Vacuum Cleaner Filter Assembly With Gasket Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter assemblies for vacuum cleaners require time-consuming adhesive bonding and additional sealing materials, leading to increased production costs and reduced assembly efficiency due to the complexity of applying adhesives between the discharge grill, filter, and main body.
Innovation Solution
A filter assembly utilizing a gasket member made of soft or synthetic rubber that seals between the discharge grill and filter, and the main body of the vacuum cleaner, with a sealing reinforcement unit that uses air pressure to maintain contact and eliminate the need for adhesives, featuring combination protrusions and grooves for easy assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesives are used to bond the discharge grill and filter, then sealing between components is achieved, but assembly time increases and work performance decreases
Solution Approach 1:
The patent removes the adhesive bonding step entirely by introducing a gasket member that provides sealing through mechanical insertion and elastic deformation. The gasket member is inserted into a groove and compressed by a pressing member, eliminating the need for time-consuming adhesive application and drying processes while maintaining effective sealing between the discharge grill and filter.
Solution Approach 2:
The gasket member serves as an intermediary element between the discharge grill and filter, providing the sealing function that previously required adhesives. This intermediate component enables direct mechanical assembly without chemical bonding, significantly reducing assembly time while ensuring reliable sealing through its elastic properties and compression mechanism.
2Reliability
If adhesives and separate sealing materials are used together, then sealing is achieved, but production cost increases
Solution Approach 1:
The patent combines the sealing function into a single integrated gasket member that eliminates the need for separate sealing materials and adhesives. The gasket member, made of elastic material, provides both the sealing interface and the bonding function through its compression and elastic recovery, reducing material costs and simplifying the manufacturing process.
Solution Approach 2:
The gasket member is designed as a simple, inexpensive elastic component that can be easily replaced if needed. This disposable-like approach with the gasket member reduces overall production costs compared to using expensive adhesives and separate sealing materials, while maintaining effective sealing through its elastic deformation and compression mechanism.
3Strength
If adhesives are used for bonding, then connection strength is achieved, but assembly complexity increases
Solution Approach 1:
The patent extracts the adhesive bonding step from the assembly process and replaces it with a mechanical insertion and compression system. The gasket member is simply inserted into a groove and compressed by a pressing member, eliminating the complex multi-step adhesive application process while maintaining strong connection through elastic deformation and friction.
Solution Approach 2:
The patent replaces the chemical bonding system (adhesives) with a mechanical system consisting of the gasket member, groove, and pressing member. This mechanical approach uses elastic deformation, compression, and friction to achieve strong bonding strength without the complexity of adhesive application, drying, and curing processes.
4Reliability
If the filter is permanently bonded with adhesives, then sealing is maintained, but maintenance and reassembly become difficult
Solution Approach 1:
The patent introduces dynamic elements to the sealing system: the gasket member can be compressed during assembly and then elastically recovers to maintain sealing pressure. The pressing member can be moved to compress or release the gasket, enabling easy disassembly and reassembly while maintaining sealing durability through the elastic properties of the gasket material.
Solution Approach 2:
The patent segments the sealing function into distinct components: the gasket member provides the sealing interface, the groove provides the mounting structure, and the pressing member provides the compression force. This segmentation allows the filter to be easily removed and reinstalled by simply releasing the pressing member, while the gasket member maintains sealing durability through its elastic deformation and recovery.
