Solution Overview

Problem

Existing conveyor belt systems fail to effectively prevent longitudinal and transverse deformations when transporting products at elevated temperatures, leading to strain and potential damage to the products.

Innovation Solution

A conveyor belt system featuring a drive roller with a constant section cylinder and conical tip teeth, where the mesh drive belt holes align with the teeth, supported by a sliding plate to reduce strain, and a connecting element for easy maintenance and cost-effective upgrades.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional rollers with cylindrical surfaces and parallelogram-shaped protrusions are used, then the belt can be driven, but longitudinal and transverse deformations occur when transporting elements at elevated temperatures

Engineering Contradiction:

Improveelevated temperature transport capabilityVSAvoidbelt deformation

Core Design Contradiction:

TemperatureVSShape

Solution Approach 1:

The roller surface features conical tip teeth instead of cylindrical protrusions. The conical geometry with curved surfaces allows the belt holes to engage and disengage more smoothly, reducing longitudinal and transverse deformations of the mesh belt when transporting elements at elevated temperatures.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Temperature

If toothed cylindrical segments with different thermal expansion coefficients are used, then thermal expansion differences are exploited, but the belt still experiences strain and deformation

Engineering Contradiction:

Improvethermal expansion utilizationVSAvoidbelt strain

Core Design Contradiction:

TemperatureVSStability of the object's composition

Solution Approach 1:

The conical tip geometry provides a gradual engagement and disengagement surface that reduces shock loading and strain on the belt, even when thermal expansion differences between roller material and belt material are present.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The roller design incorporates conical teeth with specific geometric parameters (angle, height, spacing) that optimize the interaction with belt holes under thermal conditions, reducing deformation through parameter optimization rather than material selection alone.

Inventive Principle:

Principle #35Parameter changes

3Strength

If regions without protrusions are added to maintain roller rigidity, then structural stability improves, but the complexity of the roller design increases

Engineering Contradiction:

Improveroller rigidityVSAvoidroller structure complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The roller features localized conical tip teeth at specific positions rather than continuous protrusions. This localized geometry provides the necessary engagement points while maintaining overall roller rigidity, avoiding the need for complex reinforcement structures.

Inventive Principle:

Principle #3Local quality
