Battery Pack Substrate Layout for Wireless Interference Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Providing multiple antennas on an electronic substrate to mitigate radio wave interference in battery packs complicates assembly and increases costs, leading to degradation in communication quality.
Innovation Solution
An electronic substrate unit with a single wireless module attached to one of two distinct attachment portions on the substrate, allowing selection of an installation position that avoids null points in the radio wave intensity, thereby reducing interference without additional antennas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are provided on the electronic substrate to reduce radio wave interference, then communication quality is improved, but device complexity and assembly complexity increase
Solution Approach 1:
The patent makes the attachment portion configurable through software control rather than fixing the antenna position physically. The control unit selectively activates different attachment portions based on communication conditions, enabling dynamic adaptation to reduce interference without adding multiple physical antennas.
Solution Approach 2:
The patent changes the operational state of the attachment portion from a fixed physical configuration to a dynamically controllable parameter. By controlling which attachment portion is active through software, the system can adapt to different communication environments and reduce radio wave interference without increasing hardware complexity.
2Reliability
If multiple wireless modules are provided on the electronic substrate to reduce radio wave interference, then communication quality is improved, but manufacturing cost increases
Solution Approach 1:
The patent makes a single wireless module serve multiple functions by enabling it to operate from different attachment portions. The same wireless module can be selectively activated at different locations on the electronic substrate depending on communication conditions, eliminating the need for multiple dedicated wireless modules.
Solution Approach 2:
The patent changes the operational configuration of the wireless module from a fixed single-location operation to a multi-location capable operation. Through software control, the same wireless module can be activated at different attachment portions, providing the benefits of multiple modules without the associated cost.
3Reliability
If multiple wireless modules are provided on the electronic substrate to reduce radio wave interference, then communication quality is improved, but assembly complexity increases
Solution Approach 1:
The patent introduces dynamic control of the wireless module's operational location through software. Instead of requiring multiple physically installed modules, the system dynamically selects which attachment portion to use based on communication conditions, simplifying the assembly process while maintaining communication quality.
Solution Approach 2:
The patent enables a single wireless module to function effectively at multiple attachment portions through software control. This multi-functionality eliminates the need for assembling multiple wireless modules, reducing assembly complexity while still providing the ability to mitigate radio wave interference.
