Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If expansion modules are added to mobile device, then device functionality is improved, but device complexity increases
Solution Approach 1:
The mobile device system is divided into a main body and detachable expansion modules. Each expansion module is an independent functional unit that can be attached or detached as needed. This segmentation allows the device to gain additional functionality through modular addition rather than integrating all features into a single complex unit, thereby improving adaptability while managing complexity through standardized interfaces and independent module design.
2Ease of operation
If magnetic coupling is used for module attachment, then ease of operation is improved, but magnetic interference increases
Solution Approach 1:
Magnetic shielding materials are strategically positioned at specific locations where magnetic fields are strongest, particularly around the coupling elements and sensitive electronic components. This localized application of shielding properties allows the magnetic coupling mechanism to function effectively for easy attachment and detachment while minimizing magnetic interference in critical areas, thus maintaining ease of operation without excessive magnetic interference.

Implementation Method 1
a magnet disposed to apply a magnetic force to the coupling element to couple the expansion module with the main body
Implementation Method 2
a movement converter configured to move the magnet away from the coupling element so as to decrease the magnetic force between the coupling element and the magnet thereby decoupling the main body from the expansion module
