Solution Overview

Problem

Existing vehicle light systems require multiple components and wires, increasing cost, weight, and complexity, while also making it difficult to add projectors to existing vehicles.

Innovation Solution

A light assembly that integrates a projector directly with a light bar, sharing power and control wires, and featuring a sealed light assembly with a customizable lens stack for projecting patterns or logos onto the ground.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a projector is added to an existing vehicle light system, then the vehicle gains light projection capability, but the number of parts and wires increases

Engineering Contradiction:

Improvelight projection capabilityVSAvoidnumber of parts and wires

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the projector and light bar into a single integrated assembly where the projector is mounted directly on the light bar housing. They share common power and control wires from the vehicle's existing wire harness, eliminating the need for separate wiring for the projector. This merging approach adds projection capability while minimizing increases in parts and wiring complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated assembly allows the light bar to serve multiple functions: both illumination and light projection. The shared power and control connections enable the system to perform both functions using the same electrical infrastructure, making the addition of projection capability more versatile without proportionally increasing system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a projector is added to an existing vehicle light system, then the vehicle gains light projection capability, but the cost increases

Engineering Contradiction:

Improvelight projection capabilityVSAvoidcost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By integrating the projector with the light bar and sharing power and control wires from the existing wire harness, the patent reduces the total number of components and wiring required. This consolidation lowers manufacturing costs compared to installing a standalone projector system with separate wiring and control circuits.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If multiple separate components are used for light projection, then the projector can be added to existing vehicles, but the weight increases

Engineering Contradiction:

Improveinstallability on existing vehiclesVSAvoidweight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent merges the projector with the light bar into a single assembly that can be installed on existing vehicles. By combining these functions in one unit with shared wiring, the total weight is reduced compared to installing separate projector and light bar systems with duplicate wiring and mounting hardware.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A light assembly having a projector integrally connected to a light bar. The projector and the light bar share power and control wires from a wire harness. The projector includes a projector aperture whereby light (oftentimes in a pattern or logo formation) passes therethrough and directs onto a ground surface. The projector includes a light assembly configured to hold the components for projection.
