Solution Overview

Problem

Current material handling automation systems experience inefficiencies due to idle time and prolonged processing times, particularly in determining task priorities and executing tasks seamlessly within existing control systems.

Innovation Solution

The method involves an automatic mechanical material handling equipment controlled by a control system that performs first and second access tasks in parallel, with dynamic task prioritization and intermediate task management to optimize workflow, reducing idle time and processing time through integrated logic for task execution and priority reorganization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If sequential task execution is used in material handling automation systems, then task execution accuracy is improved, but idle time and processing time increase

Engineering Contradiction:
Improvetask execution accuracyVSAvoididle time and processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The control system performs preliminary evaluation of data to determine intermediate tasks before the mechanical equipment executes the first access task. This advance planning allows the system to prepare task priorities and sequences in advance, reducing idle time while maintaining execution accuracy through pre-calculated task arrangements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system eliminates idle time by continuously evaluating data, determining intermediate tasks, and executing access tasks in a seamless workflow. The control system maintains continuous operation by immediately transitioning between task evaluation, determination, and execution phases without unnecessary pauses or waiting periods.

Inventive Principle:
Principle #20Continuity of useful action

2Productivity

If parallel task execution is implemented, then productivity is improved, but task priority management complexity increases

Engineering Contradiction:
ImproveproductivityVSAvoidtask priority management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control system segments task management into distinct phases: evaluating data to determine intermediate tasks, assigning execution priorities, and executing access tasks. This segmentation allows parallel execution of multiple access tasks while maintaining clear priority management through structured, modular control steps that can be independently processed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts task priorities based on real-time evaluation of data and determination of intermediate tasks. The execution priority assignment is flexible and adaptive, allowing the control system to optimize task sequences dynamically while managing parallel execution, rather than relying on fixed static priority rules.

Inventive Principle:
Principle #15Dynamics

3Loss of time

If intermediate task determination is performed in advance, then processing time is reduced, but control system complexity increases

Engineering Contradiction:
Improveprocessing timeVSAvoidcontrol system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The control system performs preliminary evaluation of data and determination of intermediate tasks before access task execution begins. This advance determination reduces processing time during actual task execution, as the system has already identified necessary intermediate steps and assigned priorities in advance, rather than calculating them in real-time during execution.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control system automatically evaluates data, determines intermediate tasks, and assigns execution priorities without requiring external intervention or complex manual coordination. The system serves itself by autonomously managing the entire task planning and execution process, which simplifies external control requirements despite the internal complexity of automated decision-making.

Inventive Principle:
Principle #25Self-service
