Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple user functions are operated simultaneously on conventional portable terminals, then the functionality and versatility are improved, but the input operation complexity and difficulty increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single touch screen interface to handle multiple user functions simultaneously through different input signals. The terminal can process touch events, voice commands, and motion sensor signals through the same interface, allowing one component to serve multiple purposes and reducing the need for separate input mechanisms for each function.
Solution Approach 2:
The patent changes the parameters of input signals by recognizing different types of touch events (tap, long press, swipe), voice commands, and motion patterns. By varying the parameters of input detection, the system can distinguish between different user intentions and activate corresponding functions without increasing operational complexity.
2Device complexity
If conventional touch screen interfaces are used to operate multiple functions, then the device structure remains simple, but the task connection maintenance becomes difficult
Solution Approach 1:
The patent implements feedback mechanisms that provide visual, auditory, or haptic confirmation when functions are activated or switched. This feedback helps users maintain awareness of current tasks and connections between multiple functions, preventing information loss without requiring complex interface structures.
Solution Approach 2:
The system performs preliminary actions by pre-configuring different input signal types for specific functions and maintaining task state information in memory. When a user switches between functions, the system recalls previous task states, allowing seamless continuation without losing task connections.
3Adaptability or versatility
If frequent changes in display content occur to show different functions, then the adaptability to different tasks is improved, but the user's ability to maintain task connections deteriorates
Solution Approach 1:
The patent applies dynamics by making the display content adaptive and flexible. Instead of frequent abrupt changes, the system dynamically adjusts display content based on the current active function and user context, maintaining smooth transitions that help users track task connections while still providing access to multiple functions.
