Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a filter is used to remove dust from air, then dust removal performance is improved, but the device requires frequent washing or replacement of the filter, limiting continuous operation

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidmaintenance frequency
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention extracts and removes the filter component from the dust removal system entirely. Instead of using a filter that accumulates dust and requires maintenance, the system uses expansion pressure to separate dust from air, allowing dust to be discharged without any filtering medium that would need washing or replacement.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system achieves self-cleaning operation where dust is automatically discharged through the expansion pressure mechanism. The dust collection chamber accumulates dust until it reaches a dischargeable state, at which point the expansion pressure automatically expels the dust without requiring manual intervention for filter maintenance.

Inventive Principle:
Principle #25Self-service

2Reliability

If the supplying pipe and outlet are positioned close to each other, then the device structure is compact, but the expansion pressure cannot effectively accelerate dust separation

Engineering Contradiction:
Improvedust separation efficiencyVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The invention optimizes the spatial arrangement by positioning the supplying pipe and outlet at opposite ends of the inlet chamber rather than close to each other. This linear arrangement maximizes the expansion pressure path length, allowing the pressure to act over a longer distance to effectively separate dust particles from air before discharge.

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

AI summary

The present invention discloses a dust removal device using expansion pressure. A dust removal device using expansion pressure according to one embodiment may comprise an inlet chamber allowing mixed air including dust to flow inside and including an outlet for discharging the dust downward; a dust collecting chamber disposed at a bottom of the inlet chamber and sealed in a state of communicating with the inlet chamber and the outlet to collect the dust discharged through the outlet; a supplying pipe entering into an inside of the inlet chamber and extending toward the outlet to supply the mixed air into the inlet chamber; a first blower providing a blowing force for sucking in the mixed air and supplying the mixed air through the supplying pipe; an air exhaust duct connected to communicate with the inlet chamber to guide air separated from the dust to be discharged to outside, wherein a communication part of the air exhaust duct, which communicates with the inlet chamber, has a certain size allowing the inlet chamber to generate an expansion pressure inside, and a second blower providing a blowing force to discharge the air inside the inlet chamber to the outside through the air exhaust duct, wherein the supplying pipe and the outlet are spaced apart from each other, and a separation distance between the supplying pipe and the outlet is longer than a range that the mixed air propelled from the supplying pipe can reach to, so that the expansion pressure of the mixed air supplied to the inlet chamber accelerates separation action caused by specific gravity difference between the air and the dust.
