Solution Overview

Problem

Users face difficulties in controlling multiple lighting devices with different capabilities, as not all devices can generate desired colors, leading to confusion about which device is suitable for a specific color effect, and existing interfaces do not adequately report device limitations.

Innovation Solution

A controller with a communication unit and user interface that renders graphical representations of lighting devices within a color spectrum, indicating their capabilities, allowing users to select and control devices suitable for the desired color, and switching to alternative spectra when necessary, thus providing a unified interface for multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a user interface allows selection of any color for any lighting device, then the user interface appears simple and versatile, but the user is misled when the selected lighting device cannot actually produce the desired color

Engineering Contradiction:
Improvecolor selection capabilityVSAvoidcolor rendering accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system provides visual feedback by displaying different graphical representations (first type indicating capability, second type indicating incapability) based on the compatibility between the selected lighting device and the desired color. This feedback mechanism prevents user confusion by clearly indicating whether a device can produce the selected color.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The graphical representation of the lighting device changes based on its color rendering capability for the selected color. The system uses visual differentiation (different graphical representations) to communicate device capabilities, making the compatibility information immediately apparent to the user.

Inventive Principle:
Principle #32Color changes

2Loss of information

If the user interface provides detailed information about each lighting device's color capabilities, then the user can make informed selections, but the user interface becomes complex and difficult to use

Engineering Contradiction:
Improvedevice capability informationVSAvoiduser interface simplicity
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

Instead of displaying extensive text or technical specifications about color rendering capabilities, the system uses visual graphical representations that change based on capability. This conveys essential information (whether the device can produce the selected color) in a simple, intuitive visual format rather than complex textual information.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The system provides just enough information (visual indication of capability or incapability) without overwhelming the user with excessive details. The graphical representation changes to provide the necessary information about color rendering capability without requiring the user to interpret complex technical data.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If the system allows control of multiple lighting devices with different capabilities through a single user interface, then the system is versatile and user-friendly, but the user may be confused about which device to select for a specific color effect

Engineering Contradiction:
Improvemulti-device control capabilityVSAvoiddevice selection clarity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

When a user selects a lighting device and a color, the system provides immediate visual feedback by displaying the appropriate graphical representation indicating whether the device can produce the desired color. This feedback mechanism guides the user to make appropriate device selections without confusion.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Instead of requiring the user to know the capabilities of each device beforehand, the system inverts the approach by having the device's capability status (first or second graphical representation) automatically indicate its suitability for the selected color. The device effectively communicates its own capability status to the user.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

A controller for controlling at least a first lighting device and a second lighting device, the controller comprising a communication unit for communicating with the first and second lighting device, a user interface for receiving user input, a display unit, and a processor for rendering, on the display unit, a graphical representation of a first color spectrum, a first type of graphical representation of the first lighting device in the first color spectrum at a first position in the user interface, a second type of graphical representation of the second lighting device in the first color spectrum at a second position in the user interface, wherein the first type of graphical representation is indicative for the first lighting device being arranged for generating light matching a color of the first color spectrum associated with the first position in the user interface, and the second type of graphical representation is indicative for the second lighting device not being arranged for generating light matching a color of the first color spectrum associated with the second position in the user interface. The processor is further arranged for controlling, upon receiving a first user input for controlling the first lighting device via the user interface, via the communication unit, the color of one or more of the first and second lighting device according to the first user input.
