Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a trial and error approach is used to adjust fastening force, then the fastening force can be adjusted, but the process becomes laborious and time-consuming
Solution Approach 1:
The clamp mechanism is pre-configured with an adjustment mechanism that allows the fastening force to be set to a predetermined value before use. This eliminates the need for trial and error adjustments during operation, as the correct fastening force can be established in advance through the adjustment mechanism.
Solution Approach 2:
The clamp mechanism incorporates a feedback system where the adjustment mechanism allows users to monitor and verify the fastening force. This feedback capability enables precise control of the fastening force without requiring multiple trial and error adjustments, significantly reducing the time needed for setup.
2Reliability
If excessive fastening force is applied to secure the motor unit, then the motor unit is firmly attached, but the fastening unit and motor unit may be damaged
Solution Approach 1:
The clamp mechanism allows for precise control of the fastening force parameter through the adjustment mechanism. Users can set the fastening force to a predetermined optimal value that provides secure attachment without exceeding the damage threshold of the motor unit or fastening components. This parameter control capability eliminates the risk of damage while ensuring reliable attachment.
Solution Approach 2:
The clamp mechanism is designed with a cushioning effect through its spring-loaded or compliant clamping surfaces, which prevent excessive force from being transmitted to the motor unit. This beforehand cushioning protects the motor unit from damage while still providing firm attachment, eliminating the harmful effect of excessive fastening force.
3Ease of operation
If insufficient fastening force is applied to secure the motor unit, then the motor unit is easily attached, but the motor unit may rattle or vibrate resulting in imprecise cuts
Solution Approach 1:
The adjustment mechanism allows precise control of the fastening force parameter to achieve the optimal value that eliminates rattling and vibration. By accurately setting the fastening force parameter, the system ensures both easy attachment and precise cuts, resolving the contradiction between ease of operation and manufacturing precision.
Solution Approach 2:
The clamp mechanism replaces manual trial and error adjustment with a mechanical adjustment system that provides precise control of fastening force. This mechanical substitution enables accurate setting of the optimal fastening force, eliminating vibrations and ensuring precise cuts while maintaining ease of operation.
4Device complexity
If a simple clamp mechanism is used to secure the motor unit, then the attachment process is simple, but the fastening force cannot be accurately adjusted
Solution Approach 1:
The clamp mechanism incorporates a dynamic adjustment mechanism that allows the fastening force to be modified during operation. This dynamic capability enables accurate control of the fastening force parameter while maintaining a relatively simple overall structure. The adjustment mechanism can be engaged or disengaged as needed, providing precision without excessive complexity.
Solution Approach 2:
The clamp mechanism is segmented into a simple clamping structure and a separate adjustment mechanism. This segmentation allows the basic clamp structure to remain simple while the adjustment mechanism provides precise control of fastening force. The two components work together to achieve both simplicity and accuracy without requiring a completely complex integrated design.
