Vehicle Display Dial with Light-Reflecting Decorative Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses for vehicles cannot dynamically adjust the size of the display area while varying the appearance of decorative elements, limiting their adaptability to different display modes.
Innovation Solution
A display apparatus with a dial, analog meters, decorative parts, and a controller that uses a surface-treated layer with both light-transmitting and light-reflecting properties to adjust the visibility of the decorative parts based on the display area, allowing the size of the display area to be switched and the appearance of the decorative parts to be varied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display area size is switched by cropping the meter frame, then the display flexibility is improved, but the appearance variety of the decorative part is insufficient
Solution Approach 1:
The decorative part incorporates a surface-treated layer with light-reflecting properties that can change appearance characteristics. When the display area is switched, the controller simultaneously changes the display content and adjusts the visual appearance of the decorative part through the light-reflecting surface treatment, providing both display flexibility and appearance variety without requiring physical reconfiguration.
2Area of stationary object
If the meter frame is cropped in the circumferential direction, then the display area can be adjusted, but the decorative part appearance remains limited to color switching
Solution Approach 1:
The decorative part is designed with a surface-treated layer that provides light-reflecting properties in specific areas. This local quality enhancement allows different portions of the decorative part to exhibit different visual characteristics depending on the display mode, enabling more diverse appearance variations beyond simple color switching while maintaining the cropped meter frame configuration.
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
Enables dynamic switching of the display area size and appearance of decorative elements, enhancing the display's adaptability and user experience by controlling the visibility of the decorative parts through light-transmitting and light-reflecting properties.
Implementation Method 1
The decorative part includes a body member that has a light-transmitting property, and a surface-treated layer that is arranged on a surface of the body member, and has both of a light-transmitting property and a light-reflecting property. The decorative part is visually recognized entirely due to the light-reflecting property of the surface-treated layer when the image is displayed in the non-overlapping area.
Implementation Method 2
The image on the display is visually recognized in an overlapping part of the decorative part overlapping with the outermost area due to the light-transmitting property of the surface-treated layer when the image is displayed in the outermost area.

AI summary
A display apparatus includes: a dial having a first surface, a second surface and an opening; a meter; a decorative part at a peripheral part of the meter; a display at a second surface side and displaying an image; and a controller controlling an image display state. An outermost area of the display overlaps with a part of the meter. The decorative part includes: a body member having a light-transmitting property; and a surface-treated layer having a light-transmitting property and a light-reflecting property. The controller switches the state of image display in the outermost area and a non-overlapping area. The decorative part is visually recognized due to the light-reflecting property of the surface-treated layer when the image is in the non-overlapping area. The image is visually recognized in an overlapping part of the decorative part due to the light-transmitting property when the image is in the outermost area.
