Solution Overview

Problem

Conventional filter assemblies for vacuum cleaners require time to dry adhesives and are difficult to assemble, increasing production costs and compromising work performance due to the use of adhesives and additional sealing materials.

Innovation Solution

A filter assembly for vacuum cleaners that uses a gasket member to seal between the discharge grill, filter member, and main body, eliminating the need for adhesives by utilizing a soft or synthetic rubber gasket with a sealing reinforcement unit and combination protrusions for easy assembly and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesives are used to bond the discharge grill and filter member, then sealing between components is achieved, but assembly time increases due to drying time and application difficulty

Engineering Contradiction:

Improvesealing qualityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The invention extracts and eliminates the adhesive bonding process from the assembly system. Instead of using adhesives to bond the discharge grill and filter member, the patent uses a gasket member that provides sealing through mechanical insertion and deformation, completely removing the time-consuming adhesive application and drying steps while maintaining effective sealing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the chemical bonding mechanism (adhesives) with a mechanical sealing system. The gasket member, made of elastic material, is inserted into a groove and deforms under compression to create a seal between the discharge grill and filter member, substituting chemical bonding with mechanical deformation and elastic recovery.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If adhesives and separate sealing materials are used together, then sealing is achieved, but production cost increases

Engineering Contradiction:

Improvesealing qualityVSAvoidproduction cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The invention merges the sealing functions into a single integrated gasket member. The gasket member simultaneously seals between the discharge grill and filter member, and between the discharge grill and main body, eliminating the need for multiple separate sealing materials and adhesives, thereby reducing material costs and simplifying the manufacturing process.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The gasket member performs multiple sealing functions in one component. It provides sealing at two different locations: between the discharge grill and filter member, and between the discharge grill and main body, making it a universal sealing solution that replaces multiple specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If conventional filter assembly with adhesives is used, then components are bonded, but work performance is compromised due to assembly complexity

Engineering Contradiction:

Improvecomponent bondingVSAvoidwork performance

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The invention segments the sealing function from the bonding function. Instead of relying on adhesives to both bond and seal, the gasket member is inserted into a dedicated groove that separates the structural bonding (provides by the groove structure) from the sealing function (provided by the elastic gasket material), allowing each to optimize its performance independently.

Inventive Principle:

Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
