Solution Overview

Problem

Existing motor vehicle lighting systems, particularly for large vehicles like trucks and tractors, inadequately illuminate areas around the vehicle during reversing and precision driving, especially in low-light conditions, limiting visibility and increasing the risk of collisions with obstructing objects.

Innovation Solution

A light device for motor vehicles that combines a colored side marking light with a white visibility light, where the white light emitting part is activated with the brake lights, providing improved illumination around the vehicle and integrating both functions into a single unit to enhance visibility and reduce mounting and infrastructure costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate light devices are used for side marking and visibility illumination, then each function can be optimized independently, but the device complexity, mounting space, and infrastructure requirements increase

Engineering Contradiction:
Improvefunctional optimizationVSAvoidnumber of light devices
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines side marking light function and visibility illumination function into a single integrated light device. The housing contains both a side marking light (e.g., amber or red LED) and a visibility light (white LED), eliminating the need for separate light devices and reducing mounting complexity while maintaining functional optimization through coordinated operation of both light types

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated light device performs multiple functions simultaneously: it provides side marking to indicate vehicle presence and position, and provides visibility illumination to illuminate areas around the vehicle during reversing or precision driving operations. This multi-functional design reduces the overall number of components and infrastructure requirements

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

2Illumination intensity

If multiple separate light devices are mounted on the vehicle, then comprehensive coverage is achieved, but the mounting space and infrastructure requirements increase

Engineering Contradiction:
Improvevisibility coverageVSAvoidmounting space
Core Design Contradiction:
Illumination intensityVSArea of stationary object

Solution Approach 1:

The patent integrates side marking and visibility functions into one physical housing unit, reducing the total mounting footprint on the vehicle while maintaining comprehensive illumination coverage through the coordinated operation of both the side marking light and the white visibility light within the same device

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If separate light devices are used for side marking and visibility, then each function can be independently controlled, but the manufacturing and infrastructure costs increase

Engineering Contradiction:
Improveindependent controlVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent combines side marking and visibility functions into a single manufactured unit, reducing manufacturing complexity and infrastructure requirements such as wiring harnesses and control systems. The integrated design allows for simplified production and installation while maintaining the ability to control each light function independently through the vehicle's existing control systems

Inventive Principle:
Principle #5Merging (Combining)
