Rotating Filter Panel Structure for Contamination-Safe Animal Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for breeding laboratory animals face challenges in easily replacing and stably disposing of filters, leading to potential gaps that allow contaminated air to enter the breeding space.
Innovation Solution
The apparatus is designed with a filter unit where the upper panel rotates upward, allowing easy replacement and stable fixation of the filter between the lower and upper panels, along with a temperature display sticker and a color-changing clamping member for sterilization verification, facilitating easy animal insertion/removal and connection to air conditioners and various feeders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is designed to be easily replaceable, then the ease of operation is improved, but the stability and reliability of filter fixation deteriorates, leading to potential gaps and air contamination
Solution Approach 1:
The filter unit is divided into separate components: a filter holder fixed to the apparatus main body, and a detachable filter element. This segmentation allows the filter to be easily replaced by simply removing the filter element from the holder, while the holder itself remains securely fixed to maintain sealing integrity and prevent gaps during operation.
2Ease of repair
If the filter unit structure is simplified for easy maintenance, then the ease of repair is improved, but the device complexity increases due to additional components needed for stable fixation
Solution Approach 1:
The filter element is extracted as a separate, independently replaceable component from the filter holder. This allows the filter to be removed and replaced without disassembling the holder or other structural components, simplifying maintenance while the holder provides the necessary structural integrity and fixation stability.
3Reliability
If the filter is securely fixed to prevent gaps, then the reliability is improved, but the ease of operation for filter replacement deteriorates
Solution Approach 1:
The system is segmented into a permanently fixed holder that ensures sealing integrity and a separately replaceable filter element. The holder remains securely attached to the apparatus main body to prevent gaps, while the filter element can be easily removed and replaced without compromising the holder's fixation stability.
