Solution Overview
Problem
Conventional snap-mounting type remote control switches only offer wired remote control functionality, limiting their application range and preventing wireless control capabilities.
Innovation Solution
Incorporation of a micro control unit (MCU), RF receiver, power supply control circuit, signal input circuit, and radio emitting circuit into the remote control switch, enabling both wired and wireless remote control operations by using a PC board with a micro control unit (MCU) to generate control signals and a RF receiver to manage power output through radio frequency signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only wired remote control functionality is provided, then the device structure remains simple, but the application range is limited
Solution Approach 1:
The remote control switch integrates both wired remote control and wireless remote control functions into a single device. The PC board with MCU handles both wired signals from the remote control cable and wireless RF signals, enabling the same power output control circuitry to serve multiple control methods, thus expanding application range without proportionally increasing complexity
Solution Approach 2:
The patent combines the wired remote control circuit and wireless remote control circuit into a unified control system. Both control methods converge at the PC board which processes both types of control signals through the same power output control circuitry, merging multiple functions into a single integrated device
2Adaptability or versatility
If wireless remote control is added to the existing wired system, then dual-function capability is achieved, but the device complexity increases
Solution Approach 1:
The patent replaces part of the wired mechanical control system with a wireless RF control system. The RF receiver and MCU provide wireless control capability while sharing the same power output control circuitry, reducing the need for separate independent control systems and minimizing the increase in overall device complexity
Solution Approach 2:
The PC board with integrated MCU serves multiple functions: processing wired control signals from the remote control cable, receiving wireless RF signals, and controlling the power output in both operational modes. This multi-functional design achieves dual-function capability while avoiding proportional increases in device complexity
