Seal Profile Segmentation for Infill Thickness Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inner seals in profile frame constructions provide a reduced sealing effect when compensating for infill thickness differences, as they rely on additional sealing elements that cover grooves, leading to compromised sealing performance.
Innovation Solution
The inner seal features two linear slits with a curved or angular course, allowing for optimal force transmission and a spacious receiving chamber for additional seals, ensuring a consistent sealing effect across the profile area, including the groove area, with a central tear-off web connecting the slits for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a groove in the sealing profile is closed by a horizontal removable web to accommodate additional sealing elements, then infill thickness compensation is enabled, but the sealing effect is reduced in the area of the cover
Solution Approach 1:
The sealing profile is divided into first and second sealing profile sections separated by slits, allowing the second section to be removed independently. This segmentation enables infill thickness compensation while maintaining the sealing integrity of the first section, resolving the contradiction between adaptability and sealing reliability.
Solution Approach 2:
The second sealing profile section is extracted as a removable component that can be taken out to create space for additional sealing elements. This extraction allows infill thickness adjustment without compromising the main sealing function, as the first sealing profile section remains in place to ensure optimal sealing effect.
2Adaptability or versatility
If the second sealing profile section is removed to create space for additional seals, then infill thickness compensation is achieved, but force transmission is compromised
Solution Approach 1:
The sealing profile is segmented into removable and permanent sections. The first sealing profile section remains to ensure continuous force transmission, while the removable second section allows seal height adjustment. This segmentation resolves the contradiction between adaptability and force transmission.
3Force
If two slits with curved or angular course are provided to separate sealing profile sections, then optimal force transmission is achieved, but device complexity increases
Solution Approach 1:
The slits are designed with curved or angular courses instead of straight lines, which optimizes force distribution and transmission across the sealing profile. This curved geometry allows the slits to follow the stress lines, improving force transmission while the central tear-off web simplifies the overall structure, balancing complexity with performance.

AI summary
The seal (1) has a sealing profile (3) comprising two sealing profile sections (6, 7) and tear-off webs (9b, 9c) between the two sealing profile sections. One of the sealing profile sections is removed by destruction of the tear-off webs, and a groove fixed by another one of the sealing profile sections is accessed from outside. The two sealing profile sections are separated from each other by an angled or curved slot (11c). Breadth of the slot is measured in such a manner that wall sections of the sealing profile sections lie together in due form.
