Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the safety seat is installed in a fixed position to ensure stability, then installation reliability is improved, but the leg movement space and comfort of the child occupant deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed installation structure into a dynamic adjustable one. The seat body is equipped with electric units that enable it to perform translational movements along the vehicle width direction and rotational movements, allowing the installation position and angle to be adjusted according to different scenarios, thus resolving the contradiction between installation reliability and leg movement space.
Solution Approach 2:
The patent divides the adjustment function into multiple independent electric units: a first electric unit for translational movement and a second electric unit for rotational movement. This segmentation allows each unit to independently control a specific degree of freedom, enabling precise adjustment of the seat position and angle while maintaining installation reliability.
2Ease of operation
If the seat body is adjusted to expand leg movement space, then comfort is improved, but positioning accuracy and safety deteriorate
Solution Approach 1:
The patent implements feedback mechanisms through feedback signals that provide real-time information on the position and movement state of the seat body. The control system uses this feedback to accurately determine when the seat has reached the target position, ensuring positioning accuracy while allowing comfortable adjustment ranges.
Solution Approach 2:
The patent replaces manual mechanical adjustment with electric units that provide precise, controlled movement. The electric units offer better positioning accuracy compared to manual adjustment while still providing sufficient movement range for comfort, effectively resolving the contradiction between comfort and positioning accuracy.
3Device complexity
If feedback signal detection is simplified to reduce system complexity, then device complexity is reduced, but positioning precision and safety deteriorate
Solution Approach 1:
The patent uses feedback signals from sensors to detect the position and movement state of the seat body. This feedback mechanism provides sufficient positioning precision without requiring overly complex detection systems, as the feedback signals directly indicate whether the seat has reached the target position or encountered obstacles.
Solution Approach 2:
The control system automatically determines the movement state of the electric units based on the received feedback signals, without requiring complex external intervention. The system self-regulates by interpreting the feedback signals to control the electric units, maintaining positioning precision while keeping the system relatively simple.
