Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If existing educational robots use fixed complex structures, then structural stability is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The robot is divided into modular components including a base module with chassis and power system, functional modules (sensors, actuators, processors) that can be independently attached and detached, and a hierarchical structure allowing students to assemble/disassemble specific modules without affecting the entire system, thereby maintaining structural stability while improving ease of assembly
2Reliability
If existing educational robots use proprietary systems, then system reliability is improved, but adaptability deteriorates
Solution Approach 1:
The robot employs universal interfaces and protocols including standard electrical connectors, common communication protocols (I2C, SPI, UART), and open-source software platforms (Arduino, Raspberry Pi) that enable the same hardware base to support multiple programming languages and educational curricula, achieving both reliability through tested components and adaptability through universal compatibility
3Adaptability or versatility
If existing educational robots integrate advanced technologies, then technological currency is improved, but device complexity deteriorates
Solution Approach 1:
Advanced technological components such as computer vision cameras, LIDAR sensors, and autonomous navigation processors are segregated into separate optional modules rather than integrated into the core system, allowing schools to selectively add only the technological components needed for their curriculum while keeping the base system simple and manageable
Solution Approach 2:
Standardized intermediary interfaces and adapter boards are provided that simplify connections between advanced components and the base system, using universal communication protocols and standardized mounting mechanisms that reduce the complexity of integrating sophisticated technologies while maintaining ease of assembly and disassembly
