Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport devices for insect larvae and eggs are inadequate for safely transporting larvae with varying age groups and do not allow for simultaneous transport of different age groups, and there is a lack of reliable methods to maintain optimal climatic conditions during transport.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple transport container is used, then the device complexity is reduced, but the reliability of larval survival during transport deteriorates
Solution Approach 1:
The transport device is divided into multiple independent compartments, each capable of maintaining separate climatic conditions. Each compartment contains larval containers with individual ventilation and exhaust openings, allowing differentiated environmental control for different larval age groups while using a relatively simple overall structure.
Solution Approach 2:
Different regions of the transport device provide different environmental conditions. Younger larvae in certain compartments receive different temperature, humidity, or gas composition compared to older larvae in other compartments. This local differentiation of environmental quality enables simultaneous transport of multiple age groups with varying requirements.
2Device complexity
If a single transport container is used, then the device complexity is reduced, but the adaptability to different larval age groups deteriorates
Solution Approach 1:
The transport device employs multiple separable compartments that can be independently configured. Each compartment can be tailored to specific larval age group requirements through adjustable ventilation and exhaust openings, enabling the same basic structure to adapt to different transport scenarios.
Solution Approach 2:
The transport device is designed as a universal system that can accommodate various larval age groups simultaneously. The standardized compartment design with adjustable environmental controls allows the same device structure to serve multiple functions - transporting different species, different age groups, or different quantities of larvae according to specific needs.
3Reliability
If climate control systems are added, then the reliability of larval survival is improved, but the device complexity increases
Solution Approach 1:
The climate control system utilizes passive mechanisms where larval metabolic activity itself generates heat and CO2, which naturally drive convection currents through the ventilation and exhaust openings. The system self-regulates to some extent based on larval activity levels, reducing the need for complex active control mechanisms while maintaining reliable environmental conditions.
Solution Approach 2:
The climate control is achieved through carefully designed ventilation and exhaust openings that utilize gas flow dynamics. By controlling opening sizes and positions, the system regulates air exchange, CO2 removal, and humidity control through pneumatic principles rather than complex mechanical or electronic systems.

AI summary
A mobile transport device for transporting insect larvae includes a housing having a selectively openable and closable opening and a receiving section within the housing for receiving at least one first insect fattening container. The first insect fattening container accommodates a first insect larvae cohort for fattening, a recirculation fan for partially recirculating air within the housing, an electronic control unit for controlling the recirculation fan, and a first air regulating device having a first ventilation section on a first side and a first exhaust section on a second side. Air enters the first insect fattening container through the first ventilation section and exits the first insect fattening container through the first exhaust section using the recirculation fan.
