Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple food articles are sliced simultaneously on high-speed slicing machines, then productivity is improved, but independence of feed rate control for each article deteriorates

Engineering Contradiction:
Improveslicing speedVSAvoidindependent feed rate control
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent divides the feeding system into separate independent conveyors for each food article position. Each conveyor can be controlled independently to accommodate different feed rates for different articles, resolving the contradiction between simultaneous slicing capability and independent control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs dynamic speed control of conveyor belts, allowing each conveyor to adjust its speed independently based on the specific requirements of each food article being sliced, enabling both high-speed operation and independent feed rate control.

Inventive Principle:
Principle #15Dynamics

2Productivity

If automated loading and continuous feed mechanisms are used, then productivity is improved, but hygiene issues worsen

Engineering Contradiction:
Improvecontinuous slicing capabilityVSAvoidcontamination risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the debris removal function into a separate automated conveyor system that continuously removes sliced portions and waste materials from the slicing area, maintaining hygiene while preserving continuous operation capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements self-cleaning features where the slicing blade and conveyor surfaces are designed to be easily cleaned or automatically cleaned, reducing contamination risk while maintaining automated continuous operation.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If gate mechanisms are used to control food article feeding, then slicing precision is improved, but complexity of the feeding mechanism worsens

Engineering Contradiction:
Improveslicing accuracyVSAvoidgate mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical gate mechanisms with simpler conveyor belt positioning systems that use friction and gravity to control food article feeding, maintaining slicing precision while reducing mechanical complexity.

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