Easily modified bathing chair

Solution Overview

Problem

Conventional sliding bathing chairs require additional space to span the bathtub and lack the ability to be easily converted between fixed and sliding types, leading to increased user burden and storage inconvenience, as well as higher costs due to the need for separate purchases of fixed and sliding models.

Innovation Solution

The design incorporates two side connecting pedestals with beam tubes and legs, a seat with slides, and interchangeable long and short upper beam sets, allowing the seat to be easily converted between sliding and fixed modes by adjusting the beam tubes' position relative to the slides, thereby eliminating the need for separate chairs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a sliding bathing chair is designed to span the bathtub, then it can assist users to get in and out of the bathtub, but the width of the chair is extended and requires separate purchase of a fixed bathing chair

Engineering Contradiction:

Improvebathing chair functionalityVSAvoidchair width

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a convertible bathing chair where the upper beam can be adjusted between two positions: extended outward to enable sliding function across the bathtub, and retracted inward to create a compact fixed chair configuration. This dynamic adjustment allows the same chair structure to provide both sliding and fixed bathing functions, eliminating the need for separate chairs and reducing storage requirements

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a sliding bathing chair is designed, then it can help users get in and out of the bathtub, but users need to purchase a fixed bathing chair separately which is an extra burden

Engineering Contradiction:

Improvebathing chair functionalityVSAvoidnumber of chairs

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent designs a universal bathing chair that integrates both sliding and fixed functions into a single device. By incorporating an adjustable upper beam mechanism, the chair can transform between configurations to serve different bathing needs, allowing one chair to replace what would traditionally require two separate chairs, thereby reducing the quantity of equipment users need to purchase and store

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a sliding bathing chair is designed, then it can assist users to bathe, but it is inconvenient for storing

Engineering Contradiction:

Improvebathing chair functionalityVSAvoidstorage space

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent implements a convertible bathing chair where the upper beam can be adjusted between two positions: extended outward to enable sliding function across the bathtub, and retracted inward to create a compact fixed chair configuration. This dynamic adjustment allows the same chair structure to provide both sliding and fixed bathing functions, eliminating the need for separate chairs and reducing storage requirements

AI summary

An easily modified bathing chair comprises: two side connecting pedestals, having a beam, two beam tubes and two leg tubes respectively; four legs which are fixed in the leg tubes of the two side connecting pedestals, respectively; a seat, having two front slides and two rear slides on a bottom thereof, wherein the two front slides each have a first seat positioning structure; and a long upper beam set and a short upper beam set, wherein either the long upper beam set or the short upper beam set is slidingly mounted on the seat and set between the beam tubes of the two side connecting pedestals, thereby it is achieved that a bathing chair of any of two types is assembled conveniently.
