Solution Overview

Problem

The existing mounting systems for attaching objects to smooth or high-quality surfaces, such as tiles and natural stone, face issues with adhesive hold and curing time, with the liquid- and gas-permeable element's pore design and sintering process influencing bonding quality and duration.

Innovation Solution

Optimizing the design of the liquid- and gas-permeable element's pore structure and incorporating a fibrous moisturizer to enhance moisture transport and adhesive bonding, with specific dimensions and thicknesses for the element and adhesive layer for improved bonding speed and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the pores in the liquid- and gas-permeable element are made larger to improve gas and moisture transport, then the curing speed increases, but the adhesive penetration into the pores increases which weakens the bond

Engineering Contradiction:
Improvecuring speedVSAvoidadhesive bond strength
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The element is designed with a gradient pore structure where the pore size varies through the thickness of the element. The outer surfaces have smaller pores to prevent adhesive penetration and maintain bond strength, while the inner region has larger pores to facilitate efficient gas and moisture transport for faster curing. This local variation in pore quality resolves the contradiction between curing speed and bond strength.

Inventive Principle:
Principle #3Local quality

2Strength

If the pores in the element are made smaller to prevent adhesive penetration, then the bond strength improves, but the gas and moisture transport becomes very slow extending the curing time

Engineering Contradiction:
Improveadhesive bond strengthVSAvoidcuring time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The element features a differentiated pore structure where small pores are concentrated at the outer surfaces adjacent to the adhesive layer to prevent adhesive penetration and ensure strong bonding. Larger pores are positioned in the inner region of the element to provide efficient transport pathways for gas and moisture. This spatial differentiation of pore sizes resolves the contradiction between bond strength and curing time.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The pore structure is designed with vertical dimensionality, creating distinct pore zones at different depths within the element. The pore size transitions from small at the adhesive-facing surface to large in the interior, adding a depth dimension to the pore architecture. This dimensional approach allows simultaneous optimization of both bonding (at the surface) and curing (in the interior).

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Stability of the object's composition

If the adhesive gap is increased to improve adhesive distribution, then the bonding uniformity improves, but the amount of adhesive required increases and the setting time extends

Engineering Contradiction:
Improvebonding uniformityVSAvoidsetting time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The element utilizes its porous structure to wick and distribute adhesive uniformly across its surface through capillary action. The pore network acts as a distribution system that spreads the adhesive evenly throughout the gap region without requiring a large adhesive volume. This porous distribution mechanism achieves bonding uniformity while minimizing adhesive consumption and maintaining reasonable setting times.

Inventive Principle:
Principle #31Porous materials

4Ease of manufacture

If the element is made thinner to reduce material usage, then the manufacturing cost decreases, but the mechanical stability and adhesive bond strength are reduced

Engineering Contradiction:
Improvemanufacturing costVSAvoidadhesive bond strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The element employs an optimized porous structure with controlled porosity and pore interconnectivity that provides high mechanical strength relative to its thin profile. The porous network acts as a reinforcement structure that maintains structural integrity and bonding capacity even at reduced thickness. This allows the element to be made thinner for cost reduction while preserving the necessary mechanical stability and adhesive bond strength through the engineered pore architecture.

Inventive Principle:
Principle #31Porous materials

AI summary

The invention relates to an optimization of a mounting system that is attached to a high-quality wall by means of adhesive bonding. A liquid- and gas-permeable element is bonded to the wall using a fixing ring. The actual aerobic adhesive is then injected into a cavity. By optimizing the mounting system, a ratio of the specific gravity of the "airy" element to the specific gravity of the element's material can be determined. In a further embodiment, a flow rate for the liquid- and gas-permeable element and layer thicknesses for the adhesive and the element can be specified. In a further embodiment of the invention, a fibrous moisture carrier is arranged in the mounting system.
