Transformable Gully Filter for Compact Inlet Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gullies face challenges with limited component size due to inlet constraints, cumbersome maintenance, and difficulty in locating and positioning cleaning hoses, leading to inefficient filtering and cleaning processes.
Innovation Solution
A transformable filter for gullies that can change from an insertion state to a mounting state, allowing for a larger filtering area without increasing the inlet size, and features like a flexible material, expandable parts, and access points for easy cleaning and hose guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the filter is made larger to increase filtering area, then filtering efficiency is improved, but the filter cannot be inserted through the gully inlet
Solution Approach 1:
The filter is designed with transformable geometry that allows it to change shape between insertion and mounting states. During insertion, the filter adopts a compact configuration that fits through the inlet, and after insertion, it transforms to an expanded configuration that provides large filtering area when mounted in the gully pot.
Solution Approach 2:
The filter components are designed to nest within each other during the insertion state, allowing the filter to be compacted to fit through the inlet. Once inserted, the nested components are deployed or expanded to achieve the full filtering area in the mounted state.
2Volume of moving object
If the gully inlet is made larger to accommodate larger components, then component size capacity is improved, but the gully structure becomes more complex and less safe
Solution Approach 1:
The filter dynamically changes its size after insertion, allowing a small inlet to accommodate a large filtering component. The filter is inserted in a compact state through the standard-sized inlet, then transforms to a larger state once inside the gully pot, eliminating the need for larger inlets or more complex gully structures.
3Ease of repair
If the filter is made removable for easy maintenance, then ease of repair is improved, but the filter may become lost or misplaced
Solution Approach 1:
The filter incorporates engagement features that interact with the gully pot structure to secure the filter in place. These engagement features allow the filter to be easily removed for maintenance while preventing accidental loss or misplacement during normal operation, acting as an intermediary mechanism between removability and retention.
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
Enhances filtering efficiency and simplifies maintenance by enabling larger filters and easier cleaning access, while maintaining compactness and safety through transformable designs.
Implementation Method 1
The filter is transformable from an insertion state to a mounting state. The mounting state is for mounting the filter in the gully pot. The insertion state is for inserting the filter through the inlet from outside of the gully or gully part and/or for removing the filter from the gully or gully part through the inlet.
