Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of electronic modules is increased to achieve high functionality, then the communication capabilities across various frequency bands are improved, but the space for mounting the modules decreases
Solution Approach 1:
The patent combines multiple transmission parts (first transmission part and second transmission part) into a single integrated antenna structure on the display panel. This merging approach allows multiple frequency band transmissions to coexist in a compact space, resolving the contradiction between enhanced communication capabilities and limited mounting area.
Solution Approach 2:
The antenna structure is designed to perform multiple functions by supporting transmissions across various frequency bands simultaneously. The patch part with dual transmission parts can handle different communication standards and frequency ranges, making the single structure universal for diverse communication needs without requiring separate dedicated modules for each function.
2Volume of moving object
If the antenna structure is compacted to reduce mounting space, then the device thickness is reduced, but the antenna bandwidth decreases
Solution Approach 1:
The patent utilizes the vertical dimension by positioning transmission parts at different spaced locations relative to the patch part. The first transmission part and second transmission part are disposed at different positions along the thickness direction, creating three-dimensional spatial separation. This dimensional approach allows compact planar footprint while maintaining sufficient electrical separation to preserve bandwidth characteristics.
Solution Approach 2:
The antenna is segmented into distinct functional components: a patch part and multiple transmission parts (first and second transmission parts). Each segment serves specific frequency ranges, and their spatial separation through positioning at different distances from the patch part allows independent optimization of each segment's performance while maintaining overall compactness.
3Area of stationary object
If transmission parts are positioned closer to the patch part to save space, then the coupling space is reduced, but the isolation between frequency bands decreases
Solution Approach 1:
The patent resolves the space-isolation trade-off by transitioning to three-dimensional positioning. Transmission parts are arranged at different vertical distances from the patch part rather than only lateral separation. This vertical stacking in the thickness direction reduces the planar coupling space footprint while maintaining adequate electrical isolation through controlled spacing in the vertical dimension, thus preserving frequency band isolation.
Solution Approach 2:
The first and second transmission parts are positioned asymmetrically at different spaced distances from the patch part. This asymmetric arrangement allows optimization of coupling strength for different frequency bands while maintaining sufficient isolation. The unequal spacing creates different coupling characteristics that enhance frequency discrimination and maintain isolation despite reduced overall space.
