Compact Multi-Pin Connector for Vehicle Rear View Camera Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear view camera systems require a time-consuming and costly process to replace a faulty camera, and the large diameter connector makes it difficult to connect the vehicle rear view mirror to the camera assembly, as they typically only support video signals and lack a power connection.
Innovation Solution
A compact connector system with a 5 mm diameter that combines power and video lines, allowing easy installation and replacement of the camera by routing the cable through the vehicle body, using a metal bracket to secure the camera near the license plate and incorporating a voltage reducer for stable power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large diameter connector (12 mm RCA connector) is used to connect video signals, then the video signal transmission is reliable, but the connector size makes it difficult to route the cable through the vehicle body and increases installation complexity
Solution Approach 1:
The patent combines power transmission and video signal transmission into a single integrated connector with multiple pins. This merging eliminates the need for separate power and video cables, reducing the overall cable diameter and simplifying routing through the vehicle body while maintaining reliable connections for both functions.
Solution Approach 2:
The connector is designed to perform multiple functions simultaneously: transmitting power, transmitting video signals, and providing ground connections. This multi-functionality replaces the need for separate connectors for each function, reducing installation complexity and cable routing difficulty.
2Reliability
If a separate power connection and video connection are used, then the power supply and video signal transmission are reliable, but the installation process becomes time-consuming and costly
Solution Approach 1:
The patent merges power connections and video signal connections into a single integrated connector assembly. This allows both power and video signals to be transmitted through one cable and connector, enabling camera replacement without exchanging entire wire harnesses and significantly reducing installation and replacement time.
Solution Approach 2:
The system is segmented into modular components: a camera module that can be independently replaced, and an integrated connector that combines power and video functions. This segmentation allows faulty cameras to be quickly swapped without affecting the wiring infrastructure.
3Stability of the object's composition
If an RCA connector with separate power and video connections is used, then the signal transmission is stable, but the connector diameter is large and requires extensive wiring modifications
Solution Approach 1:
The patent combines multiple wiring functions (power, ground, video signals) into a single integrated connector with multiple pins. This reduces wiring complexity by eliminating the need for separate power and video cables while maintaining stable signal transmission through the multi-pin connection design.
Solution Approach 2:
The connector transitions from a single-function large-diameter connector to a multi-function compact multi-pin connector. This dimensional change in connectivity (from single cable to multi-conductor bundled connector) reduces overall system complexity while maintaining transmission stability.

AI summary
A cable including a connector for connecting a vehicle rearview mirror monitor or a vehicle dashboard monitor to a camera connected to the rear of the vehicle. The cable has a smaller diameter than those currently available and includes wires for controlling a number of vehicle functions. A single cable wire provides both power and video signals to the monitor.
