Rotary Lighting Control Interface for Intensity and Color Adjustment

Solution Overview

Problem

Traditional control devices for electrical loads require multiple devices to control different aspects of lighting, such as intensity and color, increasing cost, complexity, and lack user-friendly interfaces with feedback mechanisms.

Innovation Solution

A single control device with a rotating portion and actuation mechanism allows simultaneous control of intensity and color, featuring a base portion, actuation portion, and control circuit that generates signals for multiple characteristics, along with visual indicators for feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple traditional control devices are used to control different aspects of lighting (intensity, color), then each specific control function can be achieved, but the system cost and complexity increase

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple control functions (intensity control, color temperature control, and scene activation) into a single control device with a rotating mechanism. The rotating portion can be turned in different directions or at different speeds to control different parameters, eliminating the need for multiple separate control devices and reducing system complexity while maintaining full control capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control device is designed as a universal controller that can perform multiple functions: adjusting light intensity, changing color temperature, and activating preconfigured scenes. This multi-functional design allows a single device to replace what would traditionally require multiple specialized control devices, thereby reducing overall system complexity

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

2Adaptability or versatility

If multiple traditional control devices are used to control different aspects of lighting, then each specific control function can be achieved, but the setup cost increases

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By merging multiple control functions into a single device, the patent reduces the total number of components that need to be purchased, installed, and configured. This consolidation directly lowers setup costs while maintaining comprehensive control over lighting parameters

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If traditional control devices are used, then simple control functions can be achieved, but the user interface lacks feedback mechanisms

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The control device incorporates visual feedback mechanisms that provide real-time information to the user about the current lighting state and the effect of control actions. This feedback loop enhances the user experience by confirming that control inputs are being processed and displaying the current operational status, thereby reducing information loss

Inventive Principle:
Principle #23Feedback

AI summary

A load control device may be configured to control multiple characteristics of one or more electrical loads such as the intensity and color of a lighting load. The load control device may switch from controlling one characteristic of the electrical loads to controlling another characteristic of the electrical loads based on the position and/or orientation of one or more components of the load control device. Such a position and/or orientation may be manipulated by moving the one or more components relative to a base portion of the load control device. The load control device may be a wall-mounted device or a battery-powered remote control device.
