Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If force sensor systems are designed for specific applications with fixed configurations, then they can provide reliable measurements for that specific application, but they lack the flexibility to measure force data in various positions and cannot accurately reflect real movement patterns during different sports
Solution Approach 1:
The force sensor system employs dynamic positioning capabilities through motor-driven adjustment mechanisms that allow the sensor to move along rails and reposition itself in three-dimensional space. This enables the system to adapt to different measurement positions and orientations required by various sports applications without requiring multiple fixed sensor configurations.
Solution Approach 2:
The system integrates a universal positioning framework that can accommodate different force sensor configurations for multiple sports applications. The motorized adjustment system, combined with programmable control, allows a single system to serve multiple functions across different athletic disciplines, eliminating the need for application-specific fixed sensor installations.
2Measurement precision
If force sensors are positioned at fixed locations, then the measurement setup is simple and stable, but the system cannot accurately capture movement patterns and asymmetries in athletic performance
Solution Approach 1:
The system incorporates automated positioning mechanisms where motors drive the force sensor along predefined rails to achieve precise measurement positions. The programmable control system automatically adjusts sensor location based on measurement requirements, eliminating the need for manual positioning and reducing setup complexity while maintaining high measurement precision.
Solution Approach 2:
The system employs location sensors to detect the actual position of the force sensor during adjustment and feeds this information back to the control system. This feedback mechanism ensures accurate positioning and allows the system to compensate for positioning errors, maintaining measurement precision while simplifying the operation through automated position verification.
3Adaptability or versatility
If the force sensor system includes adjustable components for multiple positions, then it can reflect various movement patterns, but the system becomes more complex with additional adjustment mechanisms
Solution Approach 1:
The positioning system is divided into modular segments with independent motor-driven adjustment mechanisms along different axes. Each segment can be adjusted independently, allowing the force sensor to reach multiple positions through a systematic combination of simple linear movements rather than complex single-motion mechanisms.
Solution Approach 2:
The system replaces manual mechanical adjustment with motorized positioning mechanisms that can be controlled programmatically. This substitution reduces the complexity of manual operation and allows for more precise and repeatable positioning through electronic control rather than complex mechanical linkages.
