Solution Overview

Problem

Existing food cutting equipment lacks the ability to dynamically adjust cutting thickness during operation, limiting versatility and efficiency in producing slices of varying thicknesses.

Innovation Solution

A cutting head with rotatable cutting tools and an adjustment mechanism, including a biasing element and moveable stops, allows for the adjustment of cutting thickness by rotating the cutting tools between different positions, enabling the production of slices of varying thicknesses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cutting tool position is fixed, then the cutting thickness remains constant, but the versatility to produce varying slice thicknesses is limited

Engineering Contradiction:
Improveability to produce slices of varying thicknessesVSAvoidcomplexity of adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cutting tool is made rotatable between multiple discrete positions (first position, second position, and intermediate positions) to dynamically adjust the cutting gap. This allows the cutting thickness to be varied during operation by rotating the cutting tool to different angular positions, transforming a static cutting system into a dynamic one that can adapt to different thickness requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustment mechanism is segmented into discrete positional stops (first stop, second stop, and intermediate stops) that correspond to specific cutting thicknesses. Rather than requiring continuous adjustment, the system divides the adjustment range into distinct segments, each providing a predetermined cutting thickness, thereby simplifying the adjustment mechanism while maintaining versatility

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the cutting tool is made adjustable to change thickness, then versatility improves, but the device complexity increases due to additional adjustment mechanisms

Engineering Contradiction:
Improveadjustability of cutting thicknessVSAvoidnumber of adjustment components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cutting tool incorporates self-indexing features with predetermined stops that automatically maintain accurate positioning during adjustment. The cutting tool itself participates in the adjustment process through its rotational movement and engagement with the stop mechanism, reducing the need for complex external adjustment devices and control systems

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system changes the cutting thickness parameter by rotating the cutting tool to different angular positions rather than by physically moving or replacing components. This parameter change approach allows versatility to be improved while keeping the mechanical structure relatively simple, as the same cutting tool can produce different thicknesses through positional changes

Inventive Principle:
Principle #35Parameter changes
