Solution Overview

Problem

Existing light fixtures in the entertainment industry lack the ability to produce innovative and synchronized stage effects while maintaining ease of production and cost-effectiveness.

Innovation Solution

A light fixture with a support assembly allowing rotation about two orthogonal axes and a control device to adjust light source parameters based on the casing's position or movement, enabling synchronized color and intensity changes in the projected beam.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the light fixture includes specific devices to produce stage effects, then the stage effects become more diverse, but the size and cost of the light fixture increase

Engineering Contradiction:

Improvestage effects diversityVSAvoidlight fixture size and cost

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control device is configured to control the light source assembly based on position or movement signals from the support assembly, enabling the same hardware to produce multiple different stage effects through software control. This allows diverse stage effects without adding specific devices for each effect type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention changes the control parameters of the light source assembly (color, intensity) based on the position and movement of the casing. By dynamically adjusting these parameters according to movement signals, the system creates varied stage effects using the same physical components.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the light fixture produces synchronized color and movement effects, then the stage effects become more innovative, but the control system complexity increases

Engineering Contradiction:

Improvesynchronized stage effectsVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control device receives position and movement signals from the support assembly and uses this feedback to adjust the light source assembly parameters in real-time. This feedback mechanism enables synchronized color and movement effects without requiring complex pre-programming or additional sensors.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The light fixture uses its own movement signals (from the support assembly) to control the light source assembly, rather than requiring external control systems. The system serves itself by using its positional data to automatically adjust lighting parameters.

Inventive Principle:

Principle #25Self-service
