Orthopedic Device Ordering App with Alignment Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for capturing images of limbs for custom orthopedic devices often result in image and limb misalignment, leading to poorly fitting braces due to the lack of feedback on camera orientation and angle, and require multiple devices and forms, complicating the ordering process.
Innovation Solution
A method and device using a portable device with an image sensor, gyroscope, and accelerometer to guide users in capturing aligned images of the limb by overlaying a depth of field guideline, allowing for accurate measurement and configuration of custom orthopedic devices through a single application, reducing human error and simplifying the ordering process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional camera is used to capture images of the limb, then the ordering process can be completed, but image and limb misalignment occurs leading to inaccurate portrayal of limb dimensions and proportions
Solution Approach 1:
The system provides real-time feedback through visual indicators (green/red alignment markers, crosshairs, and guidance overlays) that show the user whether the camera is properly aligned with the limb. This feedback loop allows the user to adjust the camera angle and position until the alignment criteria are met, ensuring accurate limb dimension capture without requiring professional photography skills.
Solution Approach 2:
The patent introduces an intermediary alignment system consisting of visual markers placed on the limb and corresponding digital overlays on the camera viewfinder. These intermediaries serve as reference points that mediate between the camera and the limb, making it easier for users to achieve proper alignment by simply matching the visual indicators rather than relying on complex geometric understanding.
2Loss of information
If multiple devices are used for image capture and order placement, then comprehensive data can be collected, but the ordering process becomes complicated requiring transfer of images between devices
Solution Approach 1:
The system merges multiple functions (image capture, image processing, measurement tools, order form completion, and data submission) into a single mobile device application. This consolidation eliminates the need to transfer images between devices and reduces the complexity of the ordering process while maintaining all necessary data collection capabilities.
Solution Approach 2:
The mobile device application is designed as a universal tool that performs multiple functions: capturing aligned images, providing measurement guidance, storing patient information, configuring brace parameters, and submitting orders. This multi-functionality replaces the need for separate cameras, measurement tools, and order forms, streamlining the entire ordering process into one integrated system.
3Reliability
If conventional cameras without orientation feedback are used, then simple device operation is maintained, but the photographer cannot determine whether the image meets manufacturer requirements
Solution Approach 1:
The system provides real-time feedback through visual indicators (green/red alignment markers, crosshairs, and guidance overlays) that show the user whether the camera is properly aligned with the limb. This feedback loop allows the user to adjust the camera angle and position until the alignment criteria are met, ensuring accurate limb dimension capture without requiring professional photography skills.
Solution Approach 2:
The system enables the user to self-verify image quality through built-in alignment indicators and real-time feedback. Users can independently determine whether their captured images meet the required specifications without needing external validation or specialized knowledge, empowering them to take control of the image quality assurance process.
