Find Innovative SolutionsGenerate Solutions

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 separates the space around the former mechanism into two areas, a first space on the product feed chute side and a second space on the transverse sealing mechanism side, preventing tiny matter from reaching these devices, and includes a flat upper surface and a cover with an opening for easy cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a bagmaking and packaging apparatus is used to pack products with tiny matter, then productivity is maintained, but tiny matter scatters and deposits on devices under the former, reducing cleanability

Engineering Contradiction:

Improvebagmaking and packaging productivityVSAvoiddeposition of tiny matter on devices

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The space around the former mechanism is divided into a first space (product feed chute side) and a second space (transverse sealing mechanism side) using a partition member. This segmentation isolates the tiny matter deposition to the first space, preventing contamination of devices in the second space and maintaining cleanability while preserving productivity.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If the space around the former mechanism is not partitioned, then device complexity is reduced, but tiny matter reaches and contaminates multiple devices, reducing cleanability

Engineering Contradiction:

Improvestructural simplicityVSAvoidcontamination of devices

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

A partition member is introduced to divide the space into isolated zones. Although this adds structural complexity, it concentrates the harmful deposition effect on a specific area, making cleaning more manageable and preventing widespread device contamination.

Inventive Principle:

Principle #1Segmentation

3Ease of manufacture

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

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidaccumulation of tiny matter

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The upper surface of the partition member is designed with a flat configuration in the region where tiny matter accumulates. This local quality change prevents debris accumulation and maintains cleanability, while the overall partition member structure remains simple enough for easy manufacturing.

Inventive Principle:

Principle #3Local quality

AI summary

A bagmaking and packaging apparatus includes a film conveyance mechanism, a former mechanism, a transverse sealing mechanism, and a first partition member. The film conveyance mechanism conveys a film. The former mechanism includes a product feed chute and a former. The product feed chute has a product 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 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.
