Touch Panel Interface with Delayed Start Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for operating electronic devices with touch panels lack mechanisms to prevent erroneous operations when controlling systems different from the device itself, such as wireless power transfer systems.
Innovation Solution
An electronic device with a touch panel that includes a display control unit to show user interfaces for starting and stopping wireless power transfer, a detection unit to detect user operations, and an instruction unit that delays transmitting start signals for the start function compared to stop signals, ensuring a longer time interval for user cancellation opportunities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electronic device transmits instruction signals immediately upon detecting user operations on the touch panel, then the responsiveness and productivity of the system is improved, but erroneous operations cannot be prevented when controlling external systems
Solution Approach 1:
The patent applies preliminary action by displaying a confirmation screen with a predetermined period before the instruction signal is actually transmitted. This allows the user to cancel the operation if it was unintentional, while still maintaining relatively quick response times. The system prepares the instruction in advance but delays final execution until confirmation is received or the timeout period expires.
2Reliability
If the electronic device displays a confirmation screen with a predetermined delay before transmitting start instruction signals, then erroneous operations are prevented, but the time required to initiate charging increases
Solution Approach 1:
The system displays a confirmation screen in advance but allows immediate cancellation by the user. This preliminary action provides error prevention while minimizing time loss since the user can quickly cancel if needed, and only experiences the delay if they intend to proceed with the operation.
Solution Approach 2:
Instead of requiring confirmation to proceed, the system inverts the logic by allowing the operation to be cancelled during the confirmation period. The default state becomes 'do not execute' rather than 'execute', and the user actively chooses to cancel if unintended, which reduces the perceived time penalty for error prevention.
3Reliability
If the electronic device applies different time intervals for start and stop operations, then erroneous start operations are prevented while maintaining quick stop response, but the system complexity increases
Solution Approach 1:
The patent applies local quality by making the time interval characteristic specific to each operation type (start vs. stop). The start operation uses a longer confirmation period with timeout, while the stop operation uses a shorter immediate response period. This differentiated approach provides operational accuracy without requiring complex overall system logic, as each operation type has its own simple, optimized handling rule.

AI summary
An electronic device according to an embodiment includes a display control unit, a detection unit, and an instruction unit. The display control unit displays a first user interface related to start of actuation of a target system, or a second user interface related to a function other than the start of actuation of the target system on a touch panel. The detection unit detects an operation of the first user interface or the second user interface. The instruction unit transmits an instruction signal according to the detected operation to the target system. A first time interval from an operation of the first user interface to a transmission of a first instruction signal for the start of actuation is longer than a second time interval from an operation of the second user interface to a transmission of a second instruction signal for the other function.
