Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patient monitors with bi-directional diodes used for optical communication often remain powered on even when not docked or when the docking partner lacks a photo transceiver, leading to premature failure due to continuous power consumption.
Innovation Solution
A docking interface system that includes a magnetic field sensor and processor to detect docking events, enabling power to the bi-directional diode only when necessary, and disabling it when not required, using a rechargeable power supply and power distribution controller to manage power efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bi-directional diode is always powered on to ensure optical communication readiness, then communication reliability is improved, but the lifespan of the diode deteriorates due to continuous power consumption
Solution Approach 1:
The bi-directional diode's power state is made dynamic rather than static. The diode transitions between powered-on and powered-off states based on real-time docking detection. When a docking event is detected via magnetic field sensor, the diode is powered on for communication; when undocked, it is powered off to conserve lifespan, thus resolving the contradiction between reliability and lifespan.
Solution Approach 2:
The system uses the magnetic field sensor to automatically detect docking events and control the power state of the bi-directional diode without manual intervention. This self-service mechanism ensures the diode is only powered when needed, extending its lifespan while maintaining communication reliability during actual docking operations.
2Adaptability or versatility
If the bi-directional diode remains powered on during undocking or when the docking partner lacks a photo transceiver, then communication availability is maintained, but energy consumption increases leading to premature failure
Solution Approach 1:
The system implements feedback control by continuously monitoring magnetic field signals to detect docking status. Based on this feedback, the power management circuit dynamically adjusts the diode's power state. When docking is detected, power is supplied; when undocked or communication is not needed, power is cut off, thus reducing energy consumption while maintaining communication availability when actually required.
Solution Approach 2:
Instead of continuous powering, the bi-directional diode operates periodically based on docking events. The magnetic field sensor detects periodic docking/undocking cycles and triggers corresponding power on/off cycles. This periodic operation pattern reduces overall energy consumption while ensuring the diode is active during each docking period when communication is needed.
