Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If magnetic force is increased to hold components securely, then attachment strength is improved, but detachment effort increases
Solution Approach 1:
The magnetic force is made dynamically adjustable through an actuator mechanism that can change the spacing between magnetic components. The system transitions from a static magnetic force to a dynamic one that can be increased for secure attachment and decreased for easy detachment, resolving the contradiction between strong attachment and easy release.
Solution Approach 2:
The magnetic force parameter is changed by physically adjusting the spacing between magnetic components using an actuator. By changing this physical parameter (distance), the system can modulate the magnetic force strength to achieve both strong attachment when needed and weak attachment for easy detachment.
2Device complexity
If fixed magnetic force is used, then device simplicity is improved, but user customization capability deteriorates
Solution Approach 1:
The system incorporates a controllable actuator that enables dynamic adjustment of magnetic force based on user input or system state. This transforms a simple fixed-force design into an adaptable system that can provide different magnetic force levels for different users or situations without significantly complicating the overall device architecture.
3Stability of the object's composition
If magnetic components are held together by strong magnetic force, then connection stability is improved, but safety risk increases due to difficulty of separation
Solution Approach 1:
The system changes the magnetic force parameter from a permanently high value to a controllable variable. The actuator mechanism allows the magnetic force to be increased for stable connection during normal use and decreased when separation is needed, eliminating the safety risk associated with permanently strong magnetic forces while maintaining connection stability when required.

AI summary
Magnetic force adjustment mechanisms are described herein. An electronic device includes a base, a first magnet carried by the base, a lid and a second magnet carried by the lid. The first and second magnets secure the base and the lid together with a holding force. A hinge pivotally couples the lid and the base. A slider displaces at least one of the first or second magnets relative to the other of the first or second magnets to reduce the holding force.
