Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If prior setting is required for imaging, then the device can provide basic vibration feedback, but it cannot handle changes in imaging situation effectively
Solution Approach 1:
The patent implements a feedback mechanism where the vibration control unit receives detection results from the autofocus processing (offset amounts and object image detection) and adjusts vibration patterns accordingly. This closed-loop feedback system enables the device to automatically adapt to changing imaging situations without requiring prior user settings, resolving the contradiction between adaptability and complexity by using intelligent feedback-based control.
Solution Approach 2:
The vibration pattern is made dynamic by continuously adjusting vibration parameters (amplitude, frequency, time) based on real-time autofocus detection results. This dynamic adaptation allows the device to respond to changing imaging conditions automatically, achieving high versatility without increasing operational complexity for the user.
2Loss of information
If a single vibration pattern is used, then the device is simple to control, but it cannot properly inform users of different imaging states
Solution Approach 1:
The patent applies different vibration patterns (different amplitudes, frequencies, and durations) to represent different imaging states (in-focus vs. out-of-focus conditions). By localizing specific vibration characteristics to specific imaging states, the system efficiently communicates detailed imaging information to the user without requiring a complex array of separate vibration mechanisms, thus resolving the contradiction between information transmission and control complexity.
Solution Approach 2:
The system changes vibration parameters (amplitude, frequency, time) based on autofocus detection results to convey different imaging states. This parameter-based differentiation allows rich information communication about imaging quality while maintaining simple unified vibration generation hardware, resolving the contradiction between information loss and device complexity.
3Speed
If continuous autofocus processing is performed, then the device can detect imaging states in real-time, but it requires complex prior settings to provide useful feedback
Solution Approach 1:
The vibration control unit automatically processes autofocus detection results and generates appropriate vibration feedback without requiring user configuration or prior settings. The system serves itself by intelligently interpreting offset amounts and object detection data to determine optimal vibration patterns, achieving both real-time detection speed and ease of operation through autonomous decision-making.
Solution Approach 2:
The system implements automatic feedback generation from continuous autofocus processing by using the detection results (offset amounts and object images) to directly control vibration patterns. This eliminates the need for manual settings while maintaining real-time responsiveness, resolving the contradiction between detection speed and ease of operation through intelligent automated feedback control.

AI summary
A vibration apparatus includes a vibrating unit, and a control unit configured to control vibration of the vibrating unit. The control unit changes a vibration pattern of the vibrating unit by controlling the vibrating unit so as to change at least one of a vibration amplitude, a vibration frequency, and a vibration time according to at least one of a detection result of an offset amount from an in-focus position and a detection result of a predetermined object image in a mode that continuously performs autofocus processing.
