Solution Overview

Problem

Existing food product cutting devices have complex structures that are difficult to install, costly, and hard to clean due to multiple parts and large movement areas, leading to contamination risks and increased machine size.

Innovation Solution

A device with a movable arm and tray system that moves in a plane parallel to itself, minimizing the movement zone and using actuating means to optimize scanning, with a compact design and easy cleaning features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a telescopic arm with carriages and rails is used to move the cutting head, then the cutting head can be positioned and moved in rectangular directions, but the structure becomes complex and difficult to clean

Engineering Contradiction:
Improvecutting head positioning capabilityVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent removes the complex telescopic arm, carriages, and rails system from the device. Instead, it uses a simple movable table that translates in a plane, extracting only the essential function of moving the cutting head while eliminating the complex mechanical structures that caused cleaning difficulties and high manufacturing costs.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Rather than moving the cutting head along fixed rails and carriages, the patent inverts the approach by moving the table underneath the cutting head. The cutting head remains relatively stationary while the table carries the product through the cutting zone, simplifying the overall structure.

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

2Area of stationary object

If multiple parts and large movement areas are used, then the cutting head can cover a large working area, but the device becomes hard to clean and contamination risk increases

Engineering Contradiction:
Improveworking area coverageVSAvoidcontamination risk
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent uses a dynamic table that translates in a plane with a minimized movement zone. The table moves only where necessary to cover the required working area, reducing the overall surface area that needs cleaning and minimizing areas where food particles could accumulate.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent optimizes the movement zone dimensions by controlling the ratio between the movement zone area and the plate area. This parameter optimization ensures adequate working area while minimizing the surface area subject to contamination and cleaning requirements.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If actuators are positioned on the sides of the travel area, then the plate can be moved in perpendicular directions, but the machine footprint increases

Engineering Contradiction:
Improveplate movement capabilityVSAvoidmachine footprint
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent combines the movement functions into a single integrated movable table system that translates in a plane. Instead of separate actuators on sides for X and Y movements, the table itself performs combined movements, reducing the machine footprint to approximately 2 x A x B.

Inventive Principle:
Principle #5Merging (Combining)

4Device complexity

If a fixed table is used, then the structure is simple, but the arm must make large amplitude movements increasing machine size

Engineering Contradiction:
Improvestructure simplicityVSAvoidmachine size
Core Design Contradiction:
Device complexityVSVolume of stationary object

Solution Approach 1:

The patent transforms the fixed table into a dynamic movable table that translates in a plane. This dynamic element allows the cutting head to access the entire working area without requiring large amplitude movements of the arm, as the table brings the product to the cutting position.

Inventive Principle:
Principle #15Dynamics
