Solution Overview

Problem

Conventional whey draining machines experience issues such as stick-slip phenomenon, belt wear, and reduced capacity due to friction and tension, along with challenges in cleaning the belt support structure.

Innovation Solution

A support structure featuring a metal beam with a plastic slide plate that allows the whey draining belt to slide over it, reducing friction and facilitating easy cleaning-in-place by using sliding friction and notches for pin engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a metal support structure is used for the whey draining belt, then the structural strength is improved, but friction between the belt and support structure causes stick-slip phenomenon and belt wear

Engineering Contradiction:
Improvestructural strengthVSAvoidstick-slip phenomenon
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

A plastic slide plate is introduced as an intermediary component between the metal support beam and the whey draining belt. The slide plate reduces friction by providing a low-friction plastic surface that the belt slides over, eliminating the stick-slip phenomenon while maintaining the structural strength of the metal beam.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The support structure uses a composite material approach by combining metal (for structural strength) and plastic (for low friction). The plastic slide plate is attached to the metal beam, creating a composite structure that leverages the advantages of both materials: strength from metal and low friction from plastic.

Inventive Principle:
Principle #40Composite materials

2Strength

If a metal support structure is used for the whey draining belt, then the structural strength is improved, but friction causes belt wear and limited belt life

Engineering Contradiction:
Improvestructural strengthVSAvoidbelt life
Core Design Contradiction:
StrengthVSDuration of action of moving object

Solution Approach 1:

The plastic slide plate serves as a protective intermediary between the metal support and the belt, preventing direct metal-to-belt contact. This reduces abrasive wear on the belt, extending its service life while the metal beam continues to provide necessary structural support.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If high tension is applied to the whey draining belt, then the belt stability is improved, but the machine capacity is reduced

Engineering Contradiction:
Improvebelt stabilityVSAvoidmachine capacity
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The plastic slide plate acts as a low-friction intermediary that reduces the tension required to move the belt. This allows the belt to operate with lower tension while maintaining stability, thereby increasing the machine's capacity to handle larger volumes of curd and whey mixture.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Strength

If a conventional metal support structure is used, then the structural strength is improved, but cleaning the underside of the belt becomes difficult

Engineering Contradiction:
Improvestructural strengthVSAvoidcleaning accessibility
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The plastic slide plate is designed with features such as notches and single-point contact areas that facilitate cleaning. The smooth plastic surface and geometric features allow cleaning solutions to access and clean the underside of the belt more effectively compared to a conventional metal support structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Reduces stick-slip phenomenon, extends belt life, and increases machine capacity by minimizing friction and tension while enabling effective cleaning of the belt support structure.

Implementation Method 1

friction between the belt and the belt support structure may cause interrupted motion of the belt... friction is replaced by sliding friction between the plastic belt and the plastic slide plate

Methodology Applied
Scientific EffectFriction: Friction
