Baby Carrier Recline Structure With Adjustable Backrest-Leg Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby carriers cannot adjust the angle between the backrest and leg support surfaces, failing to accommodate different baby postures.
Innovation Solution
A lying position adjusting structure featuring a first slider, a second slider, and an adjusting component, with one end of the second slider hinged to the housing and the other end hinged to the first slider through a rotating shaft, allowing the angle between the sliders to be adjusted for different positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the baby carrier has an integral structure with fixed relative positions of backrest and leg support parts, then the structure is simple and easy to manufacture, but the angle between backrest support surface and leg support surface cannot be adjusted, reducing adaptability to different baby postures
Solution Approach 1:
The baby carrier is divided into separate modular components: a backrest assembly with first slider, a leg support assembly with second slider, and a rotating shaft connecting them. This segmentation allows independent adjustment of each component while maintaining overall structural simplicity through standardized connection interfaces.
Solution Approach 2:
The patent transforms the static integral structure into a dynamic adjustable structure by introducing a rotating shaft that enables angle adjustment between the backrest and leg support. The slider mechanisms provide dynamic positioning capability, allowing the carrier to adapt to different baby postures while maintaining structural integrity through controlled movement.
2Ease of operation
If the baby carrier uses an integral structure with fixed angles, then the manufacturing precision requirements are lower, but the ease of operation is reduced due to inability to adjust to different baby needs
Solution Approach 1:
The slider mechanisms are designed to self-align within the hinge connections and rotating shaft interfaces. The geometric constraints of the slider-crank mechanism automatically guide the components into proper alignment during adjustment, reducing the need for high-precision manual assembly while ensuring repeatable positioning.
Solution Approach 2:
The hinge connections and rotating shaft interfaces are pre-designed with built-in alignment features and tolerance compensation mechanisms. The slider paths are pre-configured to guide components into correct positions, eliminating the need for complex alignment procedures during assembly and operation.
3Adaptability or versatility
If the baby carrier allows angle adjustment between backrest and leg support, then adaptability to different postures is improved, but the device complexity increases due to additional hinges and adjusting components
Solution Approach 1:
The rotating shaft serves multiple functions: it connects the backrest and leg support assemblies, enables angle adjustment, provides a pivot point for the slider mechanisms, and acts as a structural support element. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving posture adjustment capability.
Solution Approach 2:
The patent merges the adjustment mechanism with the structural support elements. The rotating shaft and hinge connections serve both as structural components and as the adjustment mechanism itself, eliminating the need for separate adjustment devices and minimizing the increase in overall device complexity.
