Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly devices for sealing vehicle openings face challenges in achieving precise positioning and uniform contact pressure due to irregular shapes and varying geometries, requiring complex adjustments and high investment costs, especially when dealing with different vehicle types or cut-out shapes.
Innovation Solution
The assembly device features counter-pressure elements and pivoting supports that allow it to follow the vehicle flange automatically, maintaining consistent contact pressure and positioning regardless of curve radii, using counter-pressing elements and a pneumatic cylinder to adjust pressure force and prevent expansion or compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a robot with programming is used to guide the assembly device along the flange surface, then precise positioning and uniform contact pressure can be achieved, but investment costs and device complexity increase significantly
Solution Approach 1:
The assembly device performs its own positioning and orientation automatically through the self-steering mechanism. The counter-pressure elements on the pivoting support follow the flange contour autonomously without external guidance, making the system self-sufficient in navigation and positioning tasks
Solution Approach 2:
The pivoting support acts as an intermediary mechanism between the base support and the pressure roller. It translates the contour-following motion into automatic positioning and orientation of the pressure roller, mediating the complex guidance task through a simple mechanical pivot joint
2Manufacturing precision
If the assembly device is guided exactly along the flange surface to achieve precise positioning, then sealing quality improves, but adaptability to different vehicle types and geometries decreases
Solution Approach 1:
The pivoting support is designed to be dynamically adjustable, allowing the assembly device to adapt its orientation and positioning to different flange geometries. The pivot joint enables continuous adjustment of the pressure roller's angle and position to match various contour shapes
Solution Approach 2:
The self-steering mechanism with pivoting support serves multiple functions: it follows the flange contour, positions the pressure roller accurately, maintains proper orientation, and adapts to different geometries. This single mechanism replaces multiple specialized components needed for different vehicle types
3Manufacturing precision
If complex adjustments are made to control clamping force and strain avoidance, then bonding quality improves, but ease of operation and productivity deteriorate
Solution Approach 1:
The system automatically maintains defined contact pressure through the self-steering mechanism. The counter-pressure elements and pivoting support work together to naturally regulate the pressure distribution along the flange contour without requiring manual adjustment or complex control systems
Solution Approach 2:
The mechanical design provides inherent feedback through the pivoting support's natural tendency to align with the flange contour. As the counter-pressure elements follow the surface geometry, the pivot joint automatically adjusts the pressure roller's position to maintain optimal contact pressure, creating a self-regulating system

AI summary
The invention relates to a mounting device (1) for attaching a seal (37) to an end face (35) of a flange (34) of a vehicle opening (33). The mounting device comprises a base support (2), to which a first pressure roller (5) with a pivot axis (11) and a second pressure roller (6) with a pivot axis (12) are connected. The pressure rollers (5, 6) are designed to press the seal (37) onto the end face (35). Counter-pressure elements for guiding the two pressure rollers (5, 6) along a rear side (36) of the flange (34) facing away from the end face (35) are associated. At least one pivoting support (3, 4) is pivotably mounted on the base support (2). One of the pressure rollers (5, 6) and two associated counter-pressure elements are rotatably mounted on the at least one pivoting support (3, 4).
