Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic force is used to lock surgical instrument, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical locking mechanisms with a magnetic locking system. The movable magnet unit interacts with stationary magnet units through magnetic attraction and repulsion forces to achieve locking and unlocking of the surgical instrument, eliminating the need for complex mechanical components such as springs, cam mechanisms, or manual locking tools.
Solution Approach 2:
The magnetic locking system operates autonomously through the interaction between movable and stationary magnet units. The system self-regulates the locking and unlocking states based on the relative positions and magnetic polarities of the magnet units, without requiring external control mechanisms or manual intervention.
2Ease of operation
If magnetic force is used to lock surgical instrument, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies different magnetic pole configurations to different regions of the magnet units. The movable magnet unit has its magnetic pole arranged to interact with specific stationary magnet units at different positions, creating localized magnetic fields that provide direction-specific locking and unlocking forces without requiring high precision across the entire device.
Solution Approach 2:
The magnetic locking system is divided into multiple stationary magnet units positioned at different locations, each interacting with the movable magnet unit independently. This segmentation allows the system to achieve reliable locking through cumulative magnetic effects from multiple units, reducing the precision requirement for each individual unit.
3Productivity
If alternating attractive and repulsive forces are used, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent employs periodic magnetic force application through the alternating attraction and repulsion between movable and stationary magnet units. By strategically positioning magnetic poles, the system generates sequential magnetic force cycles that automatically drive the rapid installation and uninstallation of the surgical instrument, achieving high-speed operation through periodic magnetic interactions rather than continuous force application.

AI summary
The present invention relates to an apparatus for locking a surgical instrument by using magnetic force and, more specifically, to an apparatus for locking a surgical instrument by using magnetic force, which installs or uninstalls an instrument for microsurgery by using magnetic force in order to reduce a load that may occur during installing/uninstalling an instrument for microsurgery. To this end, disclosed is the apparatus for locking a surgical instrument by using magnetic force, comprising: a first magnetic force unit which forms a locking magnetic force when moving in a locking direction so that an attractive force is applied in a different direction from the locking direction and a locking operation is performed, and forms a release magnetic force when moving in a release direction so that a repulsive force is applied in a different direction from the release direction and an unlocking operation is performed; a second magnetic force unit which is fixed and forms the locking magnetic force and the release magnetic force by interacting with the first magnetic force generation unit; and a locking unit which is locked or unlocked due to the attractive force and the repulsive force generated by the first and second magnetic force units when moving in the locking direction and the release direction, so as to install and uninstall the surgical instrument.
