Movable Crate Ventilation Layout for Insect Rearing Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect rearing/breeding housings face challenges in providing uniform ventilation to individual crates, necessitating dedicated nozzles, which is inefficient and costly.
Innovation Solution
The design features crates with holes in the bottom allowing air intake and discharge through housing openings, supported for movement between insertion and discharge openings, with longitudinal flanges preventing escape and enhancing ventilation flow using curtains and alternating air supply through top and bottom openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dedicated nozzles are provided for each crate, then uniform ventilation to individual crates is achieved, but device complexity and cost increase
Solution Approach 1:
The bottom of the housing serves multiple functions: it acts as the structural base, the ventilation air intake source, and the support surface for crates. This eliminates the need for separate dedicated nozzles for each crate, achieving uniform ventilation through a single universal air intake structure while reducing device complexity
Solution Approach 2:
The ventilation system is merged with the housing structure itself. The bottom opening serves as both the structural base and the air intake, combining what were previously separate components (housing base and ventilation nozzles) into a single integrated structure, thereby reducing complexity while maintaining uniform ventilation
2Ease of operation
If crates are made movable for easy handling, then ease of operation improves, but reliability of containing insects may worsen
Solution Approach 1:
Longitudinal flanges serve as an intermediary element between the movable crates and the fixed housing. These flanges provide a mechanical connection that allows crates to be moved in and out while simultaneously acting as a barrier to prevent insects from escaping, thus resolving the contradiction between ease of operation and reliability
Solution Approach 2:
The housing is segmented into movable crate portions and fixed housing portions connected by longitudinal flanges. This segmentation allows the crates to be independently moved for handling while the flange connections maintain containment integrity, separating the functions of movement and containment
3Productivity
If air is supplied through bottom openings, then ventilation efficiency improves, but harmful factors (odors) may increase
Solution Approach 1:
The ventilation system operates continuously with air constantly flowing through the bottom openings and through the crates. This continuous air flow prevents odor accumulation by constantly replacing stale air with fresh air, maintaining ventilation efficiency while preventing harmful odor buildup in the housing
Solution Approach 2:
The system uses pneumatic principles to create continuous air flow through the bottom openings and through the crates. This pneumatic action drives fresh air through the rearing area and exhausts harmful odors, maintaining efficient ventilation while preventing odor accumulation
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
Ensures even air distribution and prevents insect escape, maintaining a clean environment for continuous operation by removing odors and facilitating easy crate handling and population separation.
Implementation Method 1
holes formed in the bottom of the crates allow for air to be sucked into the housing and to be discharged through at least one air ventilating opening of the housing
Data Source
AI summary
An insect rearing/breeding housing, wherein a plurality of crates arranged in a row along the length of the housing define at least a portion of the housing bottom. Holes formed in the bottom of the crates allow for air to be sucked into the housing and to be discharged through at least one air ventilating opening of the housing. The housing having a crate insertion opening in at least one end and a crate discharge opening at the housing bottom. The crates being supported so as to be movable from said insertion opening to the discharge opening.
