Goniometer Axis Filtering for Rotation-Resistant Angle Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current goniometers suffer from inaccuracies due to unintentional rotations during angle measurements, which can significantly impact medical diagnoses and treatments.
Innovation Solution
The enhanced goniometer selectively filters or disables measurements along certain axes using a computing component to compensate for unintentional rotations, ensuring accurate angle measurements by isolating relevant axes for a specific measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the goniometer measures angles using multiple axes simultaneously, then it can capture comprehensive movement data, but unintentional rotations during measurement cause inaccuracies
Solution Approach 1:
The patent segments the measurement process by identifying and isolating the relevant axis for each specific movement type. The system divides the three-axis measurement capability into selective single-axis or dual-axis measurements based on the movement being assessed, thereby capturing comprehensive data while eliminating interference from unintentional rotations on irrelevant axes.
Solution Approach 2:
The patent applies local quality by tailoring the measurement approach to each specific movement type. Different movements require different axis configurations, and the system adjusts which axes are actively measured based on the local requirements of each assessment, ensuring high precision for each specific measurement while maintaining overall versatility.
2Quantity of substance
If the goniometer uses all available sensors for measurement, then data collection is comprehensive, but processing and identifying relevant measurements becomes complex
Solution Approach 1:
The patent extracts only the relevant axis measurements needed for each specific movement type from the complete three-axis sensor data. By taking out and isolating the necessary measurements while excluding irrelevant ones, the system maintains comprehensive data collection capability while significantly simplifying the processing requirements.
Solution Approach 2:
The patent performs preliminary action by pre-defining which axes are relevant for each movement type before measurement begins. This advance planning and configuration reduces the complexity of real-time data processing, as the system already knows which sensor outputs to focus on for each assessment.
3Ease of operation
If the goniometer provides detailed guidance for each measurement step, then ease of operation improves, but the user interface becomes more complex
Solution Approach 1:
The patent applies dynamics by making the user interface adaptive and context-dependent. The guidance provided to users changes dynamically based on the specific movement being measured, presenting only the relevant instructions and information needed for each assessment type, thereby improving ease of operation without requiring a permanently complex interface.
