Integrated Gripping Structure for Waste Sack Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste collection methods using flexible bags with separate gripping and closing mechanisms are inefficient, labor-intensive, and prone to manual errors, leading to increased operational time and costs.
Innovation Solution
A support structure with integrated gripping means that controls the open or closed position of the bag's opening, allowing for easier emptying by eliminating the need for manual rope operation and enhancing reliability through a mushroom-type gripper mechanism and cable system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate rope mechanism is used to close the bag opening, then the bag can be closed securely, but the emptying process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent combines the gripping mechanism and closing mechanism into a single integrated system. The gripping means that holds the bag opening also serves as the closing means, eliminating the need for separate rope operations. This merger allows the operator to close the bag simply by detaching the gripping mechanism from the truck crane, significantly reducing the time and effort required for bag emptying while maintaining secure closure.
2Device complexity
If manual rope operation is required to open and close the bag, then the mechanism remains simple, but the operator's physical strain increases
Solution Approach 1:
The gripping mechanism is designed to automatically close the bag opening through its own structural design. When the gripping means is attached to the truck crane, the closing element is automatically positioned to seal the bag opening without requiring manual rope manipulation. This self-service feature eliminates tedious manual operations and reduces physical strain on the operator while maintaining mechanism simplicity.
3Adaptability or versatility
If separate gripping and closing mechanisms are used, then each function can be optimized independently, but the overall system complexity increases
Solution Approach 1:
The gripping means is designed to perform multiple functions simultaneously: it grips the bag opening for lifting and also serves as the closing mechanism. The closing element is integrated into the gripping structure, allowing a single component to fulfill both gripping and closing roles. This multi-functionality reduces overall system complexity while maintaining the ability to optimize each function through careful design of the integrated mechanism.
