Vehicle Cabin Display Positioning for Rear Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to improve the usability of vehicles equipped with camera monitoring systems (CMS) by optimizing the placement and design of image capturing and display units to enhance the driver's ability to view rearward areas without visual obstruction or discomfort.
Innovation Solution
The vehicle body structure incorporates image capturing apparatuses to capture left-rearward and right-rearward areas, with corresponding display units positioned higher than the steering wheel's center and lower than its upper end, and indicators placed below the display units to provide clear visibility and minimize obstruction, allowing drivers to easily view the rear areas without altering their line of sight significantly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display units are positioned to be easily visible to the driver, then visibility of rear areas is improved, but the display units may obstruct the driver's line of sight to the road ahead
Solution Approach 1:
The display units are positioned in the vertical dimension (height) rather than only in the horizontal plane. By placing displays at specific heights (lower than the upper end but higher than the center of the steering wheel), the patent utilizes the vertical space to provide rear area visibility without blocking the horizontal line of sight to the road ahead.
2Ease of operation
If display units are positioned higher for better visibility, then ease of viewing rear areas is improved, but the indicators may become harder to see
Solution Approach 1:
The patent separates the display units and indicators into distinct vertical zones. Display units are positioned at a higher vertical position for optimal viewing of rear areas, while indicators are placed at a lower vertical position to remain clearly visible. This segmentation allows both elements to fulfill their functions without compromising each other's visibility.
3Reliability
If multiple display units and indicators are added to provide comprehensive information, then driving assistance is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple display units (left-side and right-side) and indicators into a single integrated vehicle body structure. Rather than having separate, distributed components, the displays and indicators are merged into the forward structure, sharing common mounting locations and structural support, thereby reducing overall system complexity while maintaining comprehensive driving assistance functionality.
