Door-Wing Floor Seal Adapter Kit for Installation Tolerances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing doors, particularly smoke protection doors, face challenges in effectively sealing the gap between the door leaf and the floor due to installation tolerances, requiring replacement of the entire door leaf when gaps exceed acceptable limits.
Innovation Solution
A kit of parts comprising a door leaf-side retaining profile, a seal-side retaining profile, and adapter strips with complementary contours allows for adjustable sealing by interposing adapter strips between the profiles to accommodate varying floor heights without replacing the door leaf.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire door leaf is replaced to accommodate floor height variations, then sealing effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The door assembly is segmented into modular components: the door leaf, the floor seal, and the adapter strip. This allows the adapter strip to be independently adjusted to compensate for floor height variations, eliminating the need to replace the entire door leaf while maintaining sealing effectiveness.
Solution Approach 2:
The adapter strip serves as an intermediary element between the door leaf-side retaining profile and the seal-side retaining profile. It mediates the height difference caused by floor variations, enabling the floor seal to maintain proper engagement with the door leaf without requiring door leaf replacement.
2Adaptability or versatility
If adapter strips are used to adjust for floor height variations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adapter strip is designed with universal compatibility features: its contours match both the door leaf-side retaining profile and the seal-side retaining profile. This multi-functional design allows a single adapter strip component to serve multiple adjustment purposes across different installation scenarios, reducing the need for multiple specialized parts.
Solution Approach 2:
The adapter strip enables parameter adjustment of the floor seal assembly by changing its vertical position relative to the door leaf. By interposing adapter strips of varying thicknesses, the system adapts to different floor heights through parameter modification rather than requiring different component designs.
3Device complexity
If the floor seal is directly attached to the door leaf without adapter strips, then device complexity is reduced, but adaptability to different floor heights deteriorates
Solution Approach 1:
The floor seal assembly is made dynamically adjustable through the use of adapter strips. Rather than a fixed direct attachment, the system allows for vertical positioning adjustments by selecting appropriate adapter strip thicknesses, enabling the same basic assembly to adapt to varying floor heights while maintaining simple component design.

AI summary
In order to ensure the sealing effect for a door in the area of the floor even in unfavorable installation situations with little effort, the invention provides a parts set (32) with a door leaf-side retaining profile (34) for positively holding a floor seal (24) on a door leaf (22), a floor seal (24) with a seal-side retaining profile (38) for positively engaging in the door leaf-side retaining profile (34), and at least one adapter strip (46) for interposing between the door leaf-side retaining profile (34) and the floor seal (24), wherein the at least one adapter strip (46) has a first retaining profile contour (48) on a side which is the upper side during intended use, which corresponds to the contour of the seal-side retaining profile (38), and a second retaining profile contour (50) on a side which is the lower side during intended use, which corresponds to the contour of the door leaf-side retaining profile (34).
