Solution Overview

Problem

Current methods for delivering bulk materials from trailers to silos often result in incorrect deliveries due to human error, leading to administrative burdens and potential safety hazards, especially in environments with multiple nearby silos.

Innovation Solution

An automated logical coupling mechanism using wireless communication between a trailer and silos, involving movable connection means with wireless communication capabilities, ensures correct delivery by identifying and establishing a logical coupling through NFC or RFID technology, and optionally LoRa for longer-range communication, with energy transfer and sensing systems to ensure secure and accurate connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual coupling of hoses is performed by human operator, then flexibility and adaptability are maintained, but delivery accuracy deteriorates due to human error

Engineering Contradiction:
Improvedelivery accuracyVSAvoidcoupling system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical coupling process with an automated system using wireless communication (NFC/RFID) and mechanical coupling means. The reader device automatically detects the silo's identification signal and establishes a logical coupling, eliminating human error in the coupling process while maintaining system adaptability through programmable logic.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service automation where the reader device on the trailer autonomously performs identification, verification, and coupling establishment without human intervention. The mechanical coupling means automatically engages with the silo's coupling interface, and the control unit autonomously manages the logical coupling based on detected signals.

Inventive Principle:
Principle #25Self-service

2Reliability

If automated identification system is implemented, then delivery accuracy is improved, but device complexity increases due to additional communication components

Engineering Contradiction:
Improvedelivery accuracyVSAvoidcommunication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The reader device serves multiple functions: it acts as a wireless communication interface for NFC/RFID identification, a logical coupling establishment device, and a communication bridge between the trailer and silo systems. This multi-functionality reduces the need for separate dedicated components for each function.

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

Solution Approach 2:

The patent introduces a logical coupling as an intermediary layer between the physical mechanical coupling and the control systems. This logical coupling, established through wireless communication, mediates the connection verification and data exchange, simplifying the overall system architecture by separating identification from physical connection management.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If logical coupling verification is performed, then delivery safety is improved, but operation time increases due to additional verification steps

Engineering Contradiction:
Improvedelivery safetyVSAvoidcoupling verification time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs identification and logical coupling establishment as preliminary actions before the actual material transfer begins. The reader device detects the silo's identification signal and establishes the logical coupling in advance, so that when material transfer starts, the verification is already complete, minimizing additional time during the critical transfer phase.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The wireless communication and logical coupling verification occur continuously during the approach and coupling phases, rather than as discrete interruptive steps. The system maintains continuous detection and verification, allowing the useful action of material transfer to proceed without interruption once the logical coupling is established.

Inventive Principle:
Principle #20Continuity of useful action
