Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing orthopedic devices, particularly orthoses and prostheses, often fail to adequately customize the devices to individual patient needs and preferences, both aesthetically and functionally, due to limited consideration of patient-provided information during the production process.
Innovation Solution
A computer-implemented method involving the receipt and processing of patient data to create personalized models, allowing for iterative customization through user input and the use of advanced scanning technologies like laser or CT scans, combined with 3D printing and visualization tools to produce highly customized orthopedic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If standardized modular systems are used for producing orthopedic devices, then manufacturing efficiency and cost are improved, but customization capability to individual patient needs deteriorates
Solution Approach 1:
The system performs preliminary actions by creating virtual 3D models of patient anatomy and device configurations before actual manufacturing. This allows customization parameters to be determined and approved in advance, enabling standardized production processes to be applied to customized designs efficiently.
Solution Approach 2:
The system creates virtual copies (digital twins) of patient anatomy through scanning and modeling, and virtual copies of device configurations through parametric modeling. These digital models enable customization without requiring physical prototypes or manual fabrication, maintaining manufacturing efficiency while achieving high customization.
2Adaptability or versatility
If extensive patient data collection and iterative design processes are implemented, then device customization and patient satisfaction are improved, but production time and process complexity deteriorate
Solution Approach 1:
The system implements dynamic, iterative design processes where virtual models can be continuously adjusted based on patient feedback and clinical requirements. The parametric models allow real-time modification of device parameters while automatically maintaining geometric constraints and manufacturing feasibility, enabling customization without excessive time loss.
Solution Approach 2:
The system incorporates feedback loops where patient input and clinical expert input are systematically integrated into the virtual modeling process. This structured feedback mechanism allows iterative refinement of device parameters while tracking changes and maintaining version control, reducing the time impact of extensive customization processes.
3Adaptability or versatility
If detailed patient parameters and aesthetic preferences are incorporated into device design, then aesthetic acceptability and patient confidence are improved, but device complexity and production cost deteriorate
Solution Approach 1:
The system applies local quality by allowing different regions of the orthopedic device to have different properties - functional regions are optimized for medical performance while aesthetic regions can be customized for appearance. The virtual modeling system enables independent parameter control for different device sections, managing overall complexity while achieving localized customization.
