Vacuum-Assisted Toilet Noise Reduction System ID: 2018-012

A novel invention designed to significantly reduce noise in vacuum-assisted toilets while optimizing water usage.

Technology Overview

This technology introduces a continuous and variable mass-flow rinse system for vacuum-assisted toilets, commonly used in aircraft and cruise ships. Unlike traditional designs that inject rinse water at constant pressure, this invention allows for dynamic adjustment of both the timing and mass flow rate of the rinse water, aiming to mitigate noise more effectively throughout the flushing cycle. The system's operation is managed through software that synchronizes the flush and rinse valves, incorporating sensors to analyze waste composition and dynamically adjust the rinse accordingly.

Key Advantages

• Enhanced noise reduction throughout the entire flush cycle
• Optimized water usage by dynamically compensating for the waste volume present before flushing
• Ability to adjust the mass flow during rinse to minimize water use while maintaining noise reduction
• Improved environmental impact through efficient water management

Problems Addressed

• Excessive noise generated by vacuum-assisted toilets, particularly in confined environments like aircraft and cruise ships
• Inefficient water usage in traditional toilet flushing systems
• Lack of adaptability in rinse water flow and pressure based on waste volume and composition

Market Applications

• Aviation industry for noise reduction in aircraft lavatories
• Maritime industry, specifically in cruise ships, for enhanced passenger comfort and environmental compliance
• Any sector utilizing vacuum-assisted sanitary systems seeking to improve environmental efficiency and user experience
