Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional antenna designs are used, then antenna performance is maintained, but antenna size cannot be reduced sufficiently for mobile devices
Solution Approach 1:
The antenna is divided into multiple independent conductor patterns (first, second, third, and fourth antenna portions) disposed on different sides of the dielectric material block. Each conductor pattern can be independently designed and optimized, allowing the overall antenna system to achieve high performance while maintaining a compact form factor suitable for mobile devices.
Solution Approach 2:
The antenna design transitions from traditional planar configurations to a three-dimensional structure by disposing conductor patterns on multiple sides (first side, second side, third side, and fourth side) of the dielectric material block. This spatial distribution in multiple dimensions enables compact integration while maintaining effective radiation performance.
2Volume of moving object
If antenna size is reduced for mobile devices, then device integration is improved, but transmission efficiency and radiation performance deteriorate
Solution Approach 1:
The antenna system is segmented into multiple independent conductor patterns that can be individually optimized for specific frequency bands and transmission requirements. This segmentation allows each portion to contribute effectively to overall transmission efficiency despite the compact total size.
Solution Approach 2:
The dielectric material block with multiple conductor patterns serves multiple functions simultaneously: it provides structural support, electrical insulation, and hosts multiple antenna elements for different frequency bands and transmission modes, thereby maintaining high transmission efficiency in a compact form.
3Adaptability or versatility
If multiple antenna elements are integrated for 5G performance, then communication capability is enhanced, but device complexity increases
Solution Approach 1:
Multiple antenna elements are merged into a single integrated structure where all conductor patterns are disposed on one dielectric material block. This unified design reduces overall structural complexity compared to separate antenna assemblies while maintaining enhanced 5G communication capabilities through support for multiple frequency bands and MIMO configurations.
Solution Approach 2:
The dielectric material block serves as a universal platform that hosts multiple conductor patterns for different antenna functions (first, second, third, and fourth antenna portions), enabling diverse 5G communication capabilities including beamforming and MIMO without requiring separate structural assemblies for each function.
