Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processing devices face limitations in versatility and risk of malfunctions due to limited angle of pivotable knives and reliance on specific drive mechanisms, which restricts processing options and increases initial torque requirements for hard foodstuffs.
Innovation Solution
An operative insert with a freewheel mechanism that allows for torque-locking attachment to a drive interface, enabling reversible rotation and uncoupling of working means during reverse rotation, reducing the risk of damage and enhancing processing variability across different drive mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed drive mechanism is used to rotate the operative insert, then the device structure is simple, but the processing versatility is limited and the risk of damage from incorrect rotation is high
Solution Approach 1:
The patent applies the dynamics principle by introducing a freewheel mechanism that allows the operative insert to rotate freely in the working direction while automatically preventing rotation in the reverse direction. This dynamic uncoupling mechanism enables the same drive interface to be used with different drive mechanisms (crank drive, cord pull drive, toggle lever drive, humming top drive) without requiring additional freewheels, thus improving processing versatility while maintaining simple device structure.
2Adaptability or versatility
If pivotable knives with limited angle are used, then the initial torque requirement is reduced, but the processing options are restricted
Solution Approach 1:
The patent applies segmentation by dividing the cutting function into multiple independent working means (cutting knives, blending blades, peeling arms, stirring blades) that can be arranged in various configurations on the operative insert. This allows different processing options to be achieved with the same drive mechanism, improving versatility without increasing initial torque requirements, as each working means can be independently optimized for its specific function.
3Reliability
If the operative insert is directly connected to the drive interface, then torque transmission is reliable, but damage occurs during reverse rotation
Solution Approach 1:
The patent introduces a freewheel mechanism as an intermediary between the drive interface and the operative insert. This intermediary component allows reliable torque transmission during normal operation while automatically disengaging during reverse rotation, thus protecting the operative insert from damage without compromising torque transmission reliability. The freewheel acts as a one-way coupling that mediates between the drive force and the working means.
4Object-affected harmful factors
If additional freewheels are added to the drive mechanism, then protection from reverse rotation is improved, but the device complexity increases
Solution Approach 1:
The patent merges the freewheel function directly into the operative insert structure, combining the drive interface and freewheel mechanism into a single integrated component. This eliminates the need for additional separate freewheels in the drive mechanism, as the operative insert itself provides the reverse-rotation protection. The merging of functions reduces device complexity while maintaining protection from incorrect manipulation.
