Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If high pressure compressed air is applied against the air flow to clean filter bags, then cleaning force is improved, but filter bags deteriorate quickly and require frequent replacement

Engineering Contradiction:

Improvecleaning forceVSAvoidfilter bag lifespan

Core Design Contradiction:

ForceVSDuration of action of stationary object

Solution Approach 1:

The invention changes the pressure parameter from high pressure (>6 bar) to low pressure (<3 bar) cleaning air, and introduces a periodic pulsing mechanism that creates ripple effects on filter bags. This resolves the contradiction by achieving effective cleaning through pressure variation and wave propagation rather than sustained high pressure, thereby reducing mechanical damage to filter bags while maintaining cleaning force.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention employs periodic pulsing of cleaning air to generate ripple effects that propagate across filter bag surfaces. This periodic action creates intermittent cleaning forces that are effective at removing dust while allowing filter bags to recover between pulses, reducing cumulative mechanical stress and extending filter bag lifespan compared to continuous high-pressure application.

Inventive Principle:

Principle #19Periodic action

2Productivity

If high pressure compressed air is used for filter cleaning, then dust removal capability is improved, but energy consumption increases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The invention reduces the pressure parameter from >6 bar to <3 bar and introduces periodic pulsing with specific frequency and duty cycle. This resolves the contradiction by achieving dust removal through the cumulative effect of periodic pressure variations and ripple propagation rather than sustained high pressure, significantly reducing the energy required for cleaning operations while maintaining effective dust removal capability.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If frequent cleaning is performed to maintain filter performance, then filtering capacity is improved, but filter bags deteriorate faster due to high frequency cleaning pulses

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSDuration of action of stationary object

Solution Approach 1:

The invention changes the cleaning parameter from high pressure sustained application to low pressure periodic pulsing with controlled duty cycle. This allows more frequent cleaning intervals to be used effectively for maintaining filtering capacity, while the low pressure and periodic nature of the cleaning pulses prevent cumulative mechanical damage that would occur with high-frequency high-pressure cleaning, thus resolving the contradiction between filtering capacity maintenance and filter bag durability.

AI summary

Industrial air filtering technology and a new component for their internal cleaning system are disclosed leading to dramatic increase in system cleaning efficiency as well as energy efficiency. A telescopic cleaning mechanism is able to move at the front of filtering cassette bodies via linear guiding rollers and servo motors transfer cleaning air into the cassettes and extends till to the end of surfaces for enabling better cleaning functionality. A suction blockage paddle further enhances cleaning performance via avoiding suction power only at the right time that is needed.
