Cutting Disc with Removable Insert for Multi-Function Food Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting discs for household food preparation appliances are complex, costly, and prone to damage due to intricate mechanisms and multiple rotating axes, leading to high production costs and difficulties in cleaning and user error.
Innovation Solution
A cutting disc with a fixed blade and a removable insert featuring radial guide means for easy assembly and disassembly, allowing the insert to present two working faces and be driven by a motor shaft, preventing incorrect positioning and reducing complexity and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotatable tool with multiple axes is used to achieve multiple cutting functions, then the cutting disc can perform different cutting operations, but the device complexity increases significantly
Solution Approach 1:
The cutting tool is segmented into a fixed cutting blade attached to the disc and a removable insert with positioning means. The insert can be positioned in different locations on the disc perimeter, allowing different cutting functions without requiring a complex rotatable multi-axis tool mechanism.
Solution Approach 2:
A single removable insert serves multiple functions by being positionable at different locations on the disc. The same insert can perform different cutting operations depending on its position, eliminating the need for multiple specialized tools or a complex rotatable mechanism.
2Adaptability or versatility
If multiple separate inserts are used for different cutting functions, then each insert can be optimized for its specific function, but the quantity of components and storage requirements increase
Solution Approach 1:
A single removable insert is designed to perform multiple cutting functions by being positionable at different locations on the disc perimeter. This universal insert replaces what would otherwise require multiple separate specialized inserts, reducing component quantity and storage needs.
Solution Approach 2:
Multiple cutting functions are merged into a single insert component. By combining the functionality of what would be separate inserts into one multi-positionable insert, the system reduces the total number of components while maintaining functional versatility.
3Manufacturing precision
If a complex positioning mechanism with multiple rotation axes is used, then the insert can be precisely positioned, but the manufacturing cost increases
Solution Approach 1:
The positioning system is segmented into simple定位 means on the disc and corresponding positioning features on the insert. This segmented approach uses simple locators and positioning elements rather than complex multi-axis rotation mechanisms, reducing manufacturing cost while achieving precise positioning.
Solution Approach 2:
The positioning mechanism uses simple, inexpensive components such as locators and positioning features that can be easily manufactured. Rather than investing in complex precision mechanisms, the system uses simple, cost-effective positioning elements that achieve the required precision at lower manufacturing cost.
4Ease of operation
If the insert can be easily removed and repositioned, then cleaning and reconfiguration become simpler, but the risk of incorrect positioning increases
Solution Approach 1:
Positioning means are pre-configured on both the disc and the insert to guide correct positioning.的定位 features such as locators and positioning grooves are designed in advance to automatically guide the insert into the correct position, preventing incorrect positioning even though the insert is easily removable for cleaning and reconfiguration.
