Solution Overview

Problem

Existing fibrous insulation materials for building structures, such as mineral wool batts, require multiple sizes to fit varying distances between elongated members, leading to high waste and storage challenges due to their rigidity and limited compressibility, making them costly and less available in retail stores.

Innovation Solution

Incorporating a flexible zone on one side and a trim portion on the opposite side of the insulation element, made by compressing and reducing fibre bonding during manufacturing, allowing for compression and easy trimming to fit various distances without compromising thermal insulation properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If insulation elements are manufactured in many different sizes to fit varying distances between elongated members, then the insulation elements can fit correctly in the cavities, but the storage space required increases significantly and waste material increases

Engineering Contradiction:
Improvefit rangeVSAvoidstorage space
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The insulation element is divided into two distinct zones: a rigid zone that maintains structural integrity and a flexible zone that can be compressed to adapt to varying cavity distances. This segmentation allows a single product to serve multiple size requirements without needing multiple inventory variants.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flexible zone is created by changing the physical parameters of the insulation material in that region during manufacturing - specifically by compressing the edge region and reducing fibre bonding. This creates a zone with different compressibility characteristics that enables the element to adapt to different cavity sizes within a single product design.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If insulation elements are compressed to fit smaller cavities, then they can accommodate varying distances, but the insulation elements may bend out of the cavity if too compressed

Engineering Contradiction:
ImprovecompressibilityVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

By dividing the insulation element into rigid and flexible zones, the patent ensures that compression occurs only in the flexible zone while the rigid zone maintains structural support. This prevents the entire element from bending out of the cavity even when highly compressed to fit small spaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the insulation element are given different mechanical properties - the rigid zone maintains high structural stability while the flexible zone is engineered for high compressibility. This local differentiation of material properties allows the element to be compressed without compromising overall structural integrity.

Inventive Principle:
Principle #3Local quality

3Temperature

If fibrous insulation material is used to meet thermal insulation requirements, then thermal insulation performance is improved, but the material requires high storage space and generates high waste when cut to size

Engineering Contradiction:
Improvethermal insulationVSAvoidwaste material
Core Design Contradiction:
TemperatureVSLoss of substance

Solution Approach 1:

The patent modifies the fibre bonding parameters in the flexible zone during manufacturing to create compressibility while maintaining thermal insulation performance. This allows the single element to be compressed and trimmed to fit various cavity sizes without generating significant waste, as the flexible zone can be compressed to accommodate size variations.

Inventive Principle:
Principle #35Parameter changes

4Adaptability or versatility

If multiple sizes of insulation slabs are kept in store to serve DIY customers, then customer needs are met, but the storage space consumption becomes unacceptable for retailers

Engineering Contradiction:
Improveproduct rangeVSAvoidretail storage
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The insulation element is designed as a universal product that can serve multiple functions and size requirements through its dual-zone construction. The flexible zone enables the same product to adapt to different cavity distances, making it a multi-functional solution that replaces the need for multiple specialized products in retail inventory.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The segmentation into rigid and flexible zones creates a product that inherently provides size adaptability, allowing retailers to stock fewer variants while still meeting diverse customer needs for different cavity dimensions.

Inventive Principle:
Principle #1Segmentation
