Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch screen operations are used for vehicle control, then vehicle function control capability is improved, but driver attention is diverted and driving safety deteriorates
Solution Approach 1:
The patent replaces the mechanical touch screen interaction system with a voice-based control system. The voice recognition device captures vocal commands from the driver, converts them to text, and executes corresponding vehicle control functions, eliminating the need for physical touch operations on the screen while maintaining full vehicle control capability.
Solution Approach 2:
The patent introduces voice recognition and text-to-speech conversion as intermediary processes between the driver and vehicle control functions. The voice recognition device acts as a mediator that translates spoken commands into control signals, while the text-to-speech system provides feedback, eliminating direct screen interaction and keeping the driver's attention on the road.
2Adaptability or versatility
If touch screen operations are used for vehicle control, then vehicle function control is enabled, but operation time is increased and efficiency deteriorates
Solution Approach 1:
The patent substitutes the time-consuming mechanical touch operations with instantaneous voice commands. The voice recognition system processes spoken commands in real-time, eliminating the sequential steps of screen positioning, finger movement, and touch execution, thereby dramatically reducing operation time while maintaining full vehicle function control.
Solution Approach 2:
The patent implements preliminary voice command recognition and interpretation before execution. The system continuously monitors and pre-processes voice inputs, ready to execute commands immediately upon recognition, eliminating the delay associated with manual screen navigation and touch operations.
3Reliability
If physical buttons on steering wheel are used for vehicle control, then driving safety is improved by keeping eyes on road, but device complexity and control precision deteriorate
Solution Approach 1:
The patent extracts the control interface from the physical steering wheel buttons and relocates it to the voice recognition system. This removes the need for multiple physical buttons and switches on the steering wheel, simplifying the overall control system architecture while maintaining driving safety through hands-free operation.
Solution Approach 2:
The patent implements a universal voice-based control interface that can execute multiple vehicle functions through a single modality. The voice recognition system serves as a multi-functional controller replacing numerous physical buttons, switches, and dials, thereby reducing device complexity while expanding control capabilities.
4Ease of operation
If touch screen operations are used for vehicle control, then vehicle function accessibility is improved, but driver workload and operational complexity increase
Solution Approach 1:
The patent replaces the complex mechanical touch screen interaction requiring precise finger positioning and screen navigation with simple voice commands. This substitution maintains full vehicle function accessibility while dramatically reducing operational complexity to basic spoken instructions.
Solution Approach 2:
The patent inverts the traditional control paradigm by replacing manual input operations with natural speech output. Instead of requiring the driver to physically navigate and select functions on the screen, the driver simply speaks the desired action, and the system interprets and executes it, reversing the complexity burden from the driver to the automated system.
