Child carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child carriers often fail to provide a flexible and comfortable solution for carrying children of different sizes, as they typically have fixed space configurations that do not adapt well to varying child sizes and positions.
Innovation Solution
A child carrier design featuring a carrying harness with a child supporting part that includes a torso support portion and a neck support portion detachably connected via a fastener, allowing for adjustable vertical positioning of the neck support, along with a bib to cover the neck support portion and an expandable part to adjust the distance between the torso support and the carrying harness, ensuring comfortable support for children of different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed space configuration is used for seating a child, then the structure is simple and easy to manufacture, but it cannot adapt to children of different sizes and positions
Solution Approach 1:
The child carrier is divided into multiple independent support portions including a head support portion, a neck support portion, a torso support portion, and a hip support portion. Each portion can be independently adjusted or repositioned to accommodate children of different sizes and carrying positions, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The patent implements adjustable and repositionable support portions that can dynamically adapt to different carrying needs. The neck support portion can be repositioned relative to the torso support portion, and various components have adjustable lengths and positions, enabling the structure to transform from static to dynamic configuration.
2Ease of operation
If the neck support portion is detachably connected via a fastener, then the flexibility and convenience are improved, but the device complexity increases
Solution Approach 1:
The detachable connection between the neck support portion and torso support portion via a fastener divides the carrier into separable modules. This segmentation allows the neck support to be independently adjusted, removed, or repositioned, improving ease of operation while maintaining reasonable structural organization.
Solution Approach 2:
The fastener serves multiple functions: it connects the neck support portion to the torso support portion, allows for easy detachment and reattachment, and enables adjustment of the neck support position. This multi-functionality improves convenience without proportionally increasing complexity.
3Adaptability or versatility
If the neck support portion is foldable over the torso support portion, then the adaptability to different positions is improved, but the structural complexity increases
Solution Approach 1:
The foldable neck support portion enables dynamic adjustment between different vertical positions relative to the torso support portion. This dynamic capability allows the carrier to adapt to various carrying positions (front carry, back carry, side carry) without requiring complex mechanical mechanisms, as the folding action itself provides the necessary adjustability.
4Manufacturing precision
If multiple fastening parts are provided to hold the neck support and bib, then the support precision and comfort are improved, but the device complexity increases
Solution Approach 1:
Multiple fastening parts are strategically positioned to serve different functions: securing the neck support portion to the torso support portion, attaching the bib, and adjusting the fit. These fastening parts, while increasing component count, provide precise positioning capabilities and multiple attachment options that improve overall support precision and comfort.
