Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display screen and antenna structure are manufactured separately, then the manufacturing process is simpler for each component, but the integration level is lower and the structure becomes more complex
Solution Approach 1:
The patent combines the display screen and antenna structure into a single integrated array substrate. The antenna structure is formed by patterning conductive layers within the display substrate itself, merging two previously separate components into one unified structure that reduces overall device complexity while maintaining ease of manufacture through existing display fabrication processes.
Solution Approach 2:
The array substrate serves dual functions: it acts as both the display screen substrate and the antenna structure support. The conductive layers in the display substrate are designed to function as antenna elements, allowing the same substrate to perform both display and electromagnetic wave transmission/reception functions simultaneously.
2Reliability
If the display screen and antenna structure are manufactured separately, then each component can be optimized independently, but the overall structure becomes more complex and interference occurs between display and electromagnetic wave transmission
Solution Approach 1:
By integrating the antenna structure within the display substrate, the patent eliminates the need for separate antenna components and their associated mounting structures. This merging reduces device complexity and potential interference points while improving reliability through a unified structure where the display and antenna work together without external connections.
3Adaptability or versatility
If the antenna structure is added as a separate component, then the antenna functionality is achieved, but the overall device thickness increases
Solution Approach 1:
The antenna structure is nested within the existing display substrate layers. The conductive layers that form part of the display structure are simultaneously patterned to create the antenna elements, effectively nesting the antenna functionality within the display component itself. This eliminates the need for additional external antenna structures and reduces overall device thickness.
4Adaptability or versatility
If separate antenna structures are used, then antenna functionality is achieved, but signal line length increases reducing signal-to-noise ratio
Solution Approach 1:
The antenna elements are formed using the same conductive layers that are already present in the display substrate structure. This merging eliminates the need for separate antenna traces and connection lines, significantly reducing signal line length and improving signal-to-noise ratio while maintaining full antenna adaptability for various communication functions.
