Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vibration patterns are used in portable terminals, then the haptic function is provided, but the vibration patterns are not adequate enough to satisfy user's various interests
Solution Approach 1:
The patent applies dynamics by making the vibration pattern adaptive and changeable based on user activity. The system transitions from static, pre-defined vibration patterns to dynamic, real-time generated patterns that respond to user movements and interactions, thereby increasing versatility without requiring complex hardware modifications
Solution Approach 2:
The patent changes physical parameters of the vibration output by transforming movement data into haptic feedback parameters. By converting motion sensors data into varied vibration characteristics (frequency, amplitude, duration), the system achieves diverse vibration patterns from a single vibration motor, resolving the contradiction between pattern variety and device complexity
2Adaptability or versatility
If haptic data is generated from user movement, then user-specific haptic experience is provided, but additional sensors and processing are required
Solution Approach 1:
The patent applies universality by making the movement detection system serve multiple functions: it not only detects user activity for haptic generation but also serves as input for other terminal functions. The same motion sensors and processing units are utilized for both haptic feedback generation and general interaction control, reducing the need for additional dedicated components
Solution Approach 2:
The system applies self-service by using the terminal's existing movement detection capabilities to generate haptic feedback automatically. The terminal's own motion sensors and processing units are utilized to create user-specific haptic experiences without requiring external equipment or additional specialized components, thereby achieving personalization without proportionally increasing device complexity
3Adaptability or versatility
If vibration corresponds to haptic data is generated, then tactile sense stimulation is achieved, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by generating vibrations in response to discrete movement events rather than continuous operation. The vibration motor operates periodically, triggered by detected user activities, rather than running continuously, thereby reducing energy consumption while maintaining effective tactile stimulation during relevant moments
