Prestressed Inner Profile Gap Seal for Deformed Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gap sealing systems for doors are inefficient due to the large size of the sealing profile, which leads to deformation and increased wear, and are unable to reliably seal larger gaps under torsion or convex/concave deformations.
Innovation Solution
A sealing profile is mounted in a separate inner profile that is prestressed and guided into a fastening profile, allowing for a smaller, more economical seal that can deform less and accommodate larger gaps through adjustment, with optional elastic spring elements for even compression and reduced wear, and a cover profile for aesthetic and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large sealing profile is used to bridge larger gaps, then the gap can be sealed, but the sealing profile undergoes major deformation and experiences increased wear
Solution Approach 1:
The sealing system is divided into two separate profiles: a fastening profile that remains stationary and an inner profile that moves. The sealing profile is mounted on the inner profile, which can adjust its position independently. This segmentation allows the seal to adapt to gap variations without undergoing excessive deformation, as the inner profile's movement absorbs the adjustment needs.
Solution Approach 2:
The inner profile is designed to be movable relative to the fastening profile, enabling dynamic adjustment to accommodate torsion and convex/concave deformations of the door leaf. This dynamic capability allows the sealing profile to maintain optimal contact and sealing performance under varying conditions without experiencing major deformation or increased wear.
2Stability of the object's composition
If a rigid sealing system is used, then structural stability is maintained, but it reacts insufficiently to torsion or convex/concave deformation of the door leaf
Solution Approach 1:
The inner profile is designed to be movable relative to the fastening profile, enabling dynamic adjustment to accommodate torsion and convex/concave deformations of the door leaf. This dynamic capability allows the sealing profile to maintain optimal contact and sealing performance under varying conditions without experiencing major deformation or increased wear.
Solution Approach 2:
The system allows for parameter changes in the position of the inner profile relative to the fastening profile. By adjusting the position parameters of the inner profile, the sealing system can adapt to different door deformations while maintaining structural stability and effective sealing.
3Reliability
If a smaller sealing profile is used to reduce wear and volume, then economy and durability improve, but the ability to bridge larger gaps is reduced
Solution Approach 1:
The sealing system is divided into two separate profiles: a fastening profile that remains stationary and an inner profile that moves. The sealing profile is mounted on the inner profile, which can adjust its position independently. This segmentation allows the seal to adapt to gap variations without undergoing excessive deformation, as the inner profile's movement absorbs the adjustment needs.
Solution Approach 2:
The inner profile is designed to be movable relative to the fastening profile, enabling dynamic adjustment to accommodate torsion and convex/concave deformations of the door leaf. This dynamic capability allows the sealing profile to maintain optimal contact and sealing performance under varying conditions without experiencing major deformation or increased wear.

AI summary
A gap seal is provided for sealing a door gap between a frame (35) and a door (36) or between two doors (37;38), comprising a fastening profile (1;2), a receiving groove (3) for a sealing profile (4), and the sealing profile (4) consisting of a retaining profile (5) and a sealing profile (6), as well as a cover profile (7). This seal permanently and reliably seals a gap between the door leaf and the frame or between two adjacent door leaves as completely as possible and independently of any torsion or concave or convex deformation of a door leaf. This is achieved by the sealing profile (4) with its retaining profile (5) being mounted in the receiving groove (3) of an inner profile (9), which is permanently pre-tensioned outwards and projecting in the fastening profile (1;2) in the closing direction of a door (36;37;38), abutting its closing surface and sliding parallel into the fastening profile (1;2).
