Filtration Filter Device with Removable Tubular Observation Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filtration filter devices make it difficult to observe objects filtered and left on the filtration filter, as they can deform during backwashing or get lost when the filter is removed for observation, and handling thin metallic porous filters is challenging.
Innovation Solution
A filtration filter device with a holding member that secures the outer circumferential portion of the filtration filter and a removably mounted tubular member, allowing for direct observation of the filtered object while maintaining tension and preventing movement, and featuring Luer lock connectors for easy fluid flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the filtration filter is removed for observation, then the filtered object can be observed, but the filtration filter may deform or the object may be lost
Solution Approach 1:
The device is divided into separable components: the holding member that provides stable support and the tubular member that can be removed for observation. This segmentation allows the filtration filter to remain secured during operation while enabling easy removal of the tubular member for observing the filtered object without risking filter deformation or object loss
Solution Approach 2:
The tubular member acts as an intermediary that provides a controlled observation pathway. It allows the filtered object to be viewed through its transparent or translucent wall while the filtration filter remains securely held in place, eliminating the need to remove the filter itself and preventing deformation or object loss
2Measurement precision
If backwashing is performed to observe the filtered object, then the object can be viewed, but the object may deform
Solution Approach 1:
The transparent tubular member serves as an intermediary observation window that allows direct viewing of the filtered object in its natural state on the filtration filter surface. This eliminates the need for backwashing that could deform the object, as the object can be observed through the tubular member wall while remaining undisturbed
Solution Approach 2:
The tubular member is made transparent or translucent, enabling optical observation of the filtered object without physical interference. This optical property allows viewing the object's true state and composition without the mechanical stress of backwashing
3Ease of operation
If a holding member is added to secure the filtration filter, then handling is improved, but device complexity increases
Solution Approach 1:
The holding member integrates multiple functions: it secures the filtration filter during operation, provides structural support for the tubular member, and facilitates easy handling and removal of the entire assembly. This merging of functions achieves improved handling without proportionally increasing complexity
Solution Approach 2:
The holding member serves multiple purposes: anchoring the filtration filter, supporting the tubular member during filtration and observation phases, and enabling easy removal of the tubular member for observation. This multi-functionality improves handling ease while minimizing additional structural complexity
