Solution Overview
Problem
Existing vehicle information systems struggle to provide quick and flexible output of relevant journey data to drivers, often limiting the clarity and accessibility of information due to restricted display areas.
Innovation Solution
A vehicle information system with a detection unit and control unit that generates graphic data for a display with perspective three-dimensional display objects, allowing for different viewing angles and operating modes to optimize information output, including a 'small stage' and 'big stage' mode, where display objects are rotated and scaled to prioritize visibility and comprehension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the display area is expanded to show more information, then the quantity of information output is improved, but the clarity and ease of comprehension deteriorates due to crowding
Solution Approach 1:
The patent applies dimensionality change by transitioning from a two-dimensional display to a three-dimensional stereoscopic display. Multiple display objects are arranged in three-dimensional space with different depths, allowing information to be organized vertically and horizontally rather than just on a flat plane. This enables more information to be displayed without crowding, as objects at different depths can be perceived simultaneously without overlapping confusion.
Solution Approach 2:
The patent segments information into multiple display objects positioned at different locations and depths in the stereoscopic display. Each display object can be independently positioned in three-dimensional space, allowing critical information to be placed in prominent positions while less critical information is positioned elsewhere. This segmentation prevents information crowding by distributing content across multiple spatial zones.
2Productivity
If multiple pieces of information are displayed simultaneously, then the productivity of information output is improved, but the clarity of individual information elements deteriorates
Solution Approach 1:
By utilizing the third dimension (depth) in the display, the patent allows multiple information elements to be presented simultaneously at different depths. Foreground objects can display critical information with high clarity, while background objects provide additional context. This vertical layering in depth space enables high information output efficiency without compromising the readability of individual elements.
Solution Approach 2:
The patent applies local quality by allowing different display objects to have different visual characteristics optimized for their specific information type. Each display object can be independently styled, sized, and positioned according to the importance and nature of the information it conveys, ensuring optimal clarity for each element while maintaining overall information density.
3Ease of operation
If the display area is limited to maintain clarity, then the ease of comprehension is improved, but the quantity of information that can be displayed deteriorates
Solution Approach 1:
The stereoscopic display adds a depth dimension to the traditional two-dimensional display area. This effectively increases the available display space without requiring a larger physical display surface. Information can be arranged in multiple depth layers, allowing more content to be presented while maintaining adequate spacing and clarity on each layer.
Solution Approach 2:
The patent implements nesting by placing display objects at different depths within the stereoscopic space. Smaller or less critical information elements can be positioned in the background or nested within the spatial arrangement of more prominent foreground objects. This nested arrangement maximizes information capacity within the limited physical display area while preserving clarity through depth separation.
