Solution Overview

Problem

Existing conveyor assemblies in retail settings are often fixed and inflexible, making it difficult to accommodate varying sizes and dimensions of merchandise receiving areas, and they lack the ability to easily interchange, replace, and reconfigure sortation modules.

Innovation Solution

A modular conveyor assembly composed of interchangeable and assignable sortation modules, each with multi-directional sorting capabilities and controlled by a controller that receives an IP address, allowing for dynamic configuration and reconfiguration to adapt to different space requirements and sortation needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed conveyor assembly is used, then the structure is stable and simple, but it cannot accommodate varying sizes and dimensions of merchandise receiving areas

Engineering Contradiction:

Improveadaptability to varying space requirementsVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The conveyor assembly is divided into multiple independent sortation modules that can be individually assembled, disassembled, and reconfigured. Each module contains its own rollers, controllers, and sorting mechanisms, allowing the system to be customized for different space requirements by selecting and arranging appropriate numbers and types of modules.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from a fixed configuration to a dynamic, reconfigurable structure. Sortation modules can be added, removed, or repositioned along the conveyor chain, and the control system dynamically assigns IP addresses and routing instructions to accommodate changing operational requirements and space constraints.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If sortation modules are made interchangeable and reconfigurable, then adaptability improves, but difficulty of detecting and measuring module positions increases

Engineering Contradiction:

Improveinterchangeability of sortation modulesVSAvoiddifficulty of tracking module positions

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

Each sortation module is equipped with a controller that provides feedback to the central control circuit. The controllers communicate their operational status and position information, enabling the system to track and identify each module's location within the conveyor chain despite frequent reconfigurations and interchanges.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The control circuit acts as an intermediary that manages communication between the central control system and individual sortation modules. It assigns unique IP addresses to each module and translates routing decisions into specific controller instructions, facilitating seamless identification and control of interchangeable modules.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If a modular conveyor assembly is used, then ease of assembly and reconfiguration improves, but device complexity increases

Engineering Contradiction:

Improveease of assembly and reconfigurationVSAvoidmodular system complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The sortation modules are designed with universal interfaces and standardized configurations that allow them to function in multiple positions and roles within the conveyor system. Each module can serve different sorting destinations depending on its position in the chain, reducing the total number of unique components needed and simplifying assembly procedures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system incorporates automatic identification and configuration capabilities where sortation modules self-register with the control system upon assembly. The controllers automatically receive IP addresses and operational parameters from the control circuit, reducing manual configuration requirements and simplifying the assembly process.

Inventive Principle:

Principle #25Self-service

AI summary

There is provided a conveyor assembly for sorting merchandise items. In one form, the conveyor assembly includes: a merchandise identification module; sortation modules each comprising a multi-directional sorting portion with two sets of rollers, a first wing including a third set of rollers, a second wing including a fourth set of rollers, and a controller configured to receive an IP address; a first, disassembled state of the sortation modules; a second, assembled state of the sortation modules; a merchandise database; and a control circuit configured to receive identifying information about an unsorted merchandise item, assign a unique IP address to each sortation module corresponding to the position of the sortation module, determine a sortation destination for the unsorted merchandise item, determine the sortation module corresponding to the sortation destination; and instruct the controller of the corresponding sortation module to divert the unsorted merchandise item to the sortation destination.
