Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If a conventional nozzle design with separate valve attachment is used, then the nozzle structure is simpler, but the liquid consumption cannot be precisely controlled and the jet discharge duration cannot be precisely controlled

Engineering Contradiction:
Improveliquid consumptionVSAvoidnozzle structure
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The patent merges the nozzle body and valve body into a single integrated structure where the nozzle is directly formed within the valve body. The nozzle outlet opens into the valve chamber, and the valve stem directly controls fluid flow to the nozzle. This integration eliminates separate attachment components and enables precise control of liquid consumption and jet discharge duration through the valve mechanism.

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If a conventional nozzle with separate valve attachment is used, then the manufacturing process is simpler, but the jet alignment cannot be precisely adjusted

Engineering Contradiction:
Improvejet alignmentVSAvoidmanufacturing process
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent incorporates adjusting screws that enable dynamic alignment of the nozzle relative to the valve outlet. The nozzle can be positioned in different angular orientations and radial positions through these adjustment mechanisms, allowing precise jet alignment to be achieved and maintained. This dynamic adjustability is built into the integrated structure during manufacturing.

Inventive Principle:
Principle #15Dynamics

3Loss of time

If a nozzle with large internal flow volume is used, then the nozzle can handle higher flow rates, but the shut-off response time is slower and the jet discharge cannot be precisely controlled

Engineering Contradiction:
Improveshut-off response timeVSAvoidinternal flow volume
Core Design Contradiction:
Loss of timeVSQuantity of substance

Solution Approach 1:

The patent segments the flow control function by placing the nozzle outlet directly within the valve chamber, where the valve stem can immediately intercept and stop fluid flow. This segmentation of the flow path ensures that when the valve closes, the jet discharge is immediately terminated without the delay associated with draining large internal volumes. The integrated design minimizes the volume between the valve closure point and the nozzle outlet.

Inventive Principle:
Principle #1Segmentation

4Stability of the object's composition

If an angled inlet direction into the nozzle body is used, then the connection to the supply line is simpler, but the flow laminarity is poor and turbulence increases

Engineering Contradiction:
Improveflow laminarityVSAvoidnozzle body structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent introduces a flow rectifier as an intermediary component positioned between the angled supply line connection and the nozzle outlet. This rectifier element straightens and stabilizes the fluid flow, converting the angled, potentially turbulent flow from the supply line into a laminar flow pattern suitable for precise jet discharge. The rectifier mediates between the simplified angled connection and the requirement for flow stability.

Inventive Principle:
Principle #24Intermediary (Mediator)
