Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a custom-built header delivery system is used for pigging operations, then the system can be tailored to specific furnace configurations, but the development time and cost increase significantly

Engineering Contradiction:

Solution Approach 1:

The patent applies universality by designing a standardized header delivery system that can be used across multiple furnace configurations. The system includes universal components such as a standardized base assembly, rotation apparatus, and launcher assembly that can accommodate different header pipe sizes and process tube angular positions without requiring custom fabrication. This allows the same system design to serve multiple functions across different furnace types, thereby reducing development time while maintaining adaptability.

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

Solution Approach 2:

The patent applies dynamics through the rotation apparatus that enables the base assembly to rotate to different angular positions. This dynamic capability allows the launcher assembly to align with process tubes at various angular positions around the header pipe, providing adaptability to different furnace configurations without requiring multiple custom-built systems. The rotational mechanism enables the system to dynamically adjust to different operational requirements.

AI summary

A header delivery system and method for performing a pigging operation on a process tube connected at an angle to a header pipe. The header delivery system includes a base assembly coupled to a rotation assembly. The base assembly has a frame member supporting a launcher pipe coupled to a tube coupler and a jack apparatus. The rotation assembly is configured to position the base assembly with respect to the rotation assembly to adjust an angular position of the base assembly. The header delivery system may be aligned with a process tube in the header pipe and the jack apparatus may position the tube coupler from a first retracted position to an extended position to form a seal between the tube coupler and the first process tube. A service operation may be performed on the first process tube with the tube coupler in the extended position.
