Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bidirectional transmission path is used for all data transmission, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
The transmission path is segmented into unidirectional paths (first and second unidirectional transmission paths) and a bidirectional path (third unidirectional transmission path that can switch directions). This segmentation allows each path to be optimized for its specific function, reducing the need for all paths to be bidirectional while maintaining adaptability.
Solution Approach 2:
The third unidirectional transmission path is configured to switch transmission directions dynamically based on data transmission needs. This dynamic direction switching provides adaptability similar to a fully bidirectional system while allowing the other paths to remain simpler and less expensive to manufacture.
2Ease of manufacture
If fixed unidirectional transmission paths are used, then manufacturing cost is reduced, but data transmission efficiency decreases
Solution Approach 1:
The third unidirectional transmission path dynamically switches its transmission direction based on the data transmission direction determination unit's assessment of data volume ratios. This dynamic adjustment optimizes data transmission efficiency by directing traffic through the most appropriate path while keeping the physical infrastructure simpler and less expensive than fully bidirectional paths.
Solution Approach 2:
The system changes the operational parameter (transmission direction) of the third unidirectional path based on real-time data transmission requirements. By adjusting which direction the third path transmits data, the system optimizes overall transmission efficiency without requiring all paths to be complex bidirectional paths.
3Device complexity
If bidirectional transmission path direction is not dynamically adjusted, then device complexity is reduced, but data transmission efficiency decreases
Solution Approach 1:
The data transmission direction determination unit continuously monitors data volume ratios and provides feedback to control the transmission direction of the third unidirectional path. This feedback mechanism enables dynamic optimization of data transmission efficiency based on actual traffic patterns while keeping the control logic relatively simple and manageable.

AI summary
A data transmission system executes data transmission bidirectionally between two electronic devices. The data transmission system includes a first unidirectional transmission path, a second unidirectional transmission path, a bidirectional transmission path, and a transmission direction setting device. The first unidirectional transmission path allows data transmission in a first direction from one of the two electronic devices to another one of the two electronic devices. The second unidirectional transmission path allows data transmission between the two electronic devices in a second direction being opposite to the first direction. The bidirectional transmission path allows data transmission between the two electronic devices in a data transmission direction set to be either the first direction or the second direction. The transmission direction setting device sets the data transmission direction for the bidirectional transmission path.
