Back Child Carrier Harness With Standing Platform Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional piggy-back rides are difficult to maintain over prolonged periods due to cut-off blood circulation, arm and leg fatigue, and size and strength limitations of both the child and the carrier, leading to discomfort and potential choking.
Innovation Solution
A child carrier with a shoulder harness, adjustable loops, handholds, a semi-rigid elongated platform, and flexible straps that distribute the child's weight, allowing for adjustable fit and comfort, along with optional stirrups and a tether for improved support and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional piggy-back ride is used to carry a child, then the child can be transported without additional equipment, but the carrier experiences cut-off blood circulation, arm fatigue, and leg fatigue due to the child's weight bearing down on the arms
Solution Approach 1:
The patent introduces a child carrier device as an intermediary between the child and the carrier's body. The device includes a platform that supports the child's weight and straps that distribute this weight across the carrier's shoulders and torso, preventing the arms from bearing the full load and thus eliminating blood circulation cut-off and arm fatigue
Solution Approach 2:
The child carrier device segments the weight-bearing function from the arm-holding function. The platform and strap system handles weight distribution, while the handholds provide secure positioning. This segmentation allows the arms to remain relaxed rather than continuously supporting the child's weight
2Device complexity
If the child's arms are draped over the carrier's shoulders to maintain position, then the child can be secured without additional equipment, but the child experiences arm fatigue and the carrier risks choking when the child's arms encircle the neck
Solution Approach 1:
The child carrier device acts as an intermediary that provides secure positioning through handholds and strap systems, eliminating the need for the child's arms to encircle the carrier's neck. This removes the choking risk and arm fatigue while maintaining secure positioning
Solution Approach 2:
The device extracts the positioning function from the child's arms. The handholds and strap system handle the securing function, allowing the child's arms to be free rather than bearing the burden of maintaining position
3Duration of action of moving object
If the carrier's arms continuously support the child's weight without rest, then the child can be carried for extended periods, but the carrier's arms experience fatigue due to sustained muscle engagement
Solution Approach 1:
The child carrier device serves as an intermediary that assumes the weight-bearing function through its platform and strap system. This relieves the carrier's arms from continuous weight support, eliminating muscle fatigue while enabling extended carrying duration through comfortable shoulder and torso distribution of the load
4Adaptability or versatility
If a piggy-back ride is used without accommodation for different sizes, then the device can be used universally without adjustment, but the ability to provide a comfortable and sustainable ride depends on the physical attributes of both the child and the carrier
Solution Approach 1:
The child carrier device incorporates adjustable straps and flexible components that can be dynamically configured to accommodate different child and carrier sizes. The strap length and positioning can be adjusted to ensure proper fit and weight distribution regardless of the physical attributes of the users
Solution Approach 2:
The device is designed with universal applicability through adjustable features that adapt to various size combinations. The platform, straps, and handholds can be configured to work with different child sizes and carrier physiques, making the device universally usable while maintaining comfort and sustainability

AI summary
A child carrier for carrying a child in a standing position on the back of the wearer is disclosed. The child carrier may have a shoulder harness having a first loop of material adapted to encircle a left shoulder area of a child carrier wearer, and a second loop of material adapted to encircle a right shoulder area of the wearer. The first loop of material and the second loop of material may be connected in an upper back region of the wearer. First and second handholds may be provided at the shoulder area of the first and second loops of material. The child carrier may have positions to attach accessories such as a water bottle, small enclosure for storage, and the like. In a first embodiment, a rigid or semi-rigid elongated platform having a width adapted to permit a child to stand on the platform may be suspended from the back of the shoulder harness by flexible straps, where the platform may be compact folding to allow the entire child carrier to be stored in a small pouch. In a second embodiment, individual stirrups for the child's feet may be suspended from the back of the shoulder harness.
