Solution Overview

Problem

Existing transport systems using a cogged belt with a vertical axis face issues with the stability and orientation of support elements due to flexion stresses and impacts during movement, leading to potential coupling breaks and noise, especially when transitioning between straight and curved belt portions.

Innovation Solution

A guide system with continuous upper and lower channels and sliding elements that rotate and translate to maintain the orientation of fixing elements, ensuring stability and continuous belt activation without noise, even at high speeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If sliding block elements are used to maintain stability of support elements, then stability is improved, but impacts and stresses occur during transitions between straight and curved portions causing coupling breaks and noise

Engineering Contradiction:
Improvestability of support elementsVSAvoidcoupling reliability
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent applies the dynamics principle by making the fixing elements rotatable rather than fixed. The fixing elements can rotate to adapt to the changing geometry of the belt (straight and curved portions), eliminating impacts and stresses that occur with fixed sliding block elements during transitions. This dynamic adaptation maintains both stability and reliability simultaneously.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If sliding block elements are constrained in straight guides, then stability during straight portions is improved, but sticking occurs during transitions jeopardizing continuous activation

Engineering Contradiction:
Improvestability during transportVSAvoidcontinuous activation
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The fixing elements are designed to rotate freely, adapting dynamically to the belt's geometry changes. This eliminates the sticking problem that occurs with constrained sliding block elements during transitions between straight and curved portions, ensuring continuous belt activation while maintaining stability during transport.

Inventive Principle:
Principle #15Dynamics

3Strength

If fixing elements are arranged internally on the inner side of the cogged belt, then coupling is achieved, but flexion stresses during activation compromise product orientation

Engineering Contradiction:
Improvecoupling strengthVSAvoidproduct orientation
Core Design Contradiction:
StrengthVSStability of the object's composition

Solution Approach 1:

The fixing elements are designed to rotate about their own axes, allowing them to adapt to the flexion stresses generated during belt activation. This dynamic capability maintains the coupling strength while preserving correct product orientation, as the fixing elements can adjust their angular position to accommodate belt deformation.

Inventive Principle:
Principle #15Dynamics
