Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If magnetic force is used to fasten the handpiece and cartridge housing, then the device can be assembled easily, but magnet detachment occurs during high-speed ultrasonic irradiation causing repeated irradiation
Solution Approach 1:
The patent combines magnetic force fastening with mechanical fastening structures. The handpiece and cartridge housing are fastened by both magnetic attraction and mechanical interlocking features, creating a dual-fastening system that maintains ease of assembly while preventing magnet detachment during high-speed operation.
Solution Approach 2:
The patent employs a composite fastening mechanism that integrates magnetic components with mechanical structural elements. This composite approach allows the system to benefit from both the ease of magnetic assembly and the reliability of mechanical connection, eliminating the detachment issue during ultrasonic irradiation.
2Device complexity
If the ultrasonic generator position is not accurately detected, then the device structure can be simpler, but thermal injury occurs due to inaccurate irradiation position
Solution Approach 1:
The patent implements a feedback control system where sensors continuously detect the ultrasonic generator's position, and the control device adjusts the irradiation parameters based on this real-time position information. This closed-loop feedback ensures accurate irradiation positioning, preventing thermal injury while maintaining a relatively simple overall device structure.
Solution Approach 2:
The patent replaces complex mechanical positioning systems with sensor-based detection and electronic control. Instead of using intricate mechanical mechanisms to ensure precise positioning, the system uses sensors to detect position and electronically controls the ultrasonic irradiation, achieving accurate positioning with reduced mechanical complexity.
3Productivity
If the ultrasonic generator moves at high speed, then the productivity is improved, but magnet detachment occurs causing repeated irradiation and potential accidents
Solution Approach 1:
The patent merges magnetic fastening with mechanical fastening structures to create a dual-fastening system. This combination allows the ultrasonic generator to move at high speed during irradiation while the mechanical interlocking features prevent magnet detachment, ensuring both high productivity and operational safety.
Solution Approach 2:
The patent incorporates redundant fastening mechanisms in advance to prevent magnet detachment. By combining magnetic and mechanical fastening before operation begins, the system is pre-prepared to withstand the forces generated during high-speed ultrasonic irradiation, preventing accidents and repeated irradiation.
4Ease of operation
If the driving device operates without position verification, then the operation is simpler, but damage to driving parts occurs due to inaccurate irradiation position
Solution Approach 1:
The patent implements a feedback mechanism where the control device verifies the ultrasonic generator's position before allowing the driving device to operate. Sensors provide real-time position information to the control system, which only permits driving device operation when the position is confirmed accurate, preventing damage to driving parts while maintaining operational simplicity.
Solution Approach 2:
The patent performs position verification before initiating driving device operation. The control device checks the ultrasonic generator's position in advance using sensor data, and only allows the driving device to operate when positioning is confirmed. This preliminary verification prevents driving part damage while keeping the operation process simple and intuitive.
