Swellable Sealing Lip for Liquid-Resistant Panel Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel joints are prone to liquid ingress, leading to potential damage and mold formation, with current sealing solutions being either expensive or providing limited durability and flexibility.
Innovation Solution
Incorporating a swellable sealing lip into the panel's retaining profiles, which absorbs liquids and expands to create a hydraulic seal, maintaining flexibility while preventing liquid penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If joints are glued during laying to prevent liquid ingress, then moisture protection is improved, but laying cost increases considerably and flexibility of panel connections is limited
Solution Approach 1:
The sealing lip is designed to swell automatically upon contact with liquid, creating a hydraulic seal without requiring external intervention such as glue application. The panel connection system serves itself by using the liquid's own presence to trigger the sealing mechanism, eliminating the need for additional sealing materials or complex installation procedures.
Solution Approach 2:
The sealing lip undergoes a parameter change in its physical state by swelling when exposed to liquid. This volume expansion transforms the sealing lip from a non-sealing state to a hydraulic seal state, providing moisture protection dynamically rather than through static structural complexity.
2Reliability
If laid panels are treated with a sealing to prevent liquid ingress, then moisture protection is improved to some extent, but the sealing durability is much shorter than panel lifetime and requires reapplication
Solution Approach 1:
The sealing mechanism is self-activating and self-sustaining. Upon liquid contact, the swelling material automatically creates and maintains the hydraulic seal throughout the panel's lifetime, eliminating the need for periodic reapplication or maintenance of external sealings.
Solution Approach 2:
The sealing lip is made from a composite or specially formulated swelling material that combines sealing functionality with long-term durability. This material integrates the sealing function directly into the panel structure, ensuring the sealing lasts as long as the panel itself.
3Reliability
If a swellable sealing lip is incorporated into retaining profiles, then sealing effectiveness is improved, but the complexity of the retaining profile increases
Solution Approach 1:
The sealing lip is merged with the retaining profile, combining the connection function and sealing function into a single integrated component. This eliminates the need for separate sealing elements and reduces overall system complexity while maintaining effective sealing.
Solution Approach 2:
The retaining profile is designed to serve multiple functions: mechanical connection of panels and hydraulic sealing against liquid ingress. By making the retaining profile universal, the design avoids additional components and simplifies the overall structure.

AI summary
A panel comprises a swellable sealing lip. The panel comprises a panel top side and a panel bottom side and at least four panel edges arranged mutually facing each other in pairs, with complementary retaining profiles provided in pairs at the mutually facing panel edges, wherein the retaining profiles are configured such that at a retaining profile of one panel further panels with a complementary retaining profile can be mounted. In this case, at least one retaining profile comprises a swellable sealing lip at least partially along its longitudinal axis. Moreover, an arrangement of such panels and a method for producing such panels are proposed. In summary, the above-described panel has the advantage that panel joints can be protected against ingress and penetration of liquids in a particularly good and easy way without applying permanent, additional stresses to the connection of joined retaining profiles.
