Connecting Profile Strip Sealing Joint Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection profile strips for components adjacent to plaster lack effective sealing and manageability, particularly when bridging larger joints, as the sealing tape and its support strip often protrude or hinder movement.
Innovation Solution
A connection profile strip with an independent receiving space for the flexible strip connected to the sealing tape, allowing better handling and sealing performance, including wider joints, by accommodating the strip fully without hindering its exit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing tape and support strip are attached to the sealing leg without a dedicated receiving space, then the structure is simpler, but the sealing function and manageability deteriorate when bridging larger joints
Solution Approach 1:
The flexible strip is nested within the receiving space of the profile strip. When the sealing tape is attached to the sealing leg, the flexible strip is folded and stored inside the receiving space, similar to a nested doll structure. This allows the sealing system to maintain a compact form while having the capability to extend for larger joints.
Solution Approach 2:
The receiving space is pre-formed and prepared in advance to accommodate the flexible strip before installation. This preliminary preparation ensures that when the sealing tape needs to bridge larger joints, the flexible strip is already positioned and ready to be deployed, improving both sealing reliability and manageability.
2Object-affected harmful factors
If the flexible strip is completely contained within the receiving space, then protection is improved, but the ability to exit and bridge joints may be hindered
Solution Approach 1:
The receiving space is designed with dynamic characteristics that allow it to accommodate the flexible strip in both contained and extended states. The opening of the receiving space is positioned and sized to enable the flexible strip to exit smoothly when needed, while maintaining protection when contained. This dynamic design resolves the contradiction between protection and ease of operation.
3Ease of operation
If the receiving space is integrated with the sealing leg, then the structure is more compact, but handling and sealing performance deteriorate
Solution Approach 1:
The profile strip is segmented into distinct functional parts: the sealing leg for attachment, the receiving space for storage, and the flexible strip for bridging. This segmentation allows each component to perform its specific function optimally, improving handling and sealing performance while maintaining reasonable structural complexity through modular design.

AI summary
A connecting profile strip (1) for building components adjacent to plaster comprises a plastering leg (3) and a sealing leg (2) on which a sealing strip (6) is arranged via a support strip (7). Opposite the sealing leg (2), a profile part (12) is provided on the plastering leg (3), forming a receiving space (17) for a strip (22) that is initially folded. This strip is connected on one side to the profile part (12) and on the other side to the support strip (7) for the sealing strip (6). When the sealing strip (6) has detached from the sealing leg (2), the strip (22) bridges the gap between the sealing strip (6), which remains adhered to the building component, and the plastering leg (2) of the connecting profile strip (1).
