Door Trim USB Jack Layout for Rainwater and Cable Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door trim modules for vehicle side doors lack a USB jack, making it difficult to connect smartphones stored in the storage part using a USB cable due to rainwater ingress and cable obstruction issues when closing the door.
Innovation Solution
A door trim module with a bulging part that houses a smartphone and features a USB jack positioned below, connected via a vertical connection hole, preventing rainwater ingress and ensuring easy cable connection while avoiding cable obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a USB jack is formed on the door trim, then connectivity for smartphones is improved, but rainwater may enter the USB jack when the door is open
Solution Approach 1:
The USB jack is repositioned from a horizontal orientation to a downward orientation, changing the spatial dimension of the connection hole. This dimensional change allows the jack to be located below the bulging part, directing any entering water downward and away from the USB jack interior, thus resolving the rainwater ingress problem while maintaining connectivity functionality
2Adaptability or versatility
If a USB jack is formed on the door trim, then connectivity for smartphones is improved, but the USB cable may be sandwiched between the door and the vehicle body when closing the door
Solution Approach 1:
The connection hole is oriented vertically downward instead of horizontally, creating a spatial dimension that allows the USB cable to extend downward below the door trim. This dimensional reorientation prevents the cable from being trapped between the door and vehicle body during closing, eliminating the cable obstruction problem while preserving USB connectivity
3Ease of operation
If the USB jack is positioned on the door trim surface, then ease of connection is improved, but the structure becomes more complex to prevent rainwater ingress
Solution Approach 1:
The USB jack is merged with the bulging part structure, where the connection hole is formed as an integral part of the bulging part's lower surface. This merging eliminates the need for separate waterproofing structures or complex mounting mechanisms, reducing overall structural complexity while maintaining ease of cable connection through the downward-oriented hole

AI summary
A USB jack is provided below a bulging part of a door trim. Therefore, the bulging part can prevent rainwater from entering the USB jack. As a result, the USB jack can be provided on the door trim. In addition, since a connection hole is provided in the bulging part, a USB cable can be arranged to extend from an internal space of a storage part to a lower space of the bulging part through the connection hole. As a result, although the USB jack is provided below the bulging part, the USB jack and a smartphone stored in the storage part can be connected by the USB cable.
