Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional biodiversity solutions are used, then biodiversity improvement is attempted, but efficiency and accessibility are not optimal
Solution Approach 1:
The invention changes the physical and chemical parameters of the structure by using additive manufacturing to create specific porosity, surface area, and material composition. The concrete mixture includes expandable agents, fertilizers, and pH-adjusting substances that transform the structure's properties over time, creating optimal conditions for biodiversity improvement while ensuring structural reliability
Solution Approach 2:
The invention uses composite materials combining concrete with organic fertilizers, expandable agents, and pH-adjusting substances. This composite approach creates a multi-functional structure that provides both structural stability and biological enhancement, resolving the contradiction between efficiency and reliability in biodiversity solutions
2Ease of manufacture
If additive manufacturing is used for the structure, then manufacturability and sustainability are improved, but manufacturing complexity increases
Solution Approach 1:
The invention segments the manufacturing process into distinct phases: preparing the additive mixture with specific components, printing the structure layer by layer, and allowing in-situ expansion and chemical reactions. This segmentation simplifies each individual step while achieving complex overall functionality, improving ease of manufacture without overwhelming complexity
Solution Approach 2:
The structure performs self-service functions through in-situ expansion of embedded agents, automatic pH adjustment, and fertilizer release. These self-service capabilities reduce the need for post-manufacturing interventions and simplify the overall manufacturing process, as the structure completes its own preparation and activation
3Ease of operation
If magnets are used for attachment, then attachment ease is improved, but magnetic force reliability in underwater conditions may be compromised
Solution Approach 1:
The invention uses curved or rounded magnetic attachment surfaces that better conform to the cylindrical sheet pile structures. This curvature improves contact area and magnetic coupling, enhancing attachment reliability in underwater conditions while maintaining ease of operation through simple magnetic attraction
Solution Approach 2:
The magnetic attachment components use composite materials with high magnetic permeability and corrosion resistance. This composite approach maintains strong magnetic forces in the corrosive underwater environment while preserving the ease of magnetic attachment operation
4Duration of action of stationary object
If the structure is made entirely of stone material, then durability and sustainability are improved, but manufacturing flexibility decreases
Solution Approach 1:
The invention changes the parameters of stone material (concrete) by incorporating expandable agents, fertilizers, and pH-adjusting substances. These parameter changes allow the stone material to exhibit time-dependent properties such as expansion, nutrient release, and pH adjustment, maintaining durability while adding manufacturing flexibility and functional versatility
Solution Approach 2:
The invention applies different local qualities within the stone material structure, with varying concentrations of expandable agents, fertilizers, and pH-adjusting substances in different regions. This local quality variation allows tailored functionality in different parts of the structure while maintaining overall durability and stone material composition
