Vehicle Camera Wiring Routing Through Door-Fender Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle camera installations result in scattered wire harnesses inside the vehicle door, requiring disassembly of the vehicle door for wiring, leading to prolonged installation times and potential damage to door buckles and vibration noise.
Innovation Solution
A vehicle-use camera system featuring a housing, camera body, wire rod, and fixing device, where the wire rod passes through a gap between the vehicle door and front fender, with fixing devices controlling its direction, allowing for ordered installation without disassembling the door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If wire harnesses are arranged inside a rubber pipe connected with the vehicle door and vehicle body, then the wiring is protected and organized, but the vehicle door needs to be disassembled for installation, requiring time and causing buckles to be easily broken
Solution Approach 1:
The patent extracts the wire rod from the rubber pipe arrangement and creates a separate fixing mechanism using fixing devices that attach directly to the vehicle door structure. This eliminates the need to disassemble the door for wiring installation while still providing organized and protected routing of the wire rod through the gap between the vehicle door and front fender.
Solution Approach 2:
The patent introduces fixing devices as intermediary components that bridge the wire rod and the vehicle door structure. These fixing devices provide a stable mounting solution without requiring door disassembly, thus resolving the contradiction between wiring organization and installation ease.
2Ease of manufacture
If wire harnesses are scattered inside the vehicle door, then installation is simple, but the wire harnesses are apt to be entangled or crushed by the vehicle door during opening and closing
Solution Approach 1:
The patent applies preliminary action by pre-positioning the wire rod along a predetermined path through the gap between the vehicle door and front fender using fixing devices. This preliminary arrangement prevents the wire harnesses from being scattered or entangled during door operation, while still maintaining installation simplicity.
Solution Approach 2:
The patent replaces the scattered mechanical arrangement of wire harnesses inside the door with a structured routing system that guides the wire rod through a dedicated path outside the door, eliminating entanglement and crushing issues while keeping the installation process simple.
3Stability of the object's composition
If the entire vehicle door is disassembled to arrange wire harnesses, then the wiring can be properly organized, but the installation time increases and buckles are easily damaged
Solution Approach 1:
The patent extracts the wiring organization task from the door disassembly process by creating a separate fixing system that attaches to the door structure without requiring full disassembly. This allows proper wiring organization to be achieved while significantly reducing installation time.
Solution Approach 2:
The fixing devices are designed to be pre-installed or easily attached to the vehicle door structure, allowing the wire rod to be routed and organized without the time-consuming process of complete door disassembly and reassembly.
4Stability of the object's composition
If fixing devices are used to control wire rod direction, then the wire rod is securely fixed and aesthetically pleasing, but the device complexity increases
Solution Approach 1:
The fixing devices are designed as simple, inexpensive components that can be easily installed and removed. Their simplicity offsets the added complexity by making the overall system easier to maintain and replace if needed, while still achieving secure wire rod fixation.
Solution Approach 2:
The fixing devices are segmented into multiple simple attachment points along the wire rod path, each providing localized support and direction control. This segmentation achieves secure fixation while keeping each individual fixing device simple in design.

AI summary
A vehicle-use camera, and an automobile are provided, relating to the technical field of automobile parts and equipment. The vehicle-use camera includes a housing (100), a camera body (200), a wire rod (300), a wiring portion (400) and fixing devices (500). The wire rod (300) can be fixed by the wiring portion (400), the wiring portion (400) is connected with the side edge of the vehicle body by a fixing section (401), a wiring section (402) is configured to run through a gap between a vehicle door (600) and a front fender (700), bringing the wire rod (300) to pass through the gap between the vehicle door (600) and the front fender (700) to protrude into the vehicle, thus the vehicle door (700) does not need to be disassembled, the wire rod (300) can be arranged inside the vehicle in an ordered and attached way by the plurality of fixing devices (500), the direction in which the wire rod (300) runs is controlled, alleviating the technical problems existing in the prior art that the wiring harnesses are scattered inside the vehicle door (600), and the vehicle door (600) needs to be disassembled when wiring is arranged in a rubber pipe connected with the vehicle door (600) and with the vehicle body, which leads to a long time for installation, and causes the buckles of the vehicle door (600) to be easily damaged and the vehicle door (600) to be loosened, and causes a vibration noise; and the installation difficulty of side cameras is reduced, and promotion and application of the product are facilitated.
