Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the liquid inlet is designed to aim directly at the filter core, then the filtering function is achieved, but the high pressure from non-filtered water damages the filter core and reduces its lifespan

Engineering Contradiction:
Improvefilter core lifespanVSAvoidhigh pressure damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A vortex generator is introduced as an intermediary device between the liquid inlet and the filter core. The vortex generator converts the high-pressure direct flow into a rotating flow pattern, reducing the impact pressure on the filter core while maintaining effective filtering. This mediator component resolves the contradiction by transforming the harmful high-pressure flow into a gentler rotational flow.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful high-pressure direct flow into a beneficial rotational flow pattern using the vortex generator. The vortex generator utilizes the incoming high-pressure water to create rotation, which then gently contacts the filter core, transforming the harmful impact force into useful rotational motion that enhances filtering while protecting the filter core.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Reliability

If the liquid inlet aims at the filter core, then filtering is achieved, but impurities are washed away from the filter core reducing filtered liquid quality

Engineering Contradiction:
Improvefiltered liquid qualityVSAvoidimpurity washout
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The vortex generator serves as a mediator that controls the flow pattern before it reaches the filter core. By creating a rotational flow pattern, it prevents direct high-pressure impact that would wash impurities away, while still allowing effective filtration to occur.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the flow parameters from a direct high-pressure linear flow to a rotational flow pattern with reduced impact pressure. This parameter transformation maintains the filtering function while preventing impurity washout, thereby improving filtered liquid quality.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the wastewater discharging hole is located at the lateral side of the container barrel, then the structure is simple, but wastewater cannot be completely discharged

Engineering Contradiction:
Improvewastewater discharge completenessVSAvoiddischarging structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the discharge location from a lateral position to a bottom position, utilizing the vertical dimension to achieve complete drainage. By placing the discharge hole at the bottom of the container barrel, gravity can fully assist the discharge process, ensuring complete wastewater removal without requiring complex additional structures.

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

Solution Approach 2:

The bottom discharge hole creates a equipotential discharge point where the wastewater level equalizes with the discharge location, allowing complete drainage. This positioning ensures that wastewater can flow out completely under gravity without leaving residual water in the container.

Inventive Principle:
Principle #12Equipotentiality
