Child Seat Abutting Mechanism With Locking and Auto-Reset Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat adjustment mechanisms are complex, difficult to manufacture, costly, prone to operation failures, and lack automatic resetting, leading to cumbersome adjustment and disassembly processes, with insufficient fixation and support causing the seat to swing during use.
Innovation Solution
An abutting and bearing device with a casing, abutting member, driving assembly, locking assembly, and resetting assembly, allowing for easy extension and retraction of the abutting member to securely fit the child safety seat to the car seat back, featuring a control member for operation and automatic resetting functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a complex adjustment mechanism with multiple components is used to adjust the ejector rod angle, then the fit between the child safety seat and car seat back is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The adjustment mechanism is divided into independent functional modules: the ejector rod for angle adjustment, the locking member for position fixation, and the driving member for actuation. Each module performs a specific function, allowing for simplified manufacturing and assembly while achieving the desired adjustment capability.
Solution Approach 2:
The adjustment function is extracted from the main seat structure and implemented as a separate, dedicated mechanism. This allows the adjustment system to be optimized independently, reducing overall complexity by isolating the adjustment functionality from other seat components.
2Adaptability or versatility
If multiple components with connection and movement cooperation are used for adjustment, then the adjustability is improved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The mechanism uses dynamic elements such as the slidable locking member and the spring-loaded ejector rod that can move along defined paths. This dynamic design provides continuous adjustment range while maintaining simple component geometries that are easy to manufacture using standard machining processes.
3Adaptability or versatility
If a multi-component adjustment mechanism is used, then the adjustment capability is improved, but the ease of operation deteriorates due to complex operations in multiple directions
Solution Approach 1:
The locking and adjustment functions are merged into a single operational sequence. The locking member simultaneously controls both the adjustment position and the locked state, allowing the user to perform adjustment and locking with one continuous action rather than separate operations.
Solution Approach 2:
The spring-loaded ejector rod provides automatic return to the initial position after adjustment. When the locking member is released, the spring automatically resets the ejector rod, eliminating the need for manual resetting operations and simplifying the user interaction.
4Stability of the object's composition
If the ejector rod angle is adjusted to improve fit, then the seating comfort is improved, but the time required for adjustment and disassembly increases due to lack of automatic resetting
Solution Approach 1:
The spring-loaded ejector rod automatically returns to its initial retracted position when the locking member is released. This self-resetting feature eliminates the need for manual retraction operations, allowing quick disassembly and readjustment without time-consuming manual interventions.
Solution Approach 2:
The mechanism is designed for rapid cyclic operation between adjusted and reset states. The spring-loaded reset provides quick periodic return to the initial position, enabling frequent adjustments without significant time loss, thus supporting periodic use patterns typical in child safety seat applications.
