Yu Kaisheng Invented Portable Toilet

Yu Kaisheng did not invent mobile toilets; instead, he invented a portable toilet and obtained a national utility model patent certification. Here are the details:

I. Inventor and Patent Certification
Yu Kaisheng, a resident of the Kaili Highway Bureau community, is the inventor of this portable toilet. His design has passed the review of the National Intellectual Property Administration and has been granted a utility model patent certificate. This certification indicates that the invention meets national standards in terms of structural innovation and practicality, and it enjoys legally protected technological rights and interests.

II. Core Design Features of the Portable Toilet

1. Morphological Variability
   The main body of the invention is a light green foldable structure. Demonstration videos show that its initial form is a small handbag, which unfolds to form a bucket-shaped space. This design is achieved through mechanical folding or elastic materials, ensuring portability during storage (with the volume reduced to a 'pancake' shape) and stability during use.

2. Human Body Adaptation Function
   The bucket-shaped structure can be directly placed over the human body, with its internal space designed to accommodate both excretion and changing clothes. By reasonably dividing the space or using adjustable support structures, users can complete defecation and clothing changes while standing, making it particularly suitable for outdoor emergencies or scenarios involving individuals with mobility issues.

3. Safety Protection Mechanism
   To address the risk of suffocation in confined spaces, the invention incorporates a ventilation device. This device may include a one-way exhaust valve or a miniature ventilation fan, maintaining internal oxygen concentration through continuous air circulation while preventing odor leakage.

III. Operation Process and Scenario Applications
Before use, the user takes the folded piece out of the bag and unfolds it; after use, it is restored to a flat state by compression or curling. This design makes it suitable for scenarios without fixed sanitation facilities, such as natural disaster relief, wilderness exploration, and temporary medical stations, effectively solving short-term toilet problems.

IV. Technological Value and Social Significance
This invention integrates the functions of traditional toilets into a portable device through structural innovation, filling a market gap for small-scale personal hygiene devices. Its patent certification not only protects the inventor's rights and interests but also provides technical references for the development of subsequent similar products, demonstrating the potential of civilian technology in improving quality of life.
