Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal relay systems experience unnecessary power consumption when only one end of the signal relay circuit is connected, as the system continues to operate even when there is no active signal transmission, leading to increased energy usage.
Innovation Solution
A signal relay system incorporating a signal detector, repeater, input and output terminal circuits, and a switch controller that activates the signal relay only upon detection of a wakeup signal, switching to a short-circuit mode when no signal is detected to reduce impedance and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the signal relay circuit continues to operate when only one end is connected, then the system remains ready for signal transmission, but unnecessary power consumption occurs
Solution Approach 1:
The patent implements dynamic operation mode switching between sleep mode and signal transmission mode based on connection detection status. The system transitions from a static always-on state to a dynamic state that adapts to actual usage conditions, activating full signal relay functionality only when both ends are connected and deactivating it during single-end connection scenarios to eliminate unnecessary power consumption while maintaining rapid response capability through periodic detection
Solution Approach 2:
The system employs periodic connection detection through dummy terminal circuits that send detection signals at regular intervals. This periodic action allows the system to maintain readiness for signal transmission by continuously monitoring connection status without requiring constant full-power operation, thereby reducing power consumption while ensuring the system can quickly resume normal operation when connections are established
2Use of energy by moving object
If the signal relay circuit is deactivated to reduce power consumption, then energy usage decreases, but the system cannot detect connections or transmit signals
Solution Approach 1:
The patent segments the signal relay circuit into distinct functional modules: dummy terminal circuits for connection detection, main signal relay circuits for signal transmission, and control logic for mode switching. This segmentation allows the detection function to operate independently in a low-power state while the main signal relay remains deactivated, enabling connection monitoring without requiring full system activation and thus reducing overall power consumption while maintaining detection capability
Solution Approach 2:
The dummy terminal circuits serve as intermediary elements that enable connection detection without requiring full signal relay functionality. These intermediary circuits can operate in a simplified mode to detect connections and trigger the main signal relay system only when needed, acting as a bridge between the low-power state and full operational state to maintain adaptability while minimizing energy usage
