Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle dashboard displays, especially in low-cost vehicles, face high manufacturing costs due to expensive large-screen AVN systems, necessitating a cost-effective solution for enhanced information communication and manipulation.
Innovation Solution
A vehicle indoor illumination device integrating a light-emitting unit, diffuser, and controller into the dashboard, utilizing RGB LEDs and a diffuser to provide customizable lighting patterns, reducing the need for large screens by extending visual information and communication through the dashboard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a large-screen AVN display is installed to enhance information communication and manipulation, then the information display capability is improved, but the manufacturing cost increases significantly
Solution Approach 1:
The patent combines the display function and lighting function into a single integrated dashboard component. The light-emitting unit with diffuser and cover part serves both as an illumination source and as an information display medium, eliminating the need for separate large-screen AVN displays in low-cost vehicle configurations.
Solution Approach 2:
The illumination device performs multiple functions: it provides interior lighting, displays information through light patterns on the cover part, and communicates with occupants through customizable lighting sequences. This multi-functionality replaces what would traditionally require separate display and lighting systems.
2Loss of information
If a large-screen display is used to provide extended visual information to occupants, then the visual information capability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent merges the display function and lighting function into a single integrated dashboard component. The light-emitting unit with diffuser and cover part serves both as an illumination source and as an information display medium, eliminating the need for separate large-screen AVN displays in low-cost vehicle configurations.
3Ease of manufacture
If high-cost large-screen displays are replaced with lighting-based information communication, then the manufacturing cost is reduced, but the information display precision may be compromised
Solution Approach 1:
The patent applies different optical properties to different regions of the cover part through pattern portions with varying light scattering characteristics. This allows specific areas to display different information or emphasize different visual elements, enabling precise information communication despite the simplified technology.
Solution Approach 2:
The system uses RGB LED light-emitting elements that can change color and emit different wavelengths of light. By controlling the color and intensity of light in different pattern portions, the system can convey different types of information and maintain high information display precision.

Function Achieved in This Case
This solution enhances marketability, usability, and reduces manufacturing costs by providing a modular, cost-effective means to communicate information and extend display areas beyond traditional screens, improving the occupant experience while minimizing high-cost components.
Implementation Method 1
a light-emitting unit disposed on the housing to emit light
Implementation Method 2
a diffuser disposed outside the light-emitting unit in a manner as to close the upper opening of the housing to allow the light emitted from the light-emitting unit to diffuse to the outside
Implementation Method 3
a cover part disposed on an outer surface of the diffuser and on which a light pattern is formed through scattering of the light transmitted through the diffuser
