Separate Bottle Top Filter Device with Removable Membrane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter devices have integral funnels with filters, making it necessary to replace the entire device if a fault occurs, and the filters are not easily replaceable.
Innovation Solution
A separate type bottle top filter device is designed with first and second coupling bodies and a membrane filter, allowing for removable coupling and easy replacement of faulty parts and filters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a funnel with filter is integrally formed, then the structure is simple and easy to manufacture, but the entire device must be replaced when a fault occurs and the filter is not easily replaceable
Solution Approach 1:
The filter device is divided into separate components: a funnel body and a filter element. The filter element can be removed from the funnel body through a opening, allowing the filter to be replaced independently without replacing the entire funnel assembly. This segmentation enables easy repair while maintaining manufacturing simplicity.
2Device complexity
If a funnel with filter is integrally formed, then the structure is simple, but the entire device must be replaced when a fault occurs
Solution Approach 1:
The device is segmented into a reusable funnel body and a replaceable filter element. When the filter fails, only the filter element needs replacement, not the entire funnel, thereby improving reliability without significantly increasing device complexity.
Solution Approach 2:
The filter element is extracted as a separate, removable component from the funnel body. This extraction allows the filter to be independently replaced when faulty, preventing the need to discard the entire funnel assembly and thus improving overall device reliability.
3Device complexity
If the filter is not easily replaceable, then the device structure is simple, but the time to replace the filter is long
Solution Approach 1:
The filter is segmented as a separate element that can be independently removed from the funnel body. This segmentation enables quick filter replacement without disassembling the entire device, thereby reducing the time lost to filter replacement while keeping the overall device structure relatively simple.
