Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee bean grinders are difficult to disassemble and reassemble for cleaning and maintenance, leading to residual coffee powder accumulation, which can cause undesirable taste and odor issues and potentially lethal aflatoxin formation in brewed coffee.
Innovation Solution
A coffee bean grinder design featuring a housing assembly, shaft component, and securing member, allowing for easy assembly and disassembly through a structural configuration that includes a shaft cap, elastic member, and securing groove, facilitating the removal of residual coffee powder for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the grinder structure is made compact and integrated, then the device size is reduced and aesthetics are improved, but the ease of disassembly for cleaning is worsened
Solution Approach 1:
The grinder is divided into distinct modular components including a removable shaft assembly, housing, and grinding chamber. The shaft component can be detached from the housing to access the grinding area for thorough cleaning, resolving the contradiction by enabling disassembly while maintaining a compact overall form factor when assembled.
Solution Approach 2:
The shaft component with inner grinding member is nested within the housing assembly, allowing the compact integrated appearance when assembled while enabling easy removal of the shaft for cleaning. The nested structure permits disassembly without increasing the device's overall volume.
2Stability of the object's composition
If the grinding components are securely fixed, then grinding stability and precision are improved, but the ease of disassembly for maintenance is worsened
Solution Approach 1:
The shaft component features a dynamic securing mechanism that can be easily engaged and disengaged. During operation, the shaft is securely fixed to maintain grinding stability, but during maintenance, the shaft can be quickly removed by actuating the securing mechanism, thus achieving both stable grinding and easy maintenance.
Solution Approach 2:
The securing mechanism is designed as a separate controllable component that independently manages the connection between shaft and housing. This segmentation allows the grinding components to be securely fixed during operation while enabling easy disassembly for maintenance without compromising either requirement.
3Loss of time
If residual coffee powder is not completely removed, then cleaning time is reduced, but the risk of aflatoxin formation and health problems increases
Solution Approach 1:
The segmented modular design with removable shaft assembly allows complete access to all grinding surfaces and crevices. This enables thorough removal of residual coffee powder from all areas, eliminating the source of aflatoxin formation while maintaining efficient cleaning through the simple disassembly process.
Solution Approach 2:
The shaft component containing the inner grinding member can be completely extracted from the housing, allowing direct access to and removal of all residual coffee powder from the grinding chamber and shaft surfaces. This extraction enables complete cleaning to prevent aflatoxin formation without requiring excessive time.

AI summary
A coffee bean grinder is provided, comprising a housing assembly, a shaft component, and a securing member. The shaft component is assembled in the housing assembly. When a coffee bean grinding complex is formed by an inner grinding member of the shaft component and an outer grinding member of the housing assembly, the shaft component and the housing assembly can be easily assembled and secured through the structural configuration of the securing member, and also through which, the shaft component and the housing assembly can also be disassembled for cleaning and maintenance after grinding operation.
