Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors and actuators are integrated into athletic wear to provide real-time feedback, then user performance and movement accuracy are improved, but device complexity increases
Solution Approach 1:
The system divides the feedback mechanism into separate functional modules: sensors for data collection, processing unit for analysis, and actuators for feedback delivery. Each component is independently integrated into the garment at specific locations, allowing modular assembly and maintenance while achieving comprehensive movement monitoring and correction
Solution Approach 2:
The processing unit serves multiple functions: it receives data from various sensor types (accelerometers, gyroscopes, position sensors), processes this information to detect movement deviations, generates appropriate feedback instructions, and controls different actuator types. This multi-functionality reduces the need for separate dedicated components for each function
2Reliability
If multiple sensors and actuators are integrated into the smart garment, then real-time feedback capability is improved, but weight of the garment increases
Solution Approach 1:
Sensors and actuators are strategically positioned at specific locations on the garment where they are most needed for detecting and correcting movement deviations. For example, sensors are placed at joints and actuators positioned to provide feedback at key body parts, rather than uniformly distributing components throughout the entire garment, thereby minimizing unnecessary weight
Solution Approach 2:
The system uses lightweight sensor and actuator technologies with optimized performance parameters. Sensors such as accelerometers and gyroscopes are selected based on their sensitivity and accuracy requirements rather than using over-specified components, and actuators are sized appropriately to provide effective haptic feedback without excessive mass
3Measurement precision
If real-time data processing and feedback are implemented, then user guidance accuracy is improved, but energy consumption increases
Solution Approach 1:
The processing unit operates in periodic cycles, collecting sensor data over short intervals, processing this batch of information to detect movement deviations, generating feedback instructions, and updating the actuators. This periodic operation allows the system to maintain real-time feedback capability while reducing peak processing demands and overall energy consumption compared to continuous operation
Solution Approach 2:
The system processes only the essential sensor data needed for detecting movement deviations and generating corrective feedback, rather than analyzing all possible parameters. The processing unit focuses on critical movement parameters and thresholds, performing partial processing that is sufficient for effective feedback while minimizing computational energy expenditure
