Solution Overview

Problem

The installation and removal of vehicle seats with electrical connections are time-consuming due to the manual operation of connectors, which requires frequent manual insertion and locking, and this process is infrequent, especially during maintenance.

Innovation Solution

A plug-in unit with a modular structure comprising a housing, plug, triggering unit, and drive unit, where the triggering unit unlocks the drive unit to move the plug from a rest position to a plug-in position, allowing automatic contact with a socket, and is coupled with a seat lock for automatic electrical connection establishment and release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual connector operation is used for seat installation and removal, then the electrical connection process requires frequent manual steps, but this increases the time and effort required for installation and removal

Engineering Contradiction:
Improveease of electrical connection operationVSAvoidtime for installation and removal
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The connector is designed to automatically establish electrical connections when the seat is installed and automatically disconnect when removed. The coupling mechanism self-activates the electrical plug engagement without requiring manual intervention, making the system serve itself rather than requiring user operation for each connection event.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mechanical coupling mechanism and electrical connection system are merged into a single integrated unit. When the mechanical coupling engages or disengages, it simultaneously activates or deactivates the electrical plug connection, combining two functions (mechanical attachment and electrical connection) into one unified operation.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If manual connector operation is used, then the process steps are simple to understand, but the frequent manual insertion and locking is time-consuming

Engineering Contradiction:
Improveinstallation and removal speedVSAvoidconnector mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The mechanical coupling mechanism and electrical connection system are merged into a single integrated unit. When the mechanical coupling engages or disengages, it simultaneously activates or deactivates the electrical plug connection, combining two functions (mechanical attachment and electrical connection) into one unified operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The electrical plug is pre-positioned within the coupling mechanism housing, ready for automatic engagement. The spring mechanism is pre-loaded to provide the necessary force for plug insertion, so that when the mechanical coupling is activated, the electrical connection is immediately established without requiring additional preparation or manual steps.

Inventive Principle:
Principle #10Preliminary action
