    "title": "Flow Hive - Harm-Free Honey Extraction",
    "inventor_name": "Cedar Anderson; Stuart Anderson",
    "publication_year": 2019,
    "device_name": "Flow Hive",
    "goal": "Enable honey to be harvested without removing the honeycomb, reducing labor and minimizing harm to bees.",
    "problem_addressed": "Traditional honey extraction is labor-intensive, harms bees, requires removal of combs, and can damage the hive.",
    "concept_summary": "The Flow Hive uses a movable-frame honeycomb where side and end walls can be separated inside the hive, allowing honey to flow out by gravity into a collection trough. The comb remains in place, eliminating the need for uncapping, centrifuging, or frame removal.",
    "detailed_description": "The invention comprises a honeycomb formed of at least two parts that move relative to each other. In the closed position the cells are sealed by side walls and an end wall so bees can fill them with honey. When the beekeeper actuates the frame, the walls separate, opening the cells and permitting honey to drain out of the hive into a collection system. The device can be built from plastic (polypropylene) or aluminium frames with wax or plastic sheet foundations. It operates without external power, relying on manual actuation and gravity.",

    "experimental_evidence": "Prototype videos and field demonstrations show honey flowing out of the opened cells; the product has been sold to thousands of beekeepers worldwide.",
