Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acceleration sensor and control circuit are added to predict user movement, then safety device deployment is optimized, but device complexity increases
Solution Approach 1:
The control circuit serves multiple functions: it monitors braking controller operation, monitors steering controller operation, calculates longitudinal acceleration effects on user position, calculates lateral acceleration effects on user position, and determines optimal airbag deployment parameters. By making the control circuit multi-functional, the patent avoids adding separate dedicated components for each function, thereby optimizing safety device deployment while limiting the increase in device complexity.

AI summary
Disclosed herein is an apparatus for predicting movement of a user of a vehicle. The apparatus may include an acceleration sensor that senses an acceleration of the vehicle, a braking controller that automatically controls a deceleration of the vehicle, a steering controller that automatically controls a direction of the vehicle, and a control circuit electrically connected to the acceleration sensor, the braking controller, and the steering controller, where the control circuit may monitor an operation of the braking controller, and predict a movement of the user of the vehicle based on a longitudinal acceleration of the vehicle sensed by the acceleration sensor and a first predetermined parameter when braking by the braking controller is detected.
