Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrodes without temperature sensors are mounted in the handpiece, then the handpiece structure is simpler, but the temperature control precision deteriorates and tissue damage occurs
Solution Approach 1:
The handpiece is divided into separable modules: handpiece body, electrode unit, and temperature sensor unit. The temperature sensor is independently mounted on the electrode unit rather than integrated into the handpiece structure, allowing precise temperature measurement at the surgical site while maintaining relatively simple handpiece construction.
Solution Approach 2:
A detachable coupling mechanism serves as an intermediary between the handpiece body and electrode unit. This coupling structure enables the temperature sensor to be positioned at the electrode unit for direct tissue contact while allowing the handpiece body to remain structurally simple and easily sterilizable.
2Ease of manufacture
If the handpiece is designed as a single integrated unit, then manufacturing is easier, but replacement of consumable parts becomes difficult
Solution Approach 1:
The handpiece is segmented into replaceable modules including the electrode unit and temperature sensor unit that can be detached from the handpiece body through a coupling mechanism. This allows consumable parts to be easily replaced while maintaining ease of manufacture through modular assembly.
Solution Approach 2:
The electrode unit and temperature sensor unit are designed as disposable or replaceable consumable parts that can be easily removed and replaced. The coupling mechanism enables efficient replacement of these consumable components without requiring replacement of the entire handpiece system.
3Device complexity
If the handpiece cannot be properly cleaned or autoclaved, then the structure can be simpler, but microorganism removal is inadequate
Solution Approach 1:
The handpiece is divided into separable components that can be individually autoclaved. The electrode unit and temperature sensor unit can be detached and sterilized separately, ensuring complete microorganism removal while maintaining relatively simple overall structure.
Solution Approach 2:
The electrode unit and temperature sensor unit are designed as disposable or easily replaceable components that can be autoclaved. This design ensures reliable microorganism removal through proper sterilization of consumable parts while avoiding complex sterilizable structures.
4Object-affected harmful factors
If repeated control work is performed to adjust high frequency output, then tissue damage can be minimized, but treatment time increases
Solution Approach 1:
The temperature sensor provides real-time feedback on the temperature at the surgical site during high frequency treatment. This feedback enables automatic adjustment of high frequency output to maintain optimal temperature, minimizing tissue damage while eliminating the need for repeated manual control adjustments and reducing treatment time.

AI summary
Disclosed herein is a surgical navigation instrument having a temperature sensor. The surgical navigation instrument can easily perform an autoclave action to remove microorganisms using saturated steam with respect to a part which can be contaminated during treatment, and enhance convenience in replacement of a grip part and the electrodes of the handpiece which are consumables, since a handpiece and electrodes are detachably screw-coupled with each other.
