Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system provides multiple manipulation methods and functions, then the adaptability and versatility improve, but the device complexity increases
Solution Approach 1:
The touch screen is designed to serve multiple functions: displaying vehicle function screens, providing touch input capabilities, and acting as a graphical user interface for various manipulation methods (touch, gesture, voice). This multi-functional design allows the system to provide diverse manipulation methods without adding separate dedicated devices for each function, thereby improving versatility while controlling complexity.
Solution Approach 2:
The control unit acts as an intermediary that receives various types of input (touch inputs, gesture inputs, voice inputs) through the sensor unit and translates them into appropriate vehicle function manipulations. This intermediary layer abstracts the complexity of multiple manipulation methods from the user, allowing diverse input methods to interact with a unified system without requiring the user to understand the underlying complexity.
2Ease of operation
If the system uses sensor data, context data, and learning algorithms to determine user intention, then the ease of operation improves, but the device complexity and loss of information increase
Solution Approach 1:
The system pre-learns and stores context data related to user intentions and vehicle operation patterns in advance. This context data is prepared and available before actual user interaction occurs, allowing the control unit to quickly determine user intention during operation without requiring complex real-time analysis. The preliminary preparation of context data simplifies the real-time decision-making process while improving ease of operation.
Solution Approach 2:
The system continuously monitors sensor data (touch inputs, gesture inputs, voice inputs) and uses this feedback along with pre-stored context data to determine and adapt to user intention. This feedback mechanism allows the system to learn from user behavior patterns and improve its understanding of user intention over time, enhancing ease of operation while managing complexity through iterative learning rather than complex upfront design.
3Ease of operation
If the system outputs guide messages and screens for function manipulation, then the ease of operation improves, but the loss of information increases
Solution Approach 1:
The information output to the user is segmented into distinct components: visual screens displayed on the touch screen showing vehicle functions and manipulation options, and separate guide messages providing instructional information. This segmentation allows the system to present information in a structured, organized manner that is easier for users to process and understand, reducing information overload while improving ease of operation. The segmentation also helps manage information processing by handling different types of information through appropriate channels.
