Solution Overview

Problem

Existing packaging machines for lollipops and confectionery face inefficiencies in speed and reliability due to frequent stopping and starting, which strains the machinery and reduces output.

Innovation Solution

The packaging machine design includes continuously rotating drums and discs with twisters and lollipop holders, allowing for simultaneous rotation and improved tool exchange, along with a take-over wheel with rotatable clamping arms for efficient lollipop handling and packaging material management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the drum is stopped and started for each lollipop packaging operation, then the packaging precision and control are improved, but the productivity and machine reliability deteriorate due to frequent stopping and starting

Engineering Contradiction:
Improvepackaging precisionVSAvoidpackaging speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The drum is designed to rotate continuously without stopping between packaging operations. Multiple lollipop holders are arranged around the drum perimeter, allowing packaging operations to be performed at different angular positions during continuous rotation, thereby eliminating idle stopping and starting time while maintaining packaging precision through controlled operational sequences.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The packaging operation is divided into multiple independent stations arranged around the drum perimeter. Each station can perform packaging operations independently while the drum continues rotating, allowing parallel processing of multiple lollipops. This segmentation enables continuous production flow without requiring the entire system to stop and start for each individual packaging operation.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If the drum is stopped and started for each lollipop packaging operation, then the control and precision are improved, but the machine reliability deteriorates due to mechanical strain from repeated stopping and starting

Engineering Contradiction:
Improvepackaging precisionVSAvoidmachine reliability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The drum maintains continuous rotation throughout the packaging process, eliminating the mechanical stress of repeated acceleration and deceleration cycles. This continuous motion significantly improves machine reliability by reducing wear on motors, bearings, and mechanical components while maintaining precise packaging control through synchronized operation of multiple holders and tools around the rotating drum.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If multiple twisters are arranged on separate discs, then the twisting capability is improved, but the device complexity increases

Engineering Contradiction:
Improvetwisting capabilityVSAvoiddisc arrangement complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Multiple twisters are mounted on the same disc structure, sharing common rotational motion and support mechanisms. This merging approach allows multiple twisting operations to be performed simultaneously on different lollipops while using a single disc assembly, thereby increasing productivity without proportionally increasing the number of separate disc components and their associated complexity.

Inventive Principle:
Principle #5Merging (Combining)
