Solution Overview

Problem

Existing construction materials like ceramic and glass used in raised access floors face issues with weight increase and material consumption when thickened for mechanical support, leading to handling difficulties and high transport costs, while existing reinforcement methods either fail to adequately address breakage and deflection problems or result in excessive weight and thickness.

Innovation Solution

A construction element featuring a polymer matrix with an embedded mesh of cut threads, where the mesh is completely embedded within the polymer matrix, reducing the overall weight and thickness, and optionally including an insulating layer for fire protection and enhanced mechanical properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the thickness of ceramic or glass plates is increased to avoid breakage and deflection in raised access floors, then the mechanical strength and stability are improved, but the weight increases significantly and handling becomes difficult

Engineering Contradiction:
Improvemechanical strengthVSAvoidweight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The invention applies composite materials by combining ceramic or glass plates with a polymer matrix containing an embedded mesh structure. This composite construction provides the necessary mechanical strength and deflection resistance while maintaining a reduced thickness and weight compared to solid thick plates, thus resolving the contradiction between strength and weight.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention applies local quality by concentrating reinforcement only where needed - the polymer matrix with embedded mesh is applied to the back of the plate at specific locations rather than uniformly thickening the entire plate. This localized reinforcement provides adequate mechanical strength while minimizing weight increase.

Inventive Principle:
Principle #3Local quality

2Strength

If the thickness of plates is increased to support loads and prevent deflection, then the mechanical performance is improved, but the material consumption and transport costs increase

Engineering Contradiction:
Improveload-bearing capacityVSAvoidmaterial consumption
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The composite structure of ceramic/glass plate combined with polymer matrix and embedded mesh provides high load-bearing capacity with minimal material consumption. The mesh structure within the polymer matrix efficiently distributes loads, allowing the use of thinner plates that consume less material while maintaining required strength.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention changes the structural parameters by introducing a mesh pattern within the polymer matrix, which optimizes the strength-to-material-ratio. This parameter change allows achieving the required load-bearing capacity with significantly reduced material consumption compared to solid thick plates.

Inventive Principle:
Principle #35Parameter changes

3Strength

If existing reinforcement methods such as calcium sulphate or chipboard panels are used, then the strength is improved, but the weight and thickness increase excessively

Engineering Contradiction:
Improvemechanical strengthVSAvoidthickness
Core Design Contradiction:
StrengthVSLength of stationary object

Solution Approach 1:

The invention uses a thin polymer matrix film with an embedded mesh structure as the reinforcement layer. This thin-film approach provides adequate mechanical strength while maintaining minimal thickness, unlike bulk materials such as calcium sulphate or chipboard panels that require significant thickness to achieve comparable strength.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The combination of polymer matrix and embedded mesh creates a high-strength composite material that achieves the required mechanical performance in a thin profile. This composite structure is more efficient than traditional reinforcement materials, providing equivalent or superior strength with reduced thickness.

Inventive Principle:
Principle #40Composite materials

4Ease of manufacture

If the mesh is not completely embedded in the polymer matrix, then the manufacturing process is simpler, but the mechanical properties and breakage resistance are insufficient

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidbreakage resistance
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The mesh is pre-positioned and completely embedded within the polymer matrix before the final curing process. This preliminary embedding action ensures optimal mechanical properties and breakage resistance while maintaining manufacturing efficiency, as the complete embedding is achieved in a single process step rather than requiring multiple operations.

Inventive Principle:
Principle #10Preliminary action
