Solution Overview

Problem

Existing food processing devices, such as combination peelers and slicers, face limitations in handling large or heavy food items due to the eccentricity of the advancing screw, requiring lengthy time for core retrieval and item repositioning, and often result in inefficient processing.

Innovation Solution

A food processing device with a gear housing, frame arm, and drive screw, coupled with a retention hub and input hub, enables synchronized rotational and linear movement, allowing for efficient peeling, slicing, and coring through a carrier with integrated cutting implements, and can be integrated with a stand-based mixer for enhanced power and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a conventional unanchored drive screw is used to advance the food item, then the device structure is simpler, but the screw sags under heavyweight causing eccentricity and limiting the size and weight of processable items

Engineering Contradiction:
Improvesupport capability for heavy food itemsVSAvoidstructure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The drive mechanism is segmented into a two-component system: a stationary gear housing that anchors the drive screw to prevent sagging, and a movable carrier that travels along the frame arm. This segmentation allows the heavy-duty anchored screw structure to support large food items while the separate carrier handles the processing functions, distributing the mechanical load effectively.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carrier acts as an intermediary between the anchored drive screw and the cutting implements. It translates the rotational movement of the screw into linear movement of the cutting tools, allowing the heavy-duty screw structure to indirectly drive the processing functions without the screw itself needing to directly hold or move the cutting elements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the food item is advanced through a conventional device, then processing can be performed, but lengthy time is required for retracting the core from the corer and advancing a new food item

Engineering Contradiction:
Improveprocessing speedVSAvoidtime for core retrieval and repositioning
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

Instead of advancing the food item through a stationary cutting mechanism, the invention inverts the approach by keeping the food item stationary on the anchored retention device and advancing the carrier with cutting implements through the food item. This inversion eliminates the need to retract and reposition heavy food items, significantly reducing cycle time.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The carrier automatically returns to its starting position after completing a cutting cycle, ready to immediately process the next food item. The anchored retention device continuously holds food items in place, eliminating downtime between processing cycles and enabling continuous operation.

Inventive Principle:
Principle #25Self-service

3Volume of moving object

If the drive screw is eccentric due to sagging, then the device can be simpler, but the size and weight of items to be processed are limited

Engineering Contradiction:
Improvesize of processable food itemsVSAvoiddrive mechanism complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The system separates the support function (anchored gear housing and retention device) from the processing function (movable carrier with cutting implements). This segmentation allows the anchored structure to provide stable, eccentricity-free support for large, heavy food items while the lighter carrier handles the dynamic processing operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carrier moves along the longitudinal axis of the frame arm, adding a linear movement dimension to the rotational movement of the drive screw. This dimensional change allows the processing tools to traverse the length of large food items without requiring the entire drive mechanism to move, enabling processing of oversized items.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Productivity

If conventional processing devices are used, then basic peeling and slicing can be performed, but synchronized rotational and linear movement for efficient processing is not achieved

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidmechanism synchronization complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention replaces complex multi-axis mechanical synchronization systems with a simpler screw-mechanism-based system. The threaded engagement between the drive screw and carrier automatically converts rotational movement into linear movement with precise, inherent synchronization, eliminating the need for separate motors, belts, or gears to coordinate multiple movements.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
