Sliding Flexible Display Positioning for Compact Expandable Housings
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 can delay usability.
Innovation Solution
An electronic device with a single housing incorporating a flexible display that transitions between extended, retracted, and peek positions using a blade assembly and translation mechanism, automatically adjusting based on content presentation needs, and integrating sensors beneath the display for optimal real estate utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a larger display surface area is provided, then the display area is improved, but the device becomes bulkier and less compact
Solution Approach 1:
The display transitions from a static fixed-size configuration to a dynamic adjustable configuration. The display can expand to provide larger surface area when needed for content presentation, and contract to provide a compact form factor when not in use, thereby resolving the contradiction between display area and device volume.
Solution Approach 2:
The display utilizes three-dimensional space by extending beyond the device housing in certain directions. The display can protrude from the housing to provide additional display area without increasing the base footprint of the device, effectively using vertical and lateral dimensions to expand display area while maintaining compact horizontal dimensions.
2Adaptability or versatility
If manual transitions are implemented, then the display can be repositioned, but usability is delayed due to manual operation
Solution Approach 1:
The display positioning system operates autonomously without requiring manual user intervention. The system automatically detects when content presentation is needed and autonomously transitions the display to the appropriate position, eliminating the time loss associated with manual operation while maintaining the adaptability of display repositioning.
Solution Approach 2:
The system incorporates sensors and control mechanisms that detect user needs and automatically respond by adjusting display position. This feedback loop enables the display to self-adjust based on detected conditions, removing the delay caused by manual operation while preserving positioning flexibility.
3Area of stationary object
If sensors are integrated beneath the display, then real estate utilization is improved, but the display structure becomes more complex
Solution Approach 1:
The sensor array is merged with the display structure, with sensors integrated directly beneath the display substrate. This combining of functions allows sensors to occupy the same physical space as the display, maximizing real estate utilization without adding separate sensor housings or increasing overall device complexity.
Solution Approach 2:
The display structure serves multiple functions simultaneously: it provides visual output, houses integrated sensors for environmental or user detection, and acts as part of the mechanical transition mechanism. This multi-functionality allows the same structural elements to fulfill multiple roles, improving space utilization while avoiding the need for additional separate components that would increase complexity.
