Embedded Heating Brood Comb for Varroa Mite Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for combating Varroa mites in bee colonies, such as chemical treatments and thermal treatments in separate heating cabinets, are either risky, costly, or ineffective in protecting the entire bee colony, especially the worker bee brood cells.
Innovation Solution
A device with a central wall embedded with a resistance heating element and a control system that heats the brood cells for female bees to a temperature of 39°C to 45°C for a predetermined time, allowing for automatic and controlled heating processes without removing the brood comb from the hive, ensuring the Varroa mites are killed while the bees remain unharmed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical treatment is used to combat Varroa mites, then the effectiveness against mites is improved, but the risk of residues contaminating honey increases
Solution Approach 1:
The patent changes the parameter of treatment method from chemical to thermal. By heating the brood comb to temperatures between 39-42°C for several hours, the patent achieves effective mite control through temperature parameter change, eliminating the need for chemical substances and thus avoiding honey contamination while maintaining reliability in combating Varroa mites.
2Object-affected harmful factors
If separate heating cabinet is used for thermal treatment, then the safety from chemical residues is improved, but the time consumption and investment cost increase
Solution Approach 1:
The patent merges the heating function directly into the brood comb structure by embedding heating elements within the comb itself. This integration eliminates the need for separate heating cabinets and the associated time-consuming process of moving brood combs in and out. The brood comb becomes both the object to be heated and the heating device, thereby maintaining safety from chemical residues while significantly reducing time loss.
Solution Approach 2:
The brood comb is equipped with self-heating capability through embedded heating elements, allowing it to treat itself against Varroa mites without requiring external heating cabinets or manual intervention to move the combs. This self-service approach maintains the safety benefit of thermal treatment while eliminating the time-consuming handling operations.
3Ease of operation
If heating device is provided only in drone brood comb, then the ease of operation is improved, but the protection coverage for worker bees is reduced
Solution Approach 1:
The patent makes the heating device universal by providing it in all brood combs, not just drone brood combs. This multi-functional application ensures that both worker bee brood and drone brood receive protection against Varroa mites. The same heating mechanism serves multiple purposes across different types of brood combs, thereby maintaining ease of operation while significantly improving protection coverage for the entire bee colony.

AI summary
The invention relates to a device for combating the Varroa mite in a bee brood, comprising at least one foundation sheet (15, 16) which can be inserted, in particular, into a beehive (1, 2) and which is provided with brood cells (17) for female bees, wherein the device has an electric heating device comprising a resistance heating element (19) embedded in the foundation sheet (15, 16) and an associated control device (27, 28, 31) which is designed such that an automatically running heating process with a time-predetermined heating phase until a temperature of 39°C to 45°C, preferably 39°C to 42°C, is reached at the bottom of the brood cells (17) in the area of the resistance heating element (19) and then with a subsequent holding phase at this temperature for a predetermined time can be initiated.
