Solution Overview

Problem

Existing floor duct systems lack effective solutions for angled pipe routing and safety during construction phases, particularly in scenarios where there is a risk of accidents from uneven surfaces and delayed pipe system construction.

Innovation Solution

A floor duct system featuring a hollow body with an insert that provides a recess for angled pipe routing and includes a hard plastic insert with a stepped design for step protection, which can withstand significant surface loads and includes features for drainage and assembly aids like a spirit level and breakable sections for easy removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a floor penetration is cast into a base plate together with a pipe element, then the pipe system can be installed through the foundation slab, but the pipe element creates a protruding surface that poses safety risks during construction

Engineering Contradiction:
Improvesafety during constructionVSAvoidaccident risk from uneven surface
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

An insert element is introduced as an intermediary component that temporarily covers the hollow body of the floor penetration. This insert with its upper cover plate creates a flush surface with the base plate top surface, eliminating the hazard of protruding pipe elements during construction while allowing safe worker movement.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the pipe element extends through the foundation slab, then wastewater can be conveyed outside the building, but horizontal offsets require complex pipe routing solutions

Engineering Contradiction:
Improvepipe routing flexibilityVSAvoidpipe system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hollow body is pre-formed as part of the floor penetration structure during base plate casting. This preliminary preparation creates a recess space that later accommodates angled pipe guides, allowing horizontal offsets to be compensated without requiring complex pipe routing solutions during subsequent installation.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the hollow body recess is larger than the pipe element outer diameter, then angled pipe guides can compensate for offsets, but the larger opening increases exposure to contaminants during construction

Engineering Contradiction:
Improveangled pipe routing capabilityVSAvoidcontaminant exposure risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The insert serves as a temporary intermediary cover that closes the hollow body opening during construction phases. This allows the hollow body to maintain its larger recess dimension for future angled pipe routing while the insert prevents contaminant entry into the pipe system during the construction period.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If the insert is designed to withstand high surface loads for safety, then worker safety is improved, but the insert material and design become more complex

Engineering Contradiction:
Improvestep protection capabilityVSAvoidinsert structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The insert is manufactured from rigid plastic material that combines sufficient load-bearing capacity with ease of formation. This material choice allows the insert to withstand high surface loads for worker safety while maintaining a relatively simple single-piece construction without requiring complex multi-material composite structures.

Inventive Principle:
Principle #40Composite materials
