Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hollow chamber seals are difficult to bend, making them unsuitable for sealing building corners, polygonal facades, or sawtooth floor plans, and the existing corner pieces are often complex and prone to weak points during manufacturing and installation.
Innovation Solution
A sealing corner element with a one-sided recessed wall and plastically deformable stabilizing elements allows for flexible bending and stabilization, enabling use in various angles and ensuring a good seal, while maintaining dimensional stability and easy connection to hollow chamber seals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hollow chamber seals are used for sealing facade elements, then good sealing performance is achieved, but they become difficult to bend and unsuitable for complex corners
Solution Approach 1:
The sealing corner element is divided into distinct functional regions: a first side with a wall shaped to match hollow chamber seals for sealing contact, and a second side without walls in bending regions to enable flexibility. This segmentation allows different parts of the same component to have opposite properties - rigidity where sealing is needed and flexibility where adaptation is needed.
Solution Approach 2:
The sealing corner element exhibits local quality by having walls only on the first side where sealing contact is required, while the second side remains wall-free in bending regions. This localized structural differentiation enables the component to provide both sealing functionality and bendability in appropriate locations simultaneously.
2Stability of the object's composition
If corner pieces are manufactured individually with walls on both sides, then structural stability is achieved, but manufacturing complexity increases and sealing reliability decreases due to cutting and gluing
Solution Approach 1:
The invention extracts the wall structure from the bending regions on the second side, leaving only the essential sealing wall on the first side. This extraction eliminates the need for complex cutting and gluing operations while maintaining structural stability where needed, thereby reducing manufacturing complexity.
Solution Approach 2:
The sealing corner element is designed with pre-formed geometric shapes that allow direct insertion and bending without requiring post-manufacturing operations like cutting or gluing. The stabilizing elements are pre-positioned to maintain dimensional stability during installation, eliminating complex assembly steps.
3Stability of the object's composition
If walls are present on both sides of the sealing corner element, then dimensional stability is achieved, but flexibility for various bending angles is reduced
Solution Approach 1:
The sealing corner element employs asymmetric design with walls present only on the first side and absent on the second side in bending regions. This asymmetric configuration provides dimensional stability through the sealed hollow chamber on the first side while enabling flexibility and various bending angles on the wall-free second side.
Solution Approach 2:
The invention resolves the stability-flexibility contradiction by transitioning to a different dimensional configuration - creating a one-sided wall structure that allows the component to bend in multiple directions and angles without requiring walls on all sides, thus achieving flexibility in three-dimensional space while maintaining stability.
