Solution Overview

Problem

Existing vehicle lighting systems lack a clear and identifiable way to visually represent the battery charge status, often relying on continuous colors or lights that can be unclear.

Innovation Solution

A multi-function lighting apparatus that includes a first section for displaying a daytime running light or position light and a second section that displays a segmented light to indicate the charge status of a vehicle battery, using distinct colors and segmentation to prevent color bleeding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If continuous colors or lights are used to display battery charge status, then the lighting system can show charge level, but the visualization becomes unclear due to color bleeding

Engineering Contradiction:

Improveclarity of charge status visualizationVSAvoidsimplicity of lighting design

Core Design Contradiction:

Loss of informationVSEase of manufacture

Solution Approach 1:

The lighting apparatus is divided into multiple discrete segments, where each segment corresponds to a specific charge status level. This segmentation prevents color bleeding between different charge indicators and enables clear, distinct visualization of the battery charge status through discrete light segments rather than continuous gradients.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If a single lighting apparatus displays multiple functions (daytime running light and charge status), then device complexity is reduced, but functional interference or bleeding may occur

Engineering Contradiction:

Improvenumber of separate lighting systemsVSAvoidfunctional independence of lighting modes

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The lighting apparatus is segmented into distinct functional zones: one segment dedicated to daytime running lights and another segment for charge status indication. This spatial segmentation ensures that each function operates independently without interfering with the other, maintaining functional reliability while consolidating multiple lighting systems into a single apparatus.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different segments of the lighting apparatus are assigned different functional qualities: the first segment is optimized for daytime running light emission while the second segment is configured for charge status visualization. This local differentiation of functional properties within the unified apparatus prevents cross-interference and ensures reliable operation of each function.

Inventive Principle:

Principle #3Local quality
