Isofucosterol Pollen Substitute for Sustained Bee Brood Production

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current artificial diets for bees are incomplete, leading to rapid decline in brood production after 3-4 cycles due to lack of essential nutrients, and there is a need for a pollen-free feed that can sustain bee colonies long-term without natural pollen sources.

Innovation Solution

A pollen substitute composition containing isofucosterol and a combination of sterols such as cholesterol, 24-Methylenecholesterol, campesterol, beta-sitosterol, and stigmasterol is administered to provide the necessary nutrients for sustained brood production and colony development.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a pollen-free artificial diet is used for bees, then the feed can be produced without pollen collection costs and stored without freshness issues, but the diet is incomplete and causes rapid decline in brood production after 3-4 cycles

Engineering Contradiction:

Improvefeed production and storageVSAvoidbrood production sustainability

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent applies parameter changes by precisely adjusting the concentrations and ratios of multiple sterols in the artificial diet. Specifically, it optimizes the content of isofucosterol, cholesterol, campesterol, beta-sitosterol, and stigmasterol to match natural pollen composition, enabling the diet to support continuous brood production for more than 4 cycles without the rapid decline seen in previous formulations

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by combining multiple sterols in specific proportions rather than using a single sterol or simple mixture. The diet comprises a complex composition of at least five different sterols (isofucosterol, cholesterol, campesterol, beta-sitosterol, stigmasterol) with optimized ratios that collectively provide complete nutritional support for bee brood development, replacing the insufficient single-sterol or limited-sterol formulations of the past

Inventive Principle:

Principle #40Composite materials

2Reliability

If natural pollen is collected for bee feed, then the diet contains essential nutrients for sustained brood production, but pollen collection is costly, difficult to keep fresh, and can carry pests and diseases

Engineering Contradiction:

Improvenutritional completenessVSAvoidpests, diseases, and contamination

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the extraction principle by isolating and purifying the essential nutritional components (multiple sterols) from natural pollen to create a concentrated, pure artificial diet formulation. This extraction process removes harmful contaminants (pests, diseases, pesticides) while retaining the beneficial sterols needed for brood production, achieving both nutritional completeness and safety

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses copying by replicating the sterol composition profile of natural pollen in an artificial medium. Instead of using actual pollen, the diet copies the essential sterol ratios and concentrations found in natural pollen (isofucosterol 10-50%, cholesterol, campesterol, beta-sitosterol, stigmasterol), creating a synthetic equivalent that provides the same nutritional benefits without the associated risks

Inventive Principle:

Principle #26Copying

3Device complexity

If single sterols are added to artificial diets, then the formulation is simpler, but the diet remains incomplete and cannot support long-term brood production

Engineering Contradiction:

Improvediet formulation complexityVSAvoidbrood production duration

Core Design Contradiction:

Device complexityVSDuration of action of stationary object

Solution Approach 1:

The patent applies merging by combining multiple individual sterols into a unified diet formulation. Rather than using single sterols separately, the patent integrates at least five different sterols (isofucosterol, cholesterol, campesterol, beta-sitosterol, stigmasterol) into a single composite diet that works synergistically to support continuous brood production for more than 4 cycles, overcoming the limitations of single-sterol approaches

Inventive Principle:

Principle #5Merging (Combining)
