Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional measurement and testing systems use a large measurement surface area, then they can capture overall movement, but they cannot separately analyze the movement of individual legs
Solution Approach 1:
The measurement system is divided into multiple independent force measurement assemblies, each capable of measuring forces independently. This segmentation allows the system to analyze movement of individual legs separately while maintaining overall measurement capability across the entire measurement surface.
2Adaptability or versatility
If conventional measurement and testing systems are configured with large measurement surface areas, then they provide comprehensive coverage, but they are difficult to install and adapt to different space configurations
Solution Approach 1:
The system uses multiple modular force measurement assemblies that can be independently installed and configured. Each assembly is a self-contained unit that can be adapted to different spatial arrangements, allowing the overall system to be easily installed and reconfigured for various space configurations without requiring complex integrated structures.
3Adaptability or versatility
If conventional motion capture systems require specific support structures, then they provide stable measurement, but they are difficult to incorporate in natural environments outside of gait labs
Solution Approach 1:
The force measurement assemblies are extracted from complex support structures and designed as standalone modular units. Each assembly contains its own measurement capabilities and can be independently installed in natural environments without requiring elaborate support frameworks, thereby enabling deployment outside traditional gait laboratory settings.
4Loss of information
If the system combines data channels from various devices with different sampling rates, then it integrates comprehensive measurement data, but it requires complex synchronization
Solution Approach 1:
The data acquisition and processing device is designed with universal data handling capabilities that can accept and process data from multiple sources with different sampling rates. The device automatically synchronizes and integrates these diverse data streams into a unified time-coordinated dataset, eliminating the need for complex external synchronization mechanisms while maintaining complete measurement information.
