Orthopedic Device Usage Data Evaluation via Sensor Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating the usage of orthopedic devices rely on subjective user feedback, which is unreliable, especially for short-term uses or loan equipment, lacking objective data on correct usage and functionality.
Innovation Solution
A method involving sensors connected to a transmitter that sends data to an evaluation unit in a computer network for processing and evaluation, allowing for objective assessment of usage data, including movement and load data, via wired or wireless transmission, and incorporating user assessments for comprehensive analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If standardized questionnaires are used for data collection, then user feedback can be obtained, but the data reliability is low due to subjective perception differences
Solution Approach 1:
The patent replaces the mechanical/questionnaire-based data collection system with an electronic sensor system. Sensors objectively measure usage parameters such as weight, height, volume, and usage time, eliminating subjective user perception and providing reliable, quantifiable data for evaluating orthopedic device fit and usage.
2Measurement precision
If sensor data collection system is implemented, then objective usage data can be obtained, but device complexity increases
Solution Approach 1:
The patent integrates multiple sensing functions into a single evaluation system that can assess various orthopedic devices (braces, prosthetics, splints) using the same platform. The system collects diverse data types (weight, height, volume, usage time) through a unified sensor network, reducing overall system complexity while maintaining measurement precision.
3Reliability
If real-time data transmission is implemented, then continuous monitoring is achieved, but energy consumption increases
Solution Approach 1:
The patent implements periodic data transmission instead of continuous real-time transmission. Sensors collect usage data continuously, but transmission to the evaluation system occurs at predetermined intervals or when specific thresholds are reached, maintaining monitoring reliability while significantly reducing energy consumption of the orthopedic device.
Data Source
AI summary
The invention relates to a method for evaluating usage data of at least one orthopaedic device which is equipped with sensors for detecting properties, states, or changes in properties or states, wherein the sensors are connected to a transmitter directly or via a storage device and the transmitter transmits the sensor data provided by the sensors to an evaluation unit in a computer network in which the sensor data is processed.
