Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of electronic modules is increased to achieve high functionality, then the device performance is improved, but the available mounting space is reduced
Solution Approach 1:
The antenna module integrates multiple functional components (radiation elements, transmission parts, coupling structures) into a single unified structure that serves both antenna and structural functions, allowing multiple electronic functions to coexist in limited space
Solution Approach 2:
The antenna module utilizes three-dimensional spatial arrangement with radiation elements positioned at different heights and angles relative to the display panel, effectively using vertical and angular dimensions to maximize functionality within a constrained planar area
2Length of stationary object
If the antenna coupling space is reduced to meet thinning requirements, then the device thickness is decreased, but the antenna bandwidth is reduced
Solution Approach 1:
The transmission parts are designed with adjustable coupling distances and configurable geometries that allow the antenna system to dynamically adapt its electrical characteristics, maintaining broadband performance despite reduced physical coupling space
Solution Approach 2:
The antenna module employs variable geometric parameters in the transmission parts and radiation elements, including adjustable lengths, widths, and spacing, which can be optimized to achieve wide bandwidth operation within constrained thickness requirements
3Device complexity
If a single transmission part is used to simplify the structure, then the device complexity is reduced, but the frequency band coverage is limited
Solution Approach 1:
Each transmission part is designed to serve multiple frequency bands and support various radiation patterns, allowing the antenna module to achieve wide frequency coverage while maintaining a relatively simple dual-part structure
Solution Approach 2:
The antenna module divides the radiation structure into multiple independent radiation elements, each capable of operating at different frequency bands, while using a simplified two-part transmission structure to manage all elements
