Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack functional diversity in device operations, primarily due to the simplicity of signal transmission through electro-optical composite cables, which only transmit direct current and data signals without enabling advanced device control or status switching.
Innovation Solution
Implementing alternating-current signals on the power supply cable of electro-optical composite cables to control device status switching, allowing for enriched device functionality by superimposing these signals with direct current without interference, and enabling feedback mechanisms for device status monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only direct current is transmitted through the power supply cable, then the transmission is simple and reliable, but device functionality remains simple and limited
Solution Approach 1:
The patent combines direct current (for power supply) and alternating current signals (for control and status indication) into a single power supply cable transmission system. The power supply cable simultaneously carries both the direct current for powering devices and the alternating current signals for controlling device status switching, thereby enriching device functionality without requiring separate control cables.
Solution Approach 2:
The power supply cable is transformed from a single-function power transmission medium into a multi-functional communication and control channel. It can transmit both power (direct current) and control information (alternating current signals), enabling the cable to serve multiple purposes: power supply, status indication, and device control, thus resolving the contradiction between functionality and complexity.
2Adaptability or versatility
If alternating-current signals are superimposed on the power supply cable with direct current, then device control functionality is enriched, but signal transmission complexity increases
Solution Approach 1:
The patent uses alternating current signals with specific frequencies (50Hz or 60Hz) superimposed on the direct current in the power supply cable. The periodic nature of the alternating current allows for clear distinction between power transmission and control signal transmission, enabling device control functionality while maintaining manageable signal transmission complexity through standard AC frequency conventions.
3Ease of operation
If the power supply cable transmits both direct current and alternating-current signals, then device status switching control is enabled, but the cable must handle multiple signal types simultaneously
Solution Approach 1:
The patent implements a feedback mechanism where alternating current signals are transmitted through the power supply cable to indicate device status (such as operational state, error conditions, or power levels). The receiving end detects these AC signal variations and provides feedback information, enabling bidirectional communication and simplified device status switching control without requiring complex separate communication infrastructure.
