Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional kitchen sink drain strainers often become clogged with debris, leading to water backup and are difficult to clean.
Innovation Solution
A drain strainer with a rigid base and a flexible, elastic membrane that allows water to flow while trapping debris, which can be easily wiped away or released by stretching the membrane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional strainer basket is used, then debris can be trapped, but the strainer becomes difficult to clean and clogs easily
Solution Approach 1:
The strainer membrane transitions from a static rigid structure to a dynamic flexible structure that can be stretched and deformed. The flexible membrane allows users to stretch it outward to dislodge and remove accumulated debris easily, then returns to its original position to continue straining, making cleaning simple while maintaining effective debris trapping
Solution Approach 2:
The invention replaces the traditional rigid basket structure with a flexible thin film membrane that has integrated perforations. This flexible membrane can be stretched to facilitate debris removal and naturally returns to its original configuration, providing both effective straining and easy cleaning without requiring complex support structures or handles
2Stability of the object's composition
If a rigid strainer basket is used, then structural stability is maintained, but water flow is restricted and backup occurs
Solution Approach 1:
The flexible membrane structure allows the strainer to maintain a stable flat configuration during normal operation for effective straining, while enabling water to flow through the integrated perforations. When debris accumulates, the membrane can be stretched without structural resistance, allowing easy debris removal and restoring full water flow capability without backup
Solution Approach 2:
The membrane incorporates integrated perforations that allow water to pass through while trapping debris. The porous structure maintains structural stability in its flat state for effective straining, yet permits unrestricted water flow through the perforations, preventing backup while maintaining straining functionality
3Ease of operation
If complex support structures and handles are added, then ease of cleaning is improved, but device complexity increases
Solution Approach 1:
The invention extracts and eliminates the need for complex support structures, handles, and basket frameworks by using a simple flexible membrane with integrated perforations. The membrane's inherent flexibility provides the cleaning functionality that would otherwise require additional mechanical components, achieving easy debris removal with minimal structure
Solution Approach 2:
The flexible membrane serves multiple functions simultaneously: it strains debris through its perforations, allows water flow, and can be stretched to facilitate cleaning. This multi-functional design eliminates the need for separate components like handles and support structures, achieving ease of cleaning without increasing device complexity
