Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If proximity input mode is provided with basic view function only, then device complexity is reduced, but user motivation and practicality are insufficient
Solution Approach 1:
The patent applies parameter changes by detecting frequency variations in proximity inputs to distinguish between different input types (e.g., hovering vs. touching). By analyzing frequency parameters, the system can identify whether the user intends to select, execute, or preview content without increasing physical device complexity, thereby enhancing user motivation while maintaining manageable system complexity.
Solution Approach 2:
The patent implements dynamics by transitioning between different operational modes (view function, selection function, execution function) based on detected input characteristics. The system dynamically adjusts its response to proximity inputs by changing functions according to the detected frequency patterns, making the interaction more intuitive and practical for users.
2Adaptability or versatility
If proximity input distinguishes only simple touch vs. hover gestures, then ease of operation is maintained, but functional versatility is limited
Solution Approach 1:
The patent utilizes parameter changes by detecting and analyzing frequency characteristics of proximity inputs. Different frequency ranges correspond to different input types (e.g., lower frequency for hovering, higher frequency for touching). This allows the system to distinguish multiple input types and execute corresponding functions without requiring complex hardware modifications, thereby enhancing adaptability while controlling processing complexity.
3Measurement precision
If proximity input mode is provided without frequency analysis, then device complexity is minimized, but input precision and functionality are insufficient
Solution Approach 1:
The patent applies parameter changes by analyzing frequency parameters of proximity inputs to accurately detect input types. By monitoring frequency variations, the system can precisely distinguish between different user intentions (selection, execution, preview) without requiring complex additional sensors or hardware, thereby improving measurement precision while maintaining reasonable device complexity.
