Drainage Sieve With Movable Closure Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drainage sieves in water basins are ineffective in retaining smaller dirt particles like food scraps and hair, leading to clogging and are difficult to clean due to their fixed position and large openings.
Innovation Solution
A drainage sieve with a tubular closure part and sieve part that can be moved relative to each other, allowing for easy insertion, opening, and closing, with a guide element that facilitates linear or rotational movement to control the flow of water and retain debris, and a design that allows for gravity-assisted closure without additional force requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed sieve with large openings is used in the drain, then large particles can be retained, but smaller dirt particles pass through and cause clogging
Solution Approach 1:
The drainage sieve is divided into two functional parts: a fixed sieve part with larger openings for retaining big particles, and a movable closure part with smaller openings for filtering fine particles. This segmentation allows each part to specialize in different particle sizes, solving the contradiction between retaining large particles and blocking small particles.
Solution Approach 2:
The closure part is made movable relative to the sieve part, allowing it to be positioned in different locations. When positioned over the sieve openings, it filters fine particles; when removed, it allows free drainage. This dynamic positioning resolves the contradiction by enabling the system to adapt its filtering capability based on operational needs.
2Ease of manufacture
If a fixed drain sieve is located deep below the basin bottom, then it can be installed in conventional drains, but it becomes difficult to clean
Solution Approach 1:
The drainage sieve is segmented into a fixed sieve part that remains in the drain and a removable closure part. The closure part can be easily removed and cleaned separately, while the sieve part stays installed in the conventional drain. This segmentation resolves the contradiction by making the cleaning-accessible component removable while maintaining installation compatibility.
Solution Approach 2:
The closure part is extracted as a separate, removable component from the fixed sieve structure. This allows the closure part to be taken out for easy cleaning and maintenance without disturbing the installed sieve part in the drain, solving the accessibility problem while maintaining conventional installation requirements.
3Object-affected harmful factors
If small sieves are inserted into the fixed drain, then they can filter particles, but they are narrower, clog more quickly, and are difficult to clean
Solution Approach 1:
The filtering function is segmented between the fixed sieve part (handling large particles) and the movable closure part (handling fine particles). The closure part has a larger diameter than traditional small sieves, reducing clogging frequency, while its movable nature enables easy removal for cleaning, resolving all three issues simultaneously.
Solution Approach 2:
The closure part's movable design allows it to be dynamically removed and repositioned. This dynamic capability enables easy cleaning by simply lifting the closure part out, and prevents clogging by allowing complete removal when blocked, unlike fixed narrow sieves that are difficult to access and clean.
