Vacuum Dust Bag Docking Ring for Single-Material Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dust bags for vacuum cleaners generate significant waste and are difficult to recycle due to their complex composition and design, leading to inefficient handling and increased environmental impact during replacement.
Innovation Solution
A dust bag design featuring a docking element with an undercut surrounding the inlet opening for secure attachment to the vacuum cleaner, made from a single material such as polypropylene-based nonwoven or natural fibers, which simplifies attachment, reduces waste, and facilitates easier recycling by eliminating the need for multiple components and complex fastening systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components (holding plate, flap, seal, handle) are used in the dust bag, then secure attachment and dust containment are improved, but device complexity and waste generation increase
Solution Approach 1:
The patent combines multiple separate components (holding plate, flap, seal, handle) into a single integrated dust bag structure. The dust bag is designed with a unified body that incorporates all necessary functions: the open end serves as the attachment interface, the body contains the collected dust, and the structure itself provides the necessary sealing and handling capabilities, eliminating the need for separate components.
Solution Approach 2:
The dust bag is designed as a multi-functional single component that simultaneously performs attachment, containment, sealing, and handling functions. The open end of the dust bag serves multiple purposes: it allows for easy attachment to the vacuum cleaner and also serves as the access point for dust collection and bag replacement, consolidating multiple functions into one universal structure.
2Adaptability or versatility
If multiple materials are used for different components, then functional requirements are met, but recyclability deteriorates
Solution Approach 1:
The dust bag is constructed from a single homogeneous material throughout its entire structure, eliminating the need for different materials in different components. This uniform material composition allows the entire dust bag to be easily recycled as a single material stream, significantly improving recyclability while still meeting all functional requirements through clever structural design.
3Reliability
If a flap and seal are added to the inlet opening, then dust containment is improved, but ease of operation deteriorates
Solution Approach 1:
The patent extracts the complex flap and seal mechanisms from the dust bag design and replaces them with a simpler approach. The dust bag uses its basic structural form - an open-ended flexible container - to achieve dust containment through the natural flexibility and fit of the bag itself, eliminating the need for additional moving parts or complex sealing mechanisms that would complicate handling.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces waste generation, simplifies the dust bag attachment process, and enhances recyclability by using a single material for the dust bag and holding device, ensuring secure positioning and easy handling during replacement.
Implementation Method 1
a filter bag made of an air-permeable material and open to the inlet opening, wherein the material of the filter bag is designed to filter the dust out of the air stream as it passes through
Implementation Method 2
the holding device is designed as a docking element surrounding the inlet opening, wherein the docking element forms an undercut for fastening the dust bag in a vacuum cleaner
