Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless controllers use batteries as power source, then wireless control function is achieved, but operating cost increases and environmental pollution occurs due to frequent battery replacement
Solution Approach 1:
The wireless controller is equipped with a power generation device that converts kinetic energy from user operations (pressing, sliding, or knocking gestures) into electrical energy to charge the battery. This self-charging mechanism eliminates the need for external power outlets and frequent battery replacements, allowing the controller to power itself through normal usage
Solution Approach 2:
The power generation device utilizes periodic kinetic actions from user interactions with the controller. Each pressing, sliding, or knocking gesture generates electrical energy that is stored in the battery, converting intermittent user actions into continuous power supply capability
2Reliability
If wall controlling switch uses wiring configuration, then reliable electrical connection is achieved, but installation complexity increases and wall structure must be modified
Solution Approach 1:
The patent replaces the traditional mechanical wiring system with a wireless communication system. The wireless controller transmits control signals through wireless communication modules, eliminating the need for physical electrical connections between the switch and the lighting device, thus avoiding wall modifications and complex wiring installation
Solution Approach 2:
The wireless controller integrates multiple functions including power generation, wireless communication, and control signal transmission in a single device. This multi-functional design replaces the traditional separate combination of wall switches, wiring systems, and power sources
3Adaptability or versatility
If wireless switch is designed as portable device, then flexibility in placement is achieved, but ease of operation decreases due to difficulty in locating the switch
Solution Approach 1:
The patent merges the wireless controller with a power generation device and battery system into an integrated unit. This combination allows the controller to be placed in convenient locations without requiring access to power outlets, while the self-charging capability ensures continuous operation regardless of placement location
4Ease of operation
If wireless switch affixed on wall structure uses batteries, then wireless control function is achieved, but ease of repair worsens due to need to detach and disassemble for battery replacement
Solution Approach 1:
The integrated power generation device automatically charges the battery through kinetic energy from user operations, eliminating the need for manual battery replacement. This self-service charging mechanism removes the requirement to detach or disassemble the wireless switch for maintenance purposes

AI summary
A self-powered wireless switch includes at least one micro generator and a control panel for transmitting wireless control signals. The micro generator includes a magnet assembly and a coil assembly which are arranged to be moved relatively to one another to generate an induced current within the coil assembly; the coil assembly including an iron core and a wire winding around the outside of the iron core to form a magnetic coil; the magnet assembly including a permanent magnet and magnet conductive plates arranged at two sides of the opposite magnetic poles of the permanent magnet. The self-powered wireless switch enables the magnetic assembly and the coil assembly to move relatively to one another and converts the mechanical energy to electricity, thereby achieving self-power generation and providing electricity to the control panel for transmission of the wireless control signals.
