Trash Container Sealing-and-Cutting Unit on Door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trash cans with built-in refill bags require users to manually tie and cut filled bags, which is unsanitary and inconvenient, and the process reduces the usable length of the bag, thereby decreasing its capacity.
Innovation Solution
A trash container equipped with a sealing-and-cutting unit that automatically seals the top of a trash bag with tape and cuts it when the door is opened, allowing for hygienic and convenient disposal of the bag without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cutting blade is installed inside the trash can to cut refill bags, then the bag cutting function is provided, but it becomes inconvenient to take filled bags out and cut them, and unsanitary for users to manually tie and discard bags
Solution Approach 1:
The sealing and cutting unit is extracted from the interior of the trash can and mounted on the exterior of the door. This allows the cutting blade and sealing mechanism to be accessible from outside the can, eliminating the need for users to manually handle and tie bags inside the cramped interior, thereby improving convenience and sanitary conditions.
Solution Approach 2:
The sealing and cutting unit automatically performs the sealing and cutting operations when the door is opened. The system self-services by using the door opening action to trigger the cutting blade and sealing tape mechanism, eliminating the need for manual user intervention in the cutting and sealing process.
2Device complexity
If the sealing member is provided inside the main body, then the cutting function is integrated, but it is very inconvenient to lay and cut the trash bag filled with garbage inside the cramped main body
Solution Approach 1:
The sealing and cutting unit is extracted from the interior of the trash can and mounted on the exterior of the door. This allows the cutting blade and sealing mechanism to be accessible from outside the can, eliminating the need for users to manually handle and tie bags inside the cramped interior, thereby improving convenience and sanitary conditions.
Solution Approach 2:
The sealing and cutting unit is positioned on the door, utilizing the door's movement and external space to provide a larger operational area. This dimensional shift from inside the cramped main body to the exterior door area allows for easier manipulation and cutting of filled bags.
3Device complexity
If the sealing member is installed in the center of the lower cover, then the cutting function is centralized, but it is very difficult to push the trash bag filled with garbage by turning it inside the main body
Solution Approach 1:
The sealing and cutting unit is extracted from the interior of the trash can and mounted on the exterior of the door. This allows the cutting blade and sealing mechanism to be accessible from outside the can, eliminating the need for users to manually handle and tie bags inside the cramped interior, thereby improving convenience and sanitary conditions.
Solution Approach 2:
The sealing and cutting unit is positioned on the door, utilizing the door's movement and external space to provide a larger operational area. This dimensional shift from inside the cramped main body to the exterior door area allows for easier manipulation and cutting of filled bags.
4Ease of operation
If the user has to take the trash bag out of the main body, raise the sealing member, and pass the bag through the sealing member, then the sealing function is provided, but the operation becomes cumbersome
Solution Approach 1:
The sealing and cutting unit automatically performs the sealing and cutting operations when the door is opened. The system self-services by using the door opening action to trigger the cutting blade and sealing tape mechanism, eliminating the need for manual user intervention in the cutting and sealing process.
Solution Approach 2:
The sealing tape and cutting blade are pre-positioned on the door in a ready state. When the door is opened, the sealing and cutting operations are immediately available without requiring the user to manually retrieve or position these components, thereby reducing the time and effort needed for the sealing operation.
