Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the insertion force is weakened to facilitate fastening between the two connectors, then the ease of operation is improved, but the coupling force between the two connectors is weakened, making it difficult to stably maintain the coupled state
Solution Approach 1:
The patent replaces the traditional mechanical fastening system with a magnetic field-based fastening system. The magnetic unit generates magnetic attraction force to hold the connectors together, eliminating the need for complex mechanical locking mechanisms. This substitution allows for easy insertion while maintaining stable coupling through magnetic force.
Solution Approach 2:
The patent employs a movable second magnet that can change position to adjust the magnetic field strength. When the connector is inserted, the magnet moves to create strong magnetic attraction for stable coupling. When separation is needed, the magnet moves to reduce magnetic force, enabling easy detachment. This dynamic parameter change resolves the contradiction between stable coupling and easy separation.
2Reliability
If the coupling force between the two connectors is excessively high to stably maintain the coupled state, then the reliability is improved, but a lot of force is required when coupling between the two connectors, and separation becomes difficult
Solution Approach 1:
The patent makes the magnetic field dynamic through the movable second magnet. The magnetic attraction force is not fixed but can be adjusted by the position of the second magnet. During insertion, the magnet creates strong attraction for stable coupling. During separation, the magnet moves to reduce attraction, making detachment easy. This dynamic adjustment resolves the contradiction between strong coupling and easy separation.
Solution Approach 2:
The magnetic unit automatically adjusts the magnetic field strength based on the operational state. When connectors are coupled, the magnetic field naturally provides strong attraction for stability. When separation is attempted, the system allows the magnet to move and reduce magnetic force, enabling easy detachment without requiring excessive external force.
3Ease of operation
If a magnetic unit with movable multi-pole magnets is used to enable adjustable magnetic forces for easy coupling and stable connection, then the ease of operation and reliability are improved, but the device complexity increases
Solution Approach 1:
The magnetic unit is divided into two separate magnets: a first magnet fixed to the housing and a second magnet that is movable. This segmentation allows each magnet to have a specific function - the first magnet provides the base magnetic field, while the second magnet adjusts the field strength. This division simplifies the overall design compared to a single complex adjustable magnet system.
