Solution Overview

Problem

Conventional vehicle light assemblies lack the ability to project three-dimensional visual effects, limiting customization and visual interest.

Innovation Solution

A backlit three-dimensional lamp design featuring a transparent lenticular sheet with a rendering of indicia, an outer lens, and a homogeneous light source positioned behind the sheet to create a floating 3D image projection outside the lamp assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional vehicle light assemblies use standard two-dimensional markings, then the structure is simple and easy to manufacture, but the visual effect is flat and lacks customization

Engineering Contradiction:
Improvevisual effect customizationVSAvoidlamp structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms conventional two-dimensional markings into three-dimensional visual effects by introducing a lenticular sheet with multiple focal points. This allows the marking to appear at different depths and positions depending on the viewing angle, creating a floating 3D image effect without significantly complicating the overall lamp structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The lenticular sheet acts as an intermediary element between the light source and the outer lens. It modulates the light to create the 3D effect, serving as a mediator that transforms standard lighting into customized visual displays while maintaining structural simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If a lenticular sheet with indicia rendering is added to create 3D projection, then visual interest and aesthetic appeal are enhanced, but the device complexity increases

Engineering Contradiction:
Improvevisual effect intensityVSAvoidnumber of components
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent combines the lenticular sheet with the indicia rendering in a single integrated component. The marking is directly formed on or integrated with the lenticular sheet, eliminating the need for separate marking elements and reducing the overall component count despite adding 3D functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lenticular sheet serves multiple functions: it acts as a light guide, a projection element, and a visual display medium. By making this single component multi-functional, the patent enhances visual effects without proportionally increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides a unique and customizable visual effect by projecting a 3D image that appears to hover and change perspective with viewer movement, enhancing the aesthetic appeal of vehicle light assemblies both at night and during the day.

Implementation Method 1

a light source positioned behind the transparent lenticular sheet to provide backlighting of the indicia rendering such that the lenticular sheet projects a forward image that hovers beyond the outer lens

AI summary

A backlit three-dimensional lamp for a vehicle includes an indicia rendering disposed on a transparent lenticular sheet, an outer lens positioned in front of the transparent lenticular sheet, and a light source positioned behind the transparent lenticular sheet. The light source provides backlighting of the indicia rendering such that the lenticular sheet projects a forward image that hovers beyond the outer lens. A vehicle light assembly includes a light source adapted to produce a substantially homogeneous light, a rendering of indicia located adjacent the light source and facing away from the light source such that the rendering of indicia is backlit by the light source, and an array of light-modifying elements aligned with the light source to at least partially cover the rendering of indicia for creating a projection of the rendering of indicia outside the vehicle light assembly.
