Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional methods are used to analyze fatigue performance of K-type parts, then large test forces can be applied, but the specimen preparation becomes complex, energy consumption increases, and connecting parts are prone to breakage
Solution Approach 1:
The detection device segments the testing system into separate positioning assemblies for the main pipe and branch pipes. Each assembly independently positions and applies force to its respective pipe component, eliminating the need for complex specimen preparation while maintaining the capability to apply large test forces for fatigue performance analysis.
2Reliability
If conventional testing methods are used for complex welded structures, then fatigue performance can be analyzed, but the test process consumes high energy and has complex load application requirements
Solution Approach 1:
The positioning assemblies are designed with adjustable and movable components that can dynamically adapt to different pipe positions and orientations. This dynamic capability allows the system to apply complex load conditions for fatigue analysis while optimizing energy consumption through efficient, adaptive positioning rather than rigid, energy-intensive setups.
3Measurement precision
If the main pipe is connected to the oil cylinder for force application, then the mechanical properties can be measured, but the detection efficiency decreases and labor intensity increases
Solution Approach 1:
The positioning assembly acts as an intermediary between the oil cylinder and the main pipe. Instead of directly connecting the main pipe to the oil cylinder, the positioning assembly mediates the force transmission, enabling accurate mechanical property measurement while simplifying the connection process and improving detection efficiency by reducing manual intervention.
4Ease of operation
If branch pipes are not positioned properly, then the detection process is simpler, but safety performance decreases due to potential pipe dislodgment
Solution Approach 1:
The branch pipe positioning assembly performs preliminary positioning and securing of the branch pipes before the detection process begins. This preliminary action ensures that branch pipes are properly positioned and secured to prevent dislodgment during testing, maintaining safety performance while keeping the detection process simple and straightforward.

AI summary
A detection device includes a frame body and a main pipe positioning assembly, a branch pipe positioning assembly, and a first driving assembly disposed on the frame body. One side of the frame body is provided with an opening. The branch pipe positioning assembly is disposed inside the opening. The first driving assembly adjusts the branch pipe positioning assembly, so that the branch pipe positioning assembly is adapted to positions of the two branch pipes. During detection, the branch pipes are located in the opening, the main pipe positioning assembly connects two ends of the main pipe, and the branch pipe positioning assembly connects the two branch pipes. Two limiting members are slidably disposed on the frame body to open and close the opening, and the limiting members abut against an outer wall of the main pipe, such that the main pipe is located inside or outside the opening.
