Vehicle Interior Drive Control Against Unwanted Position Shift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive devices for adjusting vehicle interior assemblies often require self-locking mechanisms, which lead to inefficiencies, increased weight, and installation space, and are prone to unintentional adjustments due to external forces, particularly in rough road conditions.
Innovation Solution
A drive device with a motor-type adjusting drive, kinematic mechanism without self-locking, and electronic detection and control systems to counteract undesired adjustments by generating an opposing force in response to detected external forces, using sensors and control devices to maintain components in target positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a self-locking mechanism is used in the adjusting drive or kinematic adjusting mechanism, then the interior assembly can be prevented from unintentional adjustment due to external forces, but the efficiency deteriorates and installation space and weight increase
Solution Approach 1:
The patent replaces the mechanical self-locking system with an electronic control system. The control device detects external forces acting on the interior assembly and activates the motor-type adjusting drive to generate counteracting forces, thereby preventing unintentional adjustments without requiring mechanical self-locking features. This substitution eliminates the efficiency losses and space requirements associated with mechanical self-locking mechanisms.
Solution Approach 2:
The patent introduces an electronic control device as an intermediary between the exterior forces and the adjusting mechanism. This control device monitors the state of the interior assembly and coordinates the adjusting drive's response to external forces, providing a sophisticated mediation approach that maintains reliability while avoiding the drawbacks of direct mechanical self-locking.
2Reliability
If a self-locking mechanism is used in the adjusting drive or kinematic adjusting mechanism, then the interior assembly can be prevented from unintentional adjustment due to external forces, but the installation space and weight increase
Solution Approach 1:
The patent replaces heavy mechanical self-locking components with a lighter electronic control system and motor-type adjusting drive. The electronic detection device and control device require minimal additional weight compared to robust mechanical self-locking mechanisms, thereby reducing the overall weight of the drive device while maintaining the capability to prevent unintentional adjustments.
3Reliability
If a self-locking mechanism is used in the adjusting drive or kinematic adjusting mechanism, then the interior assembly can be prevented from unintentional adjustment due to external forces, but the installation space increases
Solution Approach 1:
The patent substitutes compact electronic components for bulky mechanical self-locking structures. The electronic detection device, control device, and motor-type adjusting drive occupy significantly less space than equivalent mechanical self-locking mechanisms, allowing for more efficient use of installation space in the vehicle interior.
4Loss of energy
If the adjusting drive and kinematic adjusting mechanism are designed without self-locking features, then efficiency improves and installation space and weight are reduced, but the interior assembly becomes susceptible to unintentional adjustment due to external forces
Solution Approach 1:
The patent implements a feedback control system where the electronic detection device continuously monitors the interior assembly for external forces and communicates this information to the control device. The control device then activates the motor-type adjusting drive to generate counteracting forces, creating a closed-loop feedback mechanism that prevents unintentional adjustments while maintaining high efficiency without self-locking features.
Solution Approach 2:
The system provides self-service by automatically detecting external forces and generating counteracting forces without requiring mechanical self-locking features. The electronic detection device and control device work together to autonomously maintain the interior assembly's position, eliminating the need for passive mechanical locking mechanisms and thereby improving efficiency.

AI summary
It is provided a drive device for adjusting an interior assembly of a vehicle, having, at least comprising, a motor-type adjusting drive for generating an adjusting force, a kinematic adjusting mechanism to be driven by the adjusting drive for transmitting an adjusting force generated by the adjusting drive to the interior assembly, a control device for controlling the adjusting drive, and an electronic detection device for detecting an adjustment event, in which at least one external force acts on the drive device and/or the interior assembly. The control device is configured to generate an opposing force via the motor-type adjusting drive in response to the detection of the adjustment event, which counteracts an adjustment of the interior assembly due to the external force.
