Noise-Reducing Pipe Insert for Vacuum-Assisted Toilets ID: 2018-013

An innovative solution to significantly reduce noise in vacuum-assisted toilets used in aircraft and cruise ships.

Technology Overview

This invention introduces a pipe insert designed to reduce noise in vacuum-assisted toilets without increasing the toilet's footprint. By eliminating sharp flow redirections near the toilet bowl and extending the valve-to-bowl distance, the insert achieves noise reduction efficiently. Unlike other methods that rely on complex valve mechanisms or electronic controls, this solution is straightforward, involves no moving parts, and can be easily implemented in new designs or as retrofits.

Key Advantages

• Significant noise reduction in vacuum-assisted toilets
• Simple, no-moving-parts design for easy implementation
• Compatible with new toilet designs and existing system retrofits
• Does not increase the toilet's footprint

Problems Addressed

• Excessive noise from vacuum-assisted toilets in aircraft and cruise ships
• Complexity and cost of other noise-reduction methods
• Difficulty retrofitting existing systems with noise-reducing technology

Market Applications

• Aerospace industry for aircraft lavatories
• Marine industry for cruise ship restrooms
• Manufacturers looking for simple, effective noise-reduction solutions
• Retrofitting existing vacuum-assisted toilet systems
