Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connectors are provided to enable different host systems to access the same device simultaneously, then user diversity and accessibility are improved, but the complexity of determining connection states and managing transmission channels increases
Solution Approach 1:
The patent replaces complex mechanical or manual connection management with an automated electrical detection system. The transmission control device uses electrical connection detection to automatically identify which connectors are connected to host systems, substituting what would otherwise require manual tracking or complex mechanical switching mechanisms. This allows multiple connectors to be managed automatically through electrical signal detection.
Solution Approach 2:
The transmission control device performs self-detection of connection states through the channel-detecting device, which automatically monitors electrical connections without external intervention. The system self-manages the determination of connection states and automatically configures transmission channels based on detected connections, eliminating the need for manual configuration or complex external control mechanisms.
2Measurement precision
If connection state determination is based on electrical connection detection, then connection accuracy is improved, but the need for additional detection circuits and impedance management increases device complexity
Solution Approach 1:
The transmission control device serves multiple functions: it controls data transmission, detects connection states, and manages impedance levels. By integrating these functions into a single device, the patent avoids adding separate detection circuits that would increase complexity. The same control logic that manages transmission also performs detection, making the system multi-functional without requiring additional hardware components.
Solution Approach 2:
The patent combines the transmission control device with the channel-detecting device, merging connection detection functionality into the existing transmission control infrastructure. Rather than adding separate detection circuits, the detection capability is integrated into the control device that already manages data transmission, reducing overall system complexity while maintaining accurate connection state detection.
3Adaptability or versatility
If different operation functions are provided for different host systems, then user functionality and customization are improved, but the complexity of managing multiple communication channels increases
Solution Approach 1:
The patent implements dynamic channel management where the transmission control device automatically adjusts which communication channels are active based on detected connection states. When a connector is detected as connected, the corresponding transmission channel is activated; when disconnected, it is deactivated. This dynamic adaptation allows different operation functions for different host systems without requiring complex static configuration for each possible scenario.
Solution Approach 2:
The transmission control device is pre-configured with multiple communication channels corresponding to different connectors, but these channels remain inactive until needed. When a connection is detected, the corresponding channel is activated in advance of actual data transmission. This preliminary preparation allows quick switching between different host systems and operation functions without complex real-time configuration during operation.
