Solution Overview

Problem

Mounting insulation frames and windows in inclined roof structures is challenging due to mismatched dimensions and non-perpendicular angles between battens and counter battens, leading to difficulties or impossibility without damaging the insulation frame or requiring modifications.

Innovation Solution

Incorporating grooves on the insulation members made of resilient materials, allowing transient deformation during mounting to create space for the window frame, which re-expands to maintain a tight fit without damage, and using a combination of compressible and dimensionally stable materials for enhanced adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the insulation frame is made rigid to maintain structural stability and insulation properties, then the structural strength and insulation performance are improved, but the difficulty of mounting increases and damage occurs when the roof structure dimensions do not match

Engineering Contradiction:
Improvestructural strengthVSAvoidease of mounting
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The insulation frame is divided into rigid portions (for structural strength) and resilient portions with grooves (for adaptability). The grooves segment the rigid structure, allowing localized deformation while maintaining overall structural integrity and insulation properties.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insulation frame incorporates portions with changed physical parameters - specifically, regions with grooves that have different mechanical properties (resilient) compared to the solid rigid portions. This allows the frame to adapt to dimensional variations in roof structures while maintaining structural strength.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the insulation frame dimensions are precisely matched to the roof structure, then the fit and insulation performance are improved, but the adaptability to manufacturing tolerances and structural variations deteriorates

Engineering Contradiction:
Improvedimensional precisionVSAvoidadaptability to roof structure variations
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The insulation frame transitions from a completely static rigid structure to a dynamic structure with resilient portions that can deform. The grooves enable the frame to adapt dynamically to dimensional variations in the roof structure, accommodating manufacturing tolerances and structural deviations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different portions of the insulation frame have different properties - rigid portions maintain precise dimensions for structural strength, while portions with grooves provide local adaptability. This local quality differentiation allows the frame to simultaneously achieve precision and adaptability.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If the insulation frame is made compressible to ease installation, then the ease of mounting is improved, but the insulation performance and structural stability may deteriorate

Engineering Contradiction:
Improveease of installationVSAvoidinsulation performance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The insulation frame is segmented into compressible portions (with grooves for ease of installation) and rigid insulated portions (for maintaining insulation performance). The grooves allow localized compression during installation while the solid rigid portions maintain their insulation properties and structural stability.

Inventive Principle:
Principle #1Segmentation
