Foldable Bath Tub with Adjustable Backrest and Integrated Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable bath tubs are cumbersome for storage and do not accommodate the changing bathing positions of infants as they grow, from reclined to upright, and lack efficient drainage solutions.
Innovation Solution
A foldable bath tub design featuring a base, rim, and basin wall with circumferential creases that allow the basin wall to fold into itself, providing adjustable backrest angles and drainage holes for accommodating infants and toddlers, with a drain plug system for easy water removal without relocating the child.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a foldable bath tub is designed to be compact for storage, then storage space requirement is reduced, but the tub may not accommodate children in upright position
Solution Approach 1:
The bath tub incorporates a dynamic backrest assembly that can be adjusted between multiple positions (reclined, upright, and intermediate angles) to accommodate children's growing needs. The backrest is connected via hinges or pivot points, allowing it to be repositioned without requiring a completely different tub configuration, thus maintaining adaptability while keeping the tub compact for storage.
2Ease of manufacture
If the bath tub is designed with fixed structure, then manufacturing is simpler, but it cannot adapt to changing bathing needs as children grow
Solution Approach 1:
The bath tub is divided into separate functional segments: a base tub body and an adjustable backrest assembly. The backrest is a detachable or independently adjustable component that can be configured in multiple positions. This segmentation allows the main tub structure to remain simple for manufacturing, while the modular backrest provides the necessary adaptability for growing children.
3Productivity
If drainage holes are positioned at the bottom of the tub, then water drainage is effective, but the child must be relocated to drain the tub
Solution Approach 1:
The invention introduces an intermediary drainage mechanism in the form of a drain tube or channel that extends from the bottom drainage hole up to the backrest area. This tube allows water to be drained from the bottom (maintaining drainage efficiency) while the opening or control mechanism is positioned near the backrest, enabling parents to operate the drainage system without moving the child from their comfortable position.

AI summary
A foldable bath tub includes a base, a rim, and a basin wall disposed between and interconnecting the base and the rim. The bottom wall has an upwardly extending crotch support. The basin wall includes at least one crease. The basin wall is configured to be positioned in one of a folded condition in which the basin wall is folded into itself at the at least one crease an extended condition in which the basin wall is configured to receive an associated child. Where in the extended condition of the basin wall a distance from the base to the at least one crease increases along a length direction of the bath tub from a first end of the bath tub to a second end of the bath tub.
