Solution Overview

Problem

Existing methods for bonding insulating plates in building insulation often result in incomplete adhesive layers with air inclusions, which fail to meet the requirements for thermal insulation and fire barriers due to manual application techniques that leave grooves or furrows, leading to cavities and uneven surfaces.

Innovation Solution

A method involving full-surface coating of insulating boards with an adhesive mass on-site, followed by vibratory driving to expel air pockets and ensure a continuous, homogeneous adhesive layer, which can be applied to either the board or substrate, minimizing voids and enhancing bonding quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If adhesive is applied manually using a notched trowel, then application speed is improved, but adhesive layer homogeneity deteriorates due to grooves and air pockets

Engineering Contradiction:
Improveapplication speedVSAvoidadhesive layer homogeneity
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies mechanical vibration through a plate attached to the insulation board, which generates vibrations that propagate into the adhesive layer. This vibration causes the adhesive to flow and fill the grooves created by the notched trowel, expelling air pockets and creating a homogeneous adhesive layer without sacrificing application speed

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The patent changes the physical state of the adhesive by applying vibration, which temporarily alters the adhesive's flow characteristics. The vibration energy transforms the adhesive from a static state to a dynamic flowing state, allowing it to self-level and fill voids, then returns to its original state once bonding occurs

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If adhesive is applied in grooves or furrows to enable quick positioning, then ease of operation is improved, but bonding reliability deteriorates due to incomplete filling and air inclusions

Engineering Contradiction:
Improvepositioning easeVSAvoidbonding continuity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The vibration device attached to the insulation board generates mechanical vibrations that propagate through the board into the adhesive layer. This vibration causes the adhesive to flow dynamically, completely filling the grooves and eliminating air pockets, thereby ensuring continuous and reliable bonding while maintaining ease of positioning

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The patent converts the harmful effect of grooves (which create air pockets and incomplete filling) into a beneficial process. The grooves created by the notched trowel serve as channels for adhesive flow during vibration, allowing the adhesive to self-distribute and fill all voids, transforming the initial defect into a mechanism for achieving homogeneous bonding

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
