Solution Overview

Problem

Existing coating profile devices face challenges in managing consumables, particularly coating material, leading to potential shortages and disruptions in production due to lack of real-time inventory tracking.

Innovation Solution

A rotational speed measuring device and evaluation system calculate the remaining length of coating material on a roll by measuring the roll's rotational speed and transport speed, allowing for timely replenishment or roll changes, with optional automatic thickness measurement and display of material status on a control panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual monitoring of coating material is used, then operational simplicity is maintained, but material shortages occur leading to production interruptions

Engineering Contradiction:
Improvecontinuous operationVSAvoidmonitoring system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system enables automatic self-monitoring of coating material consumption by utilizing existing process data (rotational speed, transport speed) to calculate remaining material length without requiring manual intervention or additional sensors

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The evaluation device continuously calculates and provides feedback on the remaining coating material length based on measured rotational speed and transport speed, enabling timely replenishment decisions to maintain continuous operation

Inventive Principle:
Principle #23Feedback

2Productivity

If real-time material tracking is implemented, then production continuity is ensured, but system complexity increases

Engineering Contradiction:
Improveproduction continuityVSAvoidmeasurement and evaluation system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The existing speed measuring device and control system perform multiple functions: they measure rotational speed for process control, measure transport speed for synchronization, and now also enable calculation of remaining material length for inventory management

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

Solution Approach 2:

The evaluation device acts as an intermediary that processes readily available speed data to derive material consumption information, avoiding the need for direct material length measurement sensors

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of time

If no material inventory monitoring is used, then device simplicity is maintained, but unexpected roll changes disrupt production

Engineering Contradiction:
Improvedowntime for roll changesVSAvoidmaterial monitoring system
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system calculates and displays remaining material length in advance, enabling proactive scheduling of roll changes during planned downtime rather than unexpected interruptions during production

Inventive Principle:
Principle #10Preliminary action
