Touch Panel Indication Units for Position Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch panels in electronic devices lack the ability to indicate the touched position, making them less engaging for users.
Innovation Solution
An electronic device with a touch panel featuring a touch area divided into two meniscus-shaped regions with indicators that light up based on touch location, allowing the processing unit to determine the touch path and generate control signals to adjust parameters like brightness or volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional touch panels are used, then the device structure remains simple, but the user experience is poor because touch position cannot be indicated
Solution Approach 1:
The patent applies color changes by using indicators that light up in different colors or patterns to indicate the touched position on the touch panel. The indication unit changes its visual state based on the touch location, providing clear feedback to users about where they touched, thereby improving user experience without significantly complicating the device structure.
2Loss of information
If indication units are added to show touch position, then user feedback is improved, but the device complexity increases
Solution Approach 1:
The patent merges the indication function with the existing touch panel structure by integrating indication units into the touch panel assembly. This combining approach allows touch position feedback to be provided without adding completely separate components, thus reducing the increase in device complexity while still achieving effective information feedback about touch location.
3Ease of operation
If the touch panel provides visual feedback, then user interaction is enhanced, but the energy consumption increases
Solution Approach 1:
The patent implements periodic action by controlling the indication units to activate only when touch events occur, rather than continuously operating. The indicators light up briefly to show the touched position and then turn off, providing necessary visual feedback for user interaction while minimizing energy consumption by keeping the indication system dormant during non-touch periods.

AI summary
An electronic device includes a power management unit, a touch panel including a first touch area and a second touch area, a first indicator, a second indicator, and a processing unit. The first touch area and the second touch area are respectively located on two sides of the touch panel, and is used to produce touch signals in response to a user's touch. The position of the first indicator and a second indicator are respectively corresponding to the first touch area and the second touch area. The processing unit controls the power management unit to provide power to the first indicator only when determining the first touch area is touched by the user according to the touch signals received by it, and control the power management unit to provide power to the second indicator only when determining the second touch area is touched.
