Child Car Seat Base Interface for Sliding Cradle Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for anchoring child seats, carrycots, and carriage bodies to vehicle seats are complex, requiring multiple types of fastening means and often result in laborious and insecure fastening/unfastening processes, especially when dealing with vertical and horizontal movements, and fail to provide adequate safety and weight management during impacts.
Innovation Solution
A device featuring a car base with ISO-FIX automatic fastening tabs and an interface body with guide elements and adjustment means for easy horizontal translation, along with a cradle element and abutment body for secure and lightweight anchoring, allowing for easy fastening/unfastening and enhanced safety during impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening means are used to anchor carriage bodies to car bases, then safety during impacts is improved, but the fastening and unfastening operations become laborious and complex
Solution Approach 1:
Instead of requiring vertical and horizontal movements for fastening as in conventional solutions, the invention inverts the movement direction to purely horizontal translation. The coupling means enable the carriage body to be fastened and unfastened by simple horizontal sliding motion, making the operation intuitive and easy to perform from outside the vehicle while maintaining secure anchoring
Solution Approach 2:
The car base is designed with universal coupling means that can accommodate different types of accommodations (child seats, carrycots, and carriage bodies) through a standardized horizontal translation interface, eliminating the need for multiple specialized fastening systems
2Adaptability or versatility
If a car base is designed to support multiple types of accommodations with various fastening means, then adaptability is improved, but device complexity increases
Solution Approach 1:
The invention implements a universal coupling interface on the car base that works with all types of accommodations (child seats, carrycots, carriage bodies). This single standardized horizontal translation mechanism replaces multiple specialized fastening systems, achieving multi-functionality without increasing complexity
Solution Approach 2:
The coupling system is segmented into standardized components: the car base provides the coupling interface, while each accommodation type provides corresponding engagement elements. This modular segmentation allows different accommodations to interface with the same car base through standardized horizontal translation without requiring complex integrated designs
3Ease of operation
If carriage bodies are fastened at front or rear regions, then coupling is achieved, but excessive deformation during impacts occurs requiring weight and stiffness increases
Solution Approach 1:
The invention changes the fastening location from front or rear regions to lateral sides of the carriage body. This dimensional change in positioning allows the coupling to occur at the sides rather than ends, distributing impact forces more effectively and reducing deformation without requiring excessive weight or stiffness
