Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If MIMO antenna modules are configured on a single plane of a printed circuit board, then the device complexity is reduced, but the adaptability to receive beam forming signals from multiple directions deteriorates
Solution Approach 1:
The antenna system is divided into multiple independent MIMO antenna modules that can be independently adjusted. Each module can be individually positioned and oriented to face different directions, allowing the system to receive beam forming signals from multiple directions simultaneously without requiring complex rotation mechanisms for the entire board.
Solution Approach 2:
The patent introduces adjustable and rotatable mounting structures for each MIMO antenna module, enabling dynamic repositioning of individual antenna modules. This allows the antenna system to adapt its configuration based on the directionality requirements of beam forming signals, improving versatility while maintaining manageable complexity through modular design.
2Productivity
If the entire printed circuit board is rotated to align with beam forming signal direction, then the signal transmission rate is improved, but the ease of operation deteriorates due to inability to independently adjust antenna modules
Solution Approach 1:
By segmenting the antenna system into independent modules with individual adjustment capabilities, the patent enables selective optimization of specific antenna modules without affecting others. This segmentation allows operators to independently adjust each module's orientation to maximize signal reception from different directions, improving both transmission rate and operational flexibility.
Solution Approach 2:
The dynamic adjustment mechanism allows each MIMO antenna module to be independently rotated and positioned. This dynamic capability enables real-time optimization of antenna orientation to match beam forming signal directions, achieving high transmission rates while maintaining operational ease through independent module control rather than rigid board-level rotation.
3Adaptability or versatility
If multiple MIMO antenna modules are independently adjustable, then the adaptability to receive signals from multiple directions is improved, but the device complexity increases
Solution Approach 1:
The patent employs modular MIMO antenna units that can be independently configured and adjusted. Each module is self-contained with its own mounting and adjustment mechanisms, allowing independent optimization without requiring complex integrated control systems. This segmentation achieves multi-directional signal reception capability while managing complexity through standardized modular components.
Solution Approach 2:
The patent designs universal mounting structures and adjustment mechanisms that can be applied to multiple MIMO antenna modules using the same configuration principles. This universality reduces overall system complexity by repeating proven modular designs rather than creating unique complex configurations for each antenna, enabling multi-directional reception through standardized multi-functional components.
