Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices with flexible displays face challenges in achieving a compact geometric form factor while providing a larger display surface area, and manual transitions between display positions can be cumbersome and delay usability.
Innovation Solution
An electronic device with a single housing incorporating a flexible display that slides and wraps around the housing, using a translation mechanism to automatically adjust the display position based on content presentation, allowing seamless transitions between extended, retracted, and peek positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a sliding mechanism with two device housings is used to achieve a larger display surface area, then the display area is improved, but the device becomes bulky when closed due to the requirement of two housings
Solution Approach 1:
The flexible display is nested within a single device housing, allowing it to be concealed when not in use and deployed when needed. This eliminates the need for a second housing while providing a large display area, as the display can be stored inside the housing and extended outward when required.
Solution Approach 2:
The flexible display transitions from a static, fixed-position display to a dynamic, movable display that can be extended and retracted. This dynamic capability allows the display to adapt its position and size based on usage needs, achieving a large display area when opened while maintaining a compact form factor when closed.
2Device complexity
If manual user intervention is required for display position changes, then device complexity is reduced, but usability is delayed due to the need for manual adjustments
Solution Approach 1:
The system automatically detects the operating context and adjusts the flexible display position without requiring manual user intervention. The processor monitors usage patterns and contextual information, then autonomously controls the translation mechanism to optimize display positioning, making the device self-adjusting and improving ease of operation.
Solution Approach 2:
The system implements feedback by continuously monitoring operating context and usage patterns, then using this information to automatically adjust the display position. The processor receives feedback from sensors and software about current usage conditions, processes this information, and translates the flexible display accordingly, creating a closed-loop control system that optimizes usability.
3Ease of operation
If the flexible display translates automatically based on content presentation context, then ease of operation is improved, but device complexity increases due to the translation mechanism and context detection system
Solution Approach 1:
The processor performs multiple functions: it manages the translation mechanism, detects operating context, analyzes usage patterns, and controls display positioning. By consolidating these diverse functions into a single processing unit, the system achieves automatic display adjustment without proportionally increasing overall device complexity, as the processor leverages its existing computational capabilities across multiple domains.
Solution Approach 2:
The system merges the translation mechanism, context detection sensors, and control logic into an integrated subsystem. The translation mechanism is combined with the display assembly, the context detection is integrated into the existing processor framework, and the control algorithms are unified within the software architecture, reducing the need for separate dedicated components and minimizing overall complexity.

AI summary
A method in an electronic device identifies an operating context of the electronic device. The method determines a content presentation size of content corresponding to the operating context. The method then translates a blade assembly carrying a blade and flexible display that is slidably coupled to a device housing, as well as movable between an extended position, a retracted position, and optionally a peek position, to a position accommodating the content presentation size. Thereafter, one or more processors of the electronic device can present the content on the flexible display.
