Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rearview mirrors in vehicles can be obstructed by loading boxes or cargo, leading to reduced visibility for drivers, which poses safety risks during driving.
Innovation Solution
A digital rear mirror system that includes a camera device to capture a rear view video and a processor to adjust the angle of view based on driving information such as speed, steering, and reversing status, ensuring an unobstructed view for the driver by dynamically adjusting the displayed image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional rear mirror is used, then the structure is simple and cost-effective, but the rear view is blocked by loading boxes or cargo
Solution Approach 1:
The patent replaces the conventional optical mirror system with an electronic imaging system. A rearview camera captures images that are processed by a controller to generate a synthesized rearview image displayed on a screen. This substitution eliminates the need for physical mirrors and resolves the blocking issue caused by loading boxes or cargo, while providing a reliable and unobstructed rear view.
Solution Approach 2:
The patent introduces a controller as an intermediary component that processes raw camera images and synthesizes a virtual rearview image. The controller acts as a mediator between the camera sensor and the display screen, manipulating the visual information to create an accurate representation of the rear scene, thereby ensuring reliable visibility regardless of physical obstructions.
2Adaptability or versatility
If the angle of view is fixed, then the device structure is simple, but the rear view cannot be adjusted according to driving conditions
Solution Approach 1:
The patent implements a dynamic angle of view adjustment mechanism where the controller modifies the field of view based on real-time driving conditions. When the vehicle is stationary or moving slowly, the system displays a wider angle to show more of the rear environment. When the vehicle is moving at higher speeds, the system narrows the angle of view to focus on the direct rear path, enhancing adaptability to different driving scenarios.
Solution Approach 2:
The patent changes the angular parameter of the displayed image based on driving conditions. The controller adjusts the angle of view parameter dynamically, expanding or contracting the visible field depending on factors such as vehicle speed, steering angle, and proximity to other vehicles. This parameter adjustment provides versatile adaptability without requiring multiple physical cameras or complex mechanical adjustments.
3Loss of information
If a wide angle of view is always displayed, then the driver can see more of the rear environment, but the relevant driving information may be less clear
Solution Approach 1:
The patent implements dynamic adjustment of the angle of view parameter based on driving conditions. When the vehicle is stationary or moving slowly, the system displays a wider angle to show more of the rear environment, reducing information loss. When the vehicle is moving at higher speeds or during critical maneuvers, the system narrows the angle of view to focus on the direct rear path, improving the clarity and precision of driving-relevant information.
Solution Approach 2:
The patent dynamically changes the angular parameter of the displayed image to optimize the balance between environmental awareness and driving information clarity. The controller adjusts the field of view parameter based on factors such as vehicle speed, acceleration, and steering angle, ensuring that the most relevant information is always presented with appropriate clarity while minimizing loss of useful environmental context.
