Profiled Feed-Through Flange for Stable Floor and Ceiling Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bushing arrangements for walls and floors lack a stable and efficient feedthrough solution that ensures secure installation and effective sealing, particularly during the casting process, as they often rely on thick flange elements for stability, which can lead to handling issues and incomplete sealing.
Innovation Solution
A bushing arrangement featuring a flange body that is larger and profiled than the flange element, with a pipe socket for stability and a thermoformed design for weight optimization, allowing for a secure fit and improved sealing with a surface seal like bitumen coating, and enabling modular assembly and sealing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a thick flange element is used to ensure stability during installation, then the stability is improved, but the weight increases and handling becomes more difficult
Solution Approach 1:
The flange is divided into two separate components: a flange element and a flange body. The flange element provides stability during installation, while the flange body can be optimally sized without excessive thickness. This segmentation allows each component to be designed for its specific function, avoiding the need for a single thick flange structure.
Solution Approach 2:
Instead of increasing stability by thickening the flange in one dimension, the solution extends the flange structure in another dimension by adding a separate flange body component. This dimensional approach provides stability through spatial distribution rather than material thickness, reducing weight while maintaining structural integrity.
2Reliability
If a larger flange structure is used to improve sealing overlap with surface seal, then the sealing effectiveness is improved, but the handling during assembly becomes more difficult
Solution Approach 1:
By segmenting the flange into a flange element and a flange body, the larger sealing surface is achieved through the flange body's extended area, while the flange element remains compact for easy handling during assembly. The separation allows the sealing function to be optimized independently from the handling characteristics.
Solution Approach 2:
The flange element acts as an intermediary component that connects the tubular element to the flange body. It provides the necessary stability during installation while the flange body provides the extended sealing surface, mediating between the structural requirements and the sealing requirements without compromising handling.
3Stability of the object's composition
If a monolithic thick flange is used to ensure structural stability, then the stability is improved, but the material usage increases and weight optimization is lost
Solution Approach 1:
The flange structure is segmented into a flange element and a flange body, allowing each component to be optimized for its specific function. The flange element provides structural stability with minimal material, while the flange body provides the necessary sealing surface area. This segmentation eliminates the need for a monolithic thick flange, reducing material usage and weight.
Solution Approach 2:
Different parts of the flange structure have different local qualities: the flange element is designed for structural stability and connection functions, while the flange body is designed for sealing and surface contact. This local differentiation allows material to be distributed efficiently, providing stability where needed without excessive material usage throughout the entire structure.
