Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional high frequency treatment devices are used to insert needles into sensitive areas like eyes, nose, or neck, then the treatment can be applied to these areas, but it is difficult to insert a plurality of needles to uniform depth or in a fixed direction and difficult to make the needles penetrate tissues
Solution Approach 1:
The device applies suction to the treatment area before needle insertion, creating a vacuum that holds the tissue firmly against the treatment head. This preliminary action stabilizes the tissue and provides a consistent starting point for needle insertion, enabling uniform penetration depth and direction across multiple needles even in sensitive areas like eyes, nose, and neck.
Solution Approach 2:
The suction mechanism acts as an intermediary between the treatment device and the tissue. By creating a vacuum field, it mediates the interaction between the needles and tissue, ensuring consistent contact and penetration conditions without requiring manual pressure control by the operator.
2Reliability
If high frequency needles are inserted to various depths at the same position to improve treatment effect, then treatment efficacy is enhanced, but the device complexity increases to accommodate depth adjustment mechanisms
Solution Approach 1:
The device incorporates adjustable needle penetration depth mechanisms that allow dynamic adjustment of needle depth during treatment. The treatment head can be configured to insert needles to different depths at the same position, enabling enhanced treatment efficacy while maintaining a relatively simple overall device structure through modular depth adjustment capabilities.
3Measurement precision
If impedance detection is implemented to control high frequency energy output according to tissue impedance, then treatment precision is improved, but the device complexity increases due to additional detection and control systems
Solution Approach 1:
The device incorporates an impedance detection unit that continuously monitors tissue impedance during high frequency treatment. The control unit receives impedance signals and automatically adjusts the high frequency energy output accordingly, creating a closed-loop feedback system that improves treatment precision while managing complexity through integrated control algorithms.
Solution Approach 2:
The impedance detection and control system operates autonomously, with the control unit automatically adjusting treatment parameters based on real-time impedance measurements without requiring manual intervention. This self-regulating mechanism improves precision while minimizing the operational complexity for the user.
