor positioned at the interface between these two parts. This segmentation allows the sensor to be accessible from the exterior while maintaining its integrated position within the housing structure.
Solution Approach 2:
The sensor is positioned at the interface between the second part of the housing and the cover, creating an intermediary access point. This allows adjustment of the sensor without requiring complete disassembly of the housing, as the sensor can be accessed by removing only the cover or by sliding the hood.
2Ease of repair
If the electromechanical actuator is fully assembled with the cover in place, then the device is protected and structurally complete, but adjustment of the sensor requires disassembly of the actuator
Solution Approach 1:
The hood is designed to slide relative to the second part of the housing, providing dynamic access to the sensor. This allows the hood to be moved to expose the sensor for adjustment while maintaining the overall assembled structure of the actuator, eliminating the need for complete disassembly.
Solution Approach 2:
The sensor is pre-positioned at the interface between the second part and the cover, where it can be accessed by simply removing the cover. This preliminary positioning allows for easy adjustment during installation and maintenance without requiring complex disassembly procedures.
3Volume of stationary object
If the sensor is located deep within the housing, then the internal structure is compact, but the sensor is not easily accessible for positioning and calibration
Solution Approach 1:
The sensor is positioned at the interface between the second part and the cover, utilizing the third dimension of the housing structure. This positioning allows the sensor to be accessible from the exterior while maintaining compact internal arrangement, as the sensor lies on the boundary surface between internal components and external access.
