Solution Overview

Problem

Current door handles in vehicles are long bar handles that make it difficult to integrate ambient light without adding space or weight to the vehicle.

Innovation Solution

A semi-circular shaped door handle with integrated ambient light, where the light is sandwiched between the handle structure and an inner handle structure, secured with a single attachment member, and aesthetically covered.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a long bar handle is used, then the handle structure is simple and easy to manufacture, but it is difficult to integrate ambient light and requires more space and weight

Engineering Contradiction:
Improvehandle structure simplicityVSAvoidspace required
Core Design Contradiction:
Ease of manufactureVSArea of stationary object

Solution Approach 1:

The patent applies curvature by transforming the traditional long bar handle into a semi-circular shaped handle. This curved design allows the ambient light to be integrated within the arcuate structure, specifically positioning the light along the curved path of the handle. The semi-circular configuration reduces the spatial footprint compared to a linear bar handle while providing sufficient space along the curve to accommodate the lighting elements, thus resolving the contradiction between manufacturing simplicity and space efficiency for light integration.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Ease of manufacture

If a long bar handle is used, then the handle structure is simple and easy to manufacture, but it adds weight to the vehicle when integrating ambient light

Engineering Contradiction:
Improvehandle structure simplicityVSAvoidvehicle weight
Core Design Contradiction:
Ease of manufactureVSWeight of stationary object

Solution Approach 1:

The patent merges the handle structure with the ambient light integration by designing the semi-circular handle where the light is positioned within the handle's own structure rather than as a separate additive component. The light is integrated along the curved path of the handle, utilizing the existing structural space. This merging approach allows the handle to serve dual purposes: providing the gripping function and housing the ambient light, thereby avoiding additional weight that would result from attaching a separate light assembly to a traditional bar handle.

Inventive Principle:
Principle #5Merging (Combining)

3Illumination intensity

If ambient light is integrated into a long bar handle, then illumination is provided, but additional space and weight are required

Engineering Contradiction:
Improveambient lightVSAvoidspace required
Core Design Contradiction:
Illumination intensityVSArea of stationary object

Solution Approach 1:

The patent transitions from a one-dimensional linear bar handle to a two-dimensional semi-circular handle. This dimensional change allows the ambient light to be positioned along the curved path, effectively distributing the illumination function throughout the arcuate structure. The light is integrated within the plane of the semi-circular handle rather than requiring additional three-dimensional space. This dimensional transformation enables the handle to provide comprehensive ambient illumination while maintaining a compact spatial footprint, as the light follows the curve of the handle rather than requiring separate mounting space.

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

AI summary

A door handle assembly for a vehicle has a handle structure with an arcuate side edge. A light is coupled with the handle structure. An inner handle structure is coupled with the handle structure sandwiching the light between the handle structure and the inner handle structure. A single attachment member secures the door handle assembly with the vehicle door.
