Solution Overview

Problem

Existing spotlights require a large space for secondary light sources in inter-lens spaces, leading to an unfavorable ratio between the surface area occupied by lenses and inter-lens spaces.

Innovation Solution

An optical assembly with a grille that fills part of the inter-lens spaces, using a second group of light sources to generate a secondary light effect, supported by a transparent grille and opaque support element that fix the lenses, allowing for a more efficient use of space and generation of both primary and secondary light effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If secondary light sources are placed in inter-lens spaces to generate diffuse light effects, then the spotlight can produce additional lighting effects, but the inter-lens spaces occupy a relatively large area in relation to the lenses

Engineering Contradiction:

Improvelighting effects capabilityVSAvoidinter-lens space area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines the grille structure (for secondary light sources) and the support element (for fixing lenses) into a single integrated component. This merging eliminates the need for separate structures, reduces the total space required, and allows secondary light sources to be placed in the inter-lens spaces without occupying excessive area, thereby resolving the contradiction between lighting effect versatility and space consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The grille structure serves multiple functions: it supports the secondary light sources for generating diffuse light effects, provides structural support for the lenses, and acts as a mounting framework. This multi-functionality reduces the need for additional dedicated components, thereby minimizing the space required while maintaining lighting effect versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Illumination intensity

If a large number of inter-lens spaces are present to accommodate secondary light sources, then diffuse light effects can be achieved, but the ratio of inter-lens space area to lens area becomes unfavorable

Engineering Contradiction:

Improvediffuse light effectVSAvoidinter-lens space area

Core Design Contradiction:

Illumination intensityVSArea of stationary object

Solution Approach 1:

The patent employs a thin grille structure that can accommodate secondary light sources while occupying minimal space. The grille acts as a flexible framework that provides the necessary support for generating diffuse light effects without requiring large inter-lens spaces, thus maintaining a favorable lens-to-inter-lens space area ratio.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of manufacture

If the grille and support element are made separate components, then assembly flexibility is improved, but the overall device complexity increases

Engineering Contradiction:

Improveassembly flexibilityVSAvoidcomponent quantity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the grille and support element into a single integrated component, reducing the total number of parts and simplifying the device structure. This integration maintains assembly flexibility while eliminating the complexity associated with coordinating multiple separate components, thereby resolving the contradiction between ease of manufacture and device complexity.

Inventive Principle:

Principle #5Merging (Combining)
