Solution Overview
Problem
Existing solutions for connecting portable electronic devices to motor vehicles are inconvenient and require time, attention, and cumbersome cables for connection and disconnection, and do not provide a stable and clear view of the device's display during vehicle travel.
Innovation Solution
A dashboard assembly with a connector system that includes a snap-fit mechanism for secure attachment of a support to the dashboard, featuring internal electrical contacts for 12-V or 24-V supply and data signals, and a reinforcement ring for stability, allowing direct electrical connection without additional cables, and automatic opening and closing of the hatch for easy device installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If portable electronic devices are connected to motor vehicles using existing support systems with cables, then electrical supply and data connection are achieved, but the connection and disconnection operations are inconvenient and require time and attention
Solution Approach 1:
The patent combines the mechanical support function and electrical connection function into a single integrated connector assembly. The support (14) with its end (12) directly engages with the connector (5) housing, while electrical contacts (24, 26) are built into the same assembly, eliminating the need for separate cable connections and simplifying the overall connection process.
Solution Approach 2:
The connector assembly incorporates automatic electrical connection through the engagement mechanism itself. When the support end (12) is inserted into the connector seat (7), the electrical contacts (24, 26) automatically establish connection without requiring manual plugging of separate cables, making the system self-servicing for the connection operation.
2Ease of operation
If portable electronic devices are connected using existing cable-based systems, then electrical supply is provided, but the cables are relatively cumbersome
Solution Approach 1:
The patent extracts and eliminates the separate cable component from the connection system. The electrical connection is achieved directly through the connector assembly (5) integrated with the support (14), removing the need for external cables and their associated connectors, clips, and routing infrastructure.
Solution Approach 2:
The mechanical support structure and electrical connection system are merged into a single integrated assembly. The support (14) with end (12) directly engages the connector (5) housing, and electrical contacts are built into the same structure, eliminating the need for separate cable connections and simplifying the overall connection process.
3Ease of operation
If a connector system is integrated into the dashboard, then cable-free connection is achieved, but secure attachment and stability against vibrations must be ensured
Solution Approach 1:
The connector housing (5) incorporates a reinforcement ring (19) that provides structural rigidity and resistance to vibrational forces. The curved, ring-shaped reinforcement structure distributes mechanical stresses and enhances the overall stability of the integrated connector-support assembly during vehicle operation.
Solution Approach 2:
The connector assembly is segmented into distinct functional components: the connector housing (5) for electrical connection, the support (14) for mechanical positioning, and the reinforcement ring (19) for structural stability. This segmentation allows each component to be optimized for its specific function while working together as an integrated system.
4Productivity
If the connector includes internal electrical contacts for power and data, then direct electrical connection is achieved, but the connector structure becomes more complex
Solution Approach 1:
The electrical contacts (24, 26) are integrated directly into the connector housing (5) structure, combining the electrical connection function with the mechanical housing. This integration eliminates the need for separate cable assemblies and reduces the overall system complexity despite adding internal electrical components.
Solution Approach 2:
The connector assembly serves multiple functions simultaneously: mechanical support positioning, electrical power transmission, and data communication. The integrated design allows a single component to perform what would traditionally require multiple separate systems, improving productivity without proportionally increasing complexity.

AI summary
A dashboard assembly (1) of a motor vehicle includes a dashboard (2) and a connector (5), which is set in a hole of the dashboard (2) and defines a seat (7) which is accessible by opening a hatch (10); the connector has an electrical contact for the 12-V or 24-V electrical supply and at least one electrical contact for transmission of data and is provided with at least one retention hole (22) for withholding a support (14) of a portable electronic device engaging in the seat (7); also provided is a reinforcement system around at least part of the seat (7) for withstanding vibrations and forces exerted, in use, by the support (14).
