Rollable Display Blade Assembly Translation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable communication devices with sliding or translating form factors face challenges in achieving a compact geometric form factor while providing a larger display surface area, as they tend to be bulky in the closed position due to the requirement of two separate housings.
Innovation Solution
A rollable display device with a blade assembly that slides relative to the device housing, automatically extending or retracting based on contextual sensors detecting user interaction or notification opportunities, optimizing power consumption and display usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a sliding or translating form factor with two separate housings is used, then a larger display surface area can be achieved, but the device becomes bulky in the closed position
Solution Approach 1:
The patent merges the display and blade assembly into a single integrated unit that can be reconfigured. The display is coupled to the blade assembly such that it can extend beyond the housing when needed and be contained within the housing when not in use, eliminating the need for a second separate housing while still providing expandable display area.
Solution Approach 2:
The patent implements a dynamic configuration system where the display and blade assembly can transition between extended and retracted positions. The translation mechanism allows the blade assembly to move dynamically based on operational needs, enabling the device to adapt its form factor from compact to expanded state.
2Productivity
If the display is continuously extended for notification presentation, then user notification opportunities are captured, but power consumption increases
Solution Approach 1:
The patent implements periodic action by extending the display only when notification opportunities are detected and retracting it when not needed. The system monitors for user interactions and notification events, extending the display blade assembly periodically to present notifications, thereby capturing productivity opportunities while minimizing power consumption by keeping the display retracted during idle periods.
3Productivity
If the display is frequently extended and retracted, then notification opportunities are captured, but the display may suffer from unnecessary strain or damage
Solution Approach 1:
The patent implements feedback mechanisms through sensors that detect contextual states such as user pickup, device orientation, and notification events. The system uses this feedback to intelligently determine when to extend or retract the display blade assembly, extending it only when notification opportunities are detected and retracting it when not needed, thereby capturing productivity opportunities while minimizing unnecessary mechanical movements that could cause strain or damage.
4Use of energy by moving object
If contextual sensors are used to detect user interaction, then power consumption is optimized, but device complexity increases
Solution Approach 1:
The patent implements self-service by using sensors to automatically detect contextual states and trigger appropriate display actions without requiring manual user intervention. The system monitors for user pickup, device orientation, and notification events, automatically extending or retracting the display blade assembly based on detected conditions, thereby optimizing power consumption through automated decision-making that reduces the need for complex control interfaces.

AI summary
An electronic device, method, and computer program product enable a space saving rollable display device to extend automatically in a power efficient manner. While a blade assembly is in a retracted position, a controller of the electronic device determines whether a user notification opportunity exists based on a transition between contextual states of one of stationary and changing from unattended to attended by the user; and stowed on-body of the user changing to held by the user. In response, the controller actuates a translation mechanism to slide a blade assembly, which includes a blade and flexible display, relative to a device housing of an electronic device from a retracted position to at least a partially extended position. The actuation prepares the flexible display to present user notification(s) and generates a physical indication to a user that the user notification(s) is available to be presented when the flexible display is active.
