Solution Overview

Problem

Foldable bathtubs often lack sufficient strength, posing a safety risk when unfolded, and occupy significant space when stored.

Innovation Solution

A foldable bathtub design featuring a tub body, supporting members, a foldable portion, and reinforcing elements that enhance structural strength by covering side surfaces of the foldable portion, connected via snap-fitting or insertion, allowing easy assembly and disassembly for storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the bathtub is made foldable to facilitate storage, then the storage space requirement is reduced, but the strength and safety during use is compromised

Engineering Contradiction:
Improvestorage spaceVSAvoidstructural strength
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The bathtub is divided into multiple detachable sections including the tub body, supporting members, and reinforcing elements. This segmentation allows the bathtub to be folded and stored compactly while maintaining structural integrity during use through proper reassembly of the segmented components

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bathtub employs composite structural design combining the tub body, supporting members, and reinforcing elements made of different materials with complementary properties. The reinforcing elements are specifically designed with greater strength than the foldable portion to compensate for strength loss during folding while enabling compact storage

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If the bathtub size is increased to accommodate children, then the bathing comfort is improved, but the storage difficulty increases

Engineering Contradiction:
Improvebathing comfortVSAvoidstorage ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The bathtub transitions from a static rigid structure to a dynamic foldable structure. The supporting members and reinforcing elements are designed to be detachable and reconfigurable, allowing the bathtub to change its form factor from a large functional state during use to a compact stored state, thus resolving the contradiction between size and storage ease

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the bathtub is left exposed for easy access, then the convenience of use is improved, but the aesthetic appearance deteriorates

Engineering Contradiction:
Improveconvenience of useVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The detachable design allows the bathtub to be segmented into storage-ready components that can be neatly organized when not in use, improving aesthetic appearance while maintaining quick reassembly capability for convenient access when needed

Inventive Principle:
Principle #1Segmentation
