Solution Overview
Problem
Existing devices for filtering small quantities of liquid are cumbersome, require elaborate packaging, and involve time-consuming filter changes, making them inefficient and material-intensive.
Innovation Solution
A two-part device design with a first part for receiving a pipette tip and a second part containing a filter, allowing for easy assembly and disassembly, compatible with different pipette sizes, and featuring a stable connection mechanism and elastic material for secure fitting into reaction vessels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional syringes with filters are used, then liquid filtration is achieved, but filter changes are time-consuming and device complexity increases
Solution Approach 1:
The device is divided into a first part (body) and a second part (filter unit), allowing the filter to be easily replaced by simply detaching and attaching the second part, significantly reducing filter change time while maintaining filtration functionality
Solution Approach 2:
The second part with the filter is designed to be inserted into and nested within the first part, creating a compact integrated structure that simplifies the overall device while enabling quick filter changes through simple insertion and removal actions
2Reliability
If elaborate packaging is used for prior art devices, then protection and stability are improved, but material consumption and device complexity increase
Solution Approach 1:
The device is provided as separate first and second parts that can be packaged independently, reducing the need for elaborate protective packaging while maintaining device integrity during transport and storage
Solution Approach 2:
The first part is designed as a universal body that can accommodate different second parts with filters, reducing the need for device-specific packaging and allowing standardized protective measures to be applied to multiple device configurations
3Ease of operation
If a two-part device design is used, then ease of operation and adaptability are improved, but device complexity increases
Solution Approach 1:
The second part is inserted into the first part to form an integrated filtering device, creating a simple unified structure during use while maintaining the advantage of separable components for easy cleaning and filter replacement
Solution Approach 2:
The first part and second part are designed to combine into a single functional unit with integrated filtration capability, providing the simplicity of a single-device operation while retaining the flexibility of modular components
