Breeding Apparatus Filter Separation for Air Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laboratory animal breeding apparatuses face issues such as animal mortality due to air stagnation when air conditioning fails, inconvenience in animal handling and air conditioning system connection, and limited feed container shapes.
Innovation Solution
The apparatus includes a filter separably attached to the cover, a water supply system with a rotary opening mechanism, and a feed container with a mesh design, allowing for easy animal handling, air circulation, and versatile feed container shapes, with features like magnetic force assistance for air flow management and elastic sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air conditioning equipment is provided to circulate air in the breeding space, then air quality is improved, but the apparatus becomes more complex and requires external system connection
Solution Approach 1:
The patent incorporates a filter directly into the cover structure that can function as a backup air purification system. This pre-built filter provides a safety mechanism that activates when the external air conditioning system fails, cushioning against the harmful effect of air stagnation without requiring complex external connections.
Solution Approach 2:
The filter acts as an intermediary element between the breeding space and the external environment. It can work in conjunction with the air conditioning system when available, and independently when the system fails, mediating the air quality requirement without requiring direct connection to external infrastructure.
2Stability of the object's composition
If the cover is made fixed and sealed, then sealing performance is improved, but animal handling becomes inconvenient
Solution Approach 1:
The cover is segmented into a main cover body and a separable filter component. The filter can be removed independently to access the breeding space for animal handling, while the main cover remains sealed. This segmentation allows the sealing function and accessibility function to operate independently without compromising either.
3Ease of manufacture
If a single shape feed container is provided, then device complexity is reduced, but adaptability is limited
Solution Approach 1:
The cover structure with its integrated filter and opening mechanism serves multiple functions: it provides sealing, allows animal access, supports various feed container shapes, and incorporates air filtration. This multi-functionality compensates for the simplicity of having a single cover design, providing versatility without increasing overall device complexity.
