Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed installation is adopted for the baby rocking chair, then the structure is stable, but it becomes difficult to disassemble for cleaning and maintenance, and bulky when transporting
Solution Approach 1:
The rocking chair is divided into separable components: the seat assembly and the base assembly. The connection between them uses a quick-release mechanism that allows easy separation while maintaining structural integrity when connected. This segmentation enables the chair to be disassembled for cleaning, maintenance, and storage while remaining stable during use.
2Device complexity
If a simple rotating shaft and slot structure is used for backrest adjustment, then the structure is simple, but the adjustment is inconvenient, offers few angle positions, and positioning is unreliable
Solution Approach 1:
The backrest adjustment mechanism transitions from a static simple shaft-slot structure to a dynamic system with multiple locked positions. The pull-rope mechanism allows the backrest to be adjusted to different angles (at least three positions) and locked reliably at each position, providing both convenience and reliability while maintaining relatively simple construction.
3Device complexity
If a single degree of freedom shaking method is used, then the structure is simple, but it cannot simulate compound movements like up-down gentle shaking combined with horizontal swing
Solution Approach 1:
The rocking chair incorporates two independent driving mechanisms: one for horizontal swinging motion and another for vertical up-down motion. This adds a second dimension of movement capability, allowing the chair to perform compound movements that combine horizontal swing with vertical gentle shaking, better simulating parental embrace movements.
4Device complexity
If the backrest angle is fixed, then the structure is simple, but it cannot adapt to different usage scenarios and baby positions
Solution Approach 1:
The backrest is designed with adjustable angle capability through the pull-rope mechanism, allowing it to transition between at least three different angles. This dynamic adjustment capability enables adaptation to various usage scenarios such as feeding, sleeping, and playing, while maintaining a relatively simple structural implementation.
