Detachable Grinding Container Coupling to Eliminate Cleaning Downtime
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding devices require extensive cleaning between operations, especially when handling contaminated or toxic substances, leading to significant time loss due to the difficulty in accessing and cleaning the tool and container interface.
Innovation Solution
The device allows for the detachable coupling of the container and tool with the drive, enabling easy exchange and centering, eliminating the need for cleaning by allowing the container and tool to be replaced after a single use, with a coupling mechanism that includes a cylindrical and conical design for secure and quick attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container and tool are permanently connected to the drive, then the structure is simpler and more stable, but cleaning becomes extremely difficult and time-consuming
Solution Approach 1:
The device is divided into separable components: the container with tool can be detached from the drive unit. This segmentation allows the container to be easily removed for cleaning or replacement, while the drive unit remains stationary and reusable.
Solution Approach 2:
The coupling mechanism transitions from a static permanent connection to a dynamic detachable connection. The bayonet coupling allows quick attachment and detachment, enabling the system to switch between operational and cleaning states efficiently.
2Productivity
If the container and tool are cleaned thoroughly between operations, then contamination is reduced, but significant time is lost during cleaning
Solution Approach 1:
The container with tool can be designed as a disposable or single-use component. After one grinding operation, the entire container assembly can be discarded or set aside for cleaning, while the expensive drive unit remains in use. This eliminates the need to clean the drive and its internal components.
Solution Approach 2:
The container with tool is extracted as a separate removable unit from the drive. This extraction allows the container to be cleaned, disposed of, or stored independently, while the drive continues operating without interruption for cleaning purposes.
3Manufacturing precision
If the tool is firmly mounted in the container, then positioning precision is improved, but the tool cannot be easily replaced or cleaned
Solution Approach 1:
The tool mounting is segmented into two levels: the tool is firmly mounted in the container for precision, while the container itself is detachably mounted to the drive. This allows the tool to maintain precise positioning during operation while the entire container assembly can be easily removed for replacement or cleaning.
4Loss of time
If the container and tool are disposed of after single use, then cleaning time is eliminated, but the device complexity and initial cost increase
Solution Approach 1:
The container with tool is designed as an inexpensive disposable component that can be discarded after single use. The high-value drive unit is preserved and reused. The disposable nature of the container eliminates all cleaning requirements while the overall system remains simple because only the low-cost container is disposable.

AI summary
A device (1) for comminuting or grinding including a container (2) for receiving the material to be ground and a tool (5) which rotates in the container (2) during processing, and a drive for said tool (5). The container (2) having the tool (5) can be detachably coupled to the drive, which is to say that the container (2) having the tool (5) does not have to be cleaned after a grinding operation but can be replaced by a new such container (2). For this purpose, the tool (5) located in the container (2) can be rotated loosely when in the position of being detached or uncoupled from the drive or before a corresponding coupling operation and, when in the working position, is rotationally fixedly connected to the drive and centered by the coupling.
