Universal Base Plate for Vehicle Electrical Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, particularly aircraft, composite materials with integrated threaded bushes at specific positions make it difficult to exchange electrical devices with different attachment hole patterns, and the initial installation or exchange of electrical devices is complex due to the need for both mechanical and electrical connections.
Innovation Solution
A universal base plate with a first connection region and a universal rear wall with a second connection region, allowing for mechanical engagement and electrical connection through matching electrical connectors, which can be either mechanical or non-contacting coil pairings, facilitating a secure and reliable connection without the need for additional screw connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If threaded bushes are integrated at specifically predetermined positions in composite wall materials, then mechanical connections are securely established, but exchanging electrical devices with different attachment hole patterns becomes difficult
Solution Approach 1:
The base plate is designed as a universal mounting component with multiple threaded bushes at predetermined positions, serving as an intermediary between the wall and various electrical devices. This universal base plate can accommodate different electrical devices with different attachment hole patterns by providing a standardized mounting interface, thus resolving the contradiction between secure mechanical connection and adaptability to different devices
Solution Approach 2:
The base plate acts as an intermediary element between the wall structure and the electrical device. Instead of directly attaching the electrical device to the wall with threaded bushes, the base plate mediates the connection, allowing the wall to maintain its predetermined threaded bush positions while enabling flexible attachment of various electrical devices through the base plate's multiple mounting points
2Reliability
If both mechanical connections and electrical connections are established during initial installation, then reliable electrical supply and data transmission are achieved, but the installation process becomes extremely involved and time-consuming
Solution Approach 1:
The base plate integrates both mechanical mounting functions and electrical connection functions into a single component. The electrical connectors are built into the base plate structure, allowing simultaneous establishment of both mechanical attachment and electrical connections through a single integrated interface, thereby reducing the number of separate steps required during installation
Solution Approach 2:
The electrical connectors are pre-integrated into the base plate during manufacturing, before installation occurs. This preliminary integration of electrical connections into the mounting structure eliminates the need for separate cable routing and connector attachment steps during installation, significantly reducing installation time while maintaining connection reliability

AI summary
An apparatus for electrically connecting and attaching an electrical device to a wall in a vehicle is provided. The apparatus provides a universal base plate with a first connection region with a first electrical connector arranged therein and a universal rear wall with a second connection region with a second electrical connector positioned therein. The universal base plate comprises attachment means for attachment to a wall in a vehicle, wherein the universal rear wall is designed to form part of an electrical device or to be attached thereto. The rear wall and the base plate comprise largely corresponding directions of extension and are designed to be brought into mechanical engagement with each other, wherein during mechanical engagement the first and the second connection regions are arranged adjacent to each other in such a manner that the first electrical connector and the second electrical connector establish a mutual connection.
