Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying door seals to motor vehicle doors lack precision and are costly, with known devices being prone to distortion, high investment costs, and insufficient positioning accuracy, especially in mass manufacturing.
Innovation Solution
A device comprising a receiving device with a holding mechanism, a guide track for alignment, and a rotation mechanism to ensure precise alignment and application of the door seal, allowing for easy manual or automated alignment and application with high accuracy and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a template is used for aligning the door seal, then the alignment process can be performed manually, but the template easily distorts and positioning accuracy deteriorates
Solution Approach 1:
The alignment system is divided into separate functional components: a receiving device for the door, a guide device with guide track for seal alignment, and a rotation device. This segmentation allows each component to perform its specific function without interfering with others, preventing the distortion issues that plague integrated template systems.
Solution Approach 2:
The patent replaces the purely mechanical template system with a hybrid system that incorporates a rotation device (which can be manually or automatically actuated) to orient the door and seal. This substitution allows for more precise control of the alignment process while maintaining operational simplicity.
2Manufacturing precision
If complex devices are used for door seal application, then positioning accuracy can be improved, but investment costs and device complexity increase
Solution Approach 1:
The receiving device serves multiple functions: it holds the door, positions it relative to the guide device, and rotates it to the correct orientation. This multi-functionality eliminates the need for separate complex positioning and orientation mechanisms, reducing overall device complexity while maintaining high positioning accuracy.
Solution Approach 2:
The guide track inherently guides the door seal into the correct position along the door contour. The geometry of the guide track itself provides the positioning function, eliminating the need for additional active control mechanisms or complex positioning devices.
3Device complexity
If manual alignment methods are used, then device costs are reduced, but alignment precision and application speed deteriorate
Solution Approach 1:
The system allows for dynamic operation where the receiving device can be rotated manually for cost-effectiveness or automatically for increased productivity. The rotation device can be actuated by a rotation motor to automatically orient multiple doors and seals, significantly increasing application speed while maintaining the option for manual operation when cost is the primary concern.
4Productivity
If the door is held suspended on a hanging conveyor, then continuous production is possible, but accessibility to upper and lower sides of the door deteriorates
Solution Approach 1:
The door is pre-positioned and clamped to the receiving device before rotation and alignment operations. This preliminary securing allows subsequent alignment and application operations to be performed easily on all sides of the door, including upper and lower sides, without compromising the continuous production capability provided by the hanging conveyor integration.

AI summary
A device for aligning a door seal when the door seal is applied to a door of a motor vehicle includes a receiving device for receiving the door in a defined manner, a holding device arranged on the receiving device for holding the door, a guiding device arranged on the receiving device and having a guiding strip for aligning the door seal in relation to the door when the door seal is applied to the door, and a rotation device for turning the receiving device about at least one axis of rotation.
