Solution Overview

Problem

Frost-proof outlet fittings struggle to ensure that the rosette attached to the intermediate pipe or outlet housing lies flush against the outer building wall, especially when the pipe is installed at an angle, leading to gaps and inefficiencies in thermal insulation and water drainage.

Innovation Solution

The design incorporates a rosette with a first part that covers the pipe bushing and a second part that is firmly attached to the outlet housing or intermediate pipe, allowing for angular compensation through concave and convex contact areas, enabling the rosette to lie flush against the wall even if the pipe is not perpendicular, using a screw connection for attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the intermediate pipe is installed with a slope for drainage, then water drainage is improved, but the rosette cannot lie flush against the building wall

Engineering Contradiction:
Improvewater drainageVSAvoidrosette alignment with wall
Core Design Contradiction:
ProductivityVSShape

Solution Approach 1:

The rosette is divided into two separate parts: a first rosette part that lies flush against the building wall and a second rosette part that is attached to the intermediate pipe. This segmentation allows each part to fulfill its specific function independently - the first part ensures aesthetic alignment while the second part accommodates the sloped pipe installation for proper drainage

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first rosette part acts as an intermediary element between the building wall and the second rosette part attached to the pipe. It mediates the conflict between the sloped pipe orientation and the requirement for flush wall alignment, allowing the rosette assembly to maintain aesthetic appearance while accommodating the functional drainage slope

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the intermediate pipe protrudes at an angle due to slope installation, then drainage function is achieved, but thermal insulation effectiveness is reduced

Engineering Contradiction:
Improvewater drainageVSAvoidthermal insulation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

By separating the rosette into two parts, the design allows the first part to provide continuous thermal insulation against the wall while the second part attaches to the sloped pipe section, maintaining insulation effectiveness despite the angular protrusion required for drainage

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first rosette part is designed to lie flush against the wall beforehand, creating a thermal insulation barrier that compensates for the potential heat loss from the pipe section that must protrude at an angle for drainage functionality

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
