Collection bag for receiving a collected material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collection bags for suction devices face difficulties in efficiently emptying both dry and wet materials due to moisture-dependent accumulation and the risk of inadvertent opening during operation.
Innovation Solution
A collection bag design featuring a foldable outlet section with a reinforced edge and a closure mechanism, secured by a buckle, allows for secure closure and easy opening, preventing accidental opening during operation and facilitating effective emptying of materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the emptying opening is designed to be easily accessible for simple opening, then the ease of operation is improved, but the risk of inadvertent opening during operation increases, worsening the reliability
Solution Approach 1:
The outlet section is pre-configured in a folded state during manufacturing, creating a latch mechanism that automatically engages with the collection bag. This preliminary arrangement ensures that the outlet section remains closed during operation but can be easily opened when needed, resolving the contradiction between ease of operation and prevention of inadvertent opening
Solution Approach 2:
The folded outlet section acts as a self-latching mechanism where the geometry of the folded edge itself provides the closure function. The outlet section serves both as the closing element and the securing mechanism, eliminating the need for additional complex fastening components while maintaining reliability and ease of operation
2Reliability
If the outlet section is positioned inside the collection bag in closed position, then the reliability of closure is improved, but the device complexity increases due to the foldable mechanism
Solution Approach 1:
The outlet section is constructed as a flexible, foldable component that can be easily manipulated between open and closed positions. This flexibility allows the outlet section to be positioned inside the collection bag for secure closure while maintaining simplicity of the overall mechanism, avoiding the need for rigid, complex closing structures
Solution Approach 2:
Instead of using a traditional outward-opening mechanism, the outlet section is designed to fold inward into the collection bag. This inverted approach provides more secure closure by positioning the closing element inside the bag, while the foldable nature keeps the mechanism simple and manageable
3Reliability
If the opening edge is folded into the collection bag to secure closure, then the reliability is improved, but the ease of operation worsens due to the folded structure
Solution Approach 1:
The outlet section is pre-folded during manufacturing into a configuration that naturally latches within the collection bag. This preliminary folding creates a self-sustaining closed position that is secure during operation but can be easily released when emptying is needed, balancing reliability with operational ease

AI summary
A collection bag is for receiving a collected material and an emptying opening configured in a specific shape for the collection bag which has a receiving space defined by a woven cloth. The receiving space is defined by outer edges of the collection bag. The woven cloth is at least partially air-permeable. The receiving space has an inlet opening for a blower air flow supplying the material and a closable emptying opening for removing the material. The receiving space opens into a tubular outlet section, the open end thereof forming the emptying opening. In a closed position of the outlet section, the receiving space or the emptying opening is closed. In an open position, the receiving space is connected to the surroundings via the emptying opening. In its open position, the outlet section protrudes from the bag and, in its closed position, the outlet section is located inside the bag.
