Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor plate pullout force measurement test devices cannot simulate the pullout failure process of double anchor plates under varying embedding depths and inclination angles, failing to account for the mutual feedback reaction between fixed frames and anchor plates, and do not accurately represent the complex seabed conditions.
Innovation Solution
A pullout force measurement test device that includes a support frame, winch, lifting plate, upper and lower hanging ropes, and anchor plate mechanisms with pulley assemblies and vertical slits, allowing for adjustable angles and depths to simulate the pullout of double anchor plates, enabling the measurement of pullout forces and failure modes under different conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct pullout force application to anchor plates is used, then test simplicity is improved, but simulation accuracy of marine pipeline anchoring system is worsened
Solution Approach 1:
The patent introduces a fixed frame as an intermediary component between the anchor plates and the pullout force application system. The fixed frame simulates the actual marine pipeline anchoring structure, creating a more realistic test environment. The force is applied through the fixed frame rather than directly to the anchor plates, which better represents the actual loading conditions and improves simulation accuracy while maintaining test feasibility
Solution Approach 2:
The patent creates a scaled-down indoor model that copies the essential features of the actual marine pipeline anchoring system. The model includes proportional representations of the fixed frames, anchor plates, and soil medium, allowing accurate simulation of the full-scale system behavior under controlled laboratory conditions
2Device complexity
If fixed embedding depth and angle are used in test device, then device complexity is reduced, but adaptability to different seabed conditions is worsened
Solution Approach 1:
The patent incorporates adjustable mechanisms that allow the embedding depth and inclination angle of the anchor plates to be dynamically changed during testing. The fixed frame structure includes movable components and adjustable fixtures that enable researchers to configure the test setup according to different seabed conditions, transforming a static device into a dynamic, adaptable system
Solution Approach 2:
The test device is designed with universal features that allow it to accommodate various testing scenarios. The adjustable embedding depth and angle capabilities, combined with the modular fixed frame structure, enable the same device to simulate multiple seabed conditions and anchoring configurations, making it a multi-functional tool for comprehensive anchor plate performance evaluation
