Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the insertion unit is made with a small diameter for minimum invasion, then the invasiveness is reduced, but the bending of the insertion unit occurs during insertion
Solution Approach 1:
The patent applies preliminary action by pre-calculating the bending amount based on insertion depth and tissue characteristics before the insertion is completed. The system predicts where the insertion unit will bend and compensates for this by adjusting the target location accordingly, ensuring accurate delivery despite the bending that will occur during insertion.
Solution Approach 2:
The patent implements feedback by continuously monitoring the insertion depth and tissue characteristics during the insertion process. The system uses this real-time information to adjust the predicted bending amount and modify the insertion operation dynamically, ensuring the insertion unit reaches the correct target location even as conditions change during insertion.
2Length of moving object
If the insertion unit is inserted deeply into the tissue, then the treatment depth is achieved, but the tissue surface displacement occurs
Solution Approach 1:
The patent applies preliminary action by predicting the tissue surface displacement based on the planned insertion depth and measured tissue characteristics before insertion begins. The system pre-calculates the compensation amount needed and adjusts the target location accordingly, so that even though displacement will occur during insertion, the insertion unit still reaches the correct effective treatment depth.
Solution Approach 2:
The patent implements feedback by measuring actual tissue characteristics during insertion and comparing them with predicted values. The system uses this feedback to adjust the displacement prediction and modify the insertion operation in real-time, ensuring accurate depth control despite variations in tissue properties encountered during the insertion process.
3Ease of operation
If the bending of the insertion unit is not compensated, then the insertion operation is simple, but the treatment effect is reduced or tissue is damaged
Solution Approach 1:
The patent applies self-service by enabling the insertion unit to sense its own bending state through integrated sensors and automatically adjust its insertion operation based on this self-diagnosis. The system performs its own correction without requiring external intervention, maintaining treatment accuracy while keeping the operator's task relatively simple.
Solution Approach 2:
The patent implements feedback by continuously monitoring the bending state of the insertion unit during insertion and using this information to automatically adjust the insertion operation. The system closes the control loop by comparing actual bending with predicted bending and making real-time corrections, ensuring reliable treatment delivery without complex manual compensation procedures.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables precise insertion of the treatment apparatus, improving treatment efficacy by ensuring accurate delivery of treatments to the target location while minimizing the risk of tissue damage.
Implementation Method 1
The bending sensing unit may be configured to sense whether the bending of the insertion unit occurs based on whether a support plate in which the insertion unit is positioned is inclined.
Implementation Method 2
The bending sensing unit may include a motion sensor positioned at a location close to the end of the handpiece and sensing whether the insertion unit has been bent.
