Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle rear-view systems are often costly and difficult to install, limiting their adoption due to the need for extensive wiring and complex installation processes, making them inaccessible to many vehicle owners without automotive skills.
Innovation Solution
A low-cost, easy-to-install vehicle backup viewing system that utilizes a wireless connection between a rear-facing camera and display, powered by the vehicle's reverse lamp power line, eliminating the need for complex wiring and allowing for simple installation by connecting the camera to the reverse lamp power line, which activates when the vehicle is in reverse gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a rear-facing camera system is installed in a vehicle, then the driver's visibility of the area behind the vehicle is improved, but the system cost and installation complexity increase
Solution Approach 1:
The patent replaces the traditional mechanical wiring system with a wireless communication system. The camera unit transmits video signals wirelessly to the display unit, eliminating the need for complex wiring through the vehicle's interior. This substitution of mechanical connections with wireless communication directly resolves the contradiction by maintaining visibility improvement while dramatically reducing installation complexity
Solution Approach 2:
The patent extracts the camera and display units as separate, independently mountable components that can be installed without integrating into the vehicle's existing wiring system. The camera unit is mounted on the rear exterior, the display unit on the interior dashboard, and they communicate wirelessly, allowing extraction from the complex wiring system and simplifying installation to basic mounting and wireless pairing
2Illumination intensity
If a rear-facing camera system is installed in a vehicle, then the driver's visibility of the area behind the vehicle is improved, but the system cost increases
Solution Approach 1:
The patent employs relatively inexpensive camera and display units that can be purchased as aftermarket accessories rather than integrated factory systems. The wireless communication components use standard, cost-effective technologies, making the overall system affordable for consumers and reducing the barrier to adoption
Solution Approach 2:
By replacing complex wiring infrastructure with wireless communication, the patent eliminates the need for expensive installation labor involving drilling, wire routing, and electrical connections. This substitution dramatically reduces both material and labor costs, making the system more manufacturable and accessible
3Reliability
If extensive wiring is used to connect camera and display units, then the system reliability is improved, but the ease of installation deteriorates
Solution Approach 1:
The patent replaces the mechanical wiring connection with wireless communication between the camera and display units. This eliminates the need for installers to route wires through the vehicle's interior, drill holes, and make electrical connections, transforming a complex installation process into a simple matter of mounting two independent units and establishing wireless communication
Solution Approach 2:
The patent divides the system into two independent, self-contained units: a camera unit with its own power and processing, and a display unit with its own power and processing. Each unit can be installed independently without requiring connection to the other through wiring, allowing simple separate installation while maintaining reliable wireless communication between them
Data Source
AI summary
A system for displaying an external view of a vehicle is provided. The system may comprise a video camera for capturing images external to the vehicle and a display for displaying the images for the vehicle operator. The camera is powered by electrically connecting it to the reverse lamp power line and is operable to continuously capture images when powered. The camera may be mounted in a license plate frame to further simplify installation. The camera may communicate with the display through a wireless connection. The receiver and display may be mounted in the field of view of the vehicle operator, such as on the dashboard of the vehicle.
