Solution Overview

Problem

There is a need for a medical device that provides mobility assistance to patients, allowing them to sit comfortably for both bathing and biological purposes, while being adaptable for use in showers and commodes, with adjustable seating and support features.

Innovation Solution

A sanitary chair with a coaxial aperture, adjustable telescopic legs, a base structure, seating cushions, a folding cushion, and a backrest, designed to be placed over a commode or bathtub, offering adjustable seating and support for patients, with components like telescopic legs and a U-shaped rail for easy movement and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed chair is used in bathroom, then patient can sit for bathing, but patient cannot use it for biological purposes with commode

Engineering Contradiction:

Improvedual functionality for bathing and commode useVSAvoidchair structure design

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The chair is designed with a universal base structure that can accommodate both bathtub and commode configurations. The base includes mounting mechanisms that allow the seat to be securely attached to either a bathtub rim or commode, enabling a single chair design to serve multiple functions for patient care

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If chair height is fixed, then manufacturing is simple, but patient comfort for different patients is compromised

Engineering Contradiction:

Improveseating comfortVSAvoidchair production

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The chair incorporates adjustable height legs that can be modified to suit different patient needs and bathroom configurations. The legs feature telescopic sections with locking mechanisms, allowing the overall chair height to be adjusted while maintaining structural integrity and ease of assembly

Inventive Principle:

Principle #15Dynamics

3Reliability

If chair is made stable and fixed, then patient safety is improved, but ease of movement and repositioning is reduced

Engineering Contradiction:

Improvepatient safetyVSAvoidchair repositioning

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The chair employs adjustable and removable components including the legs and seat assembly. The legs can be detached and reattached, and the seat can be removed for cleaning or repositioning, allowing the chair to transition between stable fixed positions for patient safety and movable configurations for ease of repositioning in the bathroom environment

Inventive Principle:

Principle #15Dynamics

AI summary

The sanitary chair forms a seat that is a configured for use in a shower and with a commode. A patient sits on a horizontal surface formed by the sanitary chair. One dimension of the horizontal surface is adjustable. The sanitary chair comprises a plurality of legs, a base structure, a rail, a seat cushion, a folding cushion, and a back rest. The base structure forms the horizontal seating surface of the sanitary chair. The plurality of legs raise the base structure above the supporting surface. The seat cushion and the folding cushion forms the horizontal seating surface of the supporting chair. The back rest is a vertically oriented structure that supports the back of the patient. The rail, the seating cushion, the folding cushion, and the back rest are attached to the base structure.
