Solution Overview
Problem
Existing smart switches face issues with power supply limitations, particularly with single live wire systems causing weak current and flickering in low-power devices, and are susceptible to indoor illumination environments, while traditional battery solutions require frequent replacement and solar panels are inefficient indoors.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single live wire power supply is used, then device complexity is reduced, but power supply stability deteriorates causing weak current and flickering
Solution Approach 1:
The patent divides the power supply system into two independent parts: a first power supply component connected to the single live wire for basic operation, and a second power supply component (battery) for stable power delivery. This segmentation allows the system to maintain simplicity in wiring while achieving stability through the battery component that eliminates flickering and weak current issues.
2Reliability
If traditional battery solution is used, then power supply stability is improved, but maintenance requirements increase due to frequent battery replacement
Solution Approach 1:
The patent implements a self-charging mechanism where the first power supply component charges the second power supply component (battery) automatically during operation. This self-service approach eliminates the need for frequent manual battery replacement while maintaining stable power supply, as the battery recharges itself from the power it consumes or from the power supply loop.
3Use of energy by moving object
If solar panel is used for power supply, then energy independence is improved, but effectiveness deteriorates in indoor illumination environments
Solution Approach 1:
The patent uses the power supply loop (electrical wiring) as an intermediary energy source instead of relying on light. The first power supply component extracts energy from the power supply loop to charge the battery, which then provides stable power to the controlled device. This intermediary approach replaces the ineffective solar panel in indoor environments with a reliable electrical energy harvesting method from existing wiring.
4Adaptability or versatility
If wireless control function is added, then device functionality is improved, but power consumption increases
Solution Approach 1:
The patent makes the second power supply component (battery) serve multiple functions: it provides stable power to the control component for wireless control operations, and simultaneously stores energy for the switch component to operate. This multi-functionality reduces overall power consumption by efficiently utilizing the stored energy for both control and switching operations.
