Solution Overview

Problem

Current fly maggot culture methods, such as box-type, cage-type, and frame-type culturing, are labor-intensive and inefficient, limiting large-scale and high-efficiency production, and require manual feeding and separation processes that are time-consuming and costly.

Innovation Solution

A large-scale and high-efficiency fly maggot culture equipment with automated feeding and separation systems, including a feeder traveling along rails, a rail car, a temperature-controlled culturing bed, and an automated fly maggot separator, which reduces labor intensity and enhances production efficiency by integrating feeding and culturing processes and maintaining optimal environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated feeding system is implemented, then feeding efficiency is improved and labor intensity is reduced, but device complexity increases

Engineering Contradiction:
Improvefeeding efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automated feeding system enables the culturing equipment to feed fly maggots automatically without human intervention. The feeder travels along rails and distributes biomass waste to culturing beds autonomously, allowing the system to serve itself and eliminating manual feeding operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical feeding operations with an automated mechanical system. The feeder equipped with biomass waste distributors travels along burden distributing rails and automatically dispenses feed material to multiple culturing beds, substituting human labor with automated mechanical action.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If automated fly maggot separator is used, then separation efficiency is improved and labor intensity is reduced, but device complexity increases

Engineering Contradiction:
Improveseparation efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The fly maggot separator automatically separates fly maggots from compost residue without manual intervention. The system uses vibrating screens or other separation mechanisms that operate autonomously, allowing the equipment to perform the separation function itself without requiring workers to manually sort maggots.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual separation operations with automated mechanical separation systems. The separator uses mechanical means such as vibrating screens, conveyors, or sorting mechanisms to automatically separate fly maggots from compost, substituting human manual sorting with automated mechanical processes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If temperature-controlled culturing bed is implemented, then fly maggot growth efficiency is improved, but energy consumption increases

Engineering Contradiction:
Improvefly maggot growth efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The temperature-controlled culturing bed maintains optimal temperature parameters for fly maggot growth. By controlling the temperature parameter within the culturing bed, the system creates ideal conditions for accelerated maggot development and growth, directly improving productivity through parameter optimization.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The heating elements in the culturing bed utilize thermal conduction to distribute heat evenly throughout the biomass waste and maggot culture medium. The thermal energy expands and distributes through the culture material, maintaining consistent temperatures that promote efficient maggot growth while managing energy consumption.

Inventive Principle:
Principle #37Thermal expansion

4Productivity

If large-scale culturing equipment is used, then production capacity is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveproduction capacityVSAvoidease of operation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The large-scale culturing equipment is divided into multiple independent modules including separate culturing beds, feeding stations, and separation units. Each module can be operated and maintained independently, making the large-scale system manageable through functional segmentation rather than requiring control of a monolithic complex structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rail car and feeder system serve multiple functions: they transport biomass waste to multiple culturing beds, distribute feed material automatically, and can service different zones of the facility. This multi-functionality reduces the number of separate systems needed, simplifying operation despite the large scale of production.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention provides a set of large-scale and high-efficiency fly maggot culture equipment and a large-scale and high-efficiency fly maggot culture process and pertains to fly maggot culture. The equipment comprises at least one culturing workshop with a multi-functional ceiling. At least one feeder traveling along double-row burden distributing rails is arranged in the culturing workshop. A pair of main rails is perpendicularly arranged on the front of one ends of the burden distributing rails. A rail car used for transferring the feeder among different burden distributing rails is arranged on the main rails. Transferring rails horizontally perpendicular to the main rails are arranged on the rails car. The height of the transferring rails is consistent with the height of the distributing rails. The workshop ground between the two rails of the distributing rails form a culturing bed for fly maggot culture. The equipment also includes a central control apparatus connected with an alarm and a fly maggot separator. The equipment and the process provided in this present invention can realize incessant fly maggot flow line culture, without being affected by temperature, and is much highly automatic to realize fly maggot production in large scale and with high effectiveness.
