If standard mechanical switches are replaced by advanced load control devices requiring electrical wiring, then load control functionality is improved, but installation complexity and cost increase

Engineering Contradiction:
Improveload control functionalityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a remote control device as an intermediary that communicates wirelessly with the load control system, eliminating the need for consumers to perform electrical wiring. The remote control serves as a mediator between the user and the electrical system, allowing control without direct electrical connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces mechanical electrical wiring and physical switch installation with wireless communication technology. The load control device communicates with the electrical load through wireless signals, substituting the mechanical/electrical installation process with a wireless communication-based control system.

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

2Adaptability or versatility

If remote control devices are mounted in various orientations, then installation flexibility is improved, but user input interpretation becomes ambiguous

Engineering Contradiction:
Improvemounting orientation flexibilityVSAvoidorientation information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements an orientation detection circuit within the remote control device that automatically detects and determines the device's mounting orientation without external assistance. The device serves itself by autonomously sensing its orientation and using this information to correctly interpret user inputs, eliminating the need for manual orientation configuration.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The orientation detection circuit provides feedback to the control circuit about the device's current orientation. This feedback mechanism allows the system to continuously monitor and adapt to the mounting orientation, ensuring correct interpretation of user inputs regardless of how the device is positioned.

Inventive Principle:
Principle #23Feedback
