Solution Overview

Problem

Current methods for filling frames with thermal insulation materials often result in gaps, leading to suboptimal thermal insulation and soundproofing due to difficulties in sizing, insertion, and expansion, with existing foamed materials either being too large, too small, or causing damage during the process.

Innovation Solution

A method involving preparing a foamed molded product smaller than the frame's hollow part, adding moisture with a water-based adhesive for lubrication, and then expanding the material within the frame through additional foaming to ensure a tight fit without gaps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a foamed molded product is used to fill the frame, then thermal insulation performance is improved, but it is difficult to mold and cut to fit the exact size of the empty space

Engineering Contradiction:
Improvethermal insulation performanceVSAvoiddifficulty to mold and cut
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The foamed molded product is prepared in advance with a size slightly smaller than the frame's empty space, allowing easy handling and insertion. The actual size adjustment is then achieved through in-situ foaming expansion after insertion, eliminating the need for precise pre-cutting and molding.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The volume and density parameters of the insulation material are changed dynamically. The material starts with a smaller, more manageable density and volume for easy insertion, then undergoes parameter transformation through foaming expansion to achieve the final desired volume that completely fills the frame space.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the foamed molded product is made too large, then it can fill the frame, but it is difficult to insert and may damage the surface due to friction

Engineering Contradiction:
Improvecomplete filling of frameVSAvoiddifficulty to insert
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The insulation material is prepared in a compressed or smaller-expanded state before insertion, making it easy to handle and insert into the frame without excessive friction. After successful insertion, the material is then allowed to expand to its final volume, ensuring complete filling without insertion difficulties.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the foamed molded product is made too small, then it is easy to insert, but gaps are formed between the product and frame during insertion

Engineering Contradiction:
Improveease of insertionVSAvoidgap formation affecting thermal insulation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The material is inserted in a controlled smaller state to ensure easy placement, then a subsequent foaming expansion process is initiated to increase its volume. This expansion fills any gaps between the material and the frame, ensuring complete coverage and maintaining thermal insulation performance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The insulation material transitions from a static smaller size at insertion to a dynamic expanded state after insertion. The material's volume is not fixed but changes over time through controlled foaming, adapting to completely fill the available space and eliminate gaps.

Inventive Principle:
Principle #15Dynamics

4Quantity of substance

If foamable material is used in excess amount, then the frame is overfilled, but a convex portion is formed requiring frame removal and reconstruction

Engineering Contradiction:
Improveamount of foamable materialVSAvoidwasted cost due to reconstruction
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The foaming expansion process is controlled with feedback mechanisms to monitor the expansion progress. When the material reaches the appropriate volume that completely fills the frame space, the foaming is stopped or controlled, preventing over-expansion and the formation of convex portions that would require costly reconstruction.

Inventive Principle:
Principle #23Feedback

5Ease of manufacture

If foamable material is used in insufficient amount, then the frame is not sufficiently filled, but gaps remain causing cracks and condensation

Engineering Contradiction:
Improvecost efficiencyVSAvoidgap formation causing cracks and condensation
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

Rather than attempting to precisely calculate and apply the exact amount of foamable material needed (which risks insufficiency), the method uses a two-stage approach: insert a smaller amount of material first, then initiate controlled foaming expansion to ensure complete filling. This eliminates the risk of insufficient filling and associated problems like cracks and condensation.

Inventive Principle:
Principle #10Preliminary action
