Adjustable Diffuser Lighting Control for Cinema

Solution Overview

Problem

The current lighting systems in the cinema, TV, and photographic industries require frequent manual adjustments of diffusers, which is time-consuming and inefficient, and users lack a straightforward method to predict the effect of these adjustments without extensive trial and error.

Innovation Solution

A lighting device with an adjustable diffuser and a user interface that displays a graphical representation of the output, allowing users to select and adjust diffusion settings easily, and a control unit that adjusts the diffuser properties based on calibration information and sensor measurements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual diffuser adjustments are performed, then lighting effects can be customized, but time consumption and effort increase significantly

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical adjustment of diffusers with an electronic control system. A processor receives input signals and automatically controls the diffuser properties through electronic actuation, eliminating the need for manual physical adjustment while maintaining full customization capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The lighting device performs self-adjustment through its integrated control system. The processor automatically modifies diffuser properties based on received signals without requiring external manual intervention, allowing the system to service itself in terms of configuration and setup.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If multiple different diffusers are used for different scenes, then lighting versatility is improved, but the complexity of managing and changing diffusers increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs a dynamically adjustable diffuser system where the diffuser properties can be changed electronically during operation. This dynamic control allows a single diffuser to perform the functions of multiple static diffusers by adjusting its optical characteristics through electronic signals, reducing the need to manage multiple physical diffuser components.

Inventive Principle:

Principle #15Dynamics

3Measurement precision

If trial and error methods are used to determine diffusion effects, then accurate lighting effects can be achieved, but time and effort for configuration increase

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system incorporates feedback mechanisms where the processor receives input signals that indicate desired lighting effects and automatically adjusts the diffuser properties accordingly. This closed-loop control eliminates the need for trial-and-error adjustment by directly translating user intentions into precise diffuser configurations through electronic feedback control.

Inventive Principle:

Principle #23Feedback
