Solution Overview

Problem

Conventional lamps often require multiple fixtures to provide different lighting functions, leading to increased space usage and complexity in installation, especially in vehicles where multiple lamps are needed for various functions like back-up, stop/tail/turn, and warning lights.

Innovation Solution

A combination lamp design that integrates multiple lighting functions, such as stop/turn/tail, back-up, and warning lights, into a single unit with separate power connections and LED light sources, allowing for independent activation of each function and reducing the overall space required.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate lamps are used to provide different lighting functions (back-up, stop/tail/turn, warning), then each function can be independently activated, but the total space required increases and installation complexity increases

Engineering Contradiction:

Improvelighting function integrationVSAvoidspace required

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines multiple separate lighting functions (back-up lamp, stop/tail/turn lamp, and warning lamp) into a single integrated combination lamp assembly. The flange-mounted back-up lamp is positioned adjacent to the stop/tail/turn lamp, and the warning lamp is integrated into the same assembly, allowing all functions to occupy a single mounting space on the vehicle rather than requiring separate mounting locations for each lamp.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The combination lamp assembly serves multiple lighting functions simultaneously within a single unit. The flange acts as both a mounting structure and a carrier for back-up lamp LEDs, while the central lamp housing contains stop/tail/turn functionality. The warning lamp can be activated independently or in combination with other functions, providing universal lighting coverage for various vehicle operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate lamps are used to provide different lighting functions, then each function can be independently activated, but the installation complexity increases

Engineering Contradiction:

Improvelighting function integrationVSAvoidinstallation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The combination lamp assembly is divided into distinct functional segments: the flange portion containing back-up lamp LEDs, the central lamp housing containing stop/tail/turn LEDs, and the integrated warning lamp portion. Each segment has its own LED array and control circuitry, allowing independent activation and maintenance of specific functions while maintaining a unified physical structure.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If multiple separate lamps are used to provide different lighting functions, then each function can be independently activated, but the total amount of space taken up increases

Engineering Contradiction:

Improvelighting function integrationVSAvoidspace occupied

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The combination lamp assembly employs a nested configuration where the flange-mounted back-up lamp is positioned within the same overall footprint as the stop/tail/turn lamp. The flange extends outward from the central lamp housing, allowing the back-up lamp LEDs to be mounted on the flange surface rather than requiring a separate mounting location. This nested arrangement minimizes the total volume occupied while maintaining all required lighting functions.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

Various embodiments of a combination lamp are provided, which combine a plurality of different lamp functions in a unitary configuration, and can reduce the total amount of space taken up for at least substantially the same amount of illumination produced. The combination lamps can be configured for use on vehicles, light fixtures, free standing lamps, decorative articles, etc. In some embodiments, each lamp component may have a power connection element independent from the other lamp components.
