External Thickness Control for Adjustable Food Processor Slicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processors lack an efficient mechanism for adjusting the cutting thickness of food items, requiring users to manually change cutting tools or adjust components within the processing chamber, which is inconvenient and limits versatility.
Innovation Solution
A food processor with a motor-driven cutting assembly and an external control device, such as a screw-type drive assembly, allows users to adjust the distance between the cutting blade and rotating disk from outside the processing chamber, enabling easy variation of cutting thickness without removing the lid, using a control knob and shaft system to move the cutting blade or disk relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users manually change cutting tools or adjust components within the processing chamber to change cutting thickness, then cutting thickness can be adjusted, but user convenience deteriorates and operation complexity increases
Solution Approach 1:
The control mechanism is extracted from the processing chamber and placed on the exterior of the food processor housing. Users can adjust cutting thickness by operating controls on the outside of the chamber, eliminating the need to open the lid or reach inside to make adjustments. This maintains cutting thickness adaptability while dramatically improving ease of operation.
Solution Approach 2:
An intermediary control system is introduced between the user and the cutting assembly. The control mechanism includes a control member that transmits adjustment commands through the housing wall to the cutting assembly inside the chamber. This intermediary allows users to adjust cutting thickness without directly accessing internal components, resolving the contradiction between adaptability and ease of operation.
2Adaptability or versatility
If multiple interchangeable cutting tools are used to achieve different cutting thicknesses, then cutting versatility is improved, but device complexity and time to change tools increase
Solution Approach 1:
The cutting assembly is designed with dynamic adjustability, allowing the cutting blade position to be changed continuously along the feeding direction of the food item. Instead of requiring multiple static cutting tools, a single cutting tool can be dynamically repositioned to achieve different cutting thicknesses, reducing device complexity while maintaining versatility.
Solution Approach 2:
The cutting thickness is controlled by changing the positional parameter of the cutting blade relative to the food item feed path. By adjusting the blade position along the feeding direction, different cutting thicknesses are achieved without changing the cutting tool itself. This parameter-based adjustment reduces the number of tools needed while maintaining cutting versatility.
3Adaptability or versatility
If cutting blade position is fixed, then device simplicity is maintained, but cutting thickness adaptability is limited
Solution Approach 1:
The control mechanism is designed to be self-contained and self-operating. The control member on the exterior housing is directly coupled to the cutting assembly through the housing wall, creating a self-service system where the user's input directly adjusts the cutting blade position without requiring complex intermediate mechanisms or additional components.

AI summary
A food processor includes a bowl with a removable lid. Food items are advanced into the bowl through a feed tube formed in the lid where they are cut by a cutting assembly. The cutting assembly is adjustable to vary the thickness of the cut food items. A user-operated control device adjusts the cutting thickness of the cutting assembly. The control device is located outside of the bowl.
