Floor Cleaner Bag Release Handle for Hygienic Filter Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaners with filter bags often require users to directly handle and dispose of full filter bags, which can be inconvenient and pose hygiene risks, as they lack efficient mechanisms for retaining and removing the filter bags without direct contact.
Innovation Solution
A floor cleaner design featuring a pivotably mounted handle assembly with a door and filter bag retainer system, where the filter bag retainer is biased towards an engaged position by a living spring, allowing for easy installation and removal of filter bags without direct user contact, enabling safe and convenient disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users directly handle and dispose of full filter bags, then the disposal process is simple, but hygiene risks increase and user convenience decreases
Solution Approach 1:
The patent introduces a door assembly with a filter bag retainer as an intermediary mechanism between the user and the filter bag. The retainer securely holds the filter bag during operation and allows removal as part of the door assembly, enabling users to dispose of the entire assembly without direct hand contact with the bag itself, thus reducing hygiene risks while maintaining operational simplicity
Solution Approach 2:
The door assembly is segmented into the door structure, the filter bag retainer, and the filter bag itself. This segmentation allows the retainer to provide a secure mounting interface while enabling the door and retainer to be removed together as an assembly, facilitating hygienic disposal without requiring users to handle the bag directly
2Ease of operation
If a filter bag retainer system is added to enable indirect handling, then hygiene and convenience improve, but device complexity increases
Solution Approach 1:
The door assembly serves multiple functions: it provides structural closure for the handle assembly, incorporates the filter bag retainer for secure bag mounting, and acts as a removable unit for hygienic disposal. By combining these functions into a single integrated assembly, the design avoids adding separate complex mechanisms while achieving improved ease of operation and hygiene
Solution Approach 2:
The patent merges the door structure with the filter bag retainer into a single integrated door assembly. This combination allows the retainer to be selectively coupled to the door, providing secure filter bag retention while maintaining the simplicity of the overall structure. The merged design enables the entire assembly to be removed together, simplifying the disposal process without requiring additional complex components
Applied Scientific Principles
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 allows users to dispose of full filter bags without touching them, enhancing hygiene and convenience by enabling the filter bag to be removed and replaced without manual handling, thus improving user safety and ease of operation.
Implementation Method 1
a living spring formed on the handle. The filter bag retainer is configured to be movable between an engaged position and a disengaged position, and the living spring is configured to bias the filter bag retainer toward the engaged position

AI summary
A floor cleaner including a nozzle and a handle assembly pivotably mounted to the nozzle. The handle assembly including a handle, a motor housing supporting a suction source in fluid communication with the nozzle, and a bag housing defining a filter cavity. A door is removably coupled to the handle assembly and includes a retainer configured to secure a filter bag including a bag aperture to the door such that the door and the retainer are removable from the handle assembly as an assembly. The retainer includes a retainer handle positioned above the bag aperture.
