Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child car seat devices have complex and costly mechanisms for adjusting headrest wings, lack backrest wings, and fail to adequately protect the child's body and head.
Innovation Solution
A child car seat device with simplified wing components, including pivotally connected headrest and backrest assemblies, featuring engaging portions and pivoting blocks that allow adjustable angles for enhanced protection and reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional headrest wings are adjusted by operating knob and link mechanism, then the headrest wings can be adjusted, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent removes the complex knob and link mechanism from the conventional design. Instead, the headrest wings are directly pivotally connected to the headrest body through simple pivot points, extracting the unnecessary intermediate components while retaining the adjustment functionality.
Solution Approach 2:
Rather than using a mechanism that translates rotational motion through links and knobs to achieve wing adjustment, the invention inverts the approach by allowing direct pivotal rotation at the connection points. The adjustment is achieved through simple angular movement at the pivot points rather than through a complex transmission mechanism.
2Object-affected harmful factors
If conventional child car seat device lacks backrest wings, then the structure is simpler, but the body of the child is not under protection
Solution Approach 1:
The patent divides the protective structure into separate functional segments: headrest wings for head protection and backrest wings for body protection. Each wing is independently pivotally connected and can be adjusted separately, allowing targeted protection for different body regions without requiring a monolithic complex structure.
Solution Approach 2:
The backrest wings serve multiple functions: they provide lateral support for the child's body, enhance overall structural stability, and can be adjusted to accommodate different child sizes and positions. This multi-functionality adds protection value without proportionally increasing complexity.
3Adaptability or versatility
If headrest wings are made adjustable through complex mechanism, then adaptability improves, but manufacturing cost increases
Solution Approach 1:
The invention extracts and eliminates the expensive knob, link, and channel components from the adjustment mechanism. The adaptability is achieved through simple pivotal connections that allow angular adjustment without requiring precision-machined transmission components, significantly reducing manufacturing and assembly costs.
Solution Approach 2:
The patent employs simple, inexpensive pivot points and engaging portions instead of costly mechanical adjustment mechanisms. These simple components can be easily manufactured and replaced if needed, providing cost-effective adaptability compared to complex permanent mechanisms.

AI summary
A child car seat device with wing components includes a seat assembly, a backrest assembly and a headrest assembly, which are each connected together. The headrest assembly includes a headrest body, two headrest wing components, and two pivots passing through the headrest body and headrest wing components. Each pivot is retained by a fastener or a tab extending from the headrest wing component. The headrest body has a plurality of grooves and the headrest wing component has a rib. An angle defined between the headrest wing component and the headrest body can be changed by engaging the rib within different grooves. The headrest body has a stopper so that the headrest wing component cannot be pivotally rotated further outwards when it abuts against the stopper. The structures of the backrest assembly are similar to those of the headrest assembly. In addition, the seat device may be provided with the headrest wing components and/or backrest wing components.
