Trash Container Automated Bag Dispensing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trash containers require manual effort for replacing trash bags, which is inefficient and lacks automation.
Innovation Solution
A trash container equipped with a motorized roller assembly and suction pads that automatically deploy and secure a new trash bag upon removal of a filled bag, utilizing a drive assembly with sensors and a touch screen control panel for automated operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual bag replacement is used, then device complexity is reduced, but ease of operation deteriorates due to requiring user retrieval, unfolding, and securing of liners
Solution Approach 1:
The system automatically performs bag replacement without user intervention. The motorized roller assembly feeds new bags, the suction pads deploy and secure them, and the cutter separates bags - all functions serve themselves without requiring user retrieval, unfolding, or securing actions
Solution Approach 2:
Manual mechanical operations are replaced by an automated electromechanical system. The motorized roller assembly replaces manual bag feeding, the suction pads replace manual bag positioning, and the cutter assembly replaces manual bag separation, substituting user mechanical actions with automated mechanisms
2Productivity
If automated roller assembly is added, then productivity is improved through automatic bag deployment, but device complexity increases due to additional motorized components
Solution Approach 1:
The automated system is divided into distinct functional modules: the motorized roller assembly for bag feeding, the suction pad assembly for bag deployment, and the cutter assembly for bag separation. This segmentation allows each component to perform a specific function efficiently while maintaining overall system manageability
Solution Approach 2:
The motorized roller assembly serves multiple functions: it stores multiple bags in sequence, feeds bags to the deployment position, and advances the bag supply continuously. This multi-functionality increases productivity without proportionally increasing device complexity
3Ease of operation
If suction pads are used for bag deployment, then ease of operation is improved through automated bag securing, but device complexity increases due to vacuum system requirements
Solution Approach 1:
The suction pads utilize a vacuum system to automatically secure bags to the roller assembly during deployment. The vacuum mechanism provides reliable bag holding without mechanical clamps or fasteners, improving ease of operation through contactless, automated bag securing
Solution Approach 2:
The suction pads act as an intermediary between the motorized roller assembly and the trash bag. They transfer the bag from the rolled supply to the deployment position and secure it temporarily during the cutting operation, facilitating automated bag handling without direct mechanical contact
4Productivity
If automated cutter assembly is added, then productivity is improved through automatic bag separation, but device complexity increases due to additional cutting mechanism
Solution Approach 1:
The cutter assembly is positioned to engage with the bag at the precise moment of separation. It extracts the securing function from the deployment process by cleanly cutting the bag seal, allowing automatic bag separation without requiring user intervention to tear or cut the bag open

AI summary
A trash container having an automated trash bag dispensing system which automatically deploys a replacement trash bag upon removal of a filled bag. A supply of trash bags is fed into the main trash container by a motorized roller assembly. A pair of opposing suction pads are pivotally deployed inward and suction activation attracts the opposing sides of the bag to corresponding suction pads. Retraction of the suction pads functions to expand the bag to an open configuration whereby it is suitably configured to receive trash.
