Modular Lid Assembly for Food Processor Feed Tube Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processing devices lack modularity and ease of use, particularly in handling different food item sizes and processing operations, with a fixed-size feed tube that is not ideal for tasks like spiral cutting or blending small ingredients.
Innovation Solution
A modular lid assembly for a food processor that allows easy configuration based on the type and size of food items, featuring interchangeable covers and feed tubes, including a flat cover, large feed tube, and spiral feed tube, with a pusher assembly to adjust the feed tube opening size for optimal processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size feed tube is used in existing food processors, then the device structure is simple, but the device cannot adapt to different food item sizes and processing operations
Solution Approach 1:
The lid assembly is segmented into multiple interchangeable components including different feed tubes (large, medium, small sizes), covers, and pushers. Each component can be independently selected and attached to the lid based on the specific processing requirements, allowing the system to adapt to various food item sizes and operations without requiring a completely different lid assembly.
Solution Approach 2:
The modular lid assembly components are designed with universal attachment mechanisms that allow different feed tubes, covers, and pushers to be interchangeably mounted on the same lid. This multi-functionality enables a single lid base to serve multiple processing purposes by simply changing the attached components, thereby improving adaptability without proportionally increasing overall device complexity.
2Productivity
If a single fixed feed tube size is used, then the device is easy to operate, but the processing performance is limited for different food types
Solution Approach 1:
The feed tube assembly is designed with dynamic adjustability through interchangeable components. Users can quickly change feed tube sizes and pusher configurations depending on the food items being processed. This dynamic reconfiguration capability allows the system to optimize processing performance for different food types while maintaining ease of operation through simple attachment and detachment mechanisms.
Solution Approach 2:
The system allows changing of physical parameters such as feed tube diameter, opening size, and pusher position by swapping components. For example, larger feed tubes are used for whole fruits and vegetables, while smaller feed tubes are used for chopped ingredients. This parameter variability enables optimized processing performance for different food types without complicating the user interface or operation procedure.
3Adaptability or versatility
If interchangeable modular components are added to the lid, then the adaptability improves, but the number of parts and device complexity increases
Solution Approach 1:
Smaller feed tubes and pushers are designed to nest within or alongside larger components when not in use. This nesting arrangement allows multiple interchangeable parts to be stored compactly within the lid assembly or attached in a nested configuration, reducing the space required for storage and making it easier to manage the number of parts without sacrificing adaptability.

AI summary
A food processor includes a base, a motor disposed within the base, a drive shaft operatively connected to the motor and extending outwardly from the base, the output shaft being rotatable upon actuation of the motor, a bowl mounted on the base for containing food items, a modular lid for covering the bowl and having an opening therein, and a removable attachment receivable by said opening.
