Solution Overview

Problem

Current goods sorting systems, such as cross-belt and robot steel platform systems, face inefficiencies in sorting accuracy and labor costs due to inflexible design, high construction costs, and manual handling, leading to reduced productivity and increased errors.

Innovation Solution

A goods sorting system comprising a control server, delivery robots, and carrying robots that communicate and coordinate to optimize routes and container management, using QR codes or barcodes for route identification and infrared sensors for volume detection, allowing for automated sorting and reduced manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If cross-belt sorting system or robot steel platform sorting system is used, then goods sorting automation is achieved, but construction cost increases and system complexity increases

Engineering Contradiction:
Improvegoods sorting automationVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The sorting system is divided into independent functional modules: delivery robots for goods delivery, carrying robots for container transport, and collection containers for goods accumulation. Each module operates independently but coordinates through the control server, reducing overall system complexity while maintaining automation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The robots are designed with multi-functionality, capable of performing both delivery and carrying tasks. The system can adapt to different sorting scenarios by reconfiguring robot assignments and routes, reducing the need for specialized equipment and lowering construction costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Extent of automation

If cross-belt sorting system is used, then goods sorting is automated, but the number of delivery ports is fixed and extending flexibility is poor

Engineering Contradiction:
Improvegoods sorting automationVSAvoidextending flexibility
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts delivery routes and container assignments based on real-time conditions. The control server reconfigures robot paths and container allocations automatically, allowing the system to adapt to changing demands without physical modifications to the infrastructure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters such as delivery routes, container positions, and robot assignments dynamically. This allows the same physical infrastructure to serve multiple configurations and scaling scenarios, improving extending flexibility without increasing construction complexity.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If manual collection and buffering of goods is performed, then labor cost is reduced, but sorting efficiency decreases and sorting accuracy decreases

Engineering Contradiction:
Improvemanual handling reductionVSAvoidsorting efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system implements self-service through automated robot operations. Delivery robots autonomously navigate to containers, deposit goods, and return for new tasks without human intervention. The control server manages coordination automatically, maintaining high sorting efficiency while eliminating manual labor.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback mechanisms where sensors detect goods delivery status, container fill levels, and robot positions. This real-time feedback enables the control server to optimize routes, reassign tasks, and maintain high sorting accuracy and efficiency automatically without manual monitoring.

Inventive Principle:
Principle #23Feedback

4Extent of automation

If robot steel platform sorting system is used, then automation is improved, but robot density is high causing long waiting time and stopping

Engineering Contradiction:
Improveautomation levelVSAvoidwaiting time
Core Design Contradiction:
Extent of automationVSLoss of time

Solution Approach 1:

The system transitions from a two-dimensional platform-based approach to a three-dimensional space utilization model. Robots operate in vertical and horizontal dimensions simultaneously, with containers arranged in arrays that allow multiple delivery routes. This dimensional expansion reduces robot congestion and waiting time while maintaining high automation levels.

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

Solution Approach 2:

The control server performs preliminary route planning and container allocation before robots begin delivery tasks. By pre-configuring optimal paths and anticipating bottlenecks, the system minimizes waiting time and stopping during delivery operations, maintaining high automation efficiency.

Inventive Principle:
Principle #10Preliminary action
