Solution Overview

Problem

Conventional conveyor systems in automated storage and retrieval systems move containers slowly due to their inability to securely hold them in place during acceleration, leading to inefficiencies in warehouse operations.

Innovation Solution

A conveyor system with carts equipped with gripping mechanisms that securely engage storage containers, allowing them to be accelerated without sliding, using mechanisms like L-beam side members and pivotable engagement members to maintain stability during movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional conveyor systems use simple support structures without gripping mechanisms, then the device complexity is reduced, but the containers slide during acceleration causing slower movement and reduced productivity

Engineering Contradiction:
Improvecontainer movement speedVSAvoidconveyor system structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The conveyor system is divided into independent modular carts, each with its own gripping mechanism. This segmentation allows each cart to independently secure and accelerate containers without affecting other carts, enabling faster movement while keeping individual cart complexity manageable

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The gripping mechanisms are designed to dynamically engage and disengage from containers based on acceleration requirements. During acceleration phases, the gripping members securely hold containers to prevent sliding; during deceleration or idle phases, they release to allow easy container transfer, thus enabling high-speed operation without permanent complex structures

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If gripping mechanisms are added to securely hold containers during acceleration, then container stability is improved, but the device complexity increases

Engineering Contradiction:
Improvecontainer position stabilityVSAvoidcart structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The gripping mechanism uses intermediary gripping members that can be raised or lowered to engage with container features. These intermediaries provide the necessary stabilization during acceleration without requiring complex rigid attachment structures, as the gripping members can adapt to different container types and sizes

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The gripping mechanisms are designed to automatically engage with container features through simple actuation, and can be released by basic counter-forces or actuation. This self-service capability provides stable container holding without requiring complex control systems or multiple mechanical components

Inventive Principle:
Principle #25Self-service

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

The system enables faster movement of containers between positions, enhancing the efficiency of the conveyor system and overall warehouse operations by preventing containers from dismounting during acceleration.

Implementation Method 1

The cart comprises a gripping mechanism which is configured to releasably engage a storage container on the cart, and so hold the storage container in a fixed position relative to the cart as the cart moves along the rail
