Foodstuff-grinding attachment for a kitchen machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foodstuff grinding attachments face difficulties in cleaning, particularly the cavity within the main body, due to operational forces and pressures, which complicates maintenance without compromising performance.
Innovation Solution
The attachment is designed with a split main body that allows for easy disassembly and cleaning, featuring a sliding or hinged configuration with tongue and groove mechanisms and flexible seals to secure and seal the parts, ensuring accessibility and resistance to operational forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the main body is made as a single strong component to resist operational forces, then the strength and reliability are improved, but the ease of cleaning deteriorates
Solution Approach 1:
The main body is divided into two separable components: a stationary component and a removable component. This segmentation allows the removable component to be detached for easy cleaning of the cavity while the stationary component remains to maintain structural strength during operation. The split design enables access to previously hard-to-reach areas without compromising the overall strength of the attachment.
2Ease of operation
If the main body is split into separable components to facilitate cleaning, then the ease of cleaning is improved, but the ability to resist operational forces deteriorates
Solution Approach 1:
The connection between the stationary and removable components uses a dynamic fastening system with a fastening element that can be easily engaged and disengaged. During operation, the components are securely fastened together to withstand high forces and pressures. During cleaning, the fastening element can be quickly released to separate the components. This dynamic approach allows the same structure to provide both strength during operation and ease of cleaning during maintenance.
3Ease of operation
If tool-free disassembly is implemented for cleaning, then the ease of operation is improved, but the reliability of securing components together deteriorates
Solution Approach 1:
The fastening element is designed to be manually operable without requiring external tools. The user can directly engage and disengage the fastening element through simple hand operations. This self-service mechanism maintains reliability during operation through secure mechanical engagement while providing tool-free disassembly for cleaning. The design eliminates the need for wrenches, screwdrivers, or other tools, making maintenance accessible to all users.
