Building Feedthrough Layout for Outdoor Utility Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building installation methods face challenges in providing efficient and cost-effective outdoor access for utilities like electricity, water, and data connections, particularly in installations that require large casing pipe diameters and complex post-construction modifications.
Innovation Solution
A building installation arrangement featuring a bushing with a casting body integrated into a wall or floor element, connected to a casing pipe that extends into the ground, allowing media lines to exit the building and provide outdoor consumer connections without requiring extensive post-construction drilling or modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional building installation methods are used with post-construction drilling and modifications, then installation flexibility is maintained, but installation complexity and cost increase significantly
Solution Approach 1:
The casting body is integrated into the wall or floor element during the construction phase, with casing pipes pre-positioned and extending through the structure. Media lines are laid through these pipes before the building is completed, eliminating the need for post-construction drilling and modifications. This preliminary action resolves the contradiction by simplifying installation while reducing post-construction complexity.
2Adaptability or versatility
If large casing pipe diameters are used for outdoor utility access, then future expansion capability is improved, but installation difficulty and cost increase
Solution Approach 1:
The system divides the utility access into separate casing pipes that can be individually sized and positioned within the casting body. Each casing pipe can be optimized for specific media lines, allowing large diameters where needed for future expansion while maintaining manageable installation through the modular casting body structure.
Solution Approach 2:
Multiple casing pipes with adequate diameters are pre-installed in the casting body during construction, providing future expansion capability without requiring difficult post-construction modifications. The preliminary placement of appropriately sized pipes resolves the contradiction between expansion capability and installation ease.
3Ease of operation
If media lines exit the building through the casting body to outdoor connections, then outdoor utility accessibility is improved, but building envelope integrity is compromised
Solution Approach 1:
The casing pipes are nested within the casting body, which itself is integrated into the wall or floor element. Media lines are nested within the casing pipes, creating a hierarchical protection system. This nested structure provides outdoor utility accessibility while maintaining building envelope integrity through multiple protective layers.
Solution Approach 2:
The casting body acts as an intermediary structure between the building interior and exterior, providing sealed passages through the building envelope. The casing pipes serve as intermediate conduits that protect media lines while passing through the envelope. This intermediary approach resolves the contradiction by enabling outdoor accessibility while preserving envelope integrity.
