Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If standard mechanical toggle switches are replaced by advanced load control devices, then energy savings and advanced control features are achieved, but electrical rewiring and professional installation are required

Engineering Contradiction:
Improveadvanced control featuresVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent introduces a remote control device as an intermediary component that interfaces with the existing mechanical toggle switch through its actuator. This mediator enables advanced load control features without requiring replacement of the original switch, thus avoiding complex electrical rewiring while still providing energy savings and control capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The remote control device is designed to work with standard mechanical toggle switches while providing multiple control functions including dimming, fading, and programmable operations. This multi-functional approach allows the system to deliver advanced control features through a universal interface that兼容 existing switch infrastructure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If mechanical toggle switches are replaced with load control devices, then power delivery control is improved, but electrical wiring must be accessed and modified

Engineering Contradiction:
Improvepower control capabilityVSAvoidelectrical wiring complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The remote control device serves as a mediator between the user and the electrical load, intercepting and modifying the control signal from the mechanical toggle switch. It couples to the switch actuator and provides intelligent power control capabilities without requiring access to or modification of the electrical wiring infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the purely mechanical toggle switch operation with an electronically enhanced control system. The remote control device incorporates electronic circuits for signal processing, memory storage for programming, and microprocessors for intelligent control algorithms, substituting mechanical functionality with electronic systems while maintaining compatibility with the mechanical actuator interface.

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

3Adaptability or versatility

If existing mechanical switches are removed and replaced, then advanced control features are achieved, but professional electrical contractor assistance is required

Engineering Contradiction:
Improvecontrol functionalityVSAvoidinstallation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The remote control device acts as an intermediary that bridges existing mechanical switch infrastructure with modern control capabilities. By coupling to the mechanical actuator rather than replacing the entire switch assembly, it enables consumers to install advanced control features themselves without requiring professional electrical contractor assistance.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The device is designed for self-service installation by consumers. It includes user-friendly programming capabilities, intuitive controls, and a design that interfaces with existing switches without requiring electrical wiring knowledge or skills. The system enables end-users to independently configure and install advanced control features in their homes.

Inventive Principle:
Principle #25Self-service

AI summary

A remote control device may be configured to be mounted over the toggle actuator of a light switch and to control a load control device via wireless communication. The remote control device may include a base portion and a rotating portion supported by the base portion so as to be rotatable about the base portion. The remote control device may include a control circuit and a wireless communication circuit. The control circuit may be operably coupled to the rotating portion and to the wireless communication circuit. The control circuit may be configured to translate a force applied to the rotating portion of the remote control device into a control signal and to cause the communication circuit to transmit the control signal to the load control device.
