Solution Overview

Problem

Existing methods for producing honeycomb-patterned foundation sheets for beehives are complex, require multiple steps, and are not cost-effective for small beekeepers who lack sufficient wax quantities, often necessitating the use of externally sourced wax that may introduce diseases or pesticide residues.

Innovation Solution

A device with counter-rotating rollers featuring chambers and capillary-connected channels for separating and cooling agents, allowing for direct application of beeswax without additional processing steps, and enabling production through additive manufacturing for simplicity and cost-effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional multi-step production methods are used for foundation sheets, then the honeycomb pattern can be produced, but the production process becomes complex and requires multiple processing steps including casting, imprinting, trimming, and cutting

Engineering Contradiction:
Improvehoneycomb pattern qualityVSAvoidproduction process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple production steps (casting, imprinting, trimming, cutting) into a single integrated roller device. The roller simultaneously performs pattern imprinting and edge trimming in one operation, eliminating the need for separate processing steps and reducing overall production complexity while maintaining pattern quality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The roller is designed with multi-functional capabilities: it serves as both an imprinting tool for creating the honeycomb pattern and a trimming tool for cutting the foundation sheet edges. The hollow cylindrical structure with internal chambers allows it to also function as a cooling device, making a single component perform multiple tasks that previously required separate devices

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

2Quantity of substance

If small beekeepers use externally sourced wax for foundation sheet production, then sufficient material quantity is available, but the risk of introducing diseases, pests, or pesticide residues increases

Engineering Contradiction:
Improvewax quantityVSAvoidcontamination risk
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The invention enables small beekeepers to produce their own foundation sheets using their own collected wax, making the production process self-sufficient. The simplified single-step roller device allows them to process small quantities of wax without needing to source material externally, thereby eliminating contamination risks while maintaining adequate material supply for their needs

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If wax is used without cooling agents during production, then the production process is simple, but the wax deforms and adheres to the roller

Engineering Contradiction:
Improveproduction simplicityVSAvoidwax deformation
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent introduces cooling agents (such as water or alcohol) as intermediaries between the hot wax and the roller surface. These agents are supplied through channels in the hollow roller to the outer circumferential surface, where they cool the wax immediately upon contact, preventing deformation and adhesion while maintaining production simplicity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention replaces complex mechanical cooling systems with a simpler fluid-based cooling approach. Instead of using mechanical refrigeration or complex thermal management systems, the hollow roller delivers cooling agents directly to the wax through internal channels, achieving effective cooling with minimal mechanical complexity

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