Vertical bathtub closure systems and methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bathtubs pose a barrier for individuals with mobility issues due to their high sidewalls, making it difficult for them to access the water safely and efficiently, and existing solutions either require costly renovations or compromise on water retention.
Innovation Solution
A bathtub closure system featuring a hinged plug and modular step system that allows for easy access and egress while maintaining water retention, with a plug that can be lifted vertically to transition between open and closed positions, and is adaptable to various barrier types and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional bathtub with high sidewalls is used, then water retention is maintained, but accessibility for individuals with mobility issues deteriorates
Solution Approach 1:
The bathtub system is segmented into multiple functional components: a fixed tub structure, a removable insert with lowered sidewalls for accessibility, and a closure system. This allows the tub to serve dual purposes - providing easy access when the insert is in place, and maintaining water retention when the insert and closure are used together
Solution Approach 2:
The closure system incorporates a hinge mechanism that allows the closure panel to dynamically transition between open and closed positions. This dynamic element enables the system to adapt between accessibility mode (open) and water retention mode (closed), resolving the contradiction between these two requirements
2Ease of operation
If the bathtub is removed and replaced with a shower system, then accessibility is improved, but cost and complexity of renovation increase
Solution Approach 1:
The insert is designed as a universal component that can be installed in standard bathtubs without requiring removal of the original tub or installation of complex shower systems. It provides shower-like accessibility while maintaining compatibility with existing bathtub infrastructure
Solution Approach 2:
The insert and closure system represent a cost-effective, removable solution compared to permanent bathtub replacement. The components can be installed and removed without professional renovation, making them an economical alternative to full shower system installation
3Ease of operation
If a lowered sidewall insert is added to improve accessibility, then ease of access is improved, but water retention capability deteriorates
Solution Approach 1:
The system separates the accessibility function (lowered sidewall insert) from the water retention function (closure system with high walls). The insert provides easy access while the removable closure panel restores the high barrier needed for water retention when the tub is in use
4Ease of operation
If a hinged closure system is used, then accessibility is improved through easy opening, but device complexity increases
Solution Approach 1:
The hinge mechanism is designed to be self-contained and self-operating, requiring no external power source, motors, or complex control systems. The user simply pulls the closure panel open or closes it manually, and the hinge provides the necessary mechanical support without adding system complexity

AI summary
Embodiments described herein include a bathtub closure system having a step, the step having a first side panel, a second side panel, and an elongated platform defining a cavity, where the cavity can be configured to facilitate ingress and egress into a bathtub. The bathtub closure system can include a hinged closure, where the closure can be coupled with the step and can cooperate with the step to form a substantially watertight seal when the closure is in a closed position.
