Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connectors are used for electric connections between building blocks, then electric connections can be established, but the device complexity increases and water-resistance is compromised
Solution Approach 1:
The patent replaces the mechanical connector system with a magnetic field-based wireless power transmission system. The master module contains a power transmission unit that generates a magnetic field to wirelessly transmit power to slave modules, eliminating the need for physical electric connectors and thereby improving water-resistance while reducing structural complexity
Solution Approach 2:
The patent introduces a magnetic field as an intermediary medium to transfer power between modules. The power transmission unit generates a magnetic field that acts as a mediator to carry energy from the master module to slave modules without requiring direct physical contact, thus resolving the contradiction between connection reliability and structural complexity
2Ease of operation
If additional transmission lines or connectors are added for electric connections, then power and signals can be transmitted, but the ease of operation decreases
Solution Approach 1:
The patent replaces manual connector assembly with automatic magnetic field-based wireless power transmission. Users simply need to bring modules close together for the magnetic field to automatically establish power transmission, eliminating the need to manually connect transmission lines and significantly improving ease of operation
Solution Approach 2:
The system performs automatic power transmission establishment through the power transmission unit detecting and establishing magnetic field connections without user intervention. The modules self-configure their power transmission paths, eliminating the need for users to manually manage complex transmission line connections
3Adaptability or versatility
If traditional connectors are used for building blocks, then electric connections are established, but the adaptability to different age groups is limited
Solution Approach 1:
The patent replaces complex mechanical connector operations with simple magnetic field-based wireless power transmission. This simplification makes the building blocks accessible to children and non-experts who cannot handle complex connector assemblies, while still providing advanced functionality for adults, thereby greatly expanding adaptability across age groups
