Solution Overview

Problem

Traditional terrazzo compositions require multiple steps and materials, making them complex and time-consuming to produce, while also lacking in meeting specific strength and weight requirements for applications like underlayment and decorative surfaces.

Innovation Solution

A lightweight terrazzo composition comprising a resin component, a hardener component, and an aggregate component, with specific ratios and types of epoxy resin, hardeners, and bead mixtures, which are blended and applied to achieve high tensile and compressive strengths, Shore D Hardness, and weight specifications, meeting MIL-PRF-3135H standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional terrazzo compositions are used with multiple steps and materials, then the surface can be created, but the production process becomes complex and time-consuming

Engineering Contradiction:

Improveproduction process simplicityVSAvoidnumber of steps and materials

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple traditional terrazzo layers (underlayment, sealer, color coat, decorative chips, top coat) into a single integrated composition that is applied in one step. This merging of functions eliminates the need for separate application steps while maintaining all necessary protective and decorative properties.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single terrazzo composition serves multiple functions simultaneously: it provides underlayment support, sealing, coloration, decorative elements, and top coat protection. This multi-functionality is achieved by incorporating all necessary components into one unified mixture that cures to form a complete surface system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If traditional terrazzo compositions are used, then the surface can be created, but it takes more time to produce

Engineering Contradiction:

Improveproduction speedVSAvoidcuring and application time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The composition is pre-formulated with all necessary components (resin, hardener, aggregates, decorative chips) already mixed and ready for application. This preliminary preparation eliminates the need for on-site mixing and multiple application steps, significantly reducing the time required to produce the final surface.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The single-application composition allows continuous work without interruption for multiple separate applications. The composition is designed to be applied in one continuous operation and cured to form the complete surface, eliminating the time losses associated with multiple separate application cycles.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If conventional terrazzo compositions are used, then the surface can be created, but it fails to meet specific strength and weight requirements

Engineering Contradiction:

Improvestrength and weight specificationsVSAvoidcontrol of mechanical properties

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent specifies precise parameter ranges for the composition components: resin content (32-37 wt%), hardener content (12.4-12.6 wt%), and aggregate content (50-56 wt%). By controlling these parameters within defined ranges, the composition reliably achieves the required tensile strength (8500-8900 psi), compressive strength (2600-3000 psi), and weight (0.60-0.76 lbs/sq ft at 0.25 inch thickness).

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The composition uses a carefully selected composite of materials with specific properties: epoxy resin for bonding, polyamine hardener for curing, and a mix of aggregates (glass beads, sand, decorative chips) for strength and aesthetics. This composite material system is designed to meet or exceed military specifications while providing controlled mechanical properties.

Inventive Principle:

Principle #40Composite materials
