Herb Grinder Transfer Tool With Scraper and Pinch Ends
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no device available to clean the screen that sifts finer Keif particles in herb grinders, and existing methods of transferring herb material contaminate the material and hands with organic matter.
Innovation Solution
A multi-tool apparatus with a tubular body formed from a semi-rigid flexible material, featuring a scraper end and a pinching end, designed to scrape and collect herb material from the grinder, allowing for contamination-free transfer to an end use location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a herb grinder with a screen is used to separate Keif particles, then the separation of active ingredients is improved, but there is no device available to clean the screen
Solution Approach 1:
The patent combines the scraping function and the collection function into a single integrated tool. The tubular body with scraper edge can both scrape the screen to clean it and collect the scraped material in its hollow interior, eliminating the need for separate cleaning and collection devices.
Solution Approach 2:
The tool serves multiple functions: it acts as a screen cleaner, a collection container, and a transfer device. The same tubular body with scraper edge is used for both cleaning the screen and collecting/transferring the material, making it a universal tool for the entire process.
2Ease of operation
If fingers are used to transfer herb material, then the transfer is simple, but the organic matter is contaminated with contaminants from hands
Solution Approach 1:
The tubular body acts as an intermediary device between the screen and the user's hand. The material is transferred from the screen into the tubular body, which then allows transfer to the end use location without direct hand contact, preventing contamination while maintaining ease of operation.
Solution Approach 2:
The tool is designed to be self-contained, with the material held within the tubular body's hollow interior. The user simply inserts the tool, the material is already contained and ready for transfer, eliminating the need for manual handling and self-service the contamination prevention function.
3Ease of operation
If the tubular body is made of semi-rigid flexible material, then the side walls can be squeezed together for pinching action, but the structure becomes more complex
Solution Approach 1:
The patent changes the physical parameter of the material from rigid to semi-rigid flexible. This allows the material to be squeezed and pinched by hand while maintaining structural integrity when not being manipulated. The material properties are optimized to provide both flexibility for operation and stability for containment.

AI summary
A transfer device for material such as cannabis is provided for use with a grinding device and includes a flexible sheet material formed or molded around a hollow interior to define a generally tubular body which has a base wall and two side walls standing upwardly from the base wall. One end of the generally tubular body forms a scraper edge where the sides are recessed to form a shovel area over the base. The other end of the body forms a pinch end where the side walls converge to an upper slot which can be squeezed together to close the slot in a pinching action so as to pinch the material within the hollow interior between the side walls for manual transfer. The body is narrower at the second end so that material scraped into the body is converged by the side walls in the form of a funnel.
