Solution Overview

Problem

Existing lighting devices struggle to conform the illuminated area to the size and shape of various pieces of art, often resulting in inefficient light usage due to either under- or over-illumination, and the use of baffles to adjust size leads to blocked spill light.

Innovation Solution

A lighting device with adjustable light housings, baffles, and beam modifying devices that allow for independent adjustment of the illuminated area's height, width, position, and brightness, enabling precise conformation to the target object.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If baffles are used to trim down the size of the illuminated area, then the illuminated area size can be adjusted to conform with the target piece of art, but spill light is blocked which causes inefficiencies

Engineering Contradiction:

Improveilluminated area size adjustmentVSAvoidspill light blocking

Core Design Contradiction:

Manufacturing precisionVSLoss of energy

Solution Approach 1:

The patent employs a beam modifying device with adjustable elements that can dynamically change the beam angle and illuminated area size. The device includes a rotation mechanism that allows the beam modifying element to rotate between different positions, enabling continuous adjustment of the illuminated area dimensions without blocking spill light, thus resolving the contradiction between precise size adjustment and light efficiency

Inventive Principle:

2Device complexity

If a single projector style lighting device is used to illuminate art of different sizes, then device simplicity is maintained, but the illuminated area cannot conform to various target object sizes and shapes

Engineering Contradiction:

Improvelighting device structureVSAvoidilluminated area size conformity

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent incorporates a beam modifying device with adjustable components that allow the single lighting device to dynamically adapt its illuminated area size and shape. The rotation mechanism enables the beam modifying element to change the beam angle, allowing the same device to conform to various art piece dimensions while maintaining relatively simple overall structure

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the beam angle parameter through the rotation of the beam modifying element to adapt the illuminated area size. By adjusting the beam angle parameter, the lighting device can conform to different target object sizes without changing the fundamental device structure, thus achieving versatility while maintaining simplicity
