Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable computing devices face issues where actuating the push-to-open mechanism and power switch simultaneously can cause unintended power down of displays, disrupting user interactions, especially when transitioning from an external to internal screens.
Innovation Solution
A foldable computing device with a push-to-open mechanism and power switch actuated by a single actuator, featuring a detection mechanism that detects the displaced position of the actuator to predict user intentions and control the operating state, suppressing power switch events that would power down displays during intended transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the push-to-open mechanism and power switch are actuated by a single actuator, then the ease of operation is improved, but unintended power down of displays occurs disrupting user interactions
Solution Approach 1:
The system uses a detection mechanism to monitor the position of the actuator and provides feedback to the processor. The processor analyzes this feedback to determine whether the user intends to open the device or power down the display, enabling intelligent differentiation between these two actions that both involve actuator movement.
Solution Approach 2:
The detection mechanism detects the displaced position of the actuator before the power switch event is fully executed. By detecting the position in advance, the system can predict user intention and prevent unintended power down events before they occur, allowing seamless transitions between screen configurations.
2Reliability
If the power switch event is suppressed to prevent unintended power down, then the reliability is improved, but the device complexity increases due to detection mechanism and control logic
Solution Approach 1:
The single actuator serves multiple functions: it can push to open the device by actuating the push-to-open mechanism, and it can also actuate the power switch for power down events. This multi-functionality reduces the need for separate physical components while the detection mechanism and control logic differentiate between these functions through position analysis.
Solution Approach 2:
The detection mechanism acts as an intermediary between the actuator and the power switch event. It monitors the actuator position and provides information to the processor, which then decides whether to allow or suppress the power switch event. This intermediary layer enables intelligent control without requiring complex additional hardware.
3Productivity
If the detection mechanism monitors actuator position to predict user intention, then the productivity is improved by enabling seamless transitions, but the device complexity increases
Solution Approach 1:
The detection mechanism continuously monitors the actuator position and provides real-time feedback to the processor. This feedback loop enables the system to predict user intention dynamically, allowing seamless transitions between external and internal displays without interrupting the user workflow.
Solution Approach 2:
By detecting the actuator position in advance of the power switch event, the system can predict user intention before the action is completed. This preliminary detection enables proactive control decisions that maintain productivity and enable seamless transitions.

AI summary
A foldable computing device comprises a first frame rotatably coupled to a second frame. The second frame comprises a push-to-open mechanism comprising an actuator and a power switch located for actuation by the actuator. A detection mechanism detects a displaced position of the actuator that corresponds to releasing the foldable computing device from a closed configuration. Actuation of the power switch is detected and used with detection of the displaced position of the actuator to control an operating state of the computing device.
