Rotating Brush Mechanism for Gentle Flower Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for separating plant flowers from their stalks are labor-intensive, costly, and often result in a high percentage of stalks remaining with the flowers, with existing mechanized processes being inefficient and ineffective.
Innovation Solution
An apparatus featuring rotatable tubes with flexible elongated members that gently brush against the plants to separate flowers from stalks, using a motor-powered system and a platform to support and guide the plants during the separation process, with optional vacuum and conveyor systems for efficient flower collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hand separation is used, then separation quality is improved, but labor intensity increases
Solution Approach 1:
The patent replaces manual hand separation with a mechanical brushing system consisting of rotating tubes with flexible elongated members that gently brush against plant stalks to remove flowers, thereby maintaining separation quality while eliminating labor intensity
Solution Approach 2:
The flexible elongated members are designed with specific material properties (flexibility, softness) and dimensional parameters (length, diameter) that allow them to gently contact and brush flowers from stalks without damaging the flowers, replicating the gentle action of hand separation while providing mechanical automation
2Productivity
If cutting method is used, then separation speed is improved, but flower integrity deteriorates
Solution Approach 1:
The patent replaces the cutting mechanical action with a gentle brushing mechanical action, where rotating flexible members lightly contact and remove flowers from stalks without cutting or damaging the flower structure, thus maintaining both speed and integrity
Solution Approach 2:
The flexible elongated members are designed as flexible elements that can conform to the plant stalk surface and gently brush flowers away without applying excessive force that would damage the flower, enabling intact separation at mechanical speeds
3Productivity
If current mechanized processes are used, then productivity is improved, but separation quality deteriorates
Solution Approach 1:
The flexible elongated members are designed with specific local properties (flexibility, softness, specific dimensions) that enable gentle contact with flowers at the point of separation, allowing mechanized operation while maintaining high separation quality by adapting the mechanical action to the delicate nature of the flower-stalk interface
Solution Approach 2:
The patent uses flexible materials and specific dimensional parameters for the elongated members that allow the mechanical system to operate with gentle, controlled contact forces, achieving both high productivity through automation and high separation quality through material and design parameter optimization
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus provides a cost-effective and efficient method for separating flowers from stalks, reducing labor and improving separation quality by gently removing flowers without leaving significant stalk material behind, while also capturing valuable plant terpenes and essential oils.
Implementation Method 1
the elongated members gently brush against the plant and thereby remove flower from the stalk

AI summary
An apparatus and method for separating plant flowers from stalks by means of a lateral rotating tube having a plurality of flexible, elongated members affixed to and extending radially outward from the tube. The apparatus may include a platform and a frame supporting the tube above the platform to accommodate plants held between the platform and the tube so that when the tube is rotating, the elongated members affixed thereto brush against the plants and cause the flowers to brush off at and separate from the stalks. The frame further supports a housing to form a contained space, with a hood to direct the flow of flowers after separation from the stalks. The back wall is positioned a distance away from the platform to allow separated flower and stalk to be eliminated from the apparatus.
