Solution Overview

Problem

Current logistics train systems require manual intervention for loading and unloading materials, which is labor-intensive and inefficient, especially with heavy loads, and lacks automation for consistent performance.

Innovation Solution

An extendable trailer system with automated or semi-automated capabilities, using electrically powered telescopic mechanisms and sensors for automatic loading and unloading, integrated with Programmable Logic Controllers (PLC) for control and data management, allowing for flexible and safe material handling without human intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual intervention is used for loading and unloading materials, then operational flexibility is maintained, but labor intensity increases and efficiency decreases

Engineering Contradiction:
Improvematerial handling efficiencyVSAvoidmanual labor requirement
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system enables automated self-service material handling where the extendable trailer autonomously loads and unloads mobile platforms without human intervention. The PLC-controlled system automatically extends the trailer, positions it under platforms, and performs loading/unloading operations, eliminating manual labor while maintaining operational flexibility through programmable control sequences.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical operations are replaced with an automated electromechanical system. The PLC controls electric motors that drive the extendable trailer's movement and positioning mechanisms, substituting human-operated mechanical systems with automated control systems that include sensors, actuators, and programmable logic for precise material handling operations.

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

2Reliability

If automation is implemented for material handling, then human error is reduced and consistency is improved, but system complexity increases

Engineering Contradiction:
Improveoperational consistencyVSAvoidautomation system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The automated system incorporates sensors that provide real-time feedback to the PLC controller about the trailer's position, platform location, and operational status. This feedback mechanism enables the system to automatically adjust its operations, maintain precise positioning, and ensure consistent performance while reducing human error through closed-loop control rather than open-loop automation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The PLC-based control system serves multiple functions: it controls the extendable trailer's movement, manages loading and unloading sequences, monitors sensor data, and handles error conditions. This multi-functional approach consolidates complexity into a single programmable controller rather than requiring separate control systems for each function, making the automation more manageable and reliable.

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

3Adaptability or versatility

If extendable trailer is used to reach distant platforms, then coverage area is increased, but structural stability may be compromised

Engineering Contradiction:
Improvereach distanceVSAvoidtrailer stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The trailer employs a dynamic extension mechanism that allows it to adjust its length based on the distance to the mobile platform. The extendable sections can be deployed incrementally to reach distant platforms while maintaining structural integrity through controlled extension. The system dynamically adapts its configuration to match the required reach distance rather than being fixed at maximum extension.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The extendable trailer uses a telescopic structure where smaller sections are nested within larger ones, similar to nested dolls. This nesting arrangement allows the trailer to compactly store its extended sections when not in use and progressively deploy them when reach distance requires, maintaining stability by keeping the structure compact during transport and only extending when needed for loading operations.

Inventive Principle:
Principle #7Nested doll (Nesting)
