Food Processor Drive Interlock Mechanism for Continuous Spiralising
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spiralising methods require manual reloading of ingredients and lack continuous processing capabilities, and existing kitchen machines suffer from usability issues and are often single-purpose devices.
Innovation Solution
A food processor accessory with a drive interlock mechanism and cutting tool that allows for continuous spiralising of ingredients by engaging with a rotating drive when a lid is fitted, featuring a gear engagement formation and spring-urged mechanism to ensure seamless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual reloading method is used, then device complexity is reduced, but productivity decreases due to intermittent processing
Solution Approach 1:
The system automatically detects lid presence and engages/disengages the drive mechanism without user intervention. The interlock mechanism self-activates when the lid is fitted, enabling continuous processing across multiple ingredients while maintaining safety, thus improving productivity without requiring complex manual control systems
Solution Approach 2:
The lid acts as an intermediary element that triggers the drive engagement. By using the lid's presence as a signal to activate the interlock mechanism, the system achieves automated continuous processing while keeping the control mechanism simple and reliable
2Adaptability or versatility
If dedicated single-purpose device is used, then manufacturing precision is improved, but adaptability decreases
Solution Approach 1:
The food processor is designed with a universal attachment system that accepts multiple cutting tools (spiralising blade, slicing blade, grating disc, etc.). The standardized engagement formation and drive interface allow a single base unit to perform multiple food preparation functions, enhancing versatility without requiring separate dedicated machines for each function
Solution Approach 2:
The system divides the food processor into modular components: a base unit with motor and drive mechanism, and interchangeable cutting attachments. This segmentation allows each component to be optimized independently while maintaining ease of manufacture through standardized interfaces and assembly procedures
3Reliability
If engagement formation is at axis of rotation, then cutting efficiency is improved, but safety decreases without interlock mechanism
Solution Approach 1:
The interlock mechanism is designed to prevent drive engagement before the lid is properly fitted. The cooperating member on the lid must be in place to allow the engagement formation to connect with the rotating drive, thereby preemptively preventing accidental activation and ensuring safety before operation begins
Solution Approach 2:
The system provides immediate feedback through the interlock mechanism: when the lid is fitted, the cooperating member enables drive engagement; when removed, the spring automatically disengages the drive. This real-time feedback ensures safety while maintaining operational convenience through automatic response to lid presence
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous and efficient spiralising of multiple ingredients without manual reloading, improving usability and versatility in kitchen machines.
Implementation Method 1
means for urging the engagement formation away from the rotating drive when the lid is not fitted to the attachment
Implementation Method 2
the lid comprises a complementary surface for cooperating with the cooperating member as to urge the engagement formation into engagement with the rotating drive when the lid is fitted to the food processor
Implementation Method 3
The engagement formation may be a gear and the means for urging may be a spring
