Solution Overview

Problem

Existing bagmaking and packaging apparatuses struggle with the scattering and deposition of tiny matter such as seasoning particles on devices under the former, leading to cleanliness issues and potential mechanical failures.

Innovation Solution

The apparatus incorporates a first partition member that partitions the space around the former mechanism into separate areas, a second partition member for the film supply mechanism, and a cover with a door, enhancing cleanability by preventing tiny matter from reaching critical units and facilitating easy cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a conventional bagmaking apparatus is used without partition members, then the structure is simple, but tiny matter scatters and deposits on devices under the former, reducing cleanability

Engineering Contradiction:
ImprovecleanabilityVSAvoidstructure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent introduces partition members that divide the space around the former mechanism into separate regions. The first partition member partitions the space into a first space (product feed chute side) and a second space (transverse sealing mechanism side), while the second partition member further divides the second space. This segmentation prevents tiny matter from scattering across the entire apparatus and concentrating it in specific areas that are easier to clean.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The partition members act as intermediary structures between the former mechanism and the devices under it. These partitions create physical barriers that intercept and contain tiny matter before it can reach and deposit on the sealing mechanisms and other components, thereby protecting these devices from contamination.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If partition members are added to prevent tiny matter deposition, then cleanability improves, but device complexity increases

Engineering Contradiction:
ImprovecleanabilityVSAvoidstructure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The partition members segment the internal space of the apparatus into distinct zones. The first partition member creates a first space and a second space, while the second partition member further segments the second space. This segmentation strategy contains tiny matter within specific regions, making cleaning more effective by limiting contamination to designated areas rather than spreading it throughout the entire apparatus.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If the upper surface of the partition member is uneven, then manufacturing is easier, but cleanability deteriorates due to accumulation of tiny matter

Engineering Contradiction:
ImprovecleanabilityVSAvoidsurface finish
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent specifies that the upper surface of the partition member should be substantially flat in the region where tiny matter tends to accumulate. This local quality requirement ensures that the critical surfaces prone to contamination have a smooth finish that prevents tiny matter accumulation, while other parts of the partition member can have standard manufacturing tolerances.

Inventive Principle:
Principle #3Local quality

4Productivity

If the former mechanism is fixed without reference features, then assembly is faster, but positioning accuracy relative to the partition member decreases

Engineering Contradiction:
Improveassembly speedVSAvoidpositioning accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent integrates the former base with the partition member structure, where the former base is attached to the partition member. This merging creates a unified assembly where the partition member and former mechanism are positioned relative to each other, providing stable reference features that ensure accurate positioning while maintaining assembly efficiency.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A bagmaking and packaging apparatus (100) includes a film conveyance mechanism (20), a former mechanism (3), a transverse sealing mechanism (40), and a first partition member (10). The film conveyance mechanism conveys a film (F). The former mechanism includes a product feed chute (15) and a former (14). The product feed chute has a product (P) fed to it. The former forms in a tubular shape the film conveyed by the film conveyance mechanism. The transverse sealing mechanism is disposed under the former mechanism. The transverse sealing mechanism transversely seals the tubular film to make bags (B) containing the product fed from the product feed chute. The first partition member partitions a space around the former mechanism into a first space and a second space. The first space is on the product feed chute side. The second space is on the transverse sealing mechanism side.
