Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing correction products focus on specific body parts only, then manufacturing complexity is reduced, but the ability to correct interrelated body movement and posture imbalances is insufficient
Solution Approach 1:
The patent integrates multiple correction functions into a single comprehensive system that simultaneously addresses posture correction, movement analysis, and balance training. The wearable device combines IMU sensors, pressure sensors, and multiple actuators to provide holistic correction for spinal, pelvic, and lower limb alignment issues, rather than targeting isolated body parts.
Solution Approach 2:
The correction system is divided into multiple functional modules: sensing modules (IMU sensors, pressure sensors), control modules (microcontroller), and actuation modules (vibrating motors, linear actuators). Each module performs a specific function but works together as an integrated system to achieve comprehensive posture and movement correction.
2Reliability
If comprehensive body movement and posture correction is implemented, then correction effectiveness is improved, but device complexity increases
Solution Approach 1:
The system continuously monitors body posture and movement through IMU sensors and pressure sensors, compares real-time data with target posture parameters, and provides real-time feedback through vibrations and resistance forces. This closed-loop feedback mechanism ensures accurate and reliable correction while managing system complexity through algorithmic control.
Solution Approach 2:
The patent introduces a microcontroller as an intermediary that processes sensor data, calculates posture deviations, and controls actuator outputs. This intermediary layer simplifies the control architecture by centralizing decision-making logic and coordinating multiple sensors and actuators without requiring direct complex interactions between them.
3Measurement precision
If multiple sensors and measurements are used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensing functions into integrated sensor modules. IMU modules simultaneously measure acceleration, angular velocity, and orientation. Pressure sensor arrays are integrated into the insole to detect foot pressure distribution. This merging of functions reduces the number of separate components while maintaining high measurement precision.
