Inferred Undocking for Hybrid Tablet Computers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid tablet computers require explicit undocking actions, which are not intuitive and may not align with natural user interactions, limiting the ease of transitioning between tablet and laptop modes.
Innovation Solution
Implementing an inferred undocking system that detects non-explicit user gestures, such as gripping and pressure actions on the touchscreen and trackpad, to automatically initiate the undocking process, allowing the tablet to switch from cooperative to independent mode without explicit user commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If explicit undocking actions (buttons, icons, gestures) are required, then the undocking function is reliable and controllable, but the ease of operation deteriorates because the process is not intuitive and requires learning
Solution Approach 1:
The system automatically detects undocking intent through sensors and infers user action without requiring explicit commands. The hybrid tablet self-determines when undocking is desired based on detected gestures or pressure changes, eliminating the need for users to learn specific undocking procedures.
Solution Approach 2:
The patent replaces explicit mechanical or software-based undocking controls (buttons, icons) with an inference system that uses sensor data to automatically determine undocking intent. This substitution transforms the interaction from deliberate control to automatic detection.
2Productivity
If explicit undocking commands are required, then the system maintains precise control over mode switching, but the productivity deteriorates due to additional time and steps required for mode transitions
Solution Approach 1:
The system continuously monitors sensor data and prepares for undocking in advance by detecting early signs of undocking intent (such as gripping gestures or pressure changes). This preliminary detection allows the system to initiate the undocking process sooner, reducing the overall transition time.
Solution Approach 2:
The automatic detection and inference system eliminates the need for users to spend time locating and executing explicit undocking commands. The system handles the mode transition initiation automatically based on detected user actions, thereby reducing the time required for mode switching.
3Ease of operation
If the hybrid tablet requires explicit undocking actions, then the reliability of mode switching is maintained, but the ease of manufacture deteriorates due to additional hardware or software components needed for explicit controls
Solution Approach 1:
The patent replaces the need for dedicated undocking control hardware (buttons, switches) or complex software interfaces with an inference system that utilizes existing sensors. This substitution simplifies manufacturing by repurposing existing components rather than adding new dedicated undocking controls.
Solution Approach 2:
The system uses existing sensors (touchscreen controllers, pressure sensors, motion detectors) for multiple purposes: both normal operation detection and undocking intent inference. This multi-functionality eliminates the need for separate dedicated undocking control components, simplifying manufacturing.
