Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensors are mounted outside the power system for motion control, then the control function can be realized, but the sensors become vulnerable to accidental damage during maintenance
Solution Approach 1:
The patent integrates the sensing components directly into the power transmission system by mounting the sensed member on the transmission belt and the sensing member on the support structure within the enclosed space. This merging of sensing function with the existing mechanical structure eliminates the need for separate external sensors, thereby protecting them from damage during maintenance while maintaining the control function.
Solution Approach 2:
The patent introduces an intermediary sensing mechanism where the sensing member and sensed member interact through the mechanical structure itself. The sensed member mounted on the transmission belt serves as an intermediary that translates the position information into detectable signals, allowing control without exposing external sensors to damage risks.
2Measurement precision
If external sensors are used for position detection, then motion stroke control can be achieved, but equipment failure probability increases due to sensor damage
Solution Approach 1:
The sensing system is merged with the mechanical structure by integrating the sensed member directly onto the transmission belt and the sensing member onto the support structure. This integration ensures that position detection is achieved through the mechanical components themselves, eliminating the need for vulnerable external sensors while maintaining measurement precision.
Solution Approach 2:
The mechanical structure serves its dual function of both power transmission and position sensing. The transmission belt and support structure, which already exist for mechanical operation, are utilized to mount the sensing components, allowing the system to sense its own position without requiring separate external sensing systems that could be damaged.

AI summary
The present invention discloses a mechanical equipment. The sensing member and the sensed member are mounted on the power device, and one of the sensing member and the sensed member is mounted on the output mechanism to move periodically as the output mechanism moving periodically. When each time the sensing member and the sensed member are located relatively at a predetermined position, the control device receives the sensing signal generated when the sensing member senses the sensed member and sends a predetermined control command to the power mechanism when the sensing signals received by the control device reach the threshold value. Therefore, the present invention can achieve controlling the working state of the mechanical equipment and reduce the failure probability of the mechanical equipment at the same time.
