Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems lack a user-friendly method to simultaneously display multiple video feeds from various imagers due to limited space on the instrument panel, preventing efficient utilization of all available image data.
Innovation Solution
A display system with an array of proximity sensors and a controller that allows users to select and control the display of multiple image feeds through hand gestures, enabling seamless switching and scaling of video content based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple video feeds are displayed simultaneously on the instrument panel, then the utilization of image data is improved, but the limited space on the instrument panel prevents efficient display of all available feeds
Solution Approach 1:
The patent moves the display from the two-dimensional instrument panel to the rearview mirror surface, effectively adding a new display dimension. This allows multiple video feeds to be displayed simultaneously without consuming instrument panel space, as the rearview mirror provides an additional display surface that does not compete for the same physical real estate.
Solution Approach 2:
The display system embeds the video feed displays within the rearview mirror assembly itself. The rearview mirror housing contains the display device, which can show multiple video feeds in various configurations (full display, picture-in-picture, side-by-side). This nesting approach allows the display functionality to be integrated into the existing mirror structure without requiring additional instrument panel space.
2Ease of operation
If a user interface is added to control display selections, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical or button-based user interfaces with gesture-based control. The gesture sensor detects hand movements in the field of view and translates them into display control commands. This substitution eliminates the need for physical buttons, knobs, or touchscreens on the mirror surface, reducing mechanical complexity while maintaining ease of operation through intuitive gestures.
Solution Approach 2:
The system automatically detects gestures within its field of view and responds by changing display configurations. The gesture sensor and controller work together to provide self-service control, where the display adapts to user intent through detected hand movements without requiring complex interface hardware. The system serves itself by using the existing imaging infrastructure to both capture video feeds and detect control gestures.
