Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wave attenuation structures, such as wave fences, degrade quickly due to high wave energy and require frequent replacement or repair, and are not environmentally friendly.
Innovation Solution
Construction units made of cementitious materials, particularly calcium carbonate-based materials, with a unitary design and angled openings in rectangular extensions, providing stability and resistance to wave action without fasteners, allowing for eco-friendly and long-lasting wave attenuation structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional wave fences made from wood, bamboo, and degradable substances are used, then environmental friendliness is improved, but durability and resistance to wave energy deteriorate
Solution Approach 1:
The material composition is changed from degradable organic materials (wood, bamboo) to durable cementitious materials while maintaining environmental compatibility. This parameter change in material properties enables the structure to withstand high wave energy and resist deterioration, thereby improving durability without completely sacrificing environmental friendliness.
Solution Approach 2:
The invention uses composite cementitious materials that combine multiple components to achieve both durability and environmental compatibility. The composite nature of the material provides enhanced strength and resistance to wave action while potentially incorporating eco-friendly additives or formulations.
2Ease of operation
If conventional wave fences use bolts and fasteners to attach sections, then ease of assembly is improved, but structural reliability deteriorates due to fastener failure under high wave energy
Solution Approach 1:
The invention merges multiple units into a single integrated monolithic structure. By eliminating the need for separate fasteners and connections, the structure avoids weak points where bolts and fasteners would fail under high wave energy, thereby improving structural reliability while maintaining ease of assembly through simple placement of pre-fabricated units.
Solution Approach 2:
The wave attenuation structure is divided into modular pre-fabricated units that can be individually manufactured and then assembled without fasteners. This segmentation allows for easy handling and placement while the monolithic design of each unit ensures structural integrity, resolving the contradiction between ease of assembly and structural reliability.
3Reliability
If wave attenuation structures are designed to be sturdy and resilient, then durability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The complex structural features, including anchoring elements and interlocking geometries, are incorporated into the units during pre-fabrication in a controlled manufacturing environment. This preliminary action allows for durable and resilient design without increasing on-site construction complexity, as the units are designed to be simple to place and assemble once manufactured.
