Touch Panel Long-Touch Activation With Countdown Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Productivity in apparatuses equipped with touch panels is lowered due to erroneous button touches, leading to suspended operations.
Innovation Solution
A touch panel with functional buttons that require a long-touch activation and display a count-down signal notifying the activation time, preventing immediate activation upon touch and requiring precise finger movement to confirm the button selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel with multiple functional buttons is provided for operating an apparatus, then the ease of operation is improved, but the reliability deteriorates due to erroneous button touches that suspend apparatus operation
Solution Approach 1:
The system performs preliminary verification by detecting whether the touched object is a virtual button before executing the corresponding operation. This preliminary action prevents erroneous operations by validating the touch target, thereby resolving the contradiction between ease of operation and reliability
2Productivity
If immediate activation occurs upon button touch, then the productivity is improved through quick response, but the reliability deteriorates due to accidental touches triggering operations
Solution Approach 1:
The system applies preliminary anti-action by implementing a verification mechanism that prevents immediate activation. The control unit detects whether the touched object is a virtual button before activating the function, thereby preventing accidental operations while maintaining productivity through quick valid response
3Reliability
If a verification mechanism is added to detect touched objects, then the reliability is improved by preventing erroneous operations, but the device complexity increases
Solution Approach 1:
The control unit serves as an intermediary between the touch panel and the operation execution. It detects whether the touched object is a virtual button and mediates the activation process, thereby improving reliability without significantly increasing device complexity through a simple detection mechanism

AI summary
There is provided a touch panel that displays an image in which a plurality of functional buttons are arranged. The plurality of buttons include a long-touch button a function of which can be rendered active after the button is continuously touched for a predetermined time period, and attendant on the long-touch button, a count-down signal notifying a time period remaining before a timing at which the function can be rendered active is displayed.
