Solution Overview

Problem

Existing insect breeding systems face issues such as high escape risk during pupae introduction and egg collection, complex geometries that trap flies and complicate cleaning, and non-optimal egg-laying site control, leading to inefficient and difficult maintenance operations.

Innovation Solution

A cage design with smooth transitions and controlled lighting, featuring an emergence airlock and egg collectors with secure access points, along with a group layout for efficient handling and cleaning, reduces escape risks and simplifies maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex geometry with nooks and crannies is used in cage design, then flies may be trapped and containment improved, but cleaning becomes difficult and maintenance operations are complicated

Engineering Contradiction:
Improvefly containmentVSAvoidcleaning ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cage design employs rounded corners and smooth transitions instead of sharp angles and nooks. The curvature of surfaces eliminates trapped areas where flies could hide, making the cage easier to clean while maintaining effective fly containment through smooth continuous surfaces that prevent escape.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Reliability

If complex geometry with multiple nooks and crannies is provided, then flies may be contained, but the risk of laying eggs outside collectors increases

Engineering Contradiction:
Improvefly containmentVSAvoidegg-laying site control
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

Rounded corners and smooth surfaces eliminate nooks and crannies where flies might inadvertently lay eggs. The continuous curved geometry guides flies toward designated egg collection areas, improving precision of egg-laying site control while maintaining containment.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Device complexity

If walls with sharp angles and corners are used, then structural simplicity is achieved, but fly escape risk increases due to trapped areas

Engineering Contradiction:
Improvecage geometryVSAvoidfly containment
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The cage uses rounded corners and smooth transitions throughout its structure. This curvature eliminates sharp angles where flies could become trapped and potentially escape, improving containment reliability while adding only minimal geometric complexity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Reliability

If conventional cage designs are used, then basic containment is achieved, but maintenance operations are not optimal and escape risks remain during pupae introduction and egg collection

Engineering Contradiction:
Improvebasic containmentVSAvoidmaintenance operations
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The rounded geometry eliminates trapped areas during maintenance operations such as pupae introduction and egg collection. Smooth surfaces prevent fly escapes during these operations and make cleaning more efficient, significantly improving ease of operation while maintaining containment.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A cage for the industrial production of insect eggs made up of an enclosure delimited by a ceiling and four side walls defining a confined box-shaped space for the insects, the enclosure containing an area for accommodating at least one container of pupae and means for attaching and extracting collectors for collecting the eggs laid by the insects confined in the cage, characterised in that the front wall of the enclosure has at least one first opening that can be closed by a first door for accessing the area for accommodating at least one container of pupae, a second door for enabling an operator to access the inside of the cage, at least one opening lined with additional closure means for inserting and removing the egg collectors; the cage having a dark inner space that communicates, on the one hand, with the first door and, on the other hand, with the rest of the enclosure.
