Insulation Module Triple-Film Packaging for Moisture Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for compressible insulation products, such as fibrous mineral wool, fail to ensure uniform compression and complete protection against moisture, leading to potential degradation of insulating properties during transport and storage, especially when using stretch-wrapping films that do not cover the entire surface and are prone to damage.
Innovation Solution
A module comprising a single row of compressible insulation products wrapped with three films: a first film covering the peripheral surface, a second film wrapping some of the peripheral surface, and a third film covering the ends, ensuring complete coverage and uniform compression in two perpendicular directions, which maintains the product's insulating quality and protects it from moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If insulation products are packaged in a compressed state using a protective wrapper, then transport and storage efficiency is improved, but the product's thickness recovery ability may be degraded
Solution Approach 1:
The patent applies parameter changes by controlling the compression ratio and duration during packaging, and by selecting films with specific elastic properties. The compression is sufficient to reduce bulkiness for transport but controlled to remain within the product's elastic recovery limits, ensuring thickness recovery ability is preserved after unwrapping.
Solution Approach 2:
The patent uses flexible protective films that can apply uniform compression force while allowing the product to maintain its compressed shape during transport. These films provide continuous support during storage and transport, preventing permanent deformation while enabling space-efficient packaging.
2Object-affected harmful factors
If a protective wrapper is used to cover the insulation product, then protection against moisture is improved, but complete coverage is difficult to achieve
Solution Approach 1:
The patent employs a nested packaging structure where an inner protective film directly wraps the insulation product, which is then placed within an outer protective wrapper. This multi-layer nesting ensures that even if one layer has gaps or damage, the product remains protected, achieving complete moisture coverage through redundant protection layers.
Solution Approach 2:
The patent uses composite packaging structures combining different materials with complementary properties - such as water-resistant films, vapor barriers, and mechanical protective layers - to create a packaging system that provides complete and robust moisture protection that no single material could achieve alone.
3Productivity
If stretch-wrapping is used to assemble palletized loads, then loading efficiency is improved, but protection at the ends of products is compromised
Solution Approach 1:
The patent applies preliminary action by pre-wrapping each insulation product or small group of products with protective film before assembling them into palletized loads. This end-protection is established in advance, so when stretch-wrapping is applied for efficient loading, the vulnerable ends are already protected and do not require additional complex packaging during the high-speed palletizing process.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for compact, reproducible stacking and improved protection of insulation products, preserving their thickness recovery ability and insulating properties, even when exposed to external moisture, and facilitates easier unpacking and storage without further precautions.
Implementation Method 1
a first film which wraps each insulation product of the single row in a compressed state of the insulation product... a second film which wraps the single row of insulation products... ensuring uniform compression in two perpendicular directions
Implementation Method 2
a first film which wraps each insulation product of the single row in a compressed state of the insulation product, by covering the peripheral surface... a third film which wraps the single row of insulation products by covering the first and second ends... ensuring complete coverage and protection from moisture

AI summary
A module includes compressible insulation products that each have a longitudinal axis, a peripheral surface, and first and second ends. The module includes a single row of insulation products positioned next to one another along a first direction perpendicular to the longitudinal axes of the insulation products, a first film that wraps each insulation product of the single row in a compressed state by covering the peripheral surface of the insulation product, a second film that wraps the single row of insulation products by covering some of the peripheral surface of the insulation products of the row, and a third film that wraps the single row of insulation products by covering the first and second ends of each insulation product of the row.
