Portable Herb Grinder With Manual-Electric Operation for Low-Effort Grinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable herb grinders are difficult for users with arthritis to operate and lack portability, as they often require significant force and are not suitable for grinding fresh herbs or tobacco in locations without electrical access, and they can be bulky and heavy.
Innovation Solution
A portable herb grinder with a rechargeable motor and manual operation capability, featuring a top section with rotating grinding knives, a middle section with upward-facing grinding knives and apertures, and a bottom section for collecting ground material, along with an optional storage section for transporting and storing herbs, allowing for both manual and powered grinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional portable herb grinders are designed with manual operation only, then the device remains simple and portable, but it requires significant force that is difficult for users with arthritis to operate
Solution Approach 1:
The grinder is designed to perform multiple functions: it can operate both manually by rotating the top cap and electrically via a rechargeable motor. This multi-functionality allows users with arthritis to benefit from the electric mode requiring minimal effort, while still maintaining the option for manual operation, thus resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
A rechargeable motor is introduced as an intermediary element that assists the manual grinding operation. The motor can be engaged to provide powered grinding when needed, reducing the physical effort required, while the overall device structure remains relatively simple and portable
2Productivity
If electrically powered grinders are used, then grinding efficiency is improved, but the device becomes bulky and heavy, reducing portability
Solution Approach 1:
The patent employs a rechargeable battery system with a motor that provides powered grinding capability. By using a compact rechargeable battery and efficient motor design, the device achieves improved grinding efficiency without becoming excessively bulky or heavy, thus maintaining portability while enhancing productivity
3Adaptability or versatility
If conventional grinders are designed for stationary use, then grinding performance is adequate, but the device lacks portability for use in locations without electrical access
Solution Approach 1:
The grinder incorporates both manual and electric operation modes, making it adaptable to various environments. Users can operate it manually in locations without electrical access, or use the electric motor when power is available, thus achieving location flexibility without excessive device complexity
Solution Approach 2:
The device transitions from a static, single-mode design to a dynamic, multi-mode system. The grinder can switch between manual and electric operation, and includes removable sections for easy cleaning and maintenance, enhancing its adaptability to different usage scenarios and locations
4Ease of operation
If grinding is done in advance and stored, then convenience is improved, but freshness of the ground material is compromised
Solution Approach 1:
The grinder includes storage compartments where ground material can be kept fresh until needed. Users can grind material in advance and store it in the integrated storage sections, maintaining freshness through proper storage, while having the convenience of pre-ground material readily available for future use
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
Enables efficient grinding of herbs and tobacco anywhere, with reduced user effort and increased portability, ensuring freshness and convenience for users with physical limitations and those needing to grind materials in non-electric environments.
Implementation Method 1
The portable herb grinder may further comprise a rechargeable battery system in electrical communication with the motor
Implementation Method 2
The top section further comprises a motor housed between a top motor mount and a bottom motor mount
Implementation Method 3
A dried herb or leaf is placed inside the first chamber. The top cap is then rotated relative to the rest of the grinder allowing the grinding knives to cut the herb into smaller pieces

AI summary
A portable grinder for herb or vegetative material comprises a top section having a motor and disc with a plurality of top grinding knives protruding downward, a middle section having a plurality of bottom grinding knives protruding upward and a plurality of apertures, and a bottom section. In one embodiment, ground material is discharged through apertures in the middle section, where the size is regulated by a screen, and/or is retained in the middle section until the top section is removed. In a further embodiment, the grinder may be operated electrically or manually.
