Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed clamping force is applied to the diamond crystal, then the crystal is securely held in position, but thermal contact is limited and crystal strain increases
Solution Approach 1:
The patent transforms the fixed clamping force into a dynamic, adjustable clamping force using a piezoelectric actuator. This allows the clamping force to be optimized in real-time to achieve both secure positioning and improved thermal contact, resolving the contradiction between reliability and temperature management.
Solution Approach 2:
The patent changes the clamping force parameter from a fixed value to a dynamically adjustable range (0-50 grams). This parameter change enables optimization of both crystal positioning stability and thermal contact efficiency by selecting appropriate force levels for different operational requirements.
2Temperature
If increased clamping force is applied to improve thermal contact, then thermal contact improves, but crystal strain increases
Solution Approach 1:
The piezoelectric actuator enables dynamic adjustment of clamping force, allowing the system to apply optimal force for thermal contact without exceeding the threshold that would cause crystal strain. The force can be precisely controlled and adjusted based on real-time conditions.
Solution Approach 2:
The patent implements feedback control where the clamping force is adjusted based on monitoring of crystal conditions. This feedback mechanism prevents excessive force application that would cause strain while maintaining sufficient force for optimal thermal contact.
3Temperature
If manual adjustment of clamping force is used, then thermal contact can be optimized, but remote dynamic control is not achieved
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated piezoelectric actuator system. This substitution enables remote and dynamic control of clamping force through electrical signals, eliminating the need for manual intervention while maintaining optimal thermal contact.
Solution Approach 2:
The piezoelectric actuator provides dynamic control capability, allowing the clamping force to be adjusted remotely and in real-time according to operational requirements, thus achieving both thermal optimization and remote control.
4Stress or pressure
If sliding fit holder design is used, then crystal strain is minimized, but thermal contact is limited
Solution Approach 1:
The patent enhances the sliding fit holder by adding dynamic clamping force control. This allows the system to maintain the low-strain benefits of sliding fit while achieving optimized thermal contact through adjustable clamping force applied by the piezoelectric actuator.
Solution Approach 2:
The patent merges the sliding fit holder design with a piezoelectric actuator system. This combination integrates the strain-minimizing geometry of sliding fit with the thermal-optimizing capability of active clamping force control.
