Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wired connections are installed in completed walls, then remote switches or sensors can be connected to control systems, but the installation requires damaging the walls and additional repair costs

Engineering Contradiction:

ImproveInstallation easeVSAvoidWall damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces wired mechanical connections with wireless electromagnetic communication. The wireless transmitter uses a transducer element to convert mechanical energy from actuation into electrical energy, which is then used to transmit wireless signals, eliminating the need for physical wiring through walls.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless transmitter is energy-autonomous, harvesting mechanical energy directly from the actuation action itself through the transducer element. This self-powering mechanism eliminates the need for external power sources or batteries, allowing the device to be installed anywhere without wiring infrastructure.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If external power sources like batteries are used in wireless transmitters, then wireless signal transmission is enabled, but frequent maintenance and signal range reduction occur as batteries discharge

Engineering Contradiction:

ImproveWireless operationVSAvoidMaintenance frequency

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The transmitter harvests energy from the actuation action itself through the transducer element, making it self-powered. This eliminates batteries and external power sources, removing the need for maintenance related to power supply and eliminating signal degradation over time.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses periodic actuation to generate energy pulses. Each actuation event charges the energy storage element, enabling periodic wireless signal transmission without continuous power consumption or battery replacement.

Inventive Principle:

Principle #19Periodic action

3Ease of manufacture

If wired connections are prepared before walls are completed, then installation is straightforward, but additional time and effort are required during construction

Engineering Contradiction:

ImproveInstallation simplicityVSAvoidConstruction time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The patent eliminates the need for pre-installed wiring by using wireless transmission. The wireless transmitter can be installed on the surface of completed walls, allowing installation to occur after construction is complete, thereby eliminating the time-consuming process of fishing wires through walls during construction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If walls are made from non-penetrable materials or include barriers, then structural integrity and fire safety are improved, but installation of wired connections becomes impossible without damage

Engineering Contradiction:

ImproveWall integrityVSAvoidInstallation feasibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces physical wiring through walls with wireless electromagnetic signals. The wireless transmitter mounts on the surface of the wall and communicates wirelessly, eliminating the need to penetrate fire breaks, studs, windows, or other structural barriers, thereby maintaining wall integrity while enabling installation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
