Detachable Child Carrier Leg Assembly for Easy Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child carriers with multiple usage modes have complex structures, making them not user-friendly for caregivers to easily switch between different modes to accommodate children of various ages and activities.
Innovation Solution
A child carrier design featuring a booster seat with a detachable leg assembly, allowing caregivers to adjust the height by detaching lower or upper supports, and optionally installing/removing a seatback, tray, and leg rest to provide different features across high chair, youth chair, and booster modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional child carriers are designed with multiple usage modes to accommodate children of different ages, then the adaptability is improved, but the device complexity increases making them not user-friendly
Solution Approach 1:
The child carrier is divided into separable components including a base unit and a leg assembly that can be detached. The leg assembly includes upper and lower legs that can be independently removed, creating distinct functional segments that simplify the overall structure while maintaining multiple usage configurations.
Solution Approach 2:
The child carrier features dynamically adjustable components where the leg assembly can be attached or detached based on usage needs. This dynamic reconfiguration allows the same base unit to serve multiple purposes (stroller mode, carrier mode, booster mode) without requiring a complex fixed structure for all configurations.
2Adaptability or versatility
If conventional child carriers include multiple detachable components for different modes, then the versatility is improved, but the ease of operation deteriorates due to complex assembly and disassembly procedures
Solution Approach 1:
The leg assembly is segmented into upper and lower legs that can be independently detached from the base unit. This segmentation simplifies the disassembly process compared to removing entire rigid assemblies, making mode switching more manageable and less complex for users.
Solution Approach 2:
The leg assembly is pre-configured with connection points and attachment mechanisms that align with corresponding features on the base unit. This preliminary design of connection interfaces enables straightforward attachment and detachment without requiring complex alignment procedures or multiple adjustment steps.
