Solution Overview

Problem

Current systems for large-scale production of insect larvae, such as black soldier fly (BSF), face challenges in optimizing the insect life cycle stages, particularly in inducing mating behaviors and efficiently collecting and isolating eggs while maintaining controlled environmental conditions for bioconversion processes.

Innovation Solution

A mechanized system comprising a mating chamber and a bioconversion unit, where adult insects mate to produce eggs, which are then transferred for larval rearing, with controlled environmental conditions and metered introduction and collection of inputs and outputs, optimizing space use and life cycle stages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If adult insects are housed in confined spaces to optimize space use, then space efficiency is improved, but mating behavior induction and egg collection efficiency deteriorate

Engineering Contradiction:
Improvespace efficiencyVSAvoidegg production and collection efficiency
Core Design Contradiction:
Area of moving objectVSProductivity

Solution Approach 1:

The mating chamber is divided into multiple compartments that can be independently accessed. Each compartment contains adult insects and can be separately serviced for egg collection, allowing continuous operation without moving entire populations. This segmentation enables efficient space use while maintaining access for egg harvesting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A removable tray system acts as an intermediary between the confined mating chamber and the external environment. The tray can be easily removed for egg collection and replacement, mediating between the need for confined space and the need for efficient egg harvesting without disrupting the insect population.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If controlled environmental conditions are maintained to optimize life cycle stages, then productivity is improved, but system complexity increases

Engineering Contradiction:
Improvelarval growth rates and egg productionVSAvoidenvironmental control system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system uses simple physical adjustments to environmental parameters (temperature, humidity, light cycles) rather than complex automated control systems. By manually adjusting these parameters to optimal ranges for different life cycle stages, the system achieves high productivity without requiring sophisticated control mechanisms.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The mating chamber design allows the insect population to self-regulate to some extent through natural behaviors. The confined space and provided resources enable insects to naturally cycle through metamorphosis stages, reducing the need for external intervention and complex control systems while maintaining optimal development conditions.

Inventive Principle:
Principle #25Self-service

3Productivity

If metered introduction and collection of inputs and outputs is implemented, then productivity and resource efficiency are improved, but operational complexity increases

Engineering Contradiction:
Improveresource efficiency and output optimizationVSAvoidoperational simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system pre-calculates and pre-prepares the required inputs (substrate, water, food) in measured quantities before introducing them to the mating chamber. This preliminary measurement and preparation simplifies ongoing operations by eliminating the need for continuous monitoring and adjustment, while still achieving metered resource use for optimized productivity.

Inventive Principle:
Principle #10Preliminary action

AI summary

Methods and apparatus are provided for culturing Dipteran insects, particularly Hermetia illucens. The apparatus include a mating chamber that contains adult insects, and adaptations for the scheduled and/or metered introduction of inputs, such as: empty egg laying substrate, prepupae, bedding, carbohydrate (sugar) and/or water); and, the scheduled and/or metered collection of outputs, such as: egg laying substrate containing eggs, exuvia and bedding, and/or dead adults. The systems may also include adaptations to optimize the use of space, including the use of controlled environmental conditions within a confined space.
