Solution Overview
Problem
Existing systems face challenges in maintaining precise and uniform pressure, particularly in applications like window repair, where variance in pressure can cause damage, and existing solutions are either complex or expensive.
Innovation Solution
A device with a movable adjustment unit and fluid channel that allows for controlled branching of fluid flow into a secondary stream, reducing input pressure variance by overlaying a bypass opening, enabling precise adjustment of working pressure through a main and secondary flow system.
Engineering Contradictions & Design Principles
Engineering 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
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
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
2Stress or pressure
If existing pressure control methods are used, then pressure adjustment is possible, but the systems are technically complex and expensive
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
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
3Productivity
If high pressure is applied to damaged areas, then filling effectiveness improves, but damage to the object being repaired increases
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
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

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).
