Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high-pressure union pipeline with threaded connection and flange rigid connection is adopted, then connection strength is improved, but installation complexity increases and safety performance deteriorates due to hammering and beating requirements
Solution Approach 1:
The patent replaces rigid fixed connections with universal connecting pipe joints that allow dynamic adjustment. The joints enable the pipeline to adapt to position and orientation changes through rotation and angle adjustment, eliminating the need for complex threaded connections and hammering operations while maintaining connection strength.
Solution Approach 2:
The universal connecting pipe joint changes the connection parameters from fixed to adjustable. By allowing rotation and angle modification, the system can adapt to different installation requirements without compromising structural strength, thereby simplifying the installation process and improving safety.
2Stability of the object's composition
If rigid connection is adopted, then connection stability is improved, but adaptability deteriorates as distance and position adjustments become complicated requiring multiple angle joints and straight tubes
Solution Approach 1:
The universal connecting pipe joint serves multiple functions: it provides stable connection while simultaneously enabling position and orientation adjustments. This multi-functional component replaces the need for multiple separate angle joints and straight tubes, simplifying the overall structure while maintaining both stability and adaptability.
Solution Approach 2:
The joint introduces dynamic adjustment capability to the previously static rigid connection. The ability to rotate and adjust angles allows the pipeline to adapt to various distances and positions while maintaining connection stability, eliminating the need for complex multi-component assemblies.
3Adaptability or versatility
If multiple angle joints and straight tubes are used for direction changes, then connection adaptability is improved, but device complexity and fluid transportation efficiency deteriorate
Solution Approach 1:
The patent merges multiple separate components (angle joints, straight tubes) into a single universal connecting pipe joint. This integrated design provides the same direction change capability while significantly reducing the number of parts, simplifying the structure, and improving fluid transportation efficiency by eliminating multiple connection interfaces.
4Strength
If traditional fracturing pipeline connection is adopted, then structural strength is improved, but installation time and energy consumption increase due to complicated operations
Solution Approach 1:
The universal connecting pipe joint enables dynamic adjustment during installation, allowing workers to accommodate position and orientation variations without complex threading and alignment operations. This reduces installation time and energy consumption while maintaining the required structural strength through the joint's robust design.

AI summary
A hard pipe connecting device and manifold system are disclosed that solve technical problems of existing fracturing pipelines, such as poor safety performance, too many connecting parts, inconvenient and ineffective connection between the parts, complicated installation structure, and difficulty to adjust the distance and the angle. In order to solve the technical problems, the hard pipe connecting device includes at least one non-concentric connecting pipe joint, which includes a pipe body and first flanges at opposite ends of the pipe body. The two first flanges are parallel to each other with a distance difference h, where h>0.
