Problem

Existing fluid delivery systems struggle to handle extreme flow rates and high temperatures in semiconductor processing and petrochemical applications, with limitations in conduit design and sealing methods leading to inefficiencies and maintenance challenges.

Innovation Solution

The development of a flow substrate with adjustable conduit sizes and sealing mechanisms, including integrated or individual caps, to accommodate asymmetric port placements and provide secure, leak-proof connections for fluid handling components, suitable for extreme flow rates and temperatures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fluid delivery systems are used, then standard fluid handling is achieved, but they cannot handle extreme flow rates and high temperatures

Engineering Contradiction:
Improveperformance under extreme conditionsVSAvoidapplicability to extreme flow rate and temperature applications
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the physical parameters of the fluid delivery system by using a solid block substrate with internally formed conduits of varying cross-sectional areas, allowing the system to handle extreme flow rates and temperatures that conventional systems cannot accommodate

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses composite construction with a solid block substrate material that can withstand extreme temperatures and pressures, combined with separately attachable fluid handling components, creating a system that maintains reliability under extreme conditions

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If standardized interface designs are used, then modular assembly is simplified, but conduit size adjustment for different flow rates is limited

Engineering Contradiction:
Improvemodular assembly simplicityVSAvoidconduit size variability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by forming conduits with different cross-sectional areas at different locations within the solid block substrate, allowing each conduit to be optimized for specific flow rate requirements while maintaining the overall modular structure

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention enables dynamic adaptability by allowing the modular fluid handling components to be attached and detached from the substrate, with the substrate itself providing variable conduit sizes that can be selected based on flow rate requirements

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If deformable gasket sealing is used, then component attachment is simplified, but sealing reliability at high temperatures is compromised

Engineering Contradiction:
Improvecomponent attachment simplicityVSAvoidsealing performance at high temperature
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent employs disposable or replaceable sealing elements such as O-rings or gaskets that can be easily installed and replaced, providing simple attachment while maintaining sealing reliability through periodic replacement rather than permanent high-temperature seals

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Reliability

If metallic seals are used, then sealing durability is improved, but ionic contamination of fluid occurs

Engineering Contradiction:
Improvesealing durabilityVSAvoidionic contamination
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention applies different material qualities in different locations - using non-metallic sealing materials (such as elastomers or polymers) at the sealing interfaces to prevent ionic contamination, while using metallic structural components for durability and strength in non-contact areas

Inventive Principle:
Principle #3Local quality
