Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ceramic materials with different colors are used for housing, then color variety is improved, but wireless communication performance uniformity deteriorates due to different permittivity values
Solution Approach 1:
A ceramic layer with controlled permittivity is introduced as an intermediary between the communication module and the housing. This ceramic layer acts as a mediator that compensates for permittivity variations caused by different colored housing materials, ensuring uniform wireless communication performance across all color variants while maintaining color variety in the housing.
Solution Approach 2:
The permittivity of the ceramic layer is specifically controlled and adjusted to compensate for the permittivity differences of various colored housing materials. By changing the permittivity parameter of the ceramic layer, the overall electrical characteristics are standardized, allowing different colored housings to maintain consistent wireless communication performance.
2Reliability
If different internal parts are tuned for each cover color, then wireless communication performance is optimized for each color, but manufacturing complexity and inventory management difficulty increase
Solution Approach 1:
The ceramic layer serves as a universal component that works with all colored housing variants without requiring separate tuning for each color. This single ceramic layer design replaces the need for multiple color-specific internal parts, simplifying inventory management while maintaining optimized wireless communication performance across all color variants.
Solution Approach 2:
By controlling the permittivity parameter of the ceramic layer, the system achieves standardized electrical characteristics that work universally across different housing colors, eliminating the need for color-specific part variations and simplifying manufacturing and inventory management.
3Temperature
If only heat diffusion sheets are attached inside ceramic cover parts, then thermal management is improved, but electrical performance control and color variety are limited
Solution Approach 1:
The ceramic layer's permittivity parameter is specifically controlled to achieve desired electrical characteristics. By adjusting this parameter, the system enables both effective thermal management and standardized electrical performance across different colored housings, while also allowing color variety in the housing materials.
Solution Approach 2:
The solution uses composite material architecture where a ceramic layer with specific properties is combined with the housing structure. This composite approach enables simultaneous achievement of thermal management, electrical performance control, and color variety that cannot be achieved with heat diffusion sheets alone.
