Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Changing an infant's diaper is challenging due to the need to hold the infant's legs while managing active movements and potential mess, lacking efficient and safe assistance devices.
Innovation Solution
A diaper changing assistance device featuring an adjustable elongated rod with ringed members, a housing for supplies, a clear shield, light and audio mechanisms for distraction, and secure fasteners for comfort and ease of use, including hook and loop or snap clasp fasteners with a quick release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a parent holds the infant's legs manually during diaper changing, then the infant can be positioned for diaper application, but the parent cannot simultaneously manage active infant movements and apply the diaper efficiently
Solution Approach 1:
The patent introduces an intermediary device (the rod with ringed members) that acts as a mediator between the parent and the infant's legs. The ringed members secure around the infant's ankles, allowing the parent to control leg position without direct manual holding, thereby enabling simultaneous diaper application and reducing changing time.
Solution Approach 2:
The device enables the infant's legs to be self-positioned and self-secured through the ringed members that fasten around the ankles. Once the ringed members are secured, they automatically maintain leg position without requiring continuous parental intervention, allowing for more efficient diaper changing.
2Ease of operation
If the infant is held securely to prevent flailing legs, then diaper application becomes easier, but the infant's comfort and mobility are restricted
Solution Approach 1:
The device applies restraint only locally at the ankles through the ringed members, rather than restricting the entire body. The ringed members are padded to provide comfort specifically at the contact points, allowing the infant to move freely elsewhere while maintaining secure leg positioning for diaper application.
Solution Approach 2:
The ringed members are designed to be adjustable and flexible, allowing them to adapt to the infant's movements rather than imposing rigid constraints. The fasteners can be quickly adjusted or removed if the infant becomes uncomfortable, providing dynamic control over the level of restraint.
3Productivity
If the diaper changing process is made quick and efficient, then time is saved, but the risk of creating messes increases due to active infant movements
Solution Approach 1:
The ringed members are secured around the infant's ankles before the diaper changing process begins, establishing leg control in advance. This preliminary action prevents unexpected leg movements during diaper application, reducing the risk of messes while maintaining efficient changing speed.
4Adaptability or versatility
If the rod is made adjustable to fit any infant, then versatility is improved, but the device complexity increases
Solution Approach 1:
The rod incorporates adjustable elements that allow it to change length or configuration to accommodate different infant sizes. The adjustment mechanism is designed to be simple and intuitive, enabling parents to quickly adapt the rod to their specific infant without complex procedures.

AI summary
A diaper changing assistance device. The diaper changing assistance device provides efficiency to a parent changing a diaper of an infant. A rod is attached between an infant's ankles by a pair of ringed members. The rod can be freely lifted by the parent so that the parent is able to change the diaper of the infant with reducing flailing and movement of the infant.
