Bean grinding machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bean grinding machines face issues with mildew and bad odor due to residual bean powder that cannot be easily cleaned from the grinding mechanism, particularly because the lower grinding member is not detachable.
Innovation Solution
A bean grinding machine design where both the first and second grinding members are rotatable and removable from the base seat, allowing for easy cleaning and assembly, with a locking mechanism that ensures secure attachment during operation and facilitates disassembly for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the lower grinding member is fixed to the base seat for stable operation, then the structural stability is improved, but the ease of cleaning deteriorates due to inability to remove residual powder
Solution Approach 1:
The grinding mechanism is divided into separable components: the upper grinding member can be removed from the base seat, and the lower grinding member can be detached from the drive transmission. This segmentation allows each component to be independently cleaned, solving the cleaning difficulty while maintaining structural stability during operation through the drive transmission connection.
Solution Approach 2:
The lower grinding member is extracted from the fixed structure and made detachable from the drive transmission. This extraction enables complete removal of the grinding members for thorough cleaning, eliminating the accumulation of residual powder while the drive transmission provides stable operational connection when assembled.
2Ease of operation
If the upper grinding member is made removable for cleaning, then the ease of cleaning is improved, but the device complexity increases due to additional removal and installation mechanisms
Solution Approach 1:
The grinding mechanism is segmented into the upper grinding member, lower grinding member, and drive transmission as separate removable components. This segmentation enables cleaning without requiring complex disassembly mechanisms, as each component can be independently removed and reinstalled through simple interface connections.
3Ease of operation
If both grinding members are made detachable for easy cleaning, then the ease of cleaning is improved, but the reliability deteriorates due to potential loosening during operation
Solution Approach 1:
The grinding members are segmented as detachable components with defined interfaces to the drive transmission and base seat. These interfaces are designed to provide secure connection during operation while allowing easy removal for cleaning, balancing reliability and ease of maintenance.
Solution Approach 2:
The lower grinding member is extracted from the fixed structure and made detachable from the drive transmission. This extraction enables complete removal for cleaning while the drive transmission connection ensures reliable operation when assembled, preventing loosening through proper mechanical engagement.

AI summary
A bean grinding machine includes a base seat (1), a bean container (2) mounted on the base seat (1), and a grinding mechanism (3) removably mounted on the base seat (1). The grinding mechanism (3) includes first and second grinding members (32, 33) which are rotatable relative to and cooperate with each other to define a grinding space (30) for receiving beans introduced from the bean container (2). Both the first and second grinding members (32, 33) can be removed from the base seat (1) for facilitating cleaning.
