Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surface-mounted electrical installation systems are used, then electrical functions can be provided on wall surfaces, but installation requires significant time and cost investment and requires qualified electricians
Solution Approach 1:
The electrical installation system is divided into modular components: a base module that attaches to the wall surface and multiple interchangeable expansion modules, each providing different electrical functions. This segmentation allows pre-fabricated modules to be quickly assembled on-site without requiring extensive electrical wiring work, reducing installation time while maintaining reliability through standardized connection interfaces
Solution Approach 2:
The base module and expansion modules are pre-assembled and pre-wired in a controlled manufacturing environment before delivery to the installation site. This preliminary action ensures proper electrical connections are already established, eliminating the need for on-site wiring work by qualified electricians and significantly reducing installation time while maintaining installation reliability
2Adaptability or versatility
If conventional electrical appliances are installed, then electrical functions are provided, but user flexibility in adapting or expanding functions is limited by existing wiring and wall conditions
Solution Approach 1:
The system employs dynamically reconfigurable module combinations where users can attach and detach different expansion modules based on their changing needs. The base module serves as a universal platform that can accommodate various expansion modules with different functions (power outlets, USB ports, data communication, etc.), allowing the installation to adapt to evolving user requirements without complex rewiring or structural modifications
Solution Approach 2:
The base module is designed as a universal platform with standardized interfaces that can work with multiple types of expansion modules. This universality allows a single base installation to support diverse electrical functions through module substitution, greatly enhancing adaptability while keeping the base installation simple and reducing overall system complexity
3Ease of operation
If conventional electrical installation systems are used, then wall surface electrical functions are provided, but the installation process is complex and requires qualified electricians
Solution Approach 1:
The complex electrical wiring and power distribution system is extracted and pre-integrated into the base module during manufacturing. The base module contains all necessary electrical components, connection terminals, and wiring harnesses pre-assembled and tested. This extraction removes the complexity of on-site electrical work, allowing end-users to perform simple mechanical attachment operations without requiring qualified electricians
