Solution Overview

Problem

Conventional large-scale irradiation systems are inefficient in implementing animation emission with a simple configuration, as they require complex setups to project changing light patterns.

Innovation Solution

An irradiation system comprising a first irradiator for a single light element and a second irradiator for multiple elements aligned away from the single element, with a controller to synchronize their emissions, allowing for animation emission with a simple configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large-scale irradiation system is used to project complicated light patterns, then the ability to emit complex images is improved, but the system complexity and size increase

Engineering Contradiction:

Improveability to emit complex light patternsVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the light pattern emission into two separate irradiation units: a first irradiator for a single light element and a second irradiator for multiple aligned light elements. This segmentation allows each unit to be simple in structure while collectively achieving complex animation emission capabilities through coordinated operation controlled by a controller

Inventive Principle:

Principle #1Segmentation

2Device complexity

If a simple configuration with two irradiation units is used, then the device complexity is reduced, but the ability to implement animation emission deteriorates

Engineering Contradiction:

Improvesystem simplicityVSAvoidanimation emission capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The controller is configured to control the second irradiator to start emission of the second light pattern after the first irradiator has started emission of the first light pattern. This preliminary timing arrangement creates the animation effect of continuously changing light patterns, demonstrating that animation capability can be achieved through temporal sequencing rather than complex hardware

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If conventional large-scale systems are used for animation emission, then complex light patterns can be projected, but the implementation efficiency and simplicity deteriorate

Engineering Contradiction:

Improvelight pattern projection capabilityVSAvoidimplementation efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent uses two separate irradiation units that each project simplified light patterns (a single element and multiple aligned elements) that are temporally coordinated to create the perception of a single complex animated pattern. This copying approach achieves complex animation effects through simpler individual components working in sequence

Inventive Principle:

Principle #26Copying
