Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel is used for input operations, then the device can detect touch positions, but it cannot provide tactile sensation feedback corresponding to the displayed image
Solution Approach 1:
The patent applies mechanical vibration by providing vibrating sections that physically vibrate the panel surface in response to user swiping operations. The vibration control section generates vibration signals that cause the panel to vibrate with specific frequencies and intensities, creating tactile sensations that correspond to the spatial frequency and texture of the displayed image, thereby compensating for the lack of inherent tactile feedback in touch panels.
Solution Approach 2:
The patent implements feedback by using the vibration control section to analyze the spatial frequency of the displayed image and the swiping speed, then generating appropriate vibration patterns as tactile feedback. This closed-loop feedback mechanism allows the system to respond to user input with sensory information that mirrors the visual content, enhancing the user's perceptual experience.
2Loss of information
If a vibrating section is added to provide tactile sensation, then tactile feedback is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the vibrating section to serve multiple functions: it can vibrate the panel surface for tactile feedback, and its vibration characteristics can be dynamically adjusted to represent different spatial frequencies and textures. The vibration control section integrates image analysis and vibration generation, allowing a single system to handle various types of tactile feedback requirements without requiring separate dedicated components for each function.
Solution Approach 2:
The patent uses parameter changes by dynamically adjusting the vibration frequency, amplitude, and pattern based on the spatial frequency of the displayed image and the user's swiping speed. The vibration control section modifies these parameters in real-time to match the visual content, allowing the same vibrating section to produce diverse tactile sensations without requiring multiple physical components.
3Device complexity
If vibration is varied by swiping speed only, then simple control is achieved, but spatial frequency information of the image is not utilized
Solution Approach 1:
The patent implements feedback by having the vibration control section continuously monitor both the user's swiping speed and the spatial frequency characteristics of the displayed image. This dual-parameter feedback mechanism allows the system to adjust vibration characteristics based on both the dynamics of user interaction and the static properties of the visual content, ensuring that tactile feedback accurately represents the image texture and detail.
Solution Approach 2:
The patent applies dynamics by making the vibration characteristics adaptive and responsive to changing conditions. The vibration frequency, amplitude, and pattern are not fixed but dynamically adjusted based on real-time analysis of the image spatial frequency and swiping speed, allowing the tactile feedback to evolve as the user interacts with different parts of the image at different speeds.

AI summary
The electronic device 100 includes a touch panel 102 to be touched by a user, a vibrating section 203 for vibrating the touch panel 102, a vibration control section 301 for controlling the vibration of the vibrating section 203, and a display section 101 for displaying an image. The vibration control section 301 changes the vibration of the vibrating section 203 in accordance with a speed at which the user performs a swiping operation on the touch panel 102 and a spatial frequency in a swiping direction of an image displayed at a position where the user is performing a swiping operation.
