Coffee Grinder Burr Assembly for Easy Cleaning and Reassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee grinders are difficult to disassemble and reassemble, leading to residual coffee powder accumulation, which causes undesirable taste and odor issues and potential health risks from aflatoxin formation.
Innovation Solution
A coffee grinder design featuring a base with first and second assembly parts, allowing easy disassembly and reassembly through magnetic connections and elastic components, facilitating cleaning and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the coffee grinder uses a conventional integrated structure, then the device is compact and simple to manufacture, but it is difficult to disassemble and reassemble for cleaning and maintenance
Solution Approach 1:
The coffee grinder is divided into multiple separable components: a body, a first assembly part (containing the drive shaft), and a second assembly part (containing the inner and outer burr modules). These segmented parts can be easily disassembled and reassembled through magnetic connections and elastic components, enabling convenient cleaning and maintenance while maintaining a relatively simple overall structure.
2Reliability
If the grinding component is difficult to disassemble, then the structural integrity is maintained, but residual coffee powder accumulates causing health risks and undesirable taste
Solution Approach 1:
The grinding component is segmented into separable parts (inner burr module, outer burr module, drive shaft assembly) that can be easily disassembled for thorough cleaning. This segmentation allows users to access and clean all surfaces where coffee powder may accumulate, preventing aflatoxin formation and contamination while maintaining structural integrity through magnetic and elastic connections.
Solution Approach 2:
The coffee grinder incorporates magnetic connections and elastic components that enable users to easily disassemble and reassemble the grinding component without specialized tools or skills. This self-service design empowers users to perform routine cleaning and maintenance themselves, preventing harmful residue accumulation and ensuring ongoing safety and quality.
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 cleaning and maintenance by allowing easy disassembly and reassembly of the grinding component, reducing residual coffee powder accumulation and minimizing health risks.
Implementation Method 1
the elastic component is assembled between the drive rod and the fixing sleeve. One end of the elastic component is pressed against the drive rod. The other end of the elastic component is pressed against the fixing sleeve.
Implementation Method 2
The outer fixing member is connected to the inner fixing member.

AI summary
A coffee grinder including a base and a grinding component is provided. The base includes a body part, a first assembly part, and a second assembly part. The first assembly part and the second assembly part are connected to the body part and protrude from one side of the body part. The first assembly part is disposed above the second assembly part and includes a drive shaft. One end of the drive shaft faces the second assembly part. The grinding component includes an outer burr module and an inner burr shaft assembled in the outer burr module. A side surface of the outer burr module is assembled to the second assembly part. The drive shaft of the first assembly part is assembled with one end of the inner burr shaft. One end of the drive shaft drives the inner burr shaft to rotate relative to the outer burr module.
