Vehicle Meter Panel Ring-Shaped Display with Layered Light Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for vehicles, such as combination meters, lack a new form of display beyond merely indicating a predetermined zone, particularly in representing critical engine speed ranges, which can lead to a lack of visual emphasis and differentiation.
Innovation Solution
A display device with a translucent meter panel featuring a ring-shaped decorative part and a predetermined zone, utilizing a first light shielding layer, a delustered layer, a smoke layer, and a second light shielding layer, where the light source illuminates the predetermined zone differently based on the ignition switch state, creating a new form of visual emphasis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a belt-like red zone is used to display the predetermined zone, then the rotation speed range exceeding the upper-limit rotation speed can be displayed, but the display lacks visual emphasis and differentiation
Solution Approach 1:
The display is segmented into multiple functional layers: a first light-shielding layer with a first opening, a delustered layer with a second opening, a smoke layer, and a second light-shielding layer. Each layer serves a specific function in creating the visual effect, allowing the predetermined zone to be highlighted through the coordinated interaction of these segmented components rather than a single belt-like structure
Solution Approach 2:
The invention transitions from a two-dimensional belt-like display to a multi-layered three-dimensional structure. By stacking multiple layers with different openings and material properties, the display creates depth and visual emphasis through the interaction of light with each layer, transforming a flat indication into a立体 visual experience that enhances differentiation
2Ease of manufacture
If multiple layers with different openings are used to create visual emphasis, then the predetermined zone can be highlighted, but the device structure becomes more complex
Solution Approach 1:
Multiple layers with different functions are merged into a single integrated display structure. The first light-shielding layer, delustered layer, smoke layer, and second light-shielding layer are combined in sequence, where each layer contributes a specific visual property. This merging allows the complex visual effect to be achieved through a unified structure rather than separate components, simplifying the overall device architecture while maintaining the desired visual emphasis
3Shape
If the decorative part and predetermined zone are viewed as a ring shape when ignition is off, then the display provides a unified appearance, but the predetermined zone lacks differentiation when ignition is on
Solution Approach 1:
The display dynamically changes its visual characteristics based on the ignition state. When the ignition is off, the decorative part and predetermined zone appear as a unified ring shape. When the ignition is on, the light source activates and causes the predetermined zone to be illuminated and viewed as wider than the decorative part, creating automatic differentiation without requiring manual intervention or complex control mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The display device effectively highlights the predetermined zone when the ignition is on, providing a wider appearance compared to the decorative part, enhancing visual emphasis and differentiation, thus offering a new form of display beyond mere zone indication.
Implementation Method 1
When an ignition switch of a vehicle is off, an external light entering toward a front side of the meter panel is reflected on the smoke layer and the second light shielding layer
Implementation Method 2
When the ignition switch of the vehicle is on and the light source lights, the light of the predetermined color emitted by the light source penetrates the second opening and a portion of the delustered layer corresponding to the first opening
Data Source
AI summary
In a display device, when an ignition switch of a vehicle is off, an external light entering toward a front side of a meter panel is reflected on a smoke layer and a second light shielding layer, and a decorative part and a predetermined zone are, as a whole, viewed through a second opening as being in a ring shape with a width of the second opening and of a color tone based on the smoke layer and the second light shielding layer. When the ignition switch of the vehicle is on, the predetermined zone is illuminated in a predetermined color by a light emitted by a light source with a width of the first opening to be viewed as being wider than the decorative part.
