Engineering Contradiction Analysis
1Reliability
If multiple circuit elements are integrated on a single substrate, then noise removal and signal conversion functions are achieved, but the installation surface area becomes large
Solution Approach 1:
The communicator is divided into multiple substrates, with the first substrate containing the first conductor and the second substrate containing the second conductor. This segmentation allows the installation surface area to be reduced while maintaining the noise removal function through distributed circuit element placement across separate substrates connected by a flexible substrate connector.

This segmentation allows the installation surface area to be reduced while maintaining the signal conversion function through distributed circuit element placement across separate substrates connected by a flexible substrate connector.
Solution Approach 2:
The patent transitions from a two-dimensional layout on a single substrate to a three-dimensional arrangement using multiple substrates connected in space. The flexible substrate connector enables vertical or spatial stacking, reducing the footprint on the installation surface while maintaining all necessary circuit functions.
3Area of stationary object
If substrates are separated to reduce installation area, then connection flexibility is improved, but signal integrity may be affected
Solution Approach 1:
A flexible substrate connector is used to connect the first substrate and the second substrate. This flexible connector maintains reliable electrical connection between the separated substrates while allowing for spatial arrangement that reduces the overall installation surface area, thus preserving signal integrity despite physical separation.

AI summary
A communicator (relay) receives a differential signal that is a voltage difference between two electrical signals that propagate through two respective conducting wires. The communicator removes noise from the two electrical signals using a first conductor as a reference potential. The communicator converts the differential signal that is the voltage difference between the two electrical signals with the noise removed into a voltage signal that is a voltage with the reference potential corresponding to a potential of a second conductor. The first conductor and the second conductor are respectively disposed on a first substrate and a second substrate. The first substrate and the second substrate are connected via a substrate connector with flexibility.
