Deformable Sealing Design for Efficient Filter Modules
Here’s PatSnap Eureka !
Summary
Problems
Existing filter modules in washing machines face challenges with sealing performance and filter mounting structure, leading to inefficiencies in water management and filtration processes.
Innovation solutions
A filter module design that includes a deformable sealing member, allowing it to be outside the perimeter of the case opening, which deforms under hydraulic pressure to seal the gap between the filter case and the filter, improving sealing performance and mounting efficiency.

Specific contradictions:
General conflict description:
Principle concept:
If a traditional sealing member is used that remains entirely within the case opening perimeter, then the mounting structure is simple, but the sealing performance is insufficient and water leakage occurs
Why choose this principle:
The sealing member is designed as a deformable element that extends beyond the case opening perimeter. When water pressure is applied, the flexible sealing member deforms to conform to the mating surface, creating an effective seal. This flexible membrane approach resolves the contradiction by providing reliable sealing performance while maintaining a relatively simple mounting structure that utilizes the natural deformability of the sealing material.
Principle concept:
If a traditional sealing member is used that remains entirely within the case opening perimeter, then the mounting structure is simple, but the sealing performance is insufficient and water leakage occurs
Why choose this principle:
The sealing member's physical state changes from a rigid or semi-rigid form during installation to a deformed conforming shape under water pressure. This parameter change in the sealing member's deformability allows it to adapt to the mating surface irregularities, improving sealing performance without requiring complex mounting mechanisms or precision machining.

Abstract
A filter module may comprise a filter case having a case opening and an inlet to allow water to enter the filter case, a filter mountable in the filter case through the case opening, and a sealing member that is deformable and is configured so that, with the filter mounted in the filter case, at least a portion of the sealing member is outside a perimeter of the case opening, and with the filter mounted in the filter case and the water entering the filter case through the inlet and thereby causing a hydraulic pressure in the filter case, the sealing member is deformed by the hydraulic pressure so as to seal a gap formed between the filter case and the filter.
