Plaster Connection Profile With 3D-Movement Sealing Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection profiles for components adjacent to plaster, such as window and door frames, do not allow for a permanent, tight seal when relative movements occur in all three spatial directions, complicating manufacturing and assembly.
Innovation Solution
A connection profile design featuring a sealing leg and plastering leg that form a closed receiving space with a soft, elastic sealing element, and a connecting device between them, allowing for 3D movement and a robust seal through a tongue and groove connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connecting device is used between sealing leg and plastering leg, then structural stability is improved, but 3D movement capability deteriorates
Solution Approach 1:
The connecting device transitions from a rigid structure to a dynamic system with tongue and groove connections that permit relative movement in three spatial directions while maintaining structural integrity. The groove geometry allows controlled articulation between sealing leg and plastering leg.
Solution Approach 2:
A flexible sealing element with high elasticity is introduced between the sealing leg and plastering leg. This flexible component accommodates 3D movements while maintaining the seal, decoupling the structural connection from the sealing function.
2Adaptability or versatility
If a soft, elastic sealing element is used, then 3D movement flexibility is improved, but sealing reliability deteriorates
Solution Approach 1:
The system combines a soft, elastic sealing element with rigid sealing legs and a structured connecting device. This composite approach allows the flexible sealing element to accommodate movements while the rigid structure provides stable anchor points, ensuring both flexibility and sealing reliability.
Solution Approach 2:
The dynamic connecting device with tongue and groove connections controls the movement transmission to the sealing element, ensuring that the elastic material remains effectively engaged with both legs during relative movements, thereby maintaining sealing reliability.
3Adaptability or versatility
If the sealing element is made highly elastic, then movement compensation is improved, but material strength deteriorates
Solution Approach 1:
The highly elastic sealing element is combined with rigid sealing legs and a robust connecting device. The rigid components compensate for the lower strength of the elastic material by providing stable anchor points and structural support, allowing the system to achieve both movement compensation and adequate strength.
Solution Approach 2:
The sealing system is segmented into distinct functional components: highly elastic sealing elements for movement compensation, and rigid sealing legs with tongue and groove connections for structural strength. This segmentation allows each component to be optimized for its specific function.
