Electronic grinder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary shaft grinders have fixed blades, limiting users to a single mode of pulverization and failing to accommodate the varying dryness, hardness, and viscosity of different herbs, which restricts versatility in grinding and pulverizing.
Innovation Solution
A magnetic shaft connector system allows for easy removal and replacement of blade groups, enabling users to select blades based on the characteristics of the material to be ground, with a drive shaft connected to a motor and microcontroller for controlled operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the blade is fixedly connected to the shaft, then the structure is simple and reliable, but the blade cannot be easily replaced, limiting the user to a single mode of pulverization
Solution Approach 1:
The blade assembly is segmented from the drive shaft through a magnetic connector system. The blade group can be independently removed and replaced by detaching the magnetic shaft connector, allowing different blade configurations for different materials while maintaining a relatively simple overall structure.
Solution Approach 2:
A magnetic shaft connector acts as an intermediary between the drive shaft and the blade group. This magnetic intermediary enables easy attachment and detachment without complex mechanical fasteners, resolving the contradiction between ease of replacement and structural simplicity.
2Adaptability or versatility
If a single blade configuration is used, then the device structure is simple, but it cannot accommodate the varying dryness, hardness, and viscosity of different herbs
Solution Approach 1:
The grinder is designed with universal adaptability through interchangeable blade groups. Different blade configurations (e.g., different shapes, sizes, or arrangements) can be attached to the same magnetic shaft connector, allowing the device to handle various materials with different dryness, hardness, and viscosity characteristics without requiring multiple complete grinder units.

AI summary
A electronic grinder includes a base and a cup, the cup defining a pulverization chamber. A drive shaft connected to an electric motor terminates inside the pulverization chamber at a blade group. The blade group is magnetically removable from the end of the drive shaft for easy cleaning and replacement. The end of the cup opposite from the base in includes a fixed ring and a moveable cap that rotates or swivels about a pin connecting the two components for easy access to the contents of the pulverization chamber. The electric motor is controlled by a microcontroller operable by a power button and a control button. An inductive switch configured as a triggering member is disposed between the base and cup to detect whether the two components are connected in order to prevent inadvertent use of the grinder.
