Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mechanical cleaning mechanisms are used to clean the inner surface of tubular collecting electrodes, then cleaning effectiveness is improved, but device complexity and cost increase significantly

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidmechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the discharge electrode with the cleaning function by integrating a cleaning device (brush or wiper) directly onto the discharge electrode. This merging of functions eliminates the need for separate cleaning mechanisms, reducing device complexity while maintaining cleaning effectiveness. The discharge electrode serves dual purposes: electrical discharge for particle separation and mechanical cleaning when moved radially.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The discharge electrode is designed to perform multiple functions: it generates the electrical field for electrostatic separation and simultaneously acts as a carrier for the cleaning device. By making the discharge electrode multi-functional, the patent eliminates the need for dedicated cleaning mechanisms, thereby reducing overall system complexity and cost.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If complex mechanisms are used for cleaning movement, then cleaning coverage is improved, but expenditure and cost increase

Engineering Contradiction:

Improvecleaning coverageVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The cleaning function is merged with the discharge electrode structure, eliminating the need for separate cleaning mechanisms. The cleaning device is integrated onto the discharge electrode, which is already present in the system, thereby reducing manufacturing costs while achieving complete cleaning coverage of the collecting electrode inner surface.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The discharge electrode, by its own radial movement, performs the cleaning function without requiring external complex mechanisms. The system uses its existing moving component (discharge electrode) to serve the additional function of cleaning, thereby avoiding additional manufacturing costs for separate cleaning mechanisms.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If radial movement of discharge electrode is implemented, then cleaning accessibility is improved, but mechanism complexity increases

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning function is combined with the existing radial movement capability of the discharge electrode. By integrating the cleaning device onto the discharge electrode, the patent utilizes the already-present radial movement mechanism to achieve cleaning accessibility, avoiding the need for additional complex movement mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

Solution Approach 1:

The patent employs periodic cleaning action by moving the discharge electrode radially at intervals to clean the collecting electrode surfaces. This periodic movement, combined with the integrated cleaning device, achieves effective dust removal while minimizing interruption to the overall filtration operation, thereby maintaining productivity.

Inventive Principle:

AI summary

An electrostatic filter for the separation of dust particles has collecting electrodes fixed in a housing through which the gas flows and discharge electrodes arranged parallel to them and held stretched between insulators. For the cleaning of the collecting electrodes, a cleaning equipment is fixed to a cable having the discharge electrodes, which can be moved along the surface of the collecting electrodes to be cleaned by using a pulling device having a coiling drum.
