Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a standalone suction device is used to capture aerosols, then aerosol capture capability is improved, but office space requirement increases and device mobility decreases

Engineering Contradiction:

Improveaerosol capture capabilityVSAvoidoffice space requirement

Core Design Contradiction:

Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The patent combines aerosol suction and liquid suction capabilities into a single integrated device. The housing contains both an aerosol suction pathway with aerosol suction bore and a liquid suction pathway with liquid suction bore, eliminating the need for separate standalone aerosol capture devices and reducing office space requirements.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device performs multiple functions simultaneously: it captures aerosols through the aerosol suction pathway and removes liquids through the liquid suction pathway. This multi-functional design replaces multiple single-function devices, improving space efficiency while maintaining comprehensive suction capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If a handheld aerosol suction device is used, then aerosol capture capability is improved, but practitioner fatigue increases and operational complexity increases

Engineering Contradiction:

Improveaerosol capture capabilityVSAvoidpractitioner fatigue

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The device merges aerosol suction and liquid suction into a single unit that can be held and operated together. The housing integrates both suction pathways with their respective bores, allowing the practitioner to control both functions with one hand, reducing fatigue compared to managing separate devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The handheld device performs both aerosol capture and liquid removal functions simultaneously through its integrated pathways. This multi-functionality in a single handheld unit simplifies operation compared to managing multiple separate devices, reducing practitioner burden and fatigue.

Inventive Principle:

Principle #6Universality (Multi-functionality)

If traditional suction devices are used, then liquid removal capability is maintained, but aerosol capture capability is insufficient

Engineering Contradiction:

Improveliquid removal capabilityVSAvoidaerosol capture capability

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The device combines traditional liquid suction functionality with added aerosol suction capability. The housing contains both a liquid suction pathway with liquid suction bore and an aerosol suction pathway with aerosol suction bore, allowing simultaneous performance of both functions that were previously handled by separate devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device serves as both a traditional liquid suction device and an aerosol capture device through its dual pathway system. The liquid suction pathway maintains effective liquid removal while the added aerosol suction pathway provides aerosol capture capability, creating a universal device that handles both functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)
