Mobile Device Hard Key Operation Time Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile devices with both hard keys and touch keys, operational errors occur due to the close proximity of these keys, leading to unintended activation of touch keys when using hard keys, particularly when the panel switch and hard switch are set together, causing malfunctions and operational errors.
Innovation Solution
Implementing a method where the operation of hard keys initiates a measurement of the hard key operation time, and touch key operations are invalidated until this time exceeds a predetermined restriction period, thereby prioritizing hard key operations and reducing operational errors by preventing false detection of touch key activations during hard key usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both panel switch and hard switch are set at the same time, then the mobile device can provide multiple input methods, but operational errors occur when hard switch is operated due to close proximity of the switches
Solution Approach 1:
The system preemptively disables touch key operations immediately when a hard key operation is detected, before any potential operational error can occur. This preliminary action prevents the user from accidentally activating touch keys during hard key operation, resolving the reliability issue while maintaining multiple input methods
Solution Approach 2:
The system applies a counter-action by invalidating touch key operations during the hard key operation period. This preliminary anti-action counteracts the potential harmful effect of accidental touch key activation, ensuring that only the intended hard key operation is executed
2Reliability
If touch key operations are invalidated during hard key operation, then operational errors are reduced, but the responsiveness of touch keys is temporarily reduced
Solution Approach 1:
The system applies periodic action by temporarily disabling touch keys only during the specific time window when hard key operation is detected, then restoring full touch key functionality afterward. This time-limited invalidation maintains reliability during critical periods while preserving normal responsiveness during non-conflict periods
Data Source
AI summary
A method and system of controlling key operations of a mobile device comprising one or more hard keys and one or more touch keys are disclosed. An operation of one or more hard keys is detected, and measuring an operation time is started in response to detecting the operation. Operations of one or more touch keys are invalidated until the operation time exceeds a certain period of time.
