Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle door installation devices are often complex and require significant effort to continuously monitor the door's position, which can lead to inefficient and energy-intensive operation.
Innovation Solution
A motor vehicle door installation device featuring an electrical drive and adjustment mechanism, where the adjustment is split into two parts with a drive area and a sliding element, and integrated sensors monitor the movement, allowing for secure and energy-efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex door stay or ejector device is used to open the door, then the door can be opened at least partially, but the design becomes complex and monitoring the actuating movement requires considerable effort
Solution Approach 1:
The actuating means is divided into two independent parts: a drive region that provides the actuating force and a sliding element that contacts the door. This segmentation allows each part to be optimized independently and simplifies the overall monitoring system, as only the movement of the sliding element needs to be detected
Solution Approach 2:
The sliding element is extracted as a separate, movable component that can be monitored independently by the sensor. This extraction allows the monitoring function to be simplified to only track the position of the sliding element rather than monitoring the entire complex mechanism
2Reliability
If continuous monitoring of the actuating movement is implemented, then the door position can be tracked, but energy consumption increases
Solution Approach 1:
The sensor is integrated into the actuating means itself, allowing it to monitor its own position and movement. This self-monitoring capability provides reliable door position tracking while consuming minimal energy, as the system only activates monitoring when the actuating means is in motion
Solution Approach 2:
The sensor provides continuous feedback on the position of the sliding element, enabling the control system to respond to the actual door opening progress. This feedback mechanism ensures reliable monitoring while allowing the system to stop or adjust operation based on real-time position information
3Reliability
If the actuating means is integrated into the body, then the door can be opened safely, but the design becomes more complex
Solution Approach 1:
The sliding element is nested within the actuating means, moving in a guide channel that is part of the drive region. This nested arrangement allows the actuating means to be compactly integrated into the vehicle body while maintaining the ability to provide safe and controlled door opening
