Solution Overview

Problem

Packaging machines often experience significant production stops and financial losses due to faults or malfunctions in operating stations, which are not efficiently managed by current technologies, especially in high-speed production environments where spare parts and personnel may be unavailable.

Innovation Solution

A packaging machine with a central control unit that identifies and deactivates malfunctioning operating stations, allowing the machine to continue operating by bypassing the faulty station and adjusting production speed, thereby minimizing production losses and enabling maintenance to be scheduled conveniently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the machine operates at high speed with multiple operating stations, then productivity increases, but the risk of fault and malfunction increases

Engineering Contradiction:
ImproveproductivityVSAvoidrisk of fault
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The machine is divided into multiple independent functional groups, each with its own operating stations. This segmentation allows individual stations to be isolated and deactivated without affecting the entire system, enabling continued operation despite localized faults.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control unit dynamically changes operational parameters by deactivating specific operating stations when faults are detected. This parameter change allows the machine to adapt its configuration in real-time, maintaining reliability while preserving overall productivity.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a malfunctioning operating station is detected, then the machine stops to allow repairs, but production time is lost

Engineering Contradiction:
Improvefault detectionVSAvoidproduction time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The malfunctioning operating station is extracted or deactivated from the active system while the rest of the machine continues to operate. This separation allows repairs to be performed on the faulty station without stopping the entire production line, minimizing time loss.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The control unit is programmed with preliminary fault detection and response protocols. When a malfunction is detected, the system automatically deactivates the affected station and adjusts operational parameters in advance, preventing complete system shutdown and reducing production time loss.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If all operating stations are deactivated for safety, then reliability improves, but productivity drops to zero

Engineering Contradiction:
ImprovesafetyVSAvoidproductivity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Instead of uniformly deactivating all operating stations, the system applies local quality control by selectively deactivating only the specific malfunctioning station while maintaining operation of other healthy stations. This localized response preserves both safety and productivity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system takes partial action by deactivating only the necessary portion of the system (the faulty station) rather than the entire system. This partial deactivation is sufficient to maintain safety while avoiding the excessive action of complete shutdown, thereby preserving productivity.

Inventive Principle:
Principle #16Partial or excessive action
