Height Adjustable Bathtub with Expandable Basin for Child Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional child bathtubs lack height adjustability and traction, leading to safety issues such as falls and injuries, especially in young children, as they often require lying or sitting, and adult supervision may not be sufficient to prevent quick accidents.
Innovation Solution
A height adjustable bathtub with an expandable basin and extendable legs that can pivot for stability, featuring a flexible intermediate wall and drainage system, along with a handlebar for support, designed to accommodate children of varying heights and provide enhanced safety features like quick drainage and storage options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional child bathtubs are designed with fixed low height for safety, then children can bathe safely, but parents experience back strain and cannot supervise effectively
Solution Approach 1:
The bathtub incorporates an extendable base with telescoping legs that can be adjusted to different height positions. This dynamic height adjustment allows the tub to be raised to a comfortable supervision height for parents while maintaining a safe bathing environment for children, resolving the contradiction between child safety and parental comfort.
2Adaptability or versatility
If child bathtubs are designed for lying or sitting positions, then infants can bathe comfortably, but older children cannot stand safely in the tub
Solution Approach 1:
The extendable base allows the bathtub to be raised to a height where older children can stand safely during bathing. The same base can be lowered for infants who need to lie or sit. This dynamic height adjustment provides adaptability for different age groups and bathing positions while maintaining safety for all users.
3Ease of manufacture
If child bathtubs lack height adjustability, then the structure is simple and inexpensive, but they cause back strain for parents and safety issues for children
Solution Approach 1:
The extendable base with telescoping legs adds height adjustability functionality while maintaining relative manufacturing simplicity. The base can be extended or retracted to adjust the bathtub height, providing safety and comfort benefits without requiring complex mechanisms or significantly increasing manufacturing complexity.

AI summary
A height adjustable bathtub includes a housing that extends from a first longitudinal end to a second longitudinal end and that extends from a first lateral end to a second lateral end. The housing has an interior wall that defines a cavity therein. An expandable basin is positioned within the cavity and is secured to the interior wall of the housing. An extendable base is secured to a bottom surface of the housing. The expandable basin includes a perimeter wall and a floor. The perimeter wall includes an upper wall portion that is secured to the interior wall of the housing, a bottom wall portion that is integrally formed with the floor, and a flexible intermediate wall portion that is secured to the upper wall portion and the bottom wall portion.
