Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing machines require complex configurations with mechanisms for cutting and heat-sealing film, leading to significant material loss and potential contamination, as well as safety hazards during maintenance.
Innovation Solution
A sealing machine design that includes a holding part for containers and a joining part for lids, allowing for pre-formed sheet lids to be joined to containers without cutting, reducing material loss and contamination risk, and simplifying the device configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long body of film is cut into predetermined shapes and heat-sealed to containers, then the sealing function is achieved, but material loss increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-forming lids from sheet material before the sealing process. Instead of cutting film during operation, lids are prepared in advance as discrete pieces that are then directly applied to containers, eliminating waste from cutting operations
Solution Approach 2:
The invention extracts the cutting operation from the sealing process entirely. By using pre-formed sheet lids instead of continuous film that requires cutting, the harmful cutting step is removed, thereby eliminating material loss and dust generation
2Shape
If film is cut from a long body into predetermined shapes, then the lid is formed, but dust is generated and may contaminate the container
Solution Approach 1:
The cutting operation that generates dust is completely extracted from the sealing process. Pre-formed sheet lids are used instead of cutting film on-demand, thereby eliminating the source of dust contamination while still achieving the required lid shape
Solution Approach 2:
Lids are pre-formed into their final shapes before use, eliminating the cutting step that occurs at the moment of sealing. This preliminary formation of lids prevents dust generation during the sealing operation
3Reliability
If a mechanism for cutting film is added to the sealing machine, then the sealing process is complete, but the device configuration becomes complicated
Solution Approach 1:
The cutting mechanism is extracted from the sealing machine entirely. By using pre-formed sheet lids, the complex cutting mechanism is removed, simplifying the device configuration while maintaining complete sealing functionality
Solution Approach 2:
The lid formation step is moved to before the sealing process, performed separately as a preliminary action. This eliminates the need for integrated cutting mechanisms in the sealing machine, reducing device complexity
4Ease of manufacture
If a cutting mechanism is included in the sealing machine, then film can be processed on-site, but safety hazards arise during maintenance
Solution Approach 1:
The cutting mechanism is extracted from the sealing machine, eliminating the safety hazard entirely. Pre-formed sheet lids are used instead, so no cutting operation occurs within the sealing device, ensuring maintenance safety
Solution Approach 2:
Film processing (cutting) is performed as a preliminary action outside the sealing machine, before the lids are applied. This separates the hazardous cutting operation from the sealing device, eliminating maintenance safety risks

AI summary
A sealing machine for sealing, with a lid, an opening part of a container having the opening part and an edge part forming an outer circumferential edge of the opening part, includes: a holding part including a holding body that holds the container in a state where the edge part of the container is exposed; and a joining force applying part including a joining body for joining the lid to an edge part formed on a periphery of the opening part. The holding part is formed so that a lid formed in advance into a sheet can be disposed so as to face the opening part of the holding body. The joining part joins the lid formed in advance into a sheet to the container.
