Solution Overview

Problem

Conventional cutting tools, such as hand kitchen knives and guided cutting devices, experience increased friction over time, leading to inefficient cutting and potential tearing or crushing of food due to dull edges and friction surfaces, which can result in suboptimal cutting performance.

Innovation Solution

A kitchen slicer with a blade that is supplied with a fluid, reducing friction between the blade and the material being cut, allowing for smoother cutting movements and preventing the blade from penetrating further into the material, while also providing a mechanism to distribute the fluid over the cut surface to prevent oxidation and enhance food handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional hand kitchen knives are used for cutting, then the cutting edge becomes dull over time, but the friction between the knife and food increases, leading to tearing or crushing of soft foods

Engineering Contradiction:
Improvecutting performanceVSAvoidfriction force
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A fluid is introduced as an intermediary substance between the blade and the food material. The fluid reduces friction during the cutting process, preventing the blade from slowing down as it penetrates the material and avoiding tearing or crushing of soft foods.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The friction characteristics of the blade surface are changed by applying a fluid. This modifies the physical parameters of the interface between blade and food, reducing friction and improving cutting performance throughout the blade's use life.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If a cutting knife is held in a frame with a friction surface to guide food, then the food is pressed against the cutting blade, but the pressure force increases friction effect between the knife and food

Engineering Contradiction:
Improvecutting precisionVSAvoidfriction effect
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The fluid acts as a mediator between the friction surface and the food, reducing the friction effect while maintaining the pressure force needed for precise cutting. This allows the guided cutting device to maintain precision without excessive friction.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the blade penetrates deeper into the material to be cut, then the cutting action continues, but the friction slows down the cutting movement

Engineering Contradiction:
Improvecutting speedVSAvoidfriction resistance
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The fluid intermediary reduces friction resistance throughout the cutting process, allowing the blade to penetrate deeper into the material without experiencing increased friction that would slow down the cutting movement.

Inventive Principle:
Principle #24Intermediary (Mediator)
