Solution Overview

Problem

Existing mix dispensers for stone or ceramic slabs face issues with the high cost and short working life of fabric-reinforced elastomeric conveyor belts, which are prone to premature deterioration due to solvent vapors, leading to frequent maintenance stoppages and increased production costs.

Innovation Solution

The use of a meshwork conveyor made of metallic material resistant to solvents, such as metal meshwork lined with a thin protective plastic film, replaces the traditional elastomeric conveyor belt, ensuring durability and reducing maintenance needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fabric-reinforced elastomeric conveyor belt is used, then the conveyor provides good flexibility and material handling, but it deteriorates prematurely due to solvent vapors, leading to frequent maintenance

Engineering Contradiction:
Improveconveyor belt durabilityVSAvoidconveyor belt working life
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies composite materials by combining a metal meshwork structure with a plastic coating layer. The metal meshwork provides mechanical strength and solvent resistance, while the plastic coating provides flexibility and material handling properties. This composite structure resolves the contradiction by achieving both durability against solvent vapors and operational flexibility.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the material parameters of the conveyor belt from organic elastomeric material to inorganic metal meshwork with plastic coating. This parameter change transforms the conveyor belt's chemical resistance properties, making it immune to solvent vapor degradation while maintaining operational characteristics.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If a fabric-reinforced elastomeric conveyor belt is used, then the conveyor provides adequate transport function, but the cost increases due to frequent replacement and maintenance stoppages

Engineering Contradiction:
Improveproduction continuityVSAvoidmaintenance downtime
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent employs a metal meshwork conveyor that significantly extends service life compared to traditional elastomeric belts. Although the initial investment may be higher, the extended operational life between replacements reduces overall maintenance frequency and production downtime, improving productivity over time.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Strength

If a fabric-reinforced elastomeric conveyor belt is used, then the conveyor provides flexibility, but mechanical strength is insufficient leading to premature failure

Engineering Contradiction:
Improveconveyor belt strengthVSAvoidconveyor belt reliability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The metal meshwork provides superior mechanical strength compared to fabric-reinforced elastomeric materials. The three-dimensional wire structure offers inherent rigidity and load-bearing capacity while the plastic coating maintains flexibility. This composite approach simultaneously improves strength and reliability.

Inventive Principle:
Principle #40Composite materials

AI summary

A mix dispenser (14) comprises a hopper (24) with a top opening (26) for filling the hopper with a predetermined amount of mix and a bottom opening (28). The dispenser comprises a conveyor (30) which forms the bottom of said hopper (24) and is designed to extract the mix from the hopper (24) and convey it towards an end from where it falls into a mould. The dispenser is characterized in that said conveyor (30) comprises a supporting meshwork (32) made of a material resistant to the vapours of solvents such as styrene and operated by an electric motor (34). Furthermore a plant comprising such as dispenser is also described.
