Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reference potentials of relay boards are connected via wiring lines through control board, then circuits can be electrically connected, but impedance becomes high and reference potentials cannot be kept at same potential against electrical noise
Solution Approach 1:
The patent introduces a conductive base as an intermediary component to connect reference potentials of multiple relay boards. This conductive base serves as a mediator that provides a low-impedance path for potential equalization, effectively shielding the circuits from electrical noise while maintaining reliable electrical connections across all relay boards.
Solution Approach 2:
The patent implements equipotentiality by connecting all relay board reference potentials to the conductive base, which is maintained at a constant potential. This ensures that all reference potentials across different relay boards are kept at the same potential level, eliminating potential differences that would otherwise allow electrical noise to interfere with signal integrity.
2Length of stationary object
If relay boards are mounted with high-density to reduce device thickness, then device thickness is reduced, but electrical noise interference increases
Solution Approach 1:
The conductive base acts as an intermediary shielding structure that protects high-density mounted relay boards from electrical noise. By positioning the conductive base to cover the relay boards while maintaining electrical connection to reference potentials, it provides noise shielding without increasing device thickness, allowing compact high-density mounting while suppressing electrical interference.
