Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conical attachment bases for roof openings, particularly for smoke and heat extraction systems, are expensive and complex to assemble, requiring specialized tools and space due to their finished frame structure and large dimensions.

Innovation Solution

The attachment base is designed as a kit of individual linear longitudinal profiles with square to rectangular contours and corner connectors, allowing for quick and easy assembly via plug connections without specialized tools, significantly reducing manufacturing, transport, and storage costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conical attachment bases are designed as finished frame structures with sloping side walls, then they provide good aerodynamic parameters for gas and smoke streams, but they require large space for storage and transport

Engineering Contradiction:

Improveaerodynamic performanceVSAvoidstorage and transport space

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

The attachment base is divided into separate components (side wall elements and corner connectors) that can be stored and transported independently in a compact state, then assembled on-site to form the complete conical structure with optimal aerodynamic properties

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If conical attachment bases are manufactured as finished frame structures, then they provide structural integrity, but they are expensive and complex to manufacture

Engineering Contradiction:

Improvestructural integrityVSAvoidmanufacturing complexity and cost

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The structure is segmented into standardized side wall elements and corner connectors that can be manufactured independently using simpler processes, then assembled to create the complete structure with maintained structural integrity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The corner connectors are designed as universal components that can connect multiple side wall elements at different angles and positions, reducing the variety of specialized parts needed and simplifying manufacturing

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If conical attachment bases are assembled as finished frame structures, then they ensure precise alignment, but they require complicated assembly procedures with specialized tools

Engineering Contradiction:

Improvealignment precisionVSAvoidassembly simplicity

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

Alignment features and connection interfaces are pre-formed on the side wall elements and corner connectors during manufacturing, so that on-site assembly requires only simple connection operations without specialized alignment tools or procedures

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If conical attachment bases are designed as finished frame structures, then they provide complete functionality, but they require large space and special handling during transport and storage

Engineering Contradiction:

Improvefunctional completenessVSAvoidtransport and storage space

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The complete attachment base is segmented into compact modules (side wall elements and corner connectors) that occupy minimal storage and transport space, yet can be assembled on-site to provide the complete conical structure with all necessary functional properties

Inventive Principle:

Principle #1Segmentation

AI summary

The base (10) has a rectangular shaped rotating base frame (11) comprising a top base element and a foot side. The foot side comprises a foot-side aperture (13) that is formed in diagonally directed wall surfaces (14-17). Side walls are formed from longitudinal sections (18-21) to a rectangular contour, and the corner regions are provided with the longitudinal sections by corner connectors (40, 42) in the wall surfaces. The corner regions are arranged against the corner connectors. The base frame is formed by plug connections from the longitudinal sections and the corner connectors.
