Dual-Sided Window Display Replacing Vehicle Side Mirrors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side view mirrors on vehicles create wind drag, reduce fuel efficiency, and do not provide full visibility of the exterior environment, leading to blind spots for drivers.
Innovation Solution
A dual-sided transparent display system is integrated into vehicle windows, featuring a camera and processor that displays exterior visual information on the exterior side and interior visual information on the interior side, replacing traditional side view mirrors and enhancing driver visibility while communicating warnings to adjacent entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional side view mirrors are used, then drivers can see the exterior environment, but wind drag increases and fuel efficiency decreases
Solution Approach 1:
The patent removes traditional side view mirrors from the vehicle and extracts their viewing function, replacing it with a camera-based visual information display system integrated into the window. This eliminates the physical mirror structure that causes wind drag while preserving the essential function of observing the exterior environment.
Solution Approach 2:
The patent replaces the mechanical mirror system with an optical-electronic system consisting of cameras, processors, and display elements integrated into the window. This substitution eliminates moving parts and physical mirror surfaces that create aerodynamic resistance, reducing wind drag and improving fuel efficiency.
2Loss of information
If traditional side view mirrors are used, then drivers can see the exterior environment, but blind spots remain that reduce full visibility
Solution Approach 1:
The patent integrates multiple cameras positioned at different locations (front, rear, sides) to capture a comprehensive view of the exterior environment. The system processes and displays visual information from multiple angles simultaneously, providing drivers with a complete 360-degree view that eliminates blind spots while maintaining the function of observing the exterior environment.
Solution Approach 2:
The patent transitions from the limited two-dimensional view provided by traditional mirrors to a multi-dimensional visual information system. By integrating cameras at multiple positions and displaying processed visual data across the window surface, the system creates a comprehensive spatial representation of the exterior environment that eliminates blind spots and provides full visibility from all angles.
3Object-affected harmful factors
If a dual-sided transparent display is integrated into the window, then aerodynamics improve and visibility enhances, but device complexity increases
Solution Approach 1:
The patent merges the display function with the window structure itself, integrating cameras, processors, and display elements directly into the window assembly. This consolidation eliminates the need for separate mirror housings and mounting structures, reducing overall system complexity while maintaining aerodynamic benefits and enhanced visibility functionality.
Solution Approach 2:
The window assembly is designed to perform multiple functions simultaneously: it serves as the vehicle's structural window, an aerodynamic surface, and an integrated display system for visual information. The dual-sided transparent display allows the window to provide both exterior visibility and interior information display, reducing the need for separate components and simplifying the overall system architecture.

AI summary
A vehicle can include a window. The window can include an interior side and an exterior side. The vehicle can include a camera operatively positioned to capture visual data of a portion of an exterior environment of the vehicle. The vehicle can include a dual-sided transparent display forming at least a portion of the window. The vehicle can include a processor operatively connected to the camera and the dual-sided transparent display. The processor can be configured to selectively cause the dual-sided transparent display to display exterior visual information on the exterior side. The processor can be configured to cause the dual-sided transparent display to display interior visual information on the interior side. The interior visual information can include the visual data of the portion of the exterior environment of the vehicle.
