Smart Pad Screen Seam Adjustment for Display Input Trade-offs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld computing devices with single touch screen displays face challenges in balancing display graphics and input areas due to limited screen space, leading to user frustration and productivity loss due to visual clutter and difficulty in interpreting complex interactions.
Innovation Solution
A dual multi-display handheld device that divides the screen into logical displays with adjustable aspect ratios, viewing angles, and image sizes, allowing for different configurations based on energy storage device parameters to optimize energy usage and user interface flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual keypad or user interface is superimposed on the display, then input functionality is provided, but the display space for graphics is reduced and visual clutter increases
Solution Approach 1:
The patent divides the single physical display into multiple logical displays (first logical display and second logical display) that can be independently configured. This segmentation allows different portions of the interface to be separated - graphics can occupy one logical display while input elements occupy another, eliminating the need to superimpose controls over content and resolving the conflict between input functionality and display space.
2Adaptability or versatility
If the screen is divided into logical displays with adjustable aspect ratios, then user interface flexibility is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic seam positioning that can be adjusted based on energy storage device parameters such as battery charge level. The seam between logical displays can move to different positions, allowing the system to adapt its configuration dynamically - for example, allocating more display real estate to content when battery is low and vice versa. This dynamic adaptation provides interface flexibility without requiring complex manual reconfiguration by the user.
Solution Approach 2:
The system automatically adjusts the logical display configuration based on monitored energy storage parameters without requiring user intervention. The seam position and logical display dimensions are self-adjusting based on system state, eliminating the need for complex user-facing configuration options while maintaining high adaptability to different operating conditions.
3Loss of energy
If energy conservation measures are implemented, then power usage is reduced, but display functionality and user experience may be compromised
Solution Approach 1:
The logical display configuration dynamically adapts to energy storage device parameters such as battery charge level. When energy is low, the system can adjust seam positions to optimize power consumption - for example, reducing the active area of high-power display regions or consolidating logical displays to minimize refresh requirements. When energy is abundant, the system can provide full functionality across all logical displays. This dynamic adaptation allows energy conservation without permanently compromising display functionality.

AI summary
A computational device divides, by a seam, a screen into first and second logical displays; in a first mode, moves the seam to a first position to provide logical displays having different selected aspect ratios, viewing angles, and/or a viewable image sizes and, in a second mode, moves the seam to a second different position to provide logical displays having still different selected aspect ratios, viewing angles, and/or a viewable image sizes.
