Integrated Tailgate Handle Switch Assembly Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing outside handle switch assemblies for vehicle tail gates have separate mounting and wiring for the rear camera and license plate lamp, increasing assembly complexity and requiring multiple wiring stages.
Innovation Solution
An integrated outside handle switch assembly that combines the rear camera and license plate lamp with a shared substrate and common wiring, reducing assembly stages and wiring complexity, and features an actuator with a cantilever extension portion for guiding the operating force without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the outside handle switch assembly and license plate lamp are mounted separately, then each component can be independently installed and maintained, but the assembly complexity increases and multiple wiring stages are required
Solution Approach 1:
The patent combines the outside handle switch assembly and license plate lamp into a single integrated unit. The license plate lamp is mounted on the same housing structure as the switch assembly, and both components share common wiring connections through the vehicle's body, thereby reducing assembly complexity and eliminating the need for separate wiring stages while maintaining ease of installation and maintenance
2Reliability
If separate wiring is provided for the outside handle switch assembly and license plate lamp, then each component has dedicated electrical connections, but the wiring complexity and number of connections increase
Solution Approach 1:
The integrated assembly allows both the outside handle switch and license plate lamp to share common wiring infrastructure. The housing structure provides universal mounting and electrical connection points that serve both components simultaneously, reducing the total number of wiring connections while maintaining reliable electrical connectivity for each function

AI summary
An integrated outside handle switch assembly for a rear trunk lid or tail gate is mounted in the rear trunk lid or tail gate and is operated at the time of opening the tail gate. The outside handle switch assembly may include: an upper housing configured to be mounted on the tail gate; a lower housing configured to be assembled to the upper housing below the upper housing; a substrate configured to be fixed at a lower portion of the upper housing; a switch configured to be operated at the time of opening the tail gate and mounted on the substrate; and a lamp configured to illuminate a license plate attached to the tail gate and be mounted on the substrate.
