Solution Overview
Problem
Conventional filtration techniques often compromise the integrity of microscopic specimens during transfer from filters to slides, leading to material loss, contamination, and potential damage, which hinders effective microscopic examination.
Innovation Solution
A filtration system and method that allows for direct application of a filter containing the filtrand onto a microscope slide, eliminating the need for separate filtration and slide preparation, and incorporating a microscope slide with integrated filtration capabilities to facilitate controlled filtration and subsequent microscopic examination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional filtration techniques are used with separate filters and slides, then filtration can be performed, but material loss and contamination occur during transfer
Solution Approach 1:
The patent combines the filter and microscope slide into a single integrated unit. The filter is mounted directly on the microscope slide, eliminating the need for separate transfer steps. This merging of components allows the filtrand to remain on the filter while the entire assembly is placed under the microscope, preventing material loss and contamination that would occur during transfer between separate components.
2Reliability
If mechanical removal of filtrand from filter to slide is performed, then examination can proceed, but specimen integrity is compromised
Solution Approach 1:
By integrating the filter directly onto the microscope slide, the invention eliminates the mechanical removal and transfer process entirely. The filtrand remains in situ on the filter, and the combined filter-slide assembly is simply placed on the microscope stage. This approach maintains specimen integrity by avoiding mechanical handling that could damage or contaminate the sample, while still enabling microscopic examination.
3Productivity
If controlled differential pressure is applied during filtration, then filtration efficiency improves, but equipment complexity increases
Solution Approach 1:
The integrated filter-slide design allows for simple application of differential pressure using the microscope stage itself or basic vacuum/adhesion mechanisms. The filter adheres to the slide through adhesion forces, and pressure control can be achieved through simple means such as placing the assembly on an inclined surface or using minimal vacuum, avoiding complex pressure control systems while maintaining filtration efficiency.
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
This approach minimizes material loss, prevents contamination, and ensures the integrity of the specimen during examination, enabling efficient and effective microscopic analysis across various microscopy techniques, including optical and electron microscopy.
Implementation Method 1
Filters are devices, often in the form of a membrane or layer, that are designed to physically block certain objects or substances while letting other objects or substances through
Implementation Method 2
the application of a controlled differential pressure between the input and output sides of the filter may significantly impact the filtration process
