Solution Overview

Problem

Current process management techniques in production systems lack effective grouping and prioritization of tasks, leading to inefficient production workflows and potential delays in meeting deadlines.

Innovation Solution

A production system that includes a server, administrator terminal, and barcode reader, which groups tasks by priority and deadline, allowing for real-time monitoring and management of processes across multiple devices, ensuring timely completion of high-priority tasks and optimizing resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If tasks are managed without grouping and prioritization, then the production system is simple to operate, but production efficiency deteriorates and delays occur

Engineering Contradiction:
Improveproduction efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments tasks into groups based on priority levels (high, medium, low) and deadlines, allowing differentiated management of task batches. This segmentation enables the system to handle complexity by organizing tasks into manageable units with distinct characteristics, improving productivity without overwhelming operational complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts processing priorities and displays based on real-time task status, deadlines, and group characteristics. The display portion adapts its presentation based on task priority levels, and the control portion dynamically schedules processing operations, enabling the system to respond to changing conditions while maintaining structured organization

Inventive Principle:
Principle #15Dynamics

2Reliability

If all tasks are processed equally without prioritization, then the processing flow is simple, but deadline compliance deteriorates

Engineering Contradiction:
Improvedeadline complianceVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system applies different processing strategies to different task groups based on their priority levels and deadline characteristics. High-priority tasks with imminent deadlines receive expedited processing and prominent display, while low-priority tasks follow standard processing flows. This local differentiation ensures deadline compliance for critical tasks without requiring complete operational complexity throughout the system

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The display portion provides real-time feedback to operators showing task status, priority levels, and deadline information. This feedback mechanism enables operators to understand which tasks require immediate attention and adjust their actions accordingly, improving deadline compliance while maintaining operational simplicity through intuitive information presentation

Inventive Principle:
Principle #23Feedback

3Loss of time

If tasks are not grouped by priority and deadline, then the display and management process is simple, but time consumption increases

Engineering Contradiction:
Improvetime consumptionVSAvoidmanagement complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system segments tasks into priority-based groups that can be displayed and managed separately. The display portion presents tasks in organized groups with distinct visual characteristics based on priority level, enabling operators to quickly identify and address time-critical tasks without wading through all tasks uniformly. This segmentation reduces time consumption by focusing attention on what matters most

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary organization of tasks into priority groups and deadline categories before processing begins. This preliminary classification is done automatically by the control portion, which then schedules processing operations based on pre-established priority levels. This advance organization eliminates the need for operators to manually sort and prioritize tasks, reducing time consumption while keeping management operations simple

Inventive Principle:
Principle #10Preliminary action
