Adjustable Child Buggy Frame for Multi-Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child buggies are inflexible, unstable, particularly when carrying multiple infants or additional loads, and are not suitable for transporting infants of different sizes, with inadequate storage solutions that compromise stability and accessibility.
Innovation Solution
A child buggy with an adjustable frame and holders, allowing for the attachment of a second load next to the first load in both narrow and wide configurations, featuring a storage element that can be placed low and centrally to improve stability, and holders that can be adjusted for different infant sizes, along with a telescopic rod assembly and brake mechanism for enhanced durability and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame width is increased to accommodate multiple loads or infants, then the versatility and capacity of the child buggy is improved, but the stability and road holding deteriorate
Solution Approach 1:
The frame width is made dynamically adjustable between a first width optimized for single-load stability and a second width for multi-load capacity. This allows the buggy to adapt its geometry to match the actual loading conditions, achieving both stability when carrying one load and versatility when carrying multiple loads
2Adaptability or versatility
If additional loads are fastened to the push rod or upper frame areas, then the capacity to carry baggage is improved, but the stability and road holding are adversely influenced
Solution Approach 1:
Instead of placing additional loads in upper or rear positions that compromise stability, the invention provides fastening elements that enable baggage to be attached in lateral positions adjacent to the infant seat. This lateral arrangement maintains a lower center of gravity and better weight distribution, preserving stability while increasing carrying capacity
3Adaptability or versatility
If the frame is made telescopic to allow width adjustment, then the adaptability for different configurations is improved, but the structural robustness deteriorates
Solution Approach 1:
The telescopic mechanism allows the frame to dynamically adjust its width while maintaining structural integrity through properly engineered joint connections. The frame can be configured in distinct width positions that provide both adaptability for different usage scenarios and sufficient robustness for safe operation
4Device complexity
If the child buggy is designed for a single infant seat configuration, then the structural simplicity is maintained, but the versatility for different infant sizes and combinations deteriorates
Solution Approach 1:
The frame is designed with universal fastening elements that can accommodate various load configurations - a single infant seat, multiple infant seats in combination, or baggage attachments. This multi-functional capability allows the same basic structure to serve different purposes without requiring completely different designs for each scenario
