Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sofa uses traditional fixed seat structure, then structural stability is maintained, but user convenience is limited due to inability to automatically adjust seat position
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed seat structure into a movable one. The seat unit is equipped with a seat actuator that enables automatic movement along the longitudinal direction, allowing the seat position to be dynamically adjusted according to user needs while maintaining structural stability through guided motion paths.
Solution Approach 2:
The patent uses the seat actuator as an intermediary component between the control system and the seat unit. This actuator includes a sliding body, rotary unit, and coupling mechanisms that mediate the movement, enabling convenient automatic adjustment while managing the complexity through modular design.
2Ease of operation
If a sofa implements automatic seat movement technology, then user convenience is greatly improved, but structural stability becomes difficult to achieve
Solution Approach 1:
The rotary unit acts as an intermediary mechanism that enables smooth movement of the seat unit while maintaining structural stability. It includes a link member coupled to the seat coupling body, a rotary body that rotates to push the seat unit, and a rotary arm that guides the motion, ensuring stable and controlled movement.
Solution Approach 2:
The seat actuator is configured to automatically move the seat unit along the longitudinal direction without requiring manual intervention. The driving motor automatically drives the sliding body, which in turn moves the seat coupling body and the seat unit, providing self-service functionality that improves convenience while maintaining stability through automated controlled movement.
3Adaptability or versatility
If a sofa uses simple seat structure, then manufacturing is easier and cost is lower, but functionality is limited without automatic movement capability
Solution Approach 1:
The patent applies segmentation by dividing the seat system into independent functional modules: the seat unit, the seat actuator (with driving motor, sliding body, and rotary unit), and the coupling mechanisms. This modular segmentation enhances functionality and adaptability while facilitating easier manufacturing and assembly of individual components.
Solution Approach 2:
The patent introduces dynamic functionality through the seat actuator system that enables automatic movement of the seat unit. This adds versatility to the sofa, allowing it to adapt to different user positions and preferences, while the modular design of the actuator components maintains manufacturing ease.
