Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple jet interaction-type fluidic oscillators are used to achieve multidirectional fluid output, then the fluid can be distributed in multiple directions, but the device complexity increases and the oscillators operate independently without coordination

Engineering Contradiction:

Improvemultidirectional fluid outputVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple fluidic oscillator functions into a single integrated device with a shared interaction chamber. Multiple inlet ports and outlet ports are combined within one chamber, allowing multidirectional fluid output while eliminating the need for separate oscillators. This integration reduces device complexity and enables coordinated operation of all fluid streams through a single oscillation mechanism.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The interaction chamber serves multiple functions simultaneously: it receives fluid from multiple inlets, generates oscillations, and distributes fluid to multiple outlets. This multi-functional design allows a single device to perform what previously required multiple specialized oscillators, achieving multidirectional output without increasing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple jet interaction-type fluidic oscillators are used to achieve multidirectional fluid output, then the fluid can be distributed in multiple directions, but the number of components and space required increases

Engineering Contradiction:

Improvemultidirectional fluid outputVSAvoidspace required

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent nests multiple fluid pathways within a single interaction chamber. Multiple inlet ports and outlet ports are arranged within the same chamber volume, with fluid streams nested together in the interaction region. This nesting approach achieves multidirectional output while minimizing the space required, as all functional elements are contained within one compact chamber rather than requiring separate oscillator units.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If multiple jet interaction-type fluidic oscillators are used to achieve multidirectional fluid output, then the fluid can be distributed in multiple directions, but each oscillator operates independently without synchronized coordination

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent segments the fluid flow paths while maintaining a unified oscillation source. Multiple inlet ports and outlet ports are segmented within the interaction chamber, allowing independent control of fluid entry and exit points. However, all segments share the same oscillation mechanism, ensuring synchronized coordination of all fluid streams without requiring multiple independent oscillators.

Inventive Principle:

Principle #1Segmentation

Function Achieved in This Case

The device achieves 360° output coverage with coordinated fluid streams, eliminating the need for multiple oscillators and ensuring synchronized fluid distribution.

Implementation Method 1

The first inlet fluid stream collides with the second inlet fluid stream within the interaction chamber. The collision of the first inlet fluid stream with the second inlet fluid stream causes the first outlet fluid stream to sweep as the first outlet fluid stream is discharged from the first outlet nozzle and causes the second outlet fluid stream to sweep as the second outlet fluid stream is discharged from the second outlet nozzle.
