Vehicle Warning Display Switching for Larger Symbol Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle instrument panels, displaying multiple warnings in a limited area results in poor visibility due to the inability to display images in large sizes, as each warning area is defined separately, limiting the overall image size and clarity for the occupant.
Innovation Solution
A display system utilizing multiple display switching devices that switch and combine light irradiations from various light sources, employing a lens array and pixel areas to display symbols in non-overlapping partial areas, allowing for larger image display of individual warnings by combining images from multiple devices when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple warnings are displayed simultaneously in a limited area, then all warning information is provided to the occupant, but the image size becomes small resulting in poor visibility
Solution Approach 1:
The patent implements dynamic switching between displaying multiple warnings simultaneously and displaying individual warnings in sequence. The display control device changes the display mode based on the number of active warnings, transitioning from a multi-warning display state to a sequential display state when the number of warnings exceeds a threshold, thereby optimizing visibility while maintaining information completeness
Solution Approach 2:
The patent employs periodic sequential display of individual warnings, where each warning is displayed one after another in a predetermined sequence. This periodic action allows each warning to occupy the full display area temporarily, ensuring high visibility, while the cycle repeats to cover all active warnings, maintaining information delivery despite the limited display area
2Quantity of substance
If separate display areas are defined for each warning, then multiple warnings can be displayed, but the overall image size is limited reducing clarity
Solution Approach 1:
The display system dynamically adjusts the display area allocation. When displaying individual warnings in sequence, each warning is granted access to the entire display area, maximizing image size and clarity. The display control device manages this dynamic area allocation, ensuring that each warning receives full attention during its display turn, thereby achieving high manufacturing precision in terms of image clarity
3Area of stationary object
If the display area is limited, then the instrument panel design is compact, but the warning images cannot be displayed in large size resulting in poor visibility
Solution Approach 1:
The patent uses periodic sequential display to overcome the limited display area constraint. By displaying warnings one after another in a cycle, each warning can utilize the entire limited display area during its turn, effectively achieving large image display despite the small physical display area. This periodic utilization maximizes the visibility of each warning within the compact instrument panel design
Solution Approach 2:
The system dynamically controls which warning occupies the full display area at any given time. The display control device manages the temporal allocation of the limited display space, ensuring that during each time interval, the active warning receives the maximum possible display area, thereby achieving high visibility within the compact form factor
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
Enhances visibility of warnings by enabling larger symbol display when showing individual warnings, while maintaining clarity for multiple warnings displayed in partial areas, thus improving recognition in limited spaces.
Implementation Method 1
a lens array in which a plurality of lenses are arranged and a display part including a plurality of pixel areas arranged to include an area through which light formed by condensing each light emitted from the plurality of light sources with each of the lenses of the lens array passes
