Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touchscreen operations are used on wristwatch terminals, then input functionality is provided, but operation stability deteriorates due to being worn on the arm
Solution Approach 1:
The patent replaces manual touchscreen operations with automatic gesture recognition. Motion sensors detect arm movements and convert them into operational commands, eliminating the need for precise touchscreen interactions. This substitution of mechanical touchscreen operation with automated sensor-based gesture recognition resolves the contradiction by providing input functionality without requiring stable manual operation.
Solution Approach 2:
The wristwatch terminal automatically detects and interprets the user's intended operations through motion sensors that monitor arm gestures. The system serves itself by autonomously converting physical arm movements into digital commands without requiring manual touchscreen interaction. This self-service mechanism allows the device to maintain input functionality while overcoming the instability of manual touchscreen operations when worn on the arm.
2Ease of operation
If touchscreen operations are used on wristwatch terminals, then input functionality is provided, but both arms are required for operation
Solution Approach 1:
The patent replaces the need for touchscreen operations with gesture recognition technology. Motion sensors detect arm movements and automatically translate them into operational commands, eliminating the requirement for manual touchscreen interaction. This substitution simplifies the operation process from requiring both arms (one to wear, one to operate) to simply wearing the device and performing natural gestures.
Solution Approach 2:
The patent extracts the input operation function from the touchscreen interface and relocates it to the arm gestures themselves. By detecting motion patterns from the worn arm, the system derives operational commands directly from the user's natural movements, removing the need for a separate operation interface and reducing operational complexity.
3Adaptability or versatility
If conventional gesture recognition is used without arm state recognition, then basic gestures are recognized, but intuitive input based on purpose of use cannot be provided
Solution Approach 1:
The patent performs preliminary recognition of the arm's state and the user's purpose before executing gesture interpretation. By first determining whether the arm is at rest, moving, or performing a specific gesture, and understanding the contextual purpose, the system can then accurately interpret the user's intent. This preliminary state recognition enables more accurate and context-aware gesture processing.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors arm state, compares it against recognized gesture patterns, and adjusts interpretation based on the detected purpose. This closed-loop approach allows the system to refine its understanding of user intent by considering both the physical gesture and the contextual state, thereby providing more intuitive and accurate input recognition.
4Measurement precision
If motion sensor detection values are used without considering left or right arm wearing, then arm movement is detected, but accurate state recognition cannot be achieved
Solution Approach 1:
The patent applies asymmetry by recognizing that left and right arms have different movement characteristics and orientations. The system determines whether the device is worn on the left or right arm and adjusts the gesture recognition algorithms accordingly. This asymmetric adaptation allows the system to accurately interpret gestures regardless of which arm is being worn, compensating for the directional differences in arm movement and sensor orientation.
Solution Approach 2:
The patent dynamically changes detection parameters based on the identified wearing configuration. When the system determines the device is worn on a specific arm, it adjusts the threshold values, sensitivity settings, and gesture pattern definitions to match the characteristics of that arm's movement. This parameter adaptation ensures accurate state detection and gesture recognition across different wearing scenarios.
