Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional bending performance tests are conducted at room temperature in laboratories, then the test conditions are controlled and simple, but the influence of complex marine climate environment and bending load collaborative action cannot be embodied
Solution Approach 1:
The patent transitions from static laboratory testing to dynamic outdoor marine environment testing, where the bending load device operates in real marine climate conditions with varying temperature, humidity, salt fog, and solar radiation. This dynamic approach captures the collaborative degradation effects that static tests cannot reveal.
Solution Approach 2:
The patent introduces a bending load device as an intermediary component that applies controlled loads to test pieces while positioned in the outdoor marine environment. This intermediary enables the coupling of mechanical loading with environmental exposure, bridging the gap between controlled testing and real-world conditions.
2Adaptability or versatility
If natural environment tests are conducted without applying load, then the environmental exposure is realistic, but the influence of load on performance degradation is not considered
Solution Approach 1:
The patent merges environmental exposure testing with mechanical bending load testing into a single integrated test system. The bending load device applies static or dynamic loads to test pieces while simultaneously exposing them to marine climate conditions, capturing the synergistic degradation effects of both environmental factors and mechanical stress.
Solution Approach 2:
The patent varies the bending load parameters (static load magnitude, dynamic load amplitude, frequency, and waveform) to simulate different service conditions. By changing these parameters, the test can evaluate material performance under various operational scenarios while maintaining realistic environmental exposure.
3Temperature
If laboratory tests are conducted to determine bending performance at different temperatures, then the temperature control is precise, but the collaborative action of complex climate environment and bending load cannot be embodied
Solution Approach 1:
The patent moves the test from a controlled laboratory environment to the outdoor marine environment, adding dimensions of humidity, salt fog, solar radiation, and temperature cycling that cannot be replicated in standard laboratories. This dimensional expansion captures the full complexity of marine climate effects on material degradation.
Solution Approach 2:
The patent implements continuous outdoor testing where the bending load device operates uninterrupted in the marine environment, allowing simultaneous evaluation of multiple environmental factors and their interaction with mechanical loading. This continuous action provides comprehensive data on material degradation under realistic service conditions.

AI summary
A marine climate environment-bending load collaborative acceleration test method is provided, including conducting a static bending load loading test in an outdoor marine climate environment, conducting an alternate cycle of a dynamic bending load loading test in the outdoor marine climate environment and a test in the outdoor marine climate environment, and conducting an alternate cycle of the dynamic bending load loading test and the static bending load loading test in the outdoor marine climate environment. In the present disclosure, an acceleration rate of the marine climate environment-bending load collaborative acceleration test reaches over 8 times that of the test in the outdoor marine climate environment by taking the maximum bending force as an evaluation index, which may achieve a change from a static test to a static and dynamic combined test for examining and evaluating the environmental adaptability of the metal material.
