Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If power line communication technology is used for bicycle component communication, then electrical wiring is simplified and existing power lines can be utilized, but communication speed is limited and cannot handle large volumes of data such as video data
Solution Approach 1:
The communication system is segmented into two distinct transmission paths: a first transmission path for high-speed data communication and a second transmission path for power supply and control signals. This segmentation allows each path to be optimized for its specific function, resolving the contradiction between wiring simplicity and communication speed.
Solution Approach 2:
An optical communication unit serves as an intermediary device that bridges the gap between the existing power line infrastructure and the need for high-speed data transmission. The optical communication unit converts electrical signals to optical signals for high-speed transmission while maintaining compatibility with the existing power line system.
2Speed
If optical communication units are added to achieve high-speed communication, then communication speed and data transfer capability are improved, but device complexity increases
Solution Approach 1:
The optical communication unit and power line communication unit are merged into a single integrated communication device. This combination allows both high-speed optical communication and low-speed power line communication to coexist within the same component, reducing overall system complexity while maintaining high-speed capabilities.
Solution Approach 2:
The communication device is designed with multi-functionality, serving both as a power line communication interface and an optical communication interface. This universal design allows a single device to handle both power supply/control signals and high-speed data transmission, reducing the number of separate components needed.
3Productivity
If a dual transmission path system is implemented, then high-speed communication of large data volumes is enabled, but the communication system becomes more complex with multiple transmission paths
Solution Approach 1:
The communication system dynamically selects and switches between the first transmission path (optical) and second transmission path (power line) based on the type of data being transmitted. Control signals route small control data through the power line path while large multimedia data flows through the optical path, optimizing performance while managing complexity through intelligent dynamic routing.
