Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a torque amplifier is used to increase torque output, then the torque capability is improved, but the automatic release functionality is lost and torque precision deteriorates
Solution Approach 1:
The release mechanism is nested within the torque amplifier structure. The release valve is positioned inside the torque amplifier housing, and the transmission members are contained within the driving member. This nested arrangement allows the torque amplifier to maintain its torque multiplication function while integrating the release mechanism without requiring separate external components.
Solution Approach 2:
The release mechanism uses feedback from the torque transmission process itself. When the torque reaches a predetermined value, the transmission members automatically push the release valve, which then releases the locking balls to disengage the driving member from the transmission members. This feedback-based automatic release ensures precise torque control without requiring external monitoring or manual intervention.
2Device complexity
If a torque amplifier with fixed reduction ratio is used, then the structure is simplified, but torque precision deteriorates due to difference between calculated and real torque values
Solution Approach 1:
The system uses itself to determine the release torque. Rather than relying on pre-calculated theoretical values, the actual torque transmission process generates the release signal. The transmission members directly interact with the release valve based on the real-time torque being transmitted, making the system self-regulating and eliminating the discrepancy between calculated and actual torque values.
Solution Approach 2:
The release mechanism allows for adjustable torque thresholds. By modifying the spring force or the geometry of the release valve, the predetermined torque value for release can be changed. This parameter adjustability enables the system to adapt to different torque requirements while maintaining structural simplicity.
3Ease of operation
If conventional torque wrench operation is used without automatic release, then operational control is maintained, but productivity deteriorates due to repeated manual operations
Solution Approach 1:
The automatic release mechanism enables periodic action in the fastening process. After each torque application reaches the predetermined value and automatically releases, the driving member can be immediately re-engaged by rotating it in the opposite direction and then forward again. This periodic cycle of engagement-torque application-release can be repeated rapidly without manual intervention between cycles, significantly increasing fastening productivity while maintaining precise torque control.
