Solution Overview

Problem

Current methods for constructing distribution mattresses require extensive ground preparation, including leveling and soil improvement, which are time-consuming and costly, especially when dealing with loose or compressible materials, and often necessitate thick mattresses to handle high stresses from constructions like industrial pavings.

Innovation Solution

Incorporating a mesh reinforcement during the compacting process of the distribution mattress material, such as metallic, composite, or plastic lattice mesh, to enhance load-bearing capabilities while maintaining homogeneity and reducing thickness, allowing for increased spacing of foundation elements like columns or piles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the thickness of the distribution mattress is increased to handle high stresses from industrial pavings, then the bearing capacity is improved, but the material costs and construction time increase

Engineering Contradiction:
Improvebearing capacityVSAvoidmaterial quantity
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The patent combines compacted material with a mesh reinforcement layer to create a composite structure. The mesh reinforcement (metallic, composite, or plastic) provides additional tensile strength and load distribution capability, allowing the mattress to handle high industrial stresses with reduced overall thickness and material quantity while maintaining bearing capacity

Inventive Principle:
Principle #40Composite materials

2Strength

If the thickness of the distribution mattress is increased to handle high stresses, then the bearing capacity is improved, but the construction time increases

Engineering Contradiction:
Improvebearing capacityVSAvoidconstruction time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The mesh reinforcement layer is integrated into the compacted material mattress during construction. This composite approach accelerates the construction process by providing immediate structural enhancement without requiring additional time-consuming steps, as the mesh is placed and compacted together in a single operational sequence

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the structural parameters of the mattress by incorporating a reinforcement mesh with specific geometric characteristics (mesh size, wire diameter, pattern). This parameter modification enables the mattress to achieve required bearing capacity with optimized thickness, reducing both material quantity and construction time while maintaining or improving strength

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If ground improvement techniques are used to modify loose or compressible materials, then the stability is improved, but the construction time and costs increase

Engineering Contradiction:
Improveground stabilityVSAvoidpreparation time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The mesh reinforcement creates a composite ground structure that stabilizes loose or compressible materials without requiring extensive ground improvement techniques. The mesh provides immediate structural stability by distributing loads and preventing material displacement, eliminating time-consuming soil treatment processes while maintaining ground stability

Inventive Principle:
Principle #40Composite materials

4Strength

If a mesh reinforcement is introduced during compacting, then the load-bearing capability is enhanced, but the device complexity increases

Engineering Contradiction:
Improveload-bearing capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The reinforcement is introduced as a separate mesh layer that is integrated during the compacting process. This segmentation allows the mesh to be manufactured independently using standard industrial processes, then incorporated into the mattress without requiring complex integrated manufacturing systems, thus enhancing load-bearing capability while minimizing device complexity

Inventive Principle:
Principle #1Segmentation
