Solution Overview

Problem

Current process management techniques in production systems fail to effectively prioritize and manage multiple processes with varying priority levels, leading to inefficiencies and potential interruptions in production workflows.

Innovation Solution

A production method and system that receive and prioritize tasks based on their priority levels, executing high-priority processes before low-priority ones, utilizing a server, administrator terminal, and barcode reader to manage and coordinate processes across multiple devices and workers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple processes with varying priority levels are managed without a priority-based execution system, then the production system can handle diverse tasks, but the production efficiency and workflow management deteriorate due to lack of prioritization

Engineering Contradiction:
Improveproduction efficiencyVSAvoidprocess management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments processes into distinct priority levels (high priority and low priority) to enable differentiated handling. Each process is assigned a priority level, allowing the system to segment the workflow into manageable categories that can be executed in a controlled manner, thereby improving production efficiency without overwhelming the management system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by determining and setting priority levels for processes before execution. The system pre-establishes the execution order based on priority levels, so that when multiple processes need to be executed, the high-priority processes are automatically selected first without requiring real-time decision-making, thus improving efficiency while keeping management simple.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If priority-based process execution is implemented, then production efficiency and workflow management improve, but the system complexity increases due to priority level management

Engineering Contradiction:
Improveworkflow managementVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the priority level determination logic as a separate, independent function from the process execution logic. The priority level is determined and stored separately, allowing the execution system to simply follow the predetermined priority order without complex real-time evaluations. This separation simplifies the overall system operation while maintaining effective priority-based management.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system implements self-service by automatically selecting and executing processes based on their predetermined priority levels without requiring manual intervention or complex scheduling algorithms. The priority-based execution mechanism serves itself by inherently organizing the workflow, reducing the operational burden on users while improving workflow management ease.

Inventive Principle:
Principle #25Self-service

3Reliability

If high-priority processes are executed before low-priority ones, then critical tasks are completed timely, but the overall processing time may increase due to reordering

Engineering Contradiction:
Improvetask completion reliabilityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by determining the optimal execution order based on priority levels before actual processing begins. By pre-establishing the execution sequence, the system ensures that critical high-priority tasks are always addressed first without requiring time-consuming real-time reordering during execution, thus maintaining reliability while minimizing time loss.

Inventive Principle:
Principle #10Preliminary action
