Camera-Based Mirrorless Vehicle Display System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles rely on mirrors for rear and side views, which are prone to damage and add weight and cost, necessitating a mirror-less display system for viewing vehicle surroundings.
Innovation Solution
A display system incorporating rear and side view cameras that project images onto the windshield and windows, using smart glass or head-up displays to show the driver external vehicle images without the need for mirrors, with control via a processor and sensors to manage image visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional mirrors are used for rear and side views, then the driver can see external images, but the vehicle weight and cost increase
Solution Approach 1:
The patent replaces mechanical mirror systems with electronic camera systems and display screens. Cameras mounted on the vehicle capture rear and side images, which are then displayed on electronic screens positioned within the vehicle interior, eliminating the need for physical mirrors and reducing weight.
Solution Approach 2:
The patent creates electronic copies of external images captured by cameras. These copied images are displayed on screens to provide the driver with visual information about rear and side conditions, replacing the direct optical reflection provided by mirrors.
2Reliability
If conventional mirrors are used for rear and side views, then the driver can see external images, but the mirrors are susceptible to damage
Solution Approach 1:
The patent replaces fragile mechanical mirror assemblies with robust camera systems housed in protective mounts and electronic display screens. The camera systems are positioned to capture images without protruding vulnerable elements, and the electronic displays are integrated into the vehicle structure for protection.
3Ease of manufacture
If mirrors are installed on vehicle sides, then rear and side views are available, but parts and cost increase
Solution Approach 1:
The patent extracts the viewing function from physical mirror assemblies and consolidates it into integrated camera-display systems. This extraction eliminates the need for separate mirror components, mounting hardware, and associated assembly operations, thereby reducing manufacturing complexity and cost.
Solution Approach 2:
The patent implements multi-functional camera systems that can capture images for multiple purposes: rear view monitoring, side view monitoring, and potentially other vehicle surveillance functions. This universality reduces the total number of components needed compared to dedicated mirror systems for each viewing angle.

AI summary
A display system for a vehicle includes a rear view camera constructed and arranged to obtain images external to the vehicle and associated with a rear of the vehicle. At least one side view camera is constructed and arranged to obtain images external to the vehicle and associated with a side of the vehicle. A display is constructed and arranged to display the images to a driver of the vehicle so that the driver can see what is occurring at the rear and the side of the vehicle without using mirrors.
