1Reliability
If a conductive member (coaxial cable) is used to electrically couple multiple PCBs for wireless communication, then signal transmission capability is improved, but connecting issues between connectors may occur making detection difficult
Solution Approach 1:
The patent applies preliminary action by incorporating a detection circuit that proactively checks connector connections before wireless communication operations begin. The detection circuit includes a processor and memory that continuously monitor connection status, enabling early detection of connecting issues between the conductive member and PCBs, thus preventing communication failures.
Solution Approach 2:
The patent uses an intermediary approach by introducing a detection circuit as a mediator between the conductive member connectors and the PCBs. This detection circuit includes test signal generation units and detection units that indirectly monitor connection status without interfering with the main signal transmission path, enabling non-intrusive connection detection.
2Adaptability or versatility
If connectors are disposed on conductive members to enable electrical coupling, then signal transmission is enabled, but connecting issues such as misalignment or wrong terminal coupling may occur
Solution Approach 1:
The patent implements feedback by using the detection circuit to continuously monitor connector connection status and provide feedback signals to the processor. When a connecting issue is detected (such as misalignment or wrong terminal coupling), the system receives notification and can take corrective actions or alert the user, ensuring reliable connection status awareness.
Solution Approach 2:
The patent applies self-service by enabling the system to automatically detect and identify connecting issues without external intervention. The detection circuit autonomously performs connection verification, and the processor automatically processes detection results, allowing the system to self-diagnose connection problems between connectors.
