Modular Hip Seat Carrier for Shoulder Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hip seat carrier systems apply excessive load on users' shoulders as infants grow and gain weight, and they lack flexibility to adapt to varying circumstances such as user strength, posture, and environment.
Innovation Solution
A hip seat carrier set that allows selective connection of a hip seat or carrier blanket to distribute the infant's weight, enabling mode changes based on user strength, posture, and environment through adjustable fastening mechanisms like zippers and Velcro.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional carrier blanket is used to carry an infant, then the infant can be held in the user's chest or on the back, but the weight of the infant is delivered to the user's shoulders causing strain and the user may have to lean forward or backward to keep balanced
Solution Approach 1:
The carrier system is divided into separate functional components: a carrier body for holding the infant and a waist band for supporting the weight. This segmentation allows the weight-bearing function to be separated from the infant-holding function, distributing the load to the user's waist and hips rather than concentrating it on the shoulders.
2Stress or pressure
If a hip seat is used to deliver weight to the user's waist, then the user can hold the infant easily, but the user must have one arm around the infant's back or abdomen for safety, restricting movement
Solution Approach 1:
The carrier incorporates dynamic adjustment mechanisms including adjustable shoulder straps and waist bands that can be modified based on the user's needs and the infant's weight. This allows the carrier to adapt from a more secure configuration to one that provides greater freedom of movement as conditions change.
3Ease of operation
If a product combining carrier blanket and hip seat is used, then the user can carry the infant with one hand free, but as the infant grows and gains weight, an excessively great load would be applied to user's shoulders
Solution Approach 1:
The carrier features adjustable parameters including the length and positioning of shoulder straps and waist bands. As the infant's weight increases, the user can adjust these parameters to redistribute the load more effectively, preventing excessive stress on the shoulders even as carrying conditions change over time.
4Device complexity
If a conventional hip seat or carrier blanket is used, then it provides a single mode of usage, but it is difficult for the user to use the product appropriately depending on varying circumstances
Solution Approach 1:
The carrier is designed with multiple functions within a single system: it can be used as a traditional carrier blanket, as a hip seat configuration, or with adjustable support levels. The same basic structure serves different carrying styles and accommodates various user needs and infant positions, providing versatility without requiring multiple separate products.

AI summary
A hip seat carrier set for use in holding an infant, comprising a carrier including a first supporting member capable of supporting an infant, and a shoulder band to be attached to the user's shoulders when the user puts on the carrier; hip seat separably coupled to the carrier, including a waist belt to be fastened around the user's waist, and for holding hips of the infant thereon; and a carrier blanket separably coupled to the carrier, and including a second supporting member capable of supporting the body of the infant, and a pelvis belt to be connected to a lower portion of the second supporting member and to be put on around the user's body to support the hips of the infant, wherein the hip seat or the carrier blanket is coupled to the carrier depending on a mode of usage, can be provided.
