Safety Seat Base Inclination Locking Mechanism for Infant Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional child safety seat and infant carrier bases lack inclination adjustment, making it difficult to achieve a comfortable seating or lying position for infants, as their position needs to change based on mood and comfort.
Innovation Solution
An inclination adjustment mechanism featuring a base with positioning indents, a pivoted heelpiece with a protruded portion for selective engagement, and a spring-loaded press button to change the inclination position by releasing the protruded portion from the indents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional fixed base is used for safety seat, then the structure is simple and stable, but the infant cannot obtain a comfortable angle to sit or lay down
Solution Approach 1:
The base is designed with a pivoted heelpiece that can rotate relative to the base body, transforming the fixed static structure into a dynamic adjustable one. The heelpiece can be positioned at multiple angles through engagement with positioning indents, allowing the base inclination to be adjusted while maintaining structural stability during use.
Solution Approach 2:
The base is divided into separate functional components: the base body, the pivoted heelpiece, and the spring-loaded press button mechanism. This segmentation allows independent adjustment of the heelpiece angle while keeping the base body stable, enabling comfort adjustment without complicating the overall structure.
2Adaptability or versatility
If inclination adjustment mechanism is added to the base, then comfortable positioning is achieved, but the mechanism complexity increases
Solution Approach 1:
The spring-loaded press button automatically engages with the heelpiece to lock it in position once the desired inclination is reached. The spring mechanism provides automatic resetting and locking functionality, eliminating the need for additional locking mechanisms or complex control systems while maintaining multiple position adaptability.
Solution Approach 2:
The spring-loaded press button acts as an intermediary element between the user's manual input and the heelpiece positioning system. It translates simple button pressure into precise engagement with the positioning indents, providing smooth adjustment without requiring complex direct manipulation mechanisms.
3Adaptability or versatility
If multiple positioning indents are provided, then various inclination positions are available, but the base structure becomes more complex
Solution Approach 1:
The positioning indents are localized to specific areas on the base body where they engage with corresponding features on the heelpiece. This localized arrangement provides multiple discrete positioning options without requiring complex structural modifications across the entire base, maintaining simplicity while offering versatility.

Function Achieved in This Case
Enables easy adjustment of the base's inclination to provide a comfortable seating or lying position for infants, reducing installation difficulties and user time consumption.
Implementation Method 1
a spring-loaded press button operatively connected to one end of the heelpiece for releasing the protruded portion from the positioning indents
Implementation Method 2
The heelpiece is pivoted to the base and formed with a protruded portion for selectively engaging with one of the positioning indents

AI summary
An inclination adjustment mechanism for a base of safety seat includes a base, a heelpiece and a spring-loaded press button. The base has one end formed with a plurality of positioning indents, and a upper surface for supporting a safety seat. The heelpiece is pivoted to the base and formed with a protruded portion for selectively engaging with one of the positioning indents thereby to keep the base in a selected inclination position. The spring-loaded press button is operatively connected to one end of the heelpiece for releasing the protruded portion from the positioning indents, so as to change the selected inclination position of the base by pressing the spring-loaded press button and moving one end of the base relative to the heelpiece.
