Meter Structure With Peripheral Indicator Lighting for Clear Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing meter device structure, where engine RPM, direction display, and other information are arranged in the display part, leads to information overload, making it difficult to see the indicators, especially when displayed on a screen, resulting in potential loss of three-dimensional segments and confusion with other displays.
Innovation Solution
A meter structure with a light source for indicators positioned on the outer-peripheral side surface of the meter device, where the light is reflected on a wall body, allowing the indicators to be displayed outside the screen, reducing the display screen's dimensions and improving visibility, and using a support body that integrates the wall body to reduce components and enhance illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If indicators are arranged in the display part on the display screen, then various information can be displayed, but the amount of information becomes excessive and indicators become difficult to see
Solution Approach 1:
The patent divides the indicator display function into two separate locations: the display screen for general information and the outer peripheral side surface for indicators. This segmentation allows indicators to be visually separated from other information, improving their detectability while maintaining comprehensive information display capabilities.
Solution Approach 2:
The patent transitions indicator display from the two-dimensional display screen to the three-dimensional outer peripheral side surface of the meter device. This dimensional change creates physical separation and spatial distinction, making indicators more prominent and easier to detect without cluttering the display screen.
2Loss of information
If indicators are displayed on a display screen, then information can be conveyed, but three-dimensional segments are lost and confusion with other displays occurs
Solution Approach 1:
The patent segments the display system into distinct functional zones: the display screen for two-dimensional information and the outer peripheral side surface for three-dimensional indicator elements. This spatial segmentation preserves the three-dimensional characteristics of indicators while maintaining comprehensive information conveyance.
Solution Approach 2:
The outer peripheral side surface acts as an intermediary space between the display screen and the user, providing a dedicated area for indicators that maintains their three-dimensional visibility while coordinating with the overall display system.
3Area of stationary object
If the display screen dimension is reduced, then the meter device becomes more compact, but indicator visibility may be compromised
Solution Approach 1:
The patent extracts the indicator display function from the display screen and relocates it to the outer peripheral side surface. This extraction allows the display screen to be reduced in size while indicator visibility is maintained or improved through the dedicated external display area.
Solution Approach 2:
By moving indicators to the outer peripheral side surface, the patent utilizes the third dimension (depth/height) of the meter device structure. This allows the display screen to be minimized while indicators maintain prominence through their spatial positioning outside the screen plane.
