Solution Overview

Problem

Current lighting systems for professional and semi-professional applications lack flexibility in adjusting lighting parameters such as color, directionality, and brightness in synchronization with audio/video events, limiting creative and artistic usage, especially in environments like theaters, homes, and virtual reality settings.

Innovation Solution

A method and system that utilize a control device and server-based repository to manage lighting sequences through time-coded data sets, allowing users to calibrate and control lighting fixtures remotely, synchronizing lighting effects with audio/video events via a computer program product, enabling flexible and synchronized lighting adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If audio sensors are employed to detect audio characteristics and control lighting sources, then lighting can be automatically adjusted to match audio programs, but the possible light combinations and creative/artistic usage are limited

Engineering Contradiction:
Improveautomatic lighting controlVSAvoidlight combinations and creative usage
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The patent introduces a virtual reality device as an intermediary between the user and the lighting control system. This device provides a graphical user interface that enables users to manually select and customize lighting parameters, thereby overcoming the limitations of automatic audio-based control while still allowing automated modes when desired. The VR device acts as a mediator that bridges automated control and manual creativity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system dynamically switches between automated lighting control based on audio detection and manual control through the VR device interface. The control mode is not fixed but adapts based on user needs, allowing the system to be both automated when convenient and manually adjustable when creative flexibility is required.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If lighting parameters are fixed in current applications, then system complexity is reduced, but the ability to modify lighting features during shows or media playback is lost

Engineering Contradiction:
Improvesystem simplicityVSAvoidlighting parameter modification
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system pre-configures multiple lighting sequences with associated time code data sets that can be automatically executed. These pre-programmed sequences reduce the need for complex real-time control while still providing extensive lighting modification capabilities. Users can select from pre-defined sequences or customize them through the VR interface.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enables dynamic changes in lighting parameters including color temperature, intensity, and timing by associating different time code data sets with lighting sequences. The system can modify multiple lighting parameters simultaneously based on the selected sequence and time codes, providing extensive adaptability without requiring complex manual adjustment of each parameter individually.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If manual control of lighting is required for every adjustment, then creative control is maximized, but ease of operation and time consumption increase

Engineering Contradiction:
Improvecreative controlVSAvoidoperation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The lighting control system is segmented into multiple independent lighting sources, each with its own controllable parameters and sequences. This segmentation allows users to control individual lighting fixtures or groups through the VR device interface, making complex lighting designs more manageable and easier to operate than controlling a monolithic lighting system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses time code data sets as digital copies of lighting sequences that can be stored, retrieved, and executed automatically. These digital representations of lighting programs eliminate the need for manual real-time adjustment while preserving the creative intent of the original lighting design.

Inventive Principle:
Principle #26Copying

4Measurement precision

If lighting sequences are pre-programmed with time code data sets, then synchronization with audio/video events is improved, but device complexity increases

Engineering Contradiction:
Improvesynchronization accuracyVSAvoidcontrol system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical or manual synchronization methods with digital time code data sets that are automatically processed by the control system. The time codes provide precise temporal information that enables accurate synchronization with audio and video events without requiring complex mechanical coordination or manual timing adjustments.

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