Modular Grinder Design for Detachable Cleaning and Oxidation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grinders, both manual and electric, face issues with powder adherence and odor generation due to the integrated electric driving device, making comprehensive cleaning difficult and leading to hygiene concerns.
Innovation Solution
A grinder design where the electric driving device is detachably positioned on one side of the receiving container, allowing for easy removal and comprehensive water cleaning of components like the grinding seat, grinding disk, and base, with a modular electric driving device and adjustable grinding mechanism to prevent over-oxidation and facilitate cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electric driving device is integrated into the machine body with the grinding disk and grinding seat fastened on it, then the grinding structure is stable and compact, but the components become difficult to detach for comprehensive cleaning
Solution Approach 1:
The grinder is divided into separate modules: the electric driving device is detached from the machine body, the grinding seat is separated from the base, and the grinding disk can be removed from the grinding seat. This segmentation allows each component to be independently cleaned without disassembling the entire device, resolving the contradiction between integrated stability and cleaning accessibility.
2Productivity
If the grinding disk, grinding seat and pulling sheet are fastened on the output shaft of the electric driving device, then the grinding operation is efficient, but complete cleaning of all areas including gaps becomes difficult
Solution Approach 1:
The grinding disk is extracted from the grinding seat, and the pulling sheet is removed from the grinding disk. This allows users to access and clean previously unreachable areas such as the gap between the grinding disk and grinding seat, as well as the underside of the pulling sheet, ensuring complete cleaning while maintaining grinding efficiency when reassembled.
3Speed
If high rotation speed (1,000 RPM) is used in electric grinder, then grinding speed is fast and coffee can be brewed immediately, but heat generated causes over-oxidation and loss of aroma
Solution Approach 1:
The grinder allows dynamic adjustment of rotation speed to match different grinding needs. Users can select high speed for quick grinding when time is critical, or low speed for aromatic coffee preparation where preserving volatile compounds is important. This dynamic control resolves the contradiction between grinding speed and oxidation prevention by allowing optimal speed selection for each specific task.
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 effective cleaning of all components, preventing powder adherence and odor generation, thus ensuring hygiene and health standards are met, and provides a more practical and efficient grinding process compared to conventional grinders.
Implementation Method 1
an electric driving device, detachably disposed in the installation space and including a power switch coupled to a power input socket and a motor
Implementation Method 2
a deceleration mechanism is driven by the motor
Implementation Method 3
a passive rod is sleeved with a conical grinding disk linked with the passive rod, the top end and the bottom end of the passive rod are respectively sleeved with the output shaft and the pivotal shaft, thereby allowing the grinding disk to protrude into the grinding seat
Implementation Method 4
the coffee beans are ground in almost 1,000 RPM (high rotation speed), so during the grinding process, heat generated by a grinding disk and a grinding seat served as a grinding device would be transferred to the coffee beans, so that the ground powders will be overly oxidized because of the raised temperature
