Solution Overview

Problem

Existing vehicle interior components lack an integrated solution for providing a user interface with illumination effects, heating elements, and input/output options that enhance occupant comfort and interaction.

Innovation Solution

A vehicle interior component comprising a substrate, light guide, and light-transmissive cover that integrates a heating element and user interface, featuring a dynamic lighting effect, input devices, and a three-dimensional profile to conceal the heating element while providing a visual and surface effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a heating element is integrated into the vehicle interior component, then occupant comfort is improved, but the visibility and aesthetic appearance of the component is worsened due to the exposed heating element

Engineering Contradiction:
Improveoccupant comfortVSAvoidaesthetic appearance
Core Design Contradiction:
Object-affected harmful factorsVSShape

Solution Approach 1:

The heating element is extracted from the visible front surface and relocated to the rear side of the light-transmissive cover, where it is concealed by the illumination effect. This separates the heating function from the aesthetic presentation, allowing the heating wires to be hidden while still providing thermal comfort to occupants.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The illumination effect changes the visual appearance of the cover by emitting light that conceals the heating element. The dynamic lighting effect alters the perceived color and brightness of the component, making the heating wires invisible or aesthetically pleasing when illuminated.

Inventive Principle:
Principle #32Color changes

2Shape

If a light-transmissive cover with dynamic lighting effect is used, then the aesthetic appearance and user interface are improved, but the ability to conceal the heating element is worsened without additional design features

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidconcealment of heating element
Core Design Contradiction:
ShapeVSLoss of information

Solution Approach 1:

The heating element is positioned in a different spatial dimension (rear side of the cover) relative to the illumination source (front side). This dimensional separation allows the light to pass through the cover and conceal the heating wires from the front viewing angle while maintaining heating functionality.

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

Solution Approach 2:

The light-transmissive cover acts as an intermediary between the illumination source and the heating element. The cover transmits light while simultaneously serving as a backdrop that conceals the heating wires when illuminated, mediating between the aesthetic lighting function and the hidden heating function.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple functional layers (light guide, heating element, cover layers) are integrated, then the functionality and user interface are improved, but the device complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple functional components (light guide, heating element, cover layers) are merged into a single integrated assembly where the light-transmissive cover serves dual purposes as both a structural component and a concealing element for the heating wires. The illumination system and heating system are combined in one component structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The light-transmissive cover performs multiple functions simultaneously: it serves as a structural protective layer, a light transmission medium for illumination effects, and a concealing backdrop for the heating element. This multi-functionality reduces the need for separate components.

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