Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner designs face complexity and cost issues in the arrangement and installation of secondary motor protection filters, requiring cumbersome seals and fastening elements, making filter exchange difficult and costly.
Innovation Solution
A simplified arrangement using an elastic thermoplastic polymer frame for the motor protection filter, integrated with a spline that fits into a groove on the bag compartment lid, providing a single seal element for both mounting and sealing, and allowing easy exchange during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional seal components and fastening elements are used for mounting the motor protection filter, then the filter can be securely mounted and sealed, but the installation and maintenance becomes cumbersome and complex
Solution Approach 1:
The patent combines the seal element and fastening function into a single integrated frame structure. The elastic frame simultaneously provides sealing contact with the housing and mechanical retention through the spline-groove engagement, eliminating the need for separate seal components and fasteners. This merging reduces the number of parts while maintaining both sealing reliability and mounting security.
Solution Approach 2:
The frame structure serves multiple functions: it provides structural support for the filter element, creates the sealing interface with the housing, and enables mechanical retention through the spline-groove mechanism. This multi-functionality consolidates what would traditionally require multiple separate components into a single integrated element, simplifying the overall assembly.
2Reliability
If multiple separate seal components are used, then proper sealing can be achieved, but the manufacturing cost and complexity increases
Solution Approach 1:
The seal function and structural frame are merged into a single elastomeric component. This integration reduces the total number of parts that need to be manufactured, stored, and assembled, thereby lowering manufacturing complexity and cost while maintaining effective sealing through the continuous contact surface of the integrated frame.
Solution Approach 2:
The frame is made from elastomeric material that combines structural integrity with sealing capability. This composite approach allows a single material to provide both mechanical support and sealing function, eliminating the need for separate seal components made from different materials and simplifying the manufacturing process.
3Reliability
If traditional fastening elements and seals are used, then the filter can be securely retained, but the filter exchange during maintenance becomes difficult and time-consuming
Solution Approach 1:
The retention mechanism is segmented into a modular spline-groove interface that allows for tool-free assembly and disassembly. The spline protrusion on the frame engages with the corresponding groove in the housing, creating secure retention while enabling simple lateral movement for filter exchange. This segmented design maintains security during operation while facilitating easy maintenance.
Solution Approach 2:
The elastomeric frame provides dynamic sealing capability that adapts to housing tolerances and wear, maintaining reliable sealing throughout the filter's service life. The material's elasticity allows the frame to deform slightly during installation and operation, ensuring continuous contact with the housing surface for both security and ease of removal.
4Reliability
If complex seal arrangements are used, then proper sealing is ensured, but the handling and installation difficulty increases significantly for users
Solution Approach 1:
The seal element is merged with the frame structure, creating a single handling component rather than separate seal and frame parts. Users handle one integrated piece during installation and maintenance, eliminating the need to separately manage multiple small seal components and reducing installation difficulty while maintaining sealing reliability.
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
Simplifies the installation and maintenance of the motor protection filter by using a single seal element that is easily replaced, reducing complexity and cost while ensuring proper sealing and airflow.
Implementation Method 1
The frame of the filter element is made of an elastic material that simultaneously forms a seal of the motor protection filter relative to the bag compartment lid and relative to the housing of the bag compartment

AI summary
A vacuum cleaner has a lid that selectively opens or closes a filter bag compartment. A secondary motor protection filter is removably mounted in the lid by a frame of an elastic material that simultaneously seals the secondary filter element to the lid and seals the lid onto the bag compartment. An air passage flows between the secondary filter and the lid through a duct to the suction motor compartment. A perimeter groove in the lid receives a spline of the elastic frame of the filter element in a removable manner, while the opposite surface of the frame forms the seal surface relative to a housing rim around the bag compartment.
