Vehicle Seat Switch Mounting Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle device systems, such as those with key-operated switches for detachable vehicle seats, face challenges in optimizing installation space utilization due to the fixed location of the switch, which becomes a constraint with complex seat adjustments.
Innovation Solution
The key-operated switch is integrated with the vehicle device and interacts with a longitudinally displaceable contact carriage, ensuring electrical contact independence from the device's position, allowing the switch and contact carriage to move together, thus optimizing installation space by relocating the switch's presence to the vehicle device and freeing up space in the mount area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the key-operated switch is assigned to the seat bearing (mount), then the electrical contact control is established, but the installation space next to the vehicle seat is occupied and becomes narrowly dimensioned with complex seat adjustments
Solution Approach 1:
The patent inverts the conventional assignment by moving the key-operated switch from the stationary mount to the movable vehicle seat. This inversion resolves the space conflict by making the switch relocate with the seat, freeing up the mount area while maintaining control functionality through interaction with the contact carriage on the mount.
Solution Approach 2:
The patent applies dynamics by making the key-operated switch longitudinally displaceable together with the vehicle seat on the mount. The switch is fastened to the seat in such a way that it moves with the seat's longitudinal displacement while maintaining its functional relationship with the contact carriage through the guide rail system.
2Adaptability or versatility
If the vehicle device is longitudinally displaceable on the mount, then the adjustment flexibility is improved, but the maintenance of electrical contact becomes difficult without a corresponding contact mechanism
Solution Approach 1:
The patent introduces a contact carriage as an intermediary element that moves along the guide rail on the mount. This contact carriage maintains electrical contact with the vehicle seat's key-operated switch throughout the longitudinal displacement range, enabling both adjustment flexibility and reliable electrical contact maintenance through the mediator's tracking motion.

AI summary
A vehicle device system for a motor vehicle, having at least one vehicle device, in particular a vehicle seat or vehicle table, and comprising a mount fastened or fastenable to a vehicle body for detachably locking the vehicle device to the vehicle body, and comprising a key-operated switch, which establishes or interrupts at least one electrical contact between the vehicle device and the vehicle depending on its switching position. It is provided that the key-operated switch is fastened on the vehicle device, which is longitudinally displaceably mounted/mountable on the mount, and interacts with a contact carriage, which is longitudinally displaceably mounted on the mount.
