Solution Overview

Problem

Existing systems for setting light environments in buildings require labor-intensive manual adjustments by users, who must visually check and adjust illumination settings to achieve desired lighting scenes.

Innovation Solution

A setting system that includes a setting input section, image data generator, and control data generator, which allows for the input of facility operation settings, rendering of light environments based on three-dimensional building data, and generation of control data to automate lighting and shading adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual visual adjustment of illumination lamp brightness is used to set lighting scenes, then the light environment can be customized, but the setting process becomes labor intensive and time consuming

Engineering Contradiction:

Improvelight environment customizationVSAvoidsetting time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent uses image generation to create a visual copy or representation of the lighting scene before actual implementation. The image generation unit generates an image showing the illumination lamp and its lighting effect based on setting data, allowing users to preview and confirm the lighting scene virtually before actual deployment, thus eliminating the need for repeated manual adjustments and on-site visual checking

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system performs preliminary actions by generating control data and visualizing the lighting scene before actual installation or adjustment. The control data generation unit creates control data based on the setting data and model data, and the image generation unit visualizes the expected lighting effect in advance, allowing users to confirm settings before actual implementation, thereby reducing on-site adjustment time

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If manual on-site adjustment of illumination lamps is performed to achieve desired lighting scenes, then accurate lighting effects can be realized, but the process requires physical presence and manual labor

Engineering Contradiction:

Improvelighting effect accuracyVSAvoidsetting operation ease

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The system creates a visual copy of the lighting scene through image generation, allowing users to review and confirm the lighting effect virtually. The image generation unit produces an image that represents the illumination lamp and its lighting effect, enabling accurate verification of lighting effects without requiring physical on-site adjustment

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces an intermediary mechanism - the image generation unit and control data generation unit - that mediates between the setting data input and the actual lighting implementation. This intermediary system processes the setting data, generates appropriate control data, and visualizes the expected lighting effect, thereby eliminating the need for manual on-site adjustment while maintaining lighting effect accuracy

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If traditional scene control switching devices are used, then lighting scenes can be switched, but the setting process requires repeated on-site adjustments and visual checks

Engineering Contradiction:

Improvelighting scene switchingVSAvoidsetting process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses image generation to create a virtual representation of the lighting scene, allowing users to preview and confirm settings remotely. The image generation unit generates an image based on model data and setting data, providing a visual copy of the expected lighting effect, thereby simplifying the setting process by eliminating repeated on-site adjustments and visual checks

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system performs preliminary visualization and control data generation before actual lighting implementation. The control data generation unit creates control data based on setting data and model data, and the image generation unit visualizes the lighting effect in advance, allowing users to confirm settings before deployment, thereby reducing the complexity of the setting process

Inventive Principle:

Principle #10Preliminary action
