Solution Overview

Problem

Intermittent filling and sealing machines have a low output due to bottlenecks at the closing station, where caps are applied, and are complex and expensive to maintain, whereas continuous machines are overly complex and costly.

Innovation Solution

The machine incorporates a capping station with a movable cap feed and sorting device, allowing caps to be placed on containers during idle times using a cap feeder with a drive mechanism, enabling efficient closure even when containers are stationary or moving, with a simple and cost-effective design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a continuous machine is used for filling and sealing containers, then high output is achieved, but the machine becomes very complex and expensive

Engineering Contradiction:
ImproveoutputVSAvoidmachine complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cap feed is made movable instead of stationary, allowing it to move together with the containers during intermittent operation. This dynamic adaptation enables the capping station to maintain high productivity like continuous machines while using the simpler intermittent machine structure.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If an intermittent machine is used for filling and sealing containers, then the structure is simpler and more cost-effective, but the output is relatively low due to idle time

Engineering Contradiction:
Improvestructure simplicityVSAvoidoutput
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The movable cap feed eliminates idle time at the capping station by continuing to cap containers during both moving and idle phases of the intermittent cycle. This ensures continuous useful action at the closing station, maximizing output while maintaining the simplicity of intermittent machine structure.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of manufacture

If the machine operates intermittently with containers moving forward about one-third of the time, then cost-effective manufacturing is achieved, but the closing station becomes a capacity bottleneck

Engineering Contradiction:
Improvemanufacturing cost-effectivenessVSAvoidclosing station throughput
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The movable cap feed serves itself by moving together with the containers, automatically maintaining proper alignment and spacing without requiring complex synchronization mechanisms. This self-service approach maintains cost-effective manufacturing while eliminating the closing station bottleneck.

Inventive Principle:
Principle #25Self-service
