Solution Overview

Problem

Existing methods for casting pipes into concrete structures, such as walls or floors, face challenges in accommodating angled pipe installations and ensuring easy access for cable routing and sealing, often requiring complex shapes or additional components that increase effort and complexity.

Innovation Solution

The use of a hollow body with a flange, placed on the formwork before casting, which creates a cavity at the axial end of the pipe element, allowing for oblique pipe installation and easy access for cable routing and sealing, while providing stability and a surface for surface sealing, using a combination of a tubular element and a hollow body assembled as separate parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a pipe element is cast directly into the wall or floor element at an angle, then cable routing flexibility is improved, but the pipe end shape becomes elliptical requiring additional adapted covers and effort

Engineering Contradiction:
Improvecable routing flexibilityVSAvoidpipe end coverage complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The feedthrough is divided into two separate components: the tubular element and the hollow body. The hollow body serves as a mounting structure that holds the tubular element at an angle while providing a flat, circular end surface that simplifies cable routing and eliminates the need for elliptical covers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hollow body acts as an intermediary structure between the wall/floor element and the tubular element. It provides a flat mounting surface for the tubular element while maintaining the angled orientation, thus solving both the cable routing flexibility and the simplified end coverage requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a foam body is placed on the pipe element for cable routing, then accessibility is improved, but additional work is required to remove it and clean connections

Engineering Contradiction:
Improvecable routing accessibilityVSAvoidtime for removal and cleaning
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The hollow body is pre-installed on the formwork before casting, creating a permanent cavity structure. This eliminates the need for temporary foam bodies that require removal and cleaning, as the hollow body itself provides the necessary accessibility and space for cable routing operations.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple additional components are used to achieve angled pipe installation and accessibility, then functionality is improved, but device complexity increases

Engineering Contradiction:
Improveangled installation capabilityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hollow body combines multiple functions into a single component: it serves as a mounting structure for the tubular element, provides a flat end surface for simplified coverage, creates a cavity for accessibility, and maintains the angled orientation. This integration reduces the total number of components required.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hollow body is designed as a universal mounting structure that can accommodate the tubular element at various angles while providing consistent benefits: flat end surface, cavity creation, and simplified cable routing. This multi-functional design eliminates the need for angle-specific adapters or multiple specialized components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
