Solution Overview
Problem
Current electronic devices, such as notebooks and smartphones, often suffer from accidental touches on touchpads due to their proximity to keyboards, leading to inefficiencies and time wastage as users correct mistakes.
Innovation Solution
An electronic device equipped with a synthetic aperture radar that senses the presence of a charged body near a second input device, such as a keyboard, to dynamically disable or enable a first input device, like a touchpad, preventing accidental interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the touch pad is disposed under the keyboard to provide multiple input interfaces, then the functionality and versatility of the electronic device is improved, but accidental touches on the touch pad increase leading to reduced operational efficiency
Solution Approach 1:
The patent applies dynamics by making the touch pad's operational state changeable through a switching mechanism controlled by a sensor. The touch pad can dynamically transition between enabled and disabled states based on detected user actions, allowing the system to adapt its configuration in real-time to prevent accidental touches while maintaining functionality when needed.
Solution Approach 2:
The patent implements feedback through a sensor that detects user actions (such as keyboard input) and provides this information to a controller, which then adjusts the touch pad's state accordingly. This closed-loop feedback mechanism allows the system to respond to user behavior patterns and automatically disable the touch pad when accidental touches are likely, thereby maintaining high productivity.
2Ease of operation
If the touch pad remains always enabled to ensure continuous usability, then the ease of operation is improved, but accidental inputs increase causing time loss for corrections
Solution Approach 1:
The touch pad's enabled/disabled state is made dynamic rather than static. The switching mechanism allows the touch pad to be automatically disabled when the sensor detects conditions that predispose to accidental touches (such as heavy keyboard usage), and re-enabled when appropriate. This dynamic adjustment eliminates time loss from corrections while preserving ease of operation when needed.
Solution Approach 2:
The system applies preliminary anti-action by proactively disabling the touch pad before accidental touches can occur. The sensor detects precursor conditions (like intensive keyboard input) and triggers the switching mechanism to disable the touch pad in advance, preventing the harmful effect of accidental inputs rather than reacting after they occur. This eliminates the need for time-consuming corrections.
3Productivity
If the touch pad is disabled to prevent accidental touches, then the productivity is improved, but the ease of operation deteriorates as users cannot accidentally access features
Solution Approach 1:
The feedback mechanism ensures that the touch pad is disabled only when necessary, based on real-time detection of user actions. When the sensor detects that the user is not engaged in activities that predispose to accidental touches (such as light or no keyboard input), the touch pad is automatically re-enabled. This maintains ease of operation for legitimate uses while preserving productivity by preventing accidental inputs during focused work periods.
Solution Approach 2:
The touch pad's operational state is dynamically adjusted based on detected user behavior patterns. The system transitions between disabled and enabled states smoothly and automatically, ensuring that the touch pad is accessible when the user intends to use it (maintaining ease of operation) while preventing accidental touches during periods when productivity is prioritized. This dynamic flexibility resolves the contradiction between productivity and ease of operation.

AI summary
An electronic device for preventing an accidental touch and an operating method thereof are disclosed, where the electronic device includes a first input device, a second input device, synthetic aperture radar and a main system. The synthetic aperture radar can sense whether a charged body is positioned near the second input device. When the charged body is positioned near the second input device, a voltage state of the synthetic aperture radar is pulled to a first logic level. When the voltage state of the synthetic aperture radar is in the first logic level, the main system disables the first input device.
