Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sizes and types of APT probes are manufactured and stocked to accommodate different pipe diameters and connection types, then customer application coverage is improved, but manufacturing complexity and lead times increase

Engineering Contradiction:
Improveapplication coverageVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal APT probe design with standardized connection interfaces and modular components that can be configured for different pipe diameters and connection types through a family of interchangeable parts rather than manufacturing entirely different probe models. This allows a single base design to serve multiple applications.

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

Solution Approach 2:

The probe is divided into modular segments including the probe body, connection interface, and sensing elements that can be independently manufactured and assembled. This segmentation allows for standardized production of common components while enabling customization through different combinations of modules for various applications.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple sizes and types of APT probes are manufactured and stocked to accommodate different pipe diameters and connection types, then customer application coverage is improved, but lead times increase

Engineering Contradiction:
Improveapplication coverageVSAvoidlead times
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs preliminary action by pre-manufacturing and stocking modular probe components and connection interfaces in standardized configurations. This allows the base probe body to be produced in advance while customization is achieved through rapid assembly of pre-prepared modules, significantly reducing final lead times.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The design incorporates dynamic configurability where the probe can be adapted to different applications through interchangeable connection interfaces and adjustable components. This dynamic approach allows a single probe platform to be quickly reconfigured for different pipe diameters and connection types without requiring multiple static probe designs.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple sizes and types of APT probes are manufactured to accommodate different pipe diameters and connection types, then customer application coverage is improved, but manufacturing costs increase

Engineering Contradiction:
Improveapplication coverageVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent reduces manufacturing costs by implementing a universal probe platform that can be produced using standardized processes and materials. The same base design serves multiple applications, eliminating the need for expensive tooling and production setups for each different probe size and type.

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

Solution Approach 2:

The patent merges the production of different probe variants into a single manufacturing line by using modular components that can be assembled in different configurations. This consolidation allows for economies of scale in producing common components while still providing customization through final assembly variations.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A customizable length averaging pitot tube (APT) probe for insertion into a confined conduit is disclosed. The APT probe includes a probe portion, configured to be inserted into the confined conduit, which includes longitudinally extending upstream, downstream and middle surfaces to form first and second fluid carrying plenums within the APT probe portion. A plurality of longitudinally arranged openings are disposed along the length of the upstream surface with each opening in fluid communication with the first fluid carrying plenum. A plurality of longitudinally arranged openings are disposed along the length of the downstream surface with each opening in fluid communication with the second fluid carrying plenum. A cap is affixed to an end of the APT probe portion to isolate the first and second fluid carrying plenums. An elongated body is coupled to the APT probe portion and provides fluid passageways fluidically coupled to the first and second plenums.
