Swivel Commode Chair with Rotatable Base for Independent Bedside Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with mobility issues, such as those with short-term or long-term injuries or the elderly, face challenges in independently using existing bed pans or catheters for excreting human waste, as these methods are often humiliating and require assistance, and there is a need for a device that allows for sitting and expelling waste into a bucket on a chair.
Innovation Solution
A swivel commode chair with a base, rotatably connected to a stationary frame, featuring elongated members and a removable bucket, where a person can sit and deposit waste through an opening in the base into a bucket that is slidably engaged with the chair, allowing for comfortable and independent use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bed pan is used for bedridden patients, then human waste can be collected, but the patient requires assistance from a nurse or other person which causes embarrassment and humiliation
Solution Approach 1:
The commode device is divided into separate functional components: a base portion with opening, a removable bucket for waste collection, and a cover portion. This segmentation allows the patient to independently manage the device while maintaining simplicity. The bucket can be removed and replaced without assistance, and the cover can be independently positioned.
Solution Approach 2:
The device enables self-service through features like the self-contained bucket that collects waste directly beneath the opening, the independent cover that can be positioned by the patient, and the overall design that allows the patient to use the device without requiring a nurse to hold or manage components during usage.
2Adaptability or versatility
If a standard bathroom toilet is used, then proper sanitation is achieved, but patients with mobility issues cannot travel to the bathroom
Solution Approach 1:
The commode device serves multiple functions: it can be used by bedridden patients, patients with mobility issues who can sit, and potentially as an additional commode in bathrooms. The base portion with opening and bucket configuration allows it to function as a portable toilet solution adaptable to various mobility levels while maintaining ease of operation through its simple design.
Solution Approach 2:
The device transitions the toilet function from a fixed location (standard bathroom) to a movable, portable format that can be positioned at the patient's bedside or in accessible locations. This dimensional change from fixed to mobile enables patients with mobility limitations to access toilet facilities without traveling to a standard bathroom.
3Ease of operation
If catheters are used for urination while in bed, then urination is facilitated, but excrement expulsion remains problematic
Solution Approach 1:
The device copies the essential function of a standard toilet (sitting position with opening for waste expulsion) in a simplified, portable format. The base with opening and bucket configuration replicates the toilet experience without requiring the complex plumbing and fixed installation of a standard bathroom toilet, making excrement expulsion as easy as using a regular toilet while maintaining simplicity.
