Solution Overview

Problem

Conventional packaging methods for compressible insulating products, such as fibrous insulation, fail to adequately protect the products from humidity and environmental damage, leading to degradation of their insulating properties during transport and storage, especially when the products are compressed and wrapped in a way that leaves ends exposed.

Innovation Solution

A packaging system comprising a stack of modules, where each module consists of a row of insulating products wrapped in a first film and then covered by a second film, forming a sleeve, and the entire stack is encased in a cover that seals all faces except one, ensuring complete protection against humidity and external contaminants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If insulating products are packaged in a compressed state with a protective envelope, then transport and storage space is reduced, but the product's thickness recovery capacity is degraded

Engineering Contradiction:

Improvepackage volumeVSAvoidthickness recovery capacity

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The packaging system is divided into multiple independent layers: an inner protective envelope (first film) that directly contacts and protects each insulating product, and an outer packaging structure (second film and board) that provides mechanical support during transport. This segmentation allows the inner envelope to maintain product integrity while the outer structure provides compression resistance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A rigid board is positioned between stacked packages to provide beforehand cushioning and support. This board prevents excessive compression of the insulating products during storage and transport, ensuring that the products can recover their thickness when unpacked, while still allowing for compact packaging.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Object-affected harmful factors

If a protective envelope is used to maintain products in roll state, then product protection is improved, but complete protection against humidity is insufficient

Engineering Contradiction:

Improveproduct protectionVSAvoidhumidity protection

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The packaging uses a composite structure combining different materials with complementary properties: the first film (protective envelope) provides product protection and shape maintenance, while the second film and rigid board layers provide enhanced humidity barrier properties. This composite approach ensures both mechanical protection and complete humidity protection.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The packaging employs a nested structure where the first film (inner envelope) is placed inside the second film (outer envelope), which in turn is positioned between rigid boards. This nested arrangement ensures that the insulating product is protected by multiple barrier layers against humidity from all directions, including the previously exposed ends.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Productivity

If rolls are stacked and wrapped together, then transport efficiency is improved, but water infiltration risk increases at exposed ends

Engineering Contradiction:

Improvetransport efficiencyVSAvoidwater infiltration risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The second film is used as a flexible shell that completely envelops the stack of insulating products, sealing all exposed ends and surfaces. This flexible film creates a continuous barrier that prevents water infiltration while allowing the packages to be efficiently stacked and transported as a unified load.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

This package (8) comprises compressible insulating products (1), each insulating product (1) having a longitudinal axis (X1), a peripheral surface and first and second ends. The package (8) comprises a stack (6) of at least two modules (5), where each module (5) comprises one row of insulating products (1) arranged side by side in a first direction (D1). The modules (5) of the stack (6) are superimposed in a second direction (D2) perpendicular to the longitudinal axes (X1) of the insulating products (1) and to the first direction (D1). The package (8) also comprises a cover (7) which encloses the stack (6) by covering five faces (62, 63, 64, 66, 68) of the stack, including the two end faces (62, 64) of the stack, formed by the ends of the insulating products (1) and at least the periphery of the sixth face (61) of the stack.
