Solution Overview

Problem

Existing article sorting apparatuses, such as loop and linear sorting machines, require multiple conveying trolleys and complex mechanisms, leading to inefficiencies in article sorting and storage.

Innovation Solution

An automatic put wall system with linearly distributed sorting-conveying assemblies, each comprising a carrying portion and a rotating portion, allows for vertical adjustment of conveying direction, and includes auxiliary rollers and a multilayer structure for efficient article sorting and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If loop sorting machine or linear sorting machine is used, then article sorting function is achieved, but device complexity increases due to multiple conveying trolleys and complex mechanisms

Engineering Contradiction:
Improvearticle sorting functionVSAvoidcomplex mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sorting system is divided into multiple independent sorting-conveying assemblies distributed linearly along the conveying direction. Each assembly includes a carrying portion and a rotating portion that can independently rotate to adjust conveying direction. This segmentation allows the system to achieve complex sorting functions through simple, modular units rather than requiring a single complex mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carrying portion is designed to rotate in the vertical direction, adding a vertical dimension to the conveying path. This allows articles to be redirected from horizontal conveying to vertical storage positions (or vice versa), achieving three-dimensional sorting capability with simple rotational motion rather than complex multi-axis mechanisms.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple conveying trolleys are used, then article conveying capability is improved, but productivity decreases due to inefficiencies in sorting and storage

Engineering Contradiction:
Improvearticle conveying capabilityVSAvoidsorting efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The conveying belt continuously moves articles through the sorting system, and the rotating portions can continuously adjust conveying directions without stopping the flow. This continuous operation eliminates idle time and waiting periods, maintaining constant productive action throughout the sorting process.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The rotating portion can dynamically adjust the conveying direction of each carrying portion in real-time based on sorting requirements. This dynamic adaptability allows the system to optimize article flow paths, reducing unnecessary movements and improving overall sorting efficiency compared to fixed-path systems.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If linear sorting machine is used, then article transport is achieved, but loss of time occurs due to to-and-fro conveyance

Engineering Contradiction:
Improvearticle transport functionVSAvoidconveyance time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

By introducing vertical rotation capability to the carrying portion, the system can redirect articles vertically to storage positions without requiring them to travel back horizontally. This eliminates the to-and-fro motion inherent in linear sorting machines, reducing conveyance time significantly.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The rotating portion can pre-position carrying portions at optimal angles before articles need to be deposited, and the system can pre-route articles through the most efficient path. This preliminary preparation of conveying paths and positions reduces waiting time and accelerates the overall sorting process.

Inventive Principle:
Principle #10Preliminary action
