Dual-Side Touch Input Proximity Disable Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices with touch-sensitive displays often register inadvertent touch inputs due to proximity of objects, leading to incorrect interactions and increased power consumption.
Innovation Solution
A computing device with a housing featuring presence-sensitive input components on both sides and an object detection sensor that determines proximity to disable the appropriate input component to prevent inadvertent touches and reduce power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch-sensitive display is always enabled to receive user inputs, then ease of operation is improved, but inadvertent touch inputs from nearby objects increase
Solution Approach 1:
The proximity sensor performs preliminary detection of objects near the touch-sensitive display before inadvertent touches occur. When the sensor detects an object within a threshold distance, the system preemptively disables the touch-sensitive display, preventing inadvertent touch inputs before they can happen.
Solution Approach 2:
A proximity sensor is introduced as an intermediary component between the user environment and the touch-sensitive display. The sensor acts as a mediator that detects the presence of nearby objects and triggers the disabling of the touch display, thereby preventing harmful inadvertent inputs without requiring direct contact between the object and display.
2Object-affected harmful factors
If the touch-sensitive display is disabled to prevent inadvertent touches, then inadvertent touch inputs are reduced, but ease of operation deteriorates
Solution Approach 1:
The touch-sensitive display dynamically changes its operational state based on real-time proximity sensor data. The display transitions between enabled and disabled states according to the detected proximity of objects, allowing the system to adapt its behavior to current conditions rather than maintaining a fixed state.
Solution Approach 2:
The system implements a feedback loop where the proximity sensor continuously monitors the environment and provides information to the control logic, which then adjusts the touch-sensitive display state accordingly. This closed-loop control ensures the display is disabled only when necessary, maintaining ease of operation when no objects are nearby while preventing inadvertent inputs when objects are detected.
3Ease of operation
If the touch-sensitive display remains active to ensure user interaction, then ease of operation is maintained, but power consumption increases
Solution Approach 1:
The proximity sensor performs periodic detection cycles to monitor for nearby objects. Based on these periodic checks, the system intermittently enables or disables the touch-sensitive display, creating a periodic control pattern that reduces overall power consumption while maintaining input availability during active periods.
Solution Approach 2:
The system temporarily discards touch input functionality when objects are detected nearby, disabling the touch-sensitive display to conserve power. When objects move away and are no longer detected, the system recovers the touch input functionality by re-enabling the display, thus balancing power savings with operational needs.

AI summary
A computing device includes a housing that includes a front side and a back side. The computing device also includes a first presence-sensitive input component at the front side of the housing, a second presence-sensitive input component at the back side of the housing. The computing device includes at least one object detection sensor configured to generate sensor data. The computing device includes at least one processor, and a memory that includes instructions that cause the at least one processor to: determine whether an object is in the proximity of the computing device, responsive to determining that the object is in the proximity of the computing device, determine whether to disable a particular presence-sensitive input component located at a side of the housing opposite the at least one object detection sensor, and disable the particular presence-sensitive input component.
