Food Cutting Accessory Drive Coupling for Safe High-Power Slicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food cutting accessories are limited in cutting large quantities of food and lack sufficient power to cut hard foods, with a design that is not adaptable to different motorized boxes and poses safety risks due to complex construction.
Innovation Solution
A food cutting accessory with a platen and lid design that includes a primary cutting tool with a drive hub and sleeve system, a secondary cutting tool, and a conduit for discharging cut food, allowing for efficient cutting of large quantities and hard foods, while ensuring safety through a compact and adaptable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a bowl is used to receive cut food, then food can be contained, but the cutting capacity is limited and cannot handle large quantities of food
Solution Approach 1:
The invention removes the bowl component from the food cutting accessory design. Instead of containing cut food in a bowl, the system allows food to be cut and discharged directly into external containers placed on the working surface, thereby eliminating the volume limitation of the bowl while maintaining food containment through external means
Solution Approach 2:
The invention transitions from a three-dimensional enclosed bowl structure to a two-dimensional working surface approach. The platen provides a flat working surface where cut food can be dispersed and collected in external containers arranged around the cutting area, effectively increasing capacity by utilizing external space rather than internal containment
2Power
If a removable motor unit designed for hand-held use is used, then the device is portable, but it lacks sufficient power to cut hard foods such as carrots
Solution Approach 1:
The invention designs the platen with a universal mounting interface that can accommodate different motorized boxes. The drive means includes a drive head and drive sleeve system that can interface with various motor units, allowing the same cutting accessory to be used with multiple types of motorized boxes, thereby achieving both high power and adaptability
Solution Approach 2:
The invention employs a dynamic drive connection system where the drive sleeve can engage and disengage from the drive head. This allows the accessory to be easily mounted on and removed from different motorized boxes, providing adaptability while maintaining the capability to harness high power when connected to suitable motor units
3Reliability
If a locking element is used to prevent disassembly of the cover, then safety is improved, but the construction becomes sophisticated and less adaptable to different motorized boxes
Solution Approach 1:
The invention introduces a pusher as an intermediary component between the user and the cutting tool. The pusher applies downward force on the food to keep it pressed against the cutting surface during operation, providing safety by preventing direct hand contact with the rotating cutting tool while avoiding the need for complex locking mechanisms on the cover
