Solution Overview

Problem

Existing thermal insulation profiles for fire protection constructions lack variability and cost-effectiveness, as they often require complex production processes and direct heat-conducting contacts between metal profiles, which can lead to inadequate fire resistance and burglary security.

Innovation Solution

A modular thermal insulation profile composed of an insulating strip with channel-shaped depressions and a detachable insert profile made of heat-resistant, non-combustible material, allowing for various configurations and materials to adapt to specific fire protection requirements, reducing heat conduction and enhancing burglary resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a metal insert is completely embedded in plastic to create a one-piece structural unit, then production is simplified, but variability and adaptability to different fire protection requirements are reduced

Engineering Contradiction:
Improveproduction simplicityVSAvoidvariability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The thermal insulation profile is divided into two separate components: an insulating strip and an insert profile. The insert profile can be detached and replaced with different variants (e.g., different materials, geometries, or fire resistance properties) without changing the insulating strip. This segmentation enables high variability and adaptability to different fire protection requirements while maintaining simple production processes for each component separately.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If metal profiles are directly connected through insulating bar fastening lugs, then structural stability is improved, but heat conduction between metal profiles increases

Engineering Contradiction:
Improvestructural stabilityVSAvoidheat conduction
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The insulating strip acts as an intermediary element between the metal profiles. It provides fastening lugs that can be inserted into receiving recesses in the metal profiles, ensuring structural stability, while simultaneously acting as a thermal barrier to prevent direct heat conduction between the metal profiles. The insert profile can be added to enhance this intermediary function without creating direct thermal contacts.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If complex composite elements with metal inserts overmoulded with plastic are produced, then fire resistance is improved, but production complexity and cost increase

Engineering Contradiction:
Improvefire resistanceVSAvoidproduction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of producing complex composite elements through overmoulding, the solution segments the fire protection function into separate components: the insulating strip provides basic insulation and fastening, while the insert profile (made of heat-resistant material) can be added to enhance fire resistance. This modular approach reduces production complexity compared to integrated overmoulded composites while achieving the required fire resistance through material selection and component combination.

Inventive Principle:
Principle #1Segmentation

4Reliability

If receiving geometries are provided in metal profiles for attaching insulating strip, then attachment reliability is improved, but manufacturing complexity of metal profiles increases

Engineering Contradiction:
Improveattachment reliabilityVSAvoidmetal profile complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The receiving recesses are provided only in specific local areas of the metal profiles where attachment is needed, rather than complicating the entire metal profile design. This localized approach ensures reliable attachment of the insulating strip while keeping the overall metal profile manufacturing simple. The insulating strip's fastening lugs are designed to fit into these localized receiving recesses, providing secure attachment without requiring complex metal profile geometries throughout.

Inventive Principle:
Principle #3Local quality
