Offshore Pile Anti-Impact Structure with Dynamic Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Offshore pile foundations face inadequate impact absorption due to fixed buffer materials that are not flexible enough, leading to insufficient protection against ship impacts.
Innovation Solution
A pile foundation with an anti-impact structure featuring impact absorption rollers, including a support shaft mechanism with elastic absorbers and sliding mechanisms, which allows for rotation and sliding on hoops to distribute and reduce impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed buffer materials are arranged around the pile foundation, then the structure provides basic impact protection, but the anti-impact effect is insufficient and the materials cannot be moved or adjusted
Solution Approach 1:
The patent transforms the static buffer materials into dynamic movable rollers that can rotate and slide along the pile foundation. The rollers are supported by shaft mechanisms and can move freely to adapt to impact forces from different directions, resolving the contradiction between providing reliable impact protection and maintaining flexibility.
Solution Approach 2:
The patent changes the physical state and movement parameters of the buffer materials from fixed to movable. By enabling the rollers to rotate and slide, the system gains adaptability in absorbing impacts from various angles while maintaining effective protection through the elastic properties of the roller materials.
2Adaptability or versatility
If movable rollers are introduced to improve flexibility, then the adaptability increases, but the device complexity increases with multiple mechanisms
Solution Approach 1:
The patent divides the anti-impact structure into modular components: multiple independent rollers, each with its own support shaft mechanism, sliding mechanism, and rotating mechanism. This segmentation allows each component to be simple in design while the overall system achieves high adaptability through the coordinated action of multiple modules.
Solution Approach 2:
The patent employs a nested structure where the roller is nested within the support shaft mechanism, which is nested within the sliding mechanism, which in turn is nested within the hoop structure. This nested design achieves complex functionality through layered simplicity, reducing overall system complexity while maintaining adaptability.
