Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in making high-quality electronic photographs of handwritten notes accessible, as existing methods are cumbersome and inefficient.
Innovation Solution
A portable computing device with a rotatable lid and camera system that captures multiple photographs from different angles while the lid closes, using high-dynamic range imaging to generate an enhanced image of handwritten text or drawings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple photographs are captured from different angles while the lid closes, then the image quality and completeness of handwritten content is improved, but the complexity of the device and processing requirements increase
Solution Approach 1:
The system dynamically captures multiple photographs at different angles as the lid closes, using the natural rotational movement of the device. The processor dynamically determines when to capture images based on detected rotation, and dynamically generates a composite image from multiple captures. This dynamic approach allows high-quality imaging without requiring complex fixed-position imaging mechanisms.
2Measurement precision
If high-dynamic range imaging is used to generate enhanced images, then the quality and accuracy of digitized handwritten content is improved, but the processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by capturing multiple photographs during the natural lid-closing motion before the user needs the digitized content. The high-dynamic range imaging and composite image generation are initiated automatically as part of the capture process, completing the enhancement before the user requests the final image. This preliminary processing eliminates waiting time for the user.
3Ease of operation
If the camera captures photographs during lid rotation, then the ease of operation is improved, but the reliability of capturing complete content may worsen due to motion blur or incomplete frames
Solution Approach 1:
The system maintains continuous useful action by capturing multiple photographs throughout the entire lid-closing rotation, ensuring that the handwritten content is captured from multiple angles and positions. Rather than relying on a single static capture, the continuous capture sequence ensures complete content acquisition even during motion, with the processor then combining these continuous captures into a reliable composite image.

AI summary
A portable computing device may include a lid and a base. The lid may include a display and a camera on a front side of the lid. The base may include a keyboard on a top side of the base and a processor inside the base. The processor may be coupled to the display, the camera, and the keyboard. The processor may be configured to determine that the front side of the lid is rotating toward the top side of the base, and instruct the camera to capture at least a first photograph and a second photograph based on the determination that the front side of the lid is rotating toward the top side of the base.
