Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the safety seat is installed in a fixed position to ensure stability, then the installation stability is improved, but the leg movement space of the child occupant is restricted
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed installation position into a dynamically adjustable one. The safety seat is equipped with electric units that enable the seat body to perform rotational and translational movements, allowing the seat to change its position and orientation after installation. This resolves the contradiction by maintaining installation stability through secure mounting while dynamically adjusting the seat position to maximize leg movement space for the child occupant.
Solution Approach 2:
The patent segments the movement control into two independent electric units: a first electric unit for rotational movement and a second electric unit for translational movement. This segmentation allows independent control of different movement dimensions, enabling the system to optimize leg movement space by adjusting rotation and translation separately while maintaining overall installation stability.
2Ease of operation
If the seat body is adjusted to multiple positions to improve comfort, then the ride comfort is improved, but the control complexity increases
Solution Approach 1:
The patent implements feedback mechanisms through feedback signals that monitor the position and state of the electric units. The control system receives feedback information about the seat body's position and the operational state of the electric units, enabling automatic control and precise positioning. This feedback loop simplifies the control process by eliminating the need for manual complex adjustments while ensuring the seat reaches the desired position for optimal comfort.
Solution Approach 2:
The control system operates autonomously by receiving feedback signals and automatically controlling the electric units to achieve the desired seat position. The system performs self-service by independently managing the rotational and translational movements without requiring complex manual intervention, thereby improving ride comfort while keeping the control system manageable.
3Measurement precision
If feedback signals are implemented to improve positioning precision, then the positioning accuracy is improved, but the system complexity increases
Solution Approach 1:
The patent uses feedback signals to monitor the position of the seat body and the state of the electric units during movement. The control system processes this feedback information to determine when the seat has reached the target position and to detect any abnormal resistance or obstacles. This feedback mechanism improves positioning accuracy by providing real-time information about the system state while maintaining relatively simple implementation through straightforward signal monitoring and basic control logic.
