Vacuum Cleaner Dust Bag Identification for Correct Bag Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in selecting the correct dust bag for their vacuum cleaners due to insufficient information on packaging and the use of identical retaining plates for bags with different capacities, leading to confusion, especially when using multiple vacuum cleaners in a household.
Innovation Solution
Dust bags with different capacities are designed to have identically shaped holding plates that include unique identifiers and license plates, ensuring easy differentiation between vacuum cleaner types and their corresponding dust bags, with these identifiers also appearing on the packaging for purchasing assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If identical retaining plates are used for dust bags with different capacities, then manufacturing cost is reduced, but user confusion increases and correct bag selection becomes difficult
Solution Approach 1:
The patent applies color coding to retaining plates and packaging to differentiate dust bag capacities. Different colors are assigned to different bag capacities (e.g., color A for 4L, color B for 5.8L), allowing users to quickly identify the correct bag size without complex markings or additional information on packaging.
2Reliability
If dust bags with different capacities are offered for different vacuum cleaners, then proper fit is ensured, but selection complexity increases for users with multiple vacuum cleaners
Solution Approach 1:
The patent uses color-coded retaining plates that match the color coding of the corresponding vacuum cleaner types. This creates a simple visual matching system where users can identify the correct bag by color correspondence between their vacuum cleaner and the bag's retaining plate, eliminating complex selection processes.
Solution Approach 2:
The patent changes the visual parameter (color) of the retaining plate to encode information about bag capacity and compatibility. This allows multiple bag types to be distinguished through a single visual parameter rather than requiring users to interpret multiple specifications or packaging information.
3Ease of manufacture
If insufficient information is provided on dust bag packaging, then packaging cost is reduced, but user ability to select correct bag is impaired
Solution Approach 1:
The patent transfers identification information from verbal/textual form on packaging to visual form through color coding. The colored retaining plate itself serves as the identification marker, eliminating the need for extensive text, symbols, or specifications on the packaging while maintaining clear user guidance.

AI summary
The system comprises two vacuum cleaners, which are equipped with dust areas. The receivers of the dust areas and the dust collection bags (73) are provided with labels (731,1011). The receiver of the former dust area and the dust collection bag fitted at the former dust area carry identical labels, which differ from the identical labels at the receiver of the latter dust area and the bag fitted at the latter dust area.
