Multi-Display Handheld Device for Simultaneous Application Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld devices are limited in their ability to operate multiple applications simultaneously due to a lack of screen space and design constraints, which restricts their functionality and prevents them from utilizing enhanced display resolution or larger screen sizes.
Innovation Solution
A handheld device with multiple display units and a processor configuration that allows for simultaneous operation of multiple applications across these displays without increasing the device's footprint, featuring a design that can switch between a compact and expanded configuration to optimize screen usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display units are added to enable simultaneous operation of multiple applications, then the display capability and functionality are improved, but the device size and complexity increase
Solution Approach 1:
The display system is segmented into multiple independent display units (first display unit and second display unit), each capable of displaying different applications simultaneously. This segmentation allows the device to handle multiple applications concurrently while maintaining a manageable structure through modular design
Solution Approach 2:
The processor is designed to universally control multiple display units and run multiple applications simultaneously, making the system multi-functional. The same processor handles both the first and second display units, and can execute various types of applications (telephonic communication, internet browsing, video playback, etc.) across different displays
2Area of stationary object
If the device size is increased to provide larger screen space for multiple applications, then the display area is improved, but the portability and compactness deteriorate
Solution Approach 1:
The second display unit is positioned in a different spatial dimension relative to the first display unit, specifically on an opposite face of the device. This dimensional arrangement allows both displays to be visible from the same external viewing location when the device is in its expanded configuration, effectively increasing display area without proportionally increasing device volume
3Ease of operation
If multiple display units are made visible from the same viewing location, then the usability and accessibility are improved, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The device structure is made dynamic through an expandable configuration mechanism that allows transition between compact and expanded states. In the expanded configuration, both display units are positioned to be visible from the same external viewing location, enhancing usability. The dynamic nature of the configuration allows the device to adapt between portability (compact mode) and usability (expanded mode)
Solution Approach 2:
The multiple display units are arranged in a nested-like configuration where the second display unit is positioned on the opposite face relative to the first display unit. This nested arrangement on opposite faces allows both displays to be accessible from the front when expanded, while maintaining a compact form factor when collapsed, simplifying the manufacturing approach compared to completely separate display assemblies
Data Source
AI summary
A handheld device includes a plurality of display units and at least one processor coupled to the plurality of display units. The processor is configured to generate output at least a portion of which is displayed on at least one of the display units. At least two of the display units are configured to present data associated with different applications running on the processor, the applications operating simultaneously and independently of one another.
