Solution Overview

Problem

Existing lighting equipment with gobos often struggles with blurry or unfocused patterns due to constraints in installation location, gobo position relative to the light source, and projection onto non-planar surfaces, making it difficult to reposition or repurpose lighting devices without significant recalibration.

Innovation Solution

A gobo apparatus featuring a housing with a collimated light source and interchangeable heads with gobos oriented non-perpendicularly to the light source plane, allowing for easy projection of focused patterns without the need for precise axial alignment or perpendicular orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a gobo is placed in the gate at the point of focus between the light source and lenses, then a pattern with crisp sharp edges can be projected, but the installation location and gobo position constraints make refocusing arduous or impossible

Engineering Contradiction:

Improvepattern focus sharpnessVSAvoidrefocusing ease

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent implements a dynamically adjustable gobo position mechanism that allows the gobo to be moved along the optical axis and angled relative to the light source. This dynamic positioning capability enables the system to maintain crisp pattern edges while adapting to different installation locations and projection surfaces, resolving the contradiction between focus sharpness and ease of refocusing.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the gobo's positional parameters (axial distance from light source and angular orientation) to optimize pattern focus for different installation scenarios. By adjusting these parameters, the patent achieves sharp pattern edges without requiring arduous recalibration, effectively resolving the contradiction between measurement precision and operational ease.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If the gobo position and orientation are precisely constrained to achieve focused patterns, then sharp edges are obtained, but repositioning or repurposing the lighting device requires significant recalibration time

Engineering Contradiction:

Improvepattern focus precisionVSAvoidrecalibration time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent employs a dynamically adjustable mounting mechanism that allows the gobo to be quickly repositioned and reoriented without requiring significant recalibration. This dynamic system maintains precise pattern focus while enabling rapid adaptation to different installation locations and projection surfaces, thereby reducing recalibration time loss.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The lighting device is designed with universal adjustability, allowing the same apparatus to achieve focused patterns in multiple installation configurations. The gobo's adjustable position and angle capabilities enable the system to function effectively across various scenarios without requiring dedicated calibration for each setup, reducing time loss during repurposing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If the gobo is oriented perpendicular to the light source plane, then alignment is simplified, but the system cannot adapt to non-planar or angled projection surfaces

Engineering Contradiction:

Improvegobo alignment simplicityVSAvoidsurface type adaptability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent introduces asymmetric positioning capabilities that allow the gobo to be oriented at non-perpendicular angles relative to the light source plane. This asymmetric configuration enables the system to adapt to angled and non-planar projection surfaces while maintaining precise pattern focus, resolving the contradiction between alignment simplicity and surface adaptability.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The system implements dynamic angular adjustment of the gobo orientation, transitioning from fixed perpendicular alignment to variable angular positioning. This dynamic capability allows the gobo to be optimally oriented for different projection surfaces, including angled and non-planar surfaces, while maintaining ease of alignment through controlled adjustment mechanisms.

Inventive Principle:

Principle #15Dynamics
