Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If neonate larvae are transported using conventional conveyors, then transport efficiency is improved, but larvae loss increases due to scattering and damage

Engineering Contradiction:
Improvetransport efficiencyVSAvoidlarvae loss
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The conveyor system is divided into multiple sections with different functions: a first conveyor for initial transport, a second conveyor for concentration, and a third conveyor for final transport. This segmentation allows each section to optimize for its specific task, reducing overall larvae loss while maintaining transport efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A concentration chamber is introduced as an intermediary element between the first and second conveyors. This chamber acts as a mediator that collects scattered larvae and redirects them to the appropriate conveyor, preventing loss and ensuring continuous efficient transport.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If larvae are concentrated using mechanical means, then homogeneity is improved, but energy consumption increases

Engineering Contradiction:
Improvelarvae homogeneityVSAvoidenergy consumption
Core Design Contradiction:
Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The concentration chamber is designed to allow larvae to concentrate naturally through gravity and flow dynamics rather than requiring active mechanical agitation. The chamber geometry creates conditions where larvae self-organize into homogeneous groups, achieving concentration without additional energy input.

Inventive Principle:
Principle #12Equipotentiality

Solution Approach 2:

The system allows larvae to perform the concentration function themselves by utilizing their natural movement patterns and the chamber's geometric constraints. The flared walls and specific angle designs guide larvae to concentrate automatically, eliminating the need for external energy-consuming concentration mechanisms.

Inventive Principle:
Principle #25Self-service

3Device complexity

If egg collectors are fixed in position, then system simplicity is improved, but adaptability decreases for different production volumes

Engineering Contradiction:
Improvesystem simplicityVSAvoidproduction volume flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The egg collector is designed with movable and adjustable components, including the ability to change the angle of the collector relative to the conveyor and the positioning of flared walls. These dynamic adjustments allow the same system to handle varying production volumes efficiently without requiring complete system redesign.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows modification of key geometric parameters such as the angle of the egg collector, the dimensions and positioning of flared walls, and the conveyor speed ratios. By changing these parameters, the system can adapt to different production requirements while maintaining the same basic structure.

Inventive Principle:
Principle #35Parameter changes

AI summary

The invention relates to an installation for producing and collecting newly-hatched larvae, comprising a collection of cages equipped with at least one collector (560) of eggs laid by the insects present in the cages, a line for transferring the larvae newly hatched from the hatched eggs from each of the collectors (560) to a conveyor, and equipment for concentrating the newly-hatched larvae coming from the conveyor in order to convey them to an insect-raising module or to a newly-hatched-larvae buffer storage container. It also comprises: • a collection of modules (500, 501) grouping together a plurality of egg collectors (560), said modules (500, 501) being open at their bottom; • said modules (500, 501) being mobile between a point of loading with the collectors removed from the cages and the newly-hatched-larvae transfer line; • said newly-hatched-larvae transfer line being open, with no casing at the top, in order to receive the modules (500, 501) at the top, and at the bottom having a guide system with divergent walls (123, 124; 173, 174), referred to as a receptacle, which at its top has a width tailored to the cross section of the modules and at its bottom has an opening (125, 175) tailored to the dimensions of a conveyor (110, 160), said receptacle being configured to group together the newly-hatched larvae falling under the effect of gravity from the collectors (560) onto the upper surface of the conveyor.
