Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If goggles are used to protect eyes from lachrymator particles, then eye protection is improved, but ease of operation and visibility deteriorate

Engineering Contradiction:

Improveeye irritation protectionVSAvoidvisibility and comfort

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent replaces the mechanical/physical barrier system (goggles) with an electromagnetic field-based system. The smartphone emits radio frequency electromagnetic waves that interact with lachrymator particles to neutralize or reduce their irritant effect, eliminating the need for physical eye protection equipment while maintaining ease of operation and clear visibility.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If specialized equipment is used to reduce lachrymator particles, then effectiveness is improved, but device complexity and cost increase

Engineering Contradiction:

Improvelachrymator particle reductionVSAvoidequipment requirements

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent leverages the universal multi-functionality of the smartphone, which already contains radio frequency transmission capabilities for communication purposes. The same hardware components (antenna, radio frequency circuit) are repurposed to emit electromagnetic waves targeted at neutralizing lachrymator particles, eliminating the need for specialized equipment while maintaining effectiveness.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If traditional methods like chilling onions are used, then lachrymator release is reduced, but preparation time and process complexity increase

Engineering Contradiction:

Improvelachrymator particle concentrationVSAvoidpreparation time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the smartphone emit radio frequency waves during the onion cutting process itself, rather than requiring preparatory chilling. The electromagnetic field is activated in advance of or during particle release to neutralize lachrymator particles as they are generated, eliminating the need for time-consuming pre-preparation steps while maintaining effectiveness.

Inventive Principle:

Principle #10Preliminary action

4Object-affected harmful factors

If food processor is used to enclose cutting, then particle ejection is reduced, but device complexity and space requirements increase

Engineering Contradiction:

Improveparticle ejection controlVSAvoidequipment and space requirements

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical enclosure system (food processor housing) with an electromagnetic field-based solution. Instead of physically containing and processing the onion to control particle ejection, the smartphone emits radio frequency waves that neutralize lachrymator particles in the air, eliminating the need for specialized processing equipment and associated space requirements.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
