Solution Overview

Problem

Existing cutting and lifting operations require multiple utensils, typically a knife for cutting and a spatula for transferring, which is inefficient and cumbersome, especially in scenarios like cutting and serving food at events or in robotic manufacturing.

Innovation Solution

A single utensil, the cutting tong, integrates ergonomic handles with integrated sharp blades for cutting and grasping, featuring a spring system for opening and a lock mechanism for closure, allowing one-handed cutting and lifting of shaped pieces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple utensils (knife and spatula) are used for cutting and lifting, then cutting and transferring functions are performed, but device complexity and operation time increase

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines a cutting blade and a tong mechanism into a single integrated utensil. The blade is positioned at the end of the tong handle, allowing both cutting and grasping functions to be performed with one tool rather than requiring separate knife and spatula utensils.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The utensil performs multiple functions: cutting (via the sharp blade), grasping (via the tong mechanism), and lifting (via the handle). This multi-functional design eliminates the need for multiple specialized tools, reducing both device complexity and operation time.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple utensils are used for cutting and lifting, then cutting and transferring functions are performed, but loss of time increases

Engineering Contradiction:
ImproveproductivityVSAvoidloss of time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent combines a cutting blade and a tong mechanism into a single integrated utensil. The blade is positioned at the end of the tong handle, allowing both cutting and grasping functions to be performed with one tool rather than requiring separate knife and spatula utensils.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The continuous design allows the user to cut and immediately grasp the cut piece without putting down the first tool or picking up a second tool. This eliminates idle time between cutting and transferring actions, maintaining continuous productive motion.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If non-stick coating is applied to the blade, then items are released easily, but manufacturing complexity increases

Engineering Contradiction:
Improveease of operationVSAvoidease of manufacture
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent applies a non-stick coating to the blade surface, changing the surface properties of the metal. This coating reduces friction and prevents sticking, allowing cut pieces to be easily released from the blade onto the tong or serving surface.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The blade is constructed as a composite structure: a metal base providing strength and sharpness, combined with a non-stick coating layer providing release properties. This composite approach combines the advantages of both materials while mitigating their individual limitations.

Inventive Principle:
Principle #40Composite materials

AI summary

The present invention comprises a novel cutting device generally consisting of a tong-like shape, which is capable of slicing and then lifting a shaped piece from a larger whole. Different shapes may be used to perform substantially the same action, resulting in different shapes taken from the whole. The tongs have an angled (45 degrees) handle to provide comfort for the user's wrist and forearm.
