Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable or wire connections are used for accessory interfaces, then electrical connection reliability is improved, but device volume and housing space are increased
Solution Approach 1:
The patent replaces traditional mechanical cable/wire connections with a magnetic field-based wireless power and data transmission system. The magnetic resonance coupling between the radio's transmitter coil and the accessory's receiver coil enables electrical connection without physical cables, thereby maintaining reliability while reducing housing space requirements.
Solution Approach 2:
The patent implements a universal interface system that can accommodate multiple types of accessories (audio devices, charging accessories, gaming devices) through a single magnetic interface. This multi-functional approach eliminates the need for multiple specialized cable connections, reducing overall housing space while maintaining reliable electrical connection for various accessory types.
2Adaptability or versatility
If multiple accessory interface points are placed on outer surfaces, then adaptability to different accessories is improved, but device complexity and user confusion are increased
Solution Approach 1:
The patent employs a single universal magnetic interface that supports multiple accessory types through automatic detection and adaptive configuration. The system can identify whether an accessory is an audio device, charging device, or gaming device and automatically adjust communication protocols, thereby maintaining high adaptability while simplifying the physical interface to a single location.
Solution Approach 2:
The interface system automatically detects the type of accessory connected and configures the appropriate communication mode without user intervention. The radio's controller automatically adjusts parameters such as power transmission level, data protocol, and audio routing based on the detected accessory type, eliminating user confusion while maintaining versatility.
3Use of energy by moving object
If cable connections are used, then power transmission capability is improved, but ease of operation is reduced due to entanglement and length adjustment needs
Solution Approach 1:
The patent replaces mechanical cable-based power transmission with wireless magnetic resonance power transfer. The radio's transmitter coil generates a magnetic field that induces current in the accessory's receiver coil, enabling power transmission without cables. This eliminates entanglement issues and length adjustment needs while maintaining adequate power transmission capability for accessory operation.
4Ease of operation
If accessory interfaces are placed on outer housing surfaces, then ease of accessory attachment is improved, but available housing space for other components is reduced
Solution Approach 1:
The patent replaces traditional external mechanical connectors with an integrated magnetic interface system. The magnetic coils are embedded within the housing, and accessories attach through magnetic attraction rather than mechanical insertion. This maintains ease of attachment while freeing up external housing space and allowing more flexible internal component layout.
