Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a three-dimensional net shaped body is used to control mechanical properties, then mechanical strength and stiffness are improved, but functional versatility beyond mechanical properties deteriorates
Solution Approach 1:
The patent applies multi-functionality by integrating mobile objects (such as micro-particles or droplets) within the three-dimensional net shaped body, enabling the structure to perform multiple functions including mechanical support, fluid transport, and responsive actuation. The mobile objects can be manipulated to provide additional functionalities beyond structural strength, such as controlling light transmission, heat transfer, or mechanical motion, thereby resolving the contradiction between mechanical strength and functional versatility.
Solution Approach 2:
The patent incorporates dynamic elements by allowing objects to move freely or be manipulated within the net shaped body. This dynamic capability enables the structure to change its properties or behavior in response to external stimuli (such as magnetic fields, electric fields, or fluid flow), transforming a static mechanical structure into a dynamic multi-functional system that can adapt its functionality while maintaining structural integrity.
2Adaptability or versatility
If mobile objects are added to enable novel functions, then functional versatility is improved, but device complexity deteriorates
Solution Approach 1:
The patent merges the mobile objects with the net shaped body structure, integrating multiple functionalities into a single unified system. Rather than adding separate complex mechanisms for each function, the mobile objects are incorporated directly within the net structure, allowing them to interact with the surrounding environment and each other to provide multiple functions (such as actuation, sensing, and transport) without requiring separate subsystems, thereby reducing overall device complexity while maintaining functional versatility.
3Adaptability or versatility
If objects move within partitioned spaces, then novel functions such as rotation and light transmittance control are achieved, but manufacturing precision requirements deteriorate
Solution Approach 1:
The patent segments the internal space of the net shaped body into multiple partitioned compartments, each containing mobile objects. This segmentation approach allows for simplified manufacturing of each individual compartment while achieving complex overall functionality through the collective behavior of mobile objects across multiple partitions. The partitioned structure provides defined pathways and constraints for object movement, enabling functions like rotation and light transmittance control without requiring extremely precise manufacturing of the entire structure at once.
