Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an interface connector with identifier generation means is used to change the mode of pressing, then the mode switching capability is improved, but the configuration complexity and parts cost increase
Solution Approach 1:
The patent extracts the identifier generation means from the interface connector, leaving only simple connection terminals. The mode identification function is transferred to the controller which reads terminal connection states directly, eliminating the complex identifier generation hardware while maintaining mode switching capability.
Solution Approach 2:
The patent replaces the mechanical/electrical identifier generation system with a software-based detection system. The controller uses software to read the conductive state of connection terminals and determine the connected device type, substituting hardware complexity with software intelligence.
2Adaptability or versatility
If an interface connector with identifier generation means is used to change the mode of pressing, then the mode switching capability is improved, but the parts cost increases
Solution Approach 1:
The patent uses simple, inexpensive connection terminals without complex identifier generation components. These basic terminals are replaced or reconfigured as needed, providing a cost-effective solution compared to expensive connectors with integrated identifier generation hardware.
Solution Approach 2:
The patent replaces expensive hardware identifier generation systems with software-based detection, significantly reducing parts cost while maintaining the ability to identify and switch between different pressing modes.
3Device complexity
If a simple connection terminal configuration is used, then the device complexity is reduced, but the ability to accurately identify connected devices may be compromised
Solution Approach 1:
The patent adds a temporal dimension to device identification by detecting the sequence and timing of terminal connections. The controller analyzes which terminals are connected and in what combination, using this multi-dimensional information to accurately identify the connected device type despite the simplicity of the connection terminals themselves.
Solution Approach 2:
The system implements feedback through the controller which continuously monitors the connection terminal states and adjusts its mode selection based on the detected configuration. This closed-loop feedback ensures accurate device identification and appropriate mode switching even with simple connection terminals.
