Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a display device is coupled to a stand using magnetic attraction force, then the display device can be securely held in place, but it becomes difficult to detach the display device from the stand
Solution Approach 1:
The patent applies asymmetry by positioning magnets at different distances from the edges of the display device. Specifically, magnets are located closer to the long edges than to the short edges, creating asymmetric magnetic attraction forces. This asymmetry allows the device to be securely held when attached properly, while enabling easier detachment by applying force at the long edges where the magnetic attraction is weaker.
Solution Approach 2:
The patent implements local quality by varying the magnetic attraction strength at different locations on the display device. The magnetic attraction force is stronger near the short edges and weaker near the long edges due to the differential positioning of magnets. This localized variation in magnetic force allows for secure overall coupling while providing specific detachment points at the long edges.
2Reliability
If the display device is held firmly to the stand, then stable electrical connections are maintained, but orientation transitions between landscape and portrait modes become difficult
Solution Approach 1:
The asymmetric magnet positioning creates weaker magnetic attraction at the long edges, which serves as detachment points. This asymmetry enables users to easily initiate orientation transitions by applying force at the long edges, while the overall magnetic coupling remains strong enough to maintain stable electrical connections during normal operation.
Solution Approach 2:
The magnetic coupling system allows for dynamic interaction between the display device and stand. The asymmetric magnetic forces enable the device to be held firmly in stable orientations (landscape and portrait) while allowing controlled transitions between these orientations by applying force at the weaker magnetic attraction points.
3Reliability
If symmetric magnetic attraction is used, then the display device is held securely in all orientations, but detachment requires excessive force in all directions
Solution Approach 1:
The patent directly addresses this contradiction by creating asymmetric magnetic attraction forces through differential magnet positioning. The magnets are positioned closer to the long edges than to the short edges, resulting in weaker magnetic attraction at the long edges. This asymmetry provides easy detachment points while maintaining secure holding in other areas.
Solution Approach 2:
The patent implements local quality by creating spatial variation in magnetic attraction strength. The magnetic force is stronger near the short edges and weaker near the long edges, allowing the device to be held securely overall while requiring less force for detachment at specific locations.
