Touch Panel Vibration Control for Image Processing Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing devices such as printers and scanners are vulnerable to external vibrations and shocks, which can disrupt their operation and lead to distorted images, and existing touch panel feedback methods may not provide effective tactile feedback in noisy environments.
Innovation Solution
An image processing device with a touch panel that includes a vibrator unit and a response controller to apply responsive vibration, which adjusts the vibration level based on the device's operating condition to avoid adverse effects on image processing, ensuring users receive tactile feedback without compromising device reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch panel applies responsive vibration at high level, then the tactile feedback effect is improved, but the image processing reliability deteriorates due to vibration-induced distortion
Solution Approach 1:
The patent applies dynamics by making the vibration level adjustable rather than fixed. The controller dynamically changes the vibration intensity based on the operational state of the image processing device, using high vibration levels when the device is idle and low vibration levels when the device is operating, thus resolving the contradiction between tactile feedback effectiveness and image processing reliability
Solution Approach 2:
The patent implements parameter changes by modifying the vibration parameter (intensity level) according to the operational context. The system transitions between different vibration intensity parameters depending on whether the image processing device is in a waiting state or an operating state, allowing optimal tactile feedback without compromising image quality during critical operations
2Ease of operation
If the touch panel applies vibration during image processing, then the operational feedback is improved, but the image quality deteriorates due to vibration-induced distortion
Solution Approach 1:
The system dynamically adjusts the vibration application based on real-time operational status. When the image processing device is actively processing images, the controller suppresses or reduces vibration output to prevent distortion, while enabling full vibration feedback during idle periods, thus maintaining both operational feedback quality and image processing precision
Solution Approach 2:
The controller proactively prevents vibration-induced image distortion by detecting the operational state beforehand and suppressing vibration output during critical image processing periods. This preliminary anti-action ensures that vibration feedback does not interfere with the precision requirements of image capture and processing operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows users to perceive tactile feedback from the touch panel while preventing excessive vibration from affecting the image processing device's operation, enhancing user experience without degrading image quality.

AI summary
A touch panel has a display region for an operation screen and senses an outer object touching the display region. A vibrator unit applies vibration to the display region. In response to the touch panel sensing the object, a response controller unit instructs the vibrator unit to apply to the display region vibration responsive to the object. The response controller unit checks whether an image processing unit is under waiting or operating condition at the time the touch panel senses the object, and when the image processing unit is under the operating condition, sets the responsive vibration to a level lower than when the image processing unit is under the waiting condition.
