Solution Overview

Problem

Conventional infant towels fail to envelop and dry infants comfortably during and after bathing, often leaving caretakers' clothing wet and the process cumbersome due to the inability to completely wrap the infant.

Innovation Solution

An infant drying bag with two layers of the same size and shape, joined along three edges to form a cavity, featuring an opening for easy access and a head portion to accommodate the infant's head, allowing for secure and efficient drying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional towel is used to dry an infant, then the towel can be easily applied, but the infant cannot be completely wrapped and secured, causing the caretaker's clothing to become wet

Engineering Contradiction:
Improveease of applicationVSAvoidability to completely wrap and secure infant
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The drying bag is divided into two separate layers (first layer and second layer) that are joined along three edges, creating a semi-enclosed structure. This segmentation allows the bag to wrap around and secure the infant more effectively than a single flat towel, preventing the infant from slipping out while keeping the caretaker's clothing dry.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a two-dimensional flat towel to a three-dimensional bag structure by joining two layers along three edges, creating a cavity space. This dimensional change enables the bag to envelop and secure the infant's body more comprehensively, solving the problem of incomplete wrapping.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If a conventional towel is used to dry an infant, then the drying process can begin immediately, but the transition from bathtub to towel coverage is cumbersome

Engineering Contradiction:
Improvedrying efficiencyVSAvoidtime for transition from bathtub to towel coverage
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The drying bag is designed with an opening that allows the infant to be placed inside in a single motion, and the two layers can be quickly brought together to enclose the infant. This preliminary design of the opening and layered structure enables rapid transition from bathtub to drying position, reducing the time loss associated with maneuvering a conventional towel.

Inventive Principle:
Principle #10Preliminary action

3Object-affected harmful factors

If a conventional towel is used, then the towel material can be soft and absorbent, but the towel cannot provide a secure enclosure for the infant

Engineering Contradiction:
Improveinfant comfort during dryingVSAvoidstructure to provide enclosure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The drying bag utilizes two flexible layers of absorbent material that can be joined along three edges to form a soft, pliable enclosure. This flexible shell structure provides secure containment for the infant while maintaining comfort through the softness and absorbency of the material, without requiring rigid or complex structural elements.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

An infant drying bag configured to receive an infant therein so as to assist in the drying of an infant subsequent a bath. The infant drying bag includes a body wherein the body is formed from a first layer and a second layer. The body is rectangular in shape having a first longitudinal edge and a second longitudinal edge on opposing sides of the body. Proximate the lower end of the body is a lower peripheral edge. The first layer and second layer are joined along the first longitudinal edge, second longitudinal edge and the lower peripheral edge so as to form a cavity intermediate the first layer and second layer. The cavity is equivalent in size to the body and an opening is formed proximate the upper end of the body providing access to the cavity. The opening is defined by upper peripheral edges.
