Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diaper changing solutions, such as tables and mats, are either non-portable, unhygienic, and unsafe for use outside the home, and existing diaper bags lack a built-in changing surface, leading to inconvenience and safety hazards when changing a baby's diaper in public.
Innovation Solution
A convertible diaper bag that transforms into an elongated tray with elevated side walls and compartments, providing a padded and stable changing surface, while also organizing and securing baby supplies, ensuring hygiene and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional diaper changing table is used at home, then the baby has a clean and safe changing surface, but the table is not portable and cannot be taken outside the home
Solution Approach 1:
The patent combines a diaper bag with a changing table functionality into a single integrated unit. The bag contains all necessary changing supplies (diapers, wipes, creams) and transforms into a portable changing surface with raised sides to prevent baby from rolling off, eliminating the need to separate carrying supplies and providing a changing surface.
Solution Approach 2:
The diaper bag serves multiple functions: it stores all changing supplies, provides a portable changing surface when transformed, and can be carried on the parent's body. This multi-functional design replaces the need for both a stationary changing table and a separate supply bag.
2Ease of operation
If a folding changing table is used in public restrooms, then a changing surface is available, but the surface is hard plastic and not clean or comfortable for the baby
Solution Approach 1:
The patent employs a disposable or easily cleanable liner that can be placed inside the bag's changing surface. This liner provides a clean, comfortable, and hygienic barrier between the baby and the bag's interior, similar to how disposable changing pads are used on public tables, but with the advantage of being integrated into the parent's personal bag.
3Adaptability or versatility
If a flat portable changing mat is used outside the home, then the bag is portable, but the mat provides little comfort and the baby can easily roll off
Solution Approach 1:
The changing surface within the bag features raised curved sides that gently slope upward, creating a containment effect that prevents the baby from rolling off while maintaining a comfortable curved surface for the baby's body. This curvature provides both safety and comfort unlike flat mats.
4Quantity of substance
If conventional separate diaper bag and changing table are used, then supplies can be stored, but the adult must pack all items separately and may forget items
Solution Approach 1:
The patent merges the storage function and changing surface function into a single integrated bag. All changing supplies (diapers, wipes, creams, bottles) are stored within the bag, and the bag itself transforms into the changing surface, eliminating the need to pack and unpack separate items and reducing the risk of forgetting supplies.

AI summary
A method of using a convertible includes providing a convertible bag that includes a changing surface including a first tray panel and a second tray panel; first and second panel side walls extending perpendicular from the first and second tray panels, respectively; a shoulder strap including a first strap end and a second strap end, wherein each of the first and second strap ends is removably attached to the bag; and a plurality of connection points for removably attaching the first and second strap ends to the bag. The convertible bag moves between a closed position and an open position. In the closed position, the first panel and the second panel are parallel. In the open position, the first and second tray panels are within a plane.
