Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal attachment unit is produced to fit different mobile terminal shapes and sizes, then compatibility with various devices is improved, but the structure becomes complicated due to the need for adjustability
Solution Approach 1:
The attachment unit is divided into a first attachment unit for physical attachment and a second attachment unit for electrical connection. This segmentation allows each unit to be optimized independently - the first unit provides universal mechanical attachment through a standardized interface, while the second unit handles device-specific electrical connections, thereby reducing overall structural complexity while maintaining compatibility.
Solution Approach 2:
The first attachment unit is designed as a universal mechanical attachment interface that can physically secure various mobile terminals to the peripheral device regardless of their shape or size. This universal mechanical interface simplifies the attachment mechanism while the electrical connection is handled separately through the second attachment unit, avoiding the need for a complex universal electrical interface.
2Ease of operation
If wireless connection mode is used to connect peripheral device and mobile terminal, then convenience is improved, but the ability to maintain power source is limited
Solution Approach 1:
The system merges wireless communication capabilities with wired power transfer capabilities in a single integrated connection interface. When the mobile terminal is physically attached to the peripheral device, the electrical connection is automatically established, enabling simultaneous wireless data communication and wired power supply, thus eliminating the need for separate charging cables or power adapters.
3Shape
If charging cable is positioned inside the peripheral device for position correction, then appearance is improved, but the risk of breaking the charging cable increases due to repetitive movement
Solution Approach 1:
The charging cable function is extracted from the mobile terminal and integrated into the peripheral device's attachment unit. The electrical connection interface is built into the peripheral device, eliminating the need for a separate charging cable that requires repeated insertion and movement. This extraction resolves the conflict by providing a fixed, reliable connection point within the peripheral device while maintaining a clean appearance.
