Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats with rotatable structures have complicated designs, high manufacturing costs, and inconvenient rotation operations.
Innovation Solution
A seat rotation adjustment structure featuring a release handle assembly with a handle body, positioning plate, and reset members, allowing the positioning plate to lock or disengage from positioning grooves on a rotary disc, enabling simple and stable rotation and locking operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional seat rotation adjustment structure is used, then the structure is simple, but the adjustment process is complex and requires multiple steps
Solution Approach 1:
The patent combines the rotation adjustment mechanism and height adjustment mechanism into a single integrated structure. The support rod serves dual functions: it enables both rotational movement of the seat and height adjustment of the seat assembly, eliminating the need for separate adjustment mechanisms and reducing the number of operational steps.
Solution Approach 2:
The support rod is designed as a multi-functional component that simultaneously provides rotation adjustment and height adjustment capabilities. This universal component performs multiple functions that would traditionally require separate mechanisms, thereby simplifying the overall device structure while maintaining ease of operation.
2Ease of manufacture
If a traditional adjustment structure is used, then the device complexity is low, but the installation process is cumbersome and time-consuming
Solution Approach 1:
The patent divides the child safety seat into modular components including the seat assembly, support rod, and base assembly that can be independently manufactured and assembled. This segmentation allows for pre-assembly of subcomponents and simplifies the final installation process, reducing installation time while maintaining manufacturing simplicity.
Solution Approach 2:
The support rod is designed with pre-configured connection interfaces and adjustment mechanisms that are prepared during manufacturing. This preliminary preparation of adjustment features and connection points enables quick installation without requiring complex assembly steps or specialized tools during the installation process.
3Adaptability or versatility
If multiple adjustment mechanisms are added to improve functionality, then the adaptability increases, but the device complexity increases
Solution Approach 1:
The patent merges the rotation adjustment mechanism and height adjustment mechanism into a single integrated support rod structure. This consolidation provides both rotational and vertical adjustment capabilities (enhancing adaptability) while using a unified mechanism (reducing device complexity) rather than separate independent systems.
Solution Approach 2:
The support rod is designed as a universal component that provides multiple adjustment functions including rotation and height adjustment through a single mechanism. This multi-functional design increases the adaptability of the child safety seat to different positioning requirements while avoiding the complexity of multiple separate adjustment systems.

AI summary
Disclosed are a seat rotation adjustment structure and a child safety seat including the same. The seat rotation adjustment structure includes a base (1) and a rotary disc (2). A release handle assembly (3) is mounted on the base (1). The release handle assembly (3) includes a handle body (31), a positioning plate (32), and a first reset member (33). A front end of the positioning plate (32) is hingedly connected to the handle body (31), and a rear end of the positioning plate (32) is connected to the first reset member (33). An accommodating space (4) is formed between the rotary disc (2) and the base (1). A plurality of positioning grooves (21) are provided on the rotary disc (2). When the positioning plate (32) is aligned with a positioning groove (21) of the positioning grooves (21), the positioning plate (32) is pushed by the handle body (31) and the first reset member (33) to lock to the positioning groove (21). Through the movement of the handle body (31) and the restriction of the movement of the positioning plate (32) by the accommodating space (4), the positioning plate (32) can be locked to or disengaged from a positioning groove (21) of the positioning grooves (21), so that the position of the rotary disc (2) can be changed to achieve seat rotation and locking. The seat rotation adjustment structure involves a simple structure, a small number of parts, and low improvement costs.
