Detachable Double-Layer Stirring Blade for Multi-Directional Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stirring blades for food processors, including single-layer and double-layer designs, are inefficient in cutting large pieces of food and often leave uncut portions due to limited cutting directions and uneven cutting efficiency.
Innovation Solution
A double-layer stirring blade design featuring two four-edged blades with a detachable connecting structure, allowing for adjustable angles and independent operation of each layer, providing additional cutting lines and improved food processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer stirring blade is used, then the structure is simple, but the cutting efficiency is low and large pieces of food cannot be cut
Solution Approach 1:
The stirring blade is divided into multiple layers (upper and lower blade assemblies) with each layer containing multiple blades. This segmentation allows food to be cut from multiple directions simultaneously, dramatically improving cutting efficiency while maintaining reasonable structural complexity through modular design
Solution Approach 2:
The invention transitions from a single-layer (2D) blade structure to a multi-layer (3D) structure with blades arranged at different heights and angles. This dimensional change enables cutting from multiple directions, allowing the blade to handle large pieces of food effectively without excessive structural complexity
2Productivity
If a double-layer stirring blade with fixed structure is used, then the stirring effect is improved, but large pieces of food between layers cannot be reached and cutting is uneven
Solution Approach 1:
The blade assemblies are designed to be movable relative to each other along the central axis, allowing dynamic adjustment of the spacing between upper and lower layers. This enables the structure to adapt to different food sizes and types, ensuring large pieces can be reached and cut evenly while maintaining good stirring effect
Solution Approach 2:
The detachable connecting structure allows the blade assemblies to be configured in different arrangements and spacing, making the stirring blade versatile for handling various food types and sizes. The same structure can be used for both stirring and cutting operations with different configurations
3Ease of operation
If a detachable connecting structure is used, then the structure is more complex, but assembly and disassembly become convenient
Solution Approach 1:
The stirring blade is segmented into detachable blade assemblies that can be easily assembled and disassembled. The connecting structure uses simple positioning pins and grooves with elastic elements, dividing the complex assembly into manageable components that are easy to handle and assemble
Solution Approach 2:
The positioning pin with elastic element acts as an intermediary component that simplifies the connection between blade assemblies. This mediator provides automatic positioning and securing through the elastic element, making assembly convenient without requiring complex fastening mechanisms

AI summary
A stirring blade includes an upper blade assembly and a lower blade assembly. The upper blade assembly includes a first four-edged blade and an upper blade carrier to which the first four-edged blade is fixed, and the lower blade assembly includes a second four-edged blade and a lower blade carrier to which the second four-edged blade is fixed. The upper blade carrier is connected to the lower blade carrier by a detachable connecting structure.
