Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a fan is used to blow air toward the flotage, then the flotage can be moved and collected, but the power consumption increases and processing speed is limited

Engineering Contradiction:
Improveprocessing speedVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the mechanical fan-based air blowing system with an electric field-based flotage collection system. Instead of using a fan to generate air flow to move flotage, the invention uses electrodes to generate electric fields that directly attract and collect flotage particles, thereby eliminating the need for mechanical air movement while improving power efficiency and processing speed.

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

Solution Approach 2:

The patent changes the fundamental parameter of flotage collection from mechanical air flow to electric field attraction. By switching from a fan-driven system to an electrode-based system, the method transforms how flotage is moved and collected, enabling faster processing with lower power consumption by directly attracting charged particles to collection electrodes.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a dense filter is used to remove flotage, then the filtration efficiency is improved, but the wind resistance increases and processing power is limited

Engineering Contradiction:
Improvefiltration efficiencyVSAvoidprocessing power
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical filtration system with an electric field-based collection system. Instead of forcing air through a dense filter that creates high resistance, the invention uses electrodes to generate electric fields that attract and collect flotage particles directly, eliminating the need for high-pressure air flow through filters and thereby maintaining high processing power.

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

Solution Approach 2:

The patent extracts the core function of flotage removal from the mechanical filtration process and implements it separately through electric field attraction. By separating the flotage collection function from the air flow generation function, the system can use a less restrictive air flow path while maintaining effective flotage removal through electrode attraction.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If a large housing is used to accommodate the fan and filter system, then the flotage can be trapped, but the device size increases and installation becomes difficult

Engineering Contradiction:
Improveflotage trapping capabilityVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent replaces the bulky mechanical system comprising fan and filter housing with a compact electrode-based system. The electrode configuration can be arranged in a much smaller space while achieving the same or better flotage collection efficiency, thereby significantly reducing the overall device volume and facilitating easier installation.

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

Solution Approach 2:

The patent transitions from a three-dimensional bulky housing structure to a more compact electrode arrangement that can be configured in various spatial dimensions. The electrode system can be arranged in planes or layers that occupy less volumetric space while maintaining effective collection coverage, thereby reducing device footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
