Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless switches are powered by batteries, then wireless control function is achieved, but frequent battery replacement is required and environmental pollution increases

Engineering Contradiction:
Improvewireless control functionVSAvoidbattery replacement frequency
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The wireless switch generates its own power through a micro generator that converts mechanical energy from button pressing into electrical energy. This self-powered mechanism eliminates the need for external batteries and their frequent replacement, while maintaining full wireless control functionality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the chemical energy storage system (batteries) with a mechanical-to-electrical energy conversion system (micro generator). The mechanical pressing action on the button directly generates electrical power through electromagnetic induction, substituting the passive battery system with an active energy harvesting mechanism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Stability of the object's composition

If wireless switches are designed to be affixed on wall structure, then stable installation is achieved, but battery replacement requires detaching and disassembling the switch

Engineering Contradiction:
Improveinstallation stabilityVSAvoidmaintenance convenience
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The self-powered design with integrated energy harvesting means the switch requires no battery compartment or disassembly for maintenance. The power generation system is built into the switch structure itself, making the device truly maintenance-free while preserving stable wall installation.

Inventive Principle:
Principle #25Self-service

3Reliability

If conventional wall wiring is used for controlling switches, then reliable power supply is achieved, but complex installation process and material waste occur

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the wired electrical power delivery system with a mechanical energy harvesting system. The micro generator converts mechanical button pressing into electrical power, eliminating the need for wall wiring, electrical connections, and associated installation complexity while providing autonomous power supply.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts the power supply function from the wall infrastructure and relocates it to the switch itself through the integrated micro generator. This extraction eliminates the need for wall wiring and electrical outlets, making the switch completely independent of building electrical systems.

Inventive Principle:
Principle #2Taking out (Extraction)

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 including a magnet assembly and a coil assembly being 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 wireless control signals.
