Solution Overview
Problem
Conventional dredging systems face challenges in operating in confined spaces and require significant personnel and resources, especially when dealing with heterogeneous sediments, and often compromise fish fauna protection and safety due to their operational limitations.
Innovation Solution
A dredging system featuring a platform with flotation and anchoring winches, a dredging tool with adjustable lifting mechanisms, sediment detection systems, and remote control capabilities, utilizing either a bucket for heterogeneous sediments or a dredging pump for finer sediments, with advanced cable tensioning and control systems to manage sediment collection and unloading efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional dredging devices are used, then dredging operation can be performed, but they cannot operate in confined spaces with limited dimensions and drafts
Solution Approach 1:
The dredging system is divided into modular components: a platform unit, a dredging tool, and a control unit that can be operated remotely. This segmentation allows the system to be compact yet functional in confined spaces while maintaining dredging capability.
Solution Approach 2:
The invention transitions from traditional water-based dredging to air-based dredging by positioning the platform above the water surface and using aerial manipulation of the dredging tool. This dimensional change allows operation in confined water areas that would be inaccessible to conventional water-based dredgers.
2Productivity
If conventional dredging systems are deployed, then sediment removal can be achieved, but significant personnel and resources are required
Solution Approach 1:
The system incorporates automated control capabilities where the control unit can remotely operate the platform and dredging tool without requiring extensive on-site personnel. The automated navigation and dredging operations reduce manual intervention and resource requirements while maintaining productivity.
3Productivity
If mechanical dredging means are used, then sediment can be removed, but fish fauna protection is compromised and safety issues arise
Solution Approach 1:
The invention replaces traditional heavy mechanical dredging systems with a lighter, more controllable platform-based system that uses aerial manipulation rather than direct water contact. This substitution reduces the harmful mechanical impacts on aquatic ecosystems while maintaining sediment removal effectiveness.
4Productivity
If specialized dredgers with trained companies are deployed, then sediment management can be performed, but operational costs become very high
Solution Approach 1:
The platform is designed as a multi-functional unit that can perform various dredging operations and be deployed in different water bodies. This universality reduces the need for specialized equipment for each operation, thereby lowering operational costs while maintaining sediment management capability.
