Infant Carrier Backrest Angle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant carriers with non-adjustable or complexly structured backrests fail to provide comfort and adaptability, as they are either too rigid or overly complicated, affecting user experience and manufacturing costs.
Innovation Solution
A backrest angle adjusting mechanism comprising a fixing member and an adjusting member, where the adjusting member slides on the fixing member to rotate the backrest, allowing for easy adjustment between upright and lying positions, reducing manufacturing costs and enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the backrest is fixedly arranged with the seat body, then the structure is simple, but the adaptability and comfort are reduced due to non-adjustable inclination angle
Solution Approach 1:
The adjusting member is divided into a first adjusting section and a second adjusting section that can slide relative to each other along the fixing member. This segmentation allows independent adjustment of each section's length, enabling continuous backrest angle variation while keeping the overall mechanism simple.
Solution Approach 2:
The patent transforms the fixed backrest structure into a dynamic adjustable one by introducing sliding sections that can change length. The first and second adjusting sections can slide along the fixing member, allowing the backrest inclination angle to be dynamically adjusted between upright and lying positions.
2Adaptability or versatility
If a complex adjustment mechanism is used to make the backrest angle adjustable, then the adaptability is improved, but the manufacturing cost and operational complexity increase
Solution Approach 1:
By dividing the adjusting member into two sliding sections, the patent achieves angle adjustability using simple sliding movements rather than complex mechanisms like gears or linkages. This segmentation allows each component to be manufactured independently with simple geometries, reducing production costs.
Solution Approach 2:
The patent uses simple sliding sections that can be manufactured from basic materials without requiring precision machining or expensive components. The adjusting sections are designed to be simple rod-like structures that slide within grooves, minimizing manufacturing complexity and cost.
3Adaptability or versatility
If a complex adjustment mechanism is used to make the backrest angle adjustable, then the adaptability is improved, but the operation becomes complex and inconvenient
Solution Approach 1:
The adjusting member is segmented into two sections that slide independently along the fixing member. This segmentation allows the user to adjust the backrest angle by simply sliding one or both sections, creating an intuitive and easy-to-operate mechanism that requires minimal effort.
Solution Approach 2:
The sliding sections are designed to move freely along the fixing member under user input, with no additional locking mechanisms or complex controls required. The user directly manipulates the adjusting sections to achieve the desired backrest angle, making the system self-adjusting and extremely user-friendly.

AI summary
A backrest angle adjusting mechanism, suitable for being assembled between a seat body and a backrest of an infant carrier, having the seat body being installed on a frame, the backrest being rotatably connected to the seat body, and wherein the backrest angle adjusting mechanism includes a fixing member and an adjusting member. The fixing member is fixed on the backrest, one end is connected to the seat body or frame to form a connecting part, and the other end is bypassed around the fixing member to form an operating part. Operating the operating part causes the adjusting member to slide on the fixing member, and sliding the adjusting member brings the backrest to rotate with respect to the seat body, thereby adjusting an inclination angle of the backrest.
