Solution Overview

Problem

Users with motor disabilities or elderly individuals face challenges accessing and using traditional bathtubs without access doors, as they must wait uncomfortably for the bathtub to fill with water before entering, compromising safety and comfort.

Innovation Solution

A bathtub with a mobile partition that divides the main compartment into two semi-compartments, featuring an outflow valve that can be manually operated to allow water to flow between them, enabling faster filling and safer access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a bathtub is designed without an access door for traditional use, then the structure is simpler and more traditional, but users with motor disabilities or elderly individuals cannot safely access the bathtub

Engineering Contradiction:
Improveaccessibility for users with motor disabilitiesVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bathtub is segmented into two separate compartments by a mobile partition, allowing independent access to each compartment. This segmentation enables users with motor disabilities to access the bathtub safely through the access door while maintaining traditional bathtub functionality in the other compartment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mobile partition can be moved between compartments or removed entirely, dynamically adapting the bathtub configuration. This dynamic element allows the access door to be positioned in the most convenient location while maintaining structural flexibility and simplicity.

Inventive Principle:
Principle #15Dynamics

2Loss of time

If the bathtub is filled with water before the user enters, then the user can enter immediately, but water may leak out of the access door during filling

Engineering Contradiction:
Improvewaiting time for bathtub fillingVSAvoidwater leakage
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

By dividing the bathtub into two compartments with the mobile partition, the system allows one compartment to be filled with water while the other remains dry for user entry. This segmentation prevents water leakage issues while eliminating waiting time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows preliminary filling of one compartment before the user enters the other compartment. This preliminary action ensures water is ready when needed while preventing leakage during the filling process by isolating it from the access door area.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the user enters the bathtub before it is filled with water, then access is immediate and safe, but the user must wait uncomfortably for several minutes for the bathtub to fill

Engineering Contradiction:
Improveease of accessVSAvoidwaiting time for water filling
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The bathtub is divided into two compartments, allowing the user to enter one compartment immediately while water fills the other compartment separately. This eliminates the uncomfortable waiting period while maintaining immediate access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mobile partition acts as an intermediary element that separates the water-filling process from the user-entry process. This allows both actions to occur simultaneously without interference, eliminating waiting time while maintaining ease of access.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If an access door is added to the bathtub, then users with motor disabilities can access safely, but the bathtub structure becomes more complex and requires additional components

Engineering Contradiction:
Improvesafe access for users with limited motor skillsVSAvoidbathtub structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The access door is integrated as part of the mobile partition system that segments the bathtub into two compartments. This integration allows safe access for users with motor disabilities while managing structural complexity through a unified design approach.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mobile partition with integrated access door serves multiple functions: it provides safe access for users with disabilities, divides the bathtub into separate compartments, and can be repositioned or removed as needed. This multi-functionality reduces overall system complexity by combining multiple features into a single element.

Inventive Principle:
Principle #6Universality (Multi-functionality)
