Mobile Low-Height Toilet for Elderly and Others

The mobile low-height toilet is an assistive device designed to address the toilet difficulties faced by groups such as the elderly, pregnant women, and post-operative rehabilitation patients. Its core function is to reduce the difficulty of sitting and standing up by optimizing height and structure, while also considering portability and safety.

Design Principles and Core Functions

This type of toilet is based on ergonomic principles, adjusting the seat height to shorten the distance for the "sitting-to-standing" transition and reducing the force required to stand up. For example, the HOUYA squat-to-sit toilet is designed with an optimized height, allowing the knee bending angle to be smaller than that of a regular toilet when sitting down. When standing up, only slight force is needed from the thighs and core muscles to complete the action, making it particularly suitable for the elderly with insufficient waist and abdominal strength. Its flip-top design prevents odors and is easy to clean, with some models supporting the use of garbage bags to further simplify the cleaning process.

Key Selection Criteria

1. Stability and Safety: Prioritize models with a thickened steel tube frame structure and anti-slip foot pads at the bottom to prevent sliding or tipping during use. For example, a four-leg support design is more stable than a two-leg design, suitable for users with a larger body weight or poor balance.
2. Height Adaptability: The seat height should meet the natural bending needs of the human body, with the knee joint bent at 90°-110° when sitting down, allowing the front thigh muscles to exert force easily when standing up. Too high or too low a height will increase the difficulty of standing up and may even cause excessive pressure on the waist.
3. Portability and Storage: Models with folding functionality can save space and are suitable for small apartments or scenarios requiring frequent movement. The folded thickness is recommended to be no more than 15cm for easy storage under beds or in corners.
4. Material and Cleaning: The surface material should be waterproof and stain-resistant, with priority given to PP plastic or ABS material to prevent rusting of metal parts. A detachable seat ring design facilitates thorough cleaning and reduces bacterial growth.

Usage Scenarios and Advantages

This device can be used directly on squat toilets or the ground without modifying the existing bathroom layout, making it suitable for rental properties, old residential areas, and other environments where renovation is inconvenient. Its portability also makes it convenient for short-term use by post-operative rehabilitation patients or as a temporary assistive tool in case of sudden mobility difficulties. Compared to fixed toilets, low-height toilets are lighter and generally have a lower price, offering significant cost-effectiveness.
