Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electronic communication devices with sliding displays face challenges in accurately capturing and storing image orientation information, as existing technologies do not effectively integrate display position and device orientation sensors to determine the correct image orientation for image files.
Innovation Solution
A handheld electronic device with a movable display screen and integrated sensors, including an orientation sensor and position sensors, that determines image orientation by combining display screen position information and device orientation data to store image data with orientation information, allowing for correct display orientation in landscape or portrait modes based on the device's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display assembly is made movable between retracted and extended positions, then the device provides enhanced display flexibility and user experience, but the complexity of determining accurate image orientation increases
Solution Approach 1:
The patent combines multiple sensors (orientation sensor and display position sensor) into an integrated sensing system that simultaneously captures both device orientation and display position information. The processor merges these data streams to automatically determine correct image orientation, resolving the complexity by creating a unified orientation determination mechanism rather than separate systems.
Solution Approach 2:
The system implements feedback by continuously monitoring display position through position sensors and using this information to dynamically adjust image orientation. The processor receives real-time position feedback and automatically corrects image orientation based on the detected display state, creating a self-regulating system that adapts to changing display configurations.
2Measurement precision
If multiple sensors are integrated to determine image orientation accurately, then image orientation accuracy is improved, but device complexity increases
Solution Approach 1:
The orientation sensor serves multiple functions: it detects both the overall device orientation and, in combination with display position data, the effective image display orientation. This multi-functionality allows the system to use a single sensor for multiple measurement purposes, improving accuracy without proportionally increasing complexity.
Solution Approach 2:
The processor acts as an intermediary that synthesizes information from multiple sensors (orientation sensor and display position sensor) to produce the final image orientation determination. Rather than requiring direct complex integration of sensors, the processor mediates between the simple outputs of individual sensors to achieve accurate composite orientation measurement.
3Ease of operation
If the device automatically determines image orientation using integrated sensors, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The device performs self-service by automatically determining and adjusting image orientation without user intervention. The integrated sensors and processor work autonomously to detect display position and device orientation, then automatically correct image orientation, eliminating the need for manual user configuration while the system handles the complexity internally.

AI summary
A handheld electronic device having a movable display screen is used to capture image data. The movable display screen is movable between a first position and a second position, wherein in the first position a first portion of the display screen is hidden from view and a second portion of the display screen is viewable, and in the second position the first portion and the second portion of the display screen are viewable, the handheld electronic device having an image sensor, an orientation sensor for sensing an orientation of the handheld electronic device, and at least one position sensor for sensing a position of the display screen. Device orientation information is received from the orientation sensor, display screen position information is received from the position sensor and image data is received from the image sensor representing an image. An image orientation for the image is determined in dependence on both the display screen position information and the device orientation information.
