Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional analog equipment or dedicated equipment is used to capture anatomical data, then basic ROM measurement is possible, but measurement precision and data capture accuracy are insufficient
Solution Approach 1:
The patent uses a mobile device (smartphone or tablet) as a copy/alternative to specialized dedicated equipment. The mobile device captures anatomical data using its existing sensors (accelerometer, gyroscope, camera) rather than requiring purpose-built measurement devices. This approach maintains measurement capability while eliminating the need for complex dedicated equipment.
Solution Approach 2:
The patent replaces mechanical measurement systems (analog equipment, goniometers, specialized devices) with electronic sensor-based systems. The mobile device uses digital sensors (accelerometers, gyroscopes, cameras) to capture motion and anatomical data, substituting mechanical measurement approaches with electronic/digital detection methods that provide higher precision.
2Ease of operation
If conventional equipment outputs raw ROM data only, then simple measurement is achieved, but ease of operation and analytical capability are limited
Solution Approach 1:
The mobile device performs multiple functions: it captures ROM measurements, records postural data, takes photographs, and provides analytical processing. Rather than requiring separate dedicated equipment for each measurement type, the mobile device serves as a universal tool that handles multiple assessment functions, improving ease of operation while capturing comprehensive anatomical information.
Solution Approach 2:
The system provides real-time feedback and analysis of captured anatomical data. The mobile device processes the raw sensor data to generate meaningful assessments, visualizations, and insights that are immediately available to the operator. This feedback loop transforms raw data into actionable information without losing any measurement details.
3Productivity
If conventional equipment is used, then basic measurement is possible, but productivity and assessment efficiency are reduced
Solution Approach 1:
The mobile device performs preliminary processing and analysis of anatomical data immediately after capture. Rather than requiring separate time-consuming analysis steps later, the system pre-processes the sensor data, generates initial assessments, and prepares results for immediate review. This preliminary action significantly reduces the time needed for complete assessment workflows.
Solution Approach 2:
The system performs self-service by automatically processing captured anatomical data through integrated algorithms. The mobile device autonomously analyzes ROM measurements, compares them against normative data, generates assessments, and creates visualizations without requiring manual intervention or separate analysis equipment. This automation eliminates time loss associated with manual data processing and analysis.

AI summary
A mobile device may be configured to capture anatomical data for a subject and perform an assessment of a functional movement of the subject based on the anatomical data for the subject by, capturing the anatomical data for the subject via the mobile device such that the anatomical data includes range of motion (ROM) or postural measurements of one or more joints of the subject determined based on a rotation of the mobile device along a z-axis collected by one or more of an accelerometer and a gyroscope embedded within the mobile device, instructing a server to analyze the functional movement of the subject based on the anatomical data and to generate assessment data based on same, and displaying, via a user interface of the mobile device, the anatomical data and the assessment of the functional movement of the subject based on the assessment data received from the server.
