Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical physical fastening means are used to connect accessories, then connection strength is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces mechanical physical fastening means with magnetic coupling to connect accessories to the device. The magnetic coupling mechanism uses magnetic attraction forces instead of mechanical fasteners, reducing structural complexity while maintaining connection strength. This substitution eliminates the need for screws, clips, or other mechanical attachment mechanisms.
Solution Approach 2:
The patent utilizes magnetic field strength as a controllable parameter to achieve secure connection. By adjusting magnetic coupling strength through magnet selection and positioning, the system achieves adequate connection force without mechanical fastening, thereby simplifying the overall device structure while maintaining attachment reliability.
2Measurement precision
If specialized remote controllers are used for each device, then control precision is improved, but adaptability and ease of operation deteriorate
Solution Approach 1:
The patent implements a universal remote control system using magnetic coupling that can interface with multiple different devices and accessories. The magnetic coupling mechanism serves as a standardized interface that works across various device types, eliminating the need for device-specific controllers while maintaining effective control capability through the universal magnetic interface.
3Reliability
If mechanical fastening means are used, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces mechanical fastening operations with magnetic attachment, allowing accessories to be connected simply by bringing them into proximity with the device. The magnetic force automatically secures the connection without requiring manual fastening operations, significantly improving ease of operation while maintaining reliable attachment through the magnetic bond.
