Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stress or pressure

If a pump is used to apply pressure to a system, then pressure can be generated, but pressure variance occurs due to pump design limitations

Engineering Contradiction:
ImprovepressureVSAvoidpressure variance
Core Design Contradiction:
Stress or pressureVSReliability

Solution Approach 1:

A pressure regulation device is introduced as an intermediary between the pump and the system. This device includes a pressure chamber with a bypass channel and adjustable opening that mediates the pressure transmission, reducing pump-induced pressure variance before it reaches the system

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The bypass opening area in the pressure regulation device is dynamically adjusted to change the bypass flow rate. By varying this parameter, the device compensates for pump pressure fluctuations and maintains stable system pressure

Inventive Principle:
Principle #35Parameter changes

2Stress or pressure

If existing pressure control methods are used, then pressure adjustment is possible, but the systems are technically complex and expensive

Engineering Contradiction:
Improvepressure controlVSAvoidsystem complexity
Core Design Contradiction:
Stress or pressureVSDevice complexity

Solution Approach 1:

Multiple pressure control functions (pressure reduction, variance reduction, and regulation) are merged into a single integrated device. The pressure regulation device combines a bypass channel, adjustable opening, and pressure chamber into one compact unit, eliminating the need for multiple separate components

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The pressure regulation device performs multiple functions simultaneously: it reduces pressure, minimizes pressure variance, and provides adjustable pressure control. This multi-functional design replaces what would traditionally require several separate devices, simplifying the overall system

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If high pressure is applied to damaged areas, then filling effectiveness improves, but damage to the object being repaired increases

Engineering Contradiction:
Improvefilling effectivenessVSAvoidobject damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The pressure regulation device provides continuous pressure regulation based on system conditions. The adjustable opening allows the bypass flow to respond to pressure changes, ensuring that optimal pressure is maintained without exceeding damage thresholds

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The bypass opening is designed to be adjustable, allowing dynamic adaptation of the pressure regulation. This enables the system to maintain optimal pressure for effective filling while preventing excessive pressure that could damage the repaired object

Inventive Principle:
Principle #15Dynamics

AI summary

The invention presented relates to a device (100) for setting a pressure in a system. The device (100) comprises at least one movable adjustment unit (109), having at least one opening, and a fluid channel (101). The fluid channel (101) comprises a main opening (105), having a flow region for the outflow of a main stream (101b) of fluid to be conveyed through the fluid channel (101), and a secondary-stream opening (107), having a flow region for the outflow of a secondary stream (102a) of the fluid to be conveyed through the fluid channel (101), to an outer environment of the device (100). The adjustment unit (109) is configured to at least partially overlie the secondary-stream opening (107) in a working position and thereby reduce the flow region of the secondary-stream opening (107).
