Rotary Food Cutter Tool Retention With Integrated Hook and Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household food cutting appliances with rotary tools are complex in construction and difficult to use, as they require additional parts to retain the rotary working tool in place, which can be insufficient when food exerts force on the tool during cutting.
Innovation Solution
A household food cutting appliance with a motorized base and an integral working accessory featuring a drive member inclined downwards, which includes a hook and a retaining abutment, allowing the rotary working tool to be retained without additional parts, facilitating easy installation, removal, and cleaning, and enhancing food ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional parts are used to retain the rotary working tool in place, then the tool can be held securely, but the construction becomes more complex and difficult to use
Solution Approach 1:
The retaining abutment is integrated directly into the housing structure rather than being a separate component. The abutment is formed as an integral part of the housing wall, combining the housing and retention functions into a single structural element, thereby simplifying construction while maintaining tool retention security.
Solution Approach 2:
The retention function is extracted from the complex assembly of multiple retaining parts and embodied in a single, simple abutment structure. This isolated retention element is sufficient to hold the tool securely without requiring additional components, reducing overall device complexity.
2Reliability
If additional retaining parts are used, then the tool can be retained, but the ease of operation deteriorates due to more complex installation and removal
Solution Approach 1:
The retention mechanism is simplified to a single abutment structure that allows the tool to be installed by simply placing it against the abutment and removed by lifting it away. This eliminates complex installation procedures while maintaining secure retention during operation.
3Reliability
If additional retaining components are added, then tool retention is improved, but cleaning becomes more difficult
Solution Approach 1:
The retaining abutment is merged with the housing structure, creating a smooth, continuous surface without separate retaining components. This integrated design eliminates crevices and complex geometries that would trap food particles, making the entire housing easier to clean while maintaining tool retention functionality.
4Productivity
If the axis of rotation is inclined downwards, then food ejection is facilitated, but the tool requires additional retention mechanisms
Solution Approach 1:
The retention abutment is integrated into the housing structure designed for the inclined axis configuration. This merged design provides both the inclined geometry for effective food ejection and the retention function through the built-in abutment, eliminating the need for separate retention mechanisms and reducing overall complexity.
