Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fixing lightning conductors to console panel units increase device size and complicate manufacturing, and can interfere with wireless communication antennas, affecting their characteristics.
Innovation Solution
An electronic circuit board with an antenna pattern for wireless communication and an electrostatic removing member on the opposite surface, where the electrostatic removing member is used to discharge static electricity without increasing the device size and minimizing antenna performance degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate lightning conductor member is used to protect the touch panel, then the lightning protection function is achieved, but the device size increases and manufacturing becomes more complex
Solution Approach 1:
The patent merges the lightning protection function with the existing circuit board structure by incorporating an electrostatic removing member (ground pattern) directly into the circuit board. This eliminates the need for a separate lightning conductor member, thereby maintaining protection functionality while reducing device size and simplifying manufacturing.
Solution Approach 2:
The circuit board is designed to serve multiple functions: it provides wireless communication through the antenna pattern, structural support, and lightning protection through the integrated electrostatic removing member. This multi-functionality eliminates the need for separate dedicated lightning protection components.
2Reliability
If a separate lightning conductor member is used, then the touch panel is protected from static electricity, but the number of components and assembly steps increases
Solution Approach 1:
The electrostatic removing member is integrated directly into the circuit board as a ground pattern, combining the lightning protection function with the existing structural component. This reduces the total number of discrete components and eliminates separate assembly steps for installing a dedicated lightning conductor.
3Reliability
If the lightning conductor is arranged in the vicinity of the wireless communication antenna, then the touch panel is protected, but the antenna characteristics are affected and noise is generated
Solution Approach 1:
The patent utilizes the third dimension (depth/thickness of the circuit board) to separate the antenna pattern on one surface from the electrostatic removing member on the opposite surface. This spatial separation in the vertical dimension allows both functions to coexist without interfering with each other, preventing noise generation while maintaining protection functionality.
