A wireless communication module is designed with multiple modules disposed on a substrate, eliminating the need for RF shielded coaxial cables and using a compact structure with antennas positioned near the edges, connected via series-to-deseries connectors, and enhanced with grounding connectors for improved isolation and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RF shielded coaxial cables are used to connect antennas to processing units, then signal transmission reliability is improved, but manufacturing cost increases and device complexity increases
Solution Approach 1:
The patent extracts and eliminates the RF shielded coaxial cables from the system by integrating the antenna elements directly onto the substrate adjacent to the wireless communication modules, thereby removing the need for separate cable connections while maintaining signal transmission reliability through direct coupling
Solution Approach 2:
The patent merges the antenna elements with the substrate structure, combining previously separate components (antennas, substrate, processing units) into an integrated layout where antenna elements are formed directly on the substrate adjacent to the wireless communication modules, eliminating intermediate connection components
2Volume of moving object
If multiple wireless communication modules are integrated in a compact space, then device miniaturization is achieved, but interference between modules increases
Solution Approach 1:
The patent applies local quality by positioning antenna elements at specific locations adjacent to their corresponding wireless communication modules on the substrate, creating localized signal paths that minimize interference while enabling compact integration of multiple modules in close proximity
Solution Approach 2:
The patent utilizes the substrate plane dimensionally by arranging antenna elements and wireless communication modules in a two-dimensional layout on the same substrate, allowing multiple modules to be integrated compactly while maintaining adequate spacing to reduce interference through strategic positioning
3Reliability
If isolated coaxial cables and antenna connectors are used, then signal isolation is improved, but the number of parts increases and manufacturing becomes complicated
Solution Approach 1:
The patent merges the antenna elements, substrate, and wireless communication modules into an integrated structure where antenna elements are formed directly on the substrate, eliminating the need for separate coaxial cables, connectors, and isolation components, thereby reducing the total number of parts while maintaining signal isolation through direct coupling
Solution Approach 2:
The patent extracts and removes the isolated coaxial cables and antenna connectors from the system, replacing them with direct substrate-based antenna elements that eliminate intermediate connection components and simplify the overall structure
