Angled Breathing Pipe Assembly for Mouthpiece Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breathing pipe assemblies for snorkeling and free diving cause discomfort due to the mouthpiece being tilted relative to the user's mouth, increasing muscle load and reducing enjoyment and duration of water activities.
Innovation Solution
The breathing pipe assembly features an inflexible design with a pre-formed angle between the mouthpiece and the central axis, allowing the mouthpiece to align with the user's mouth, reducing tilting and enhancing comfort during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mouthpiece is fixedly connected to the breathing pipe with lateral alignment, then the structure is simple and easy to manufacture, but the mouthpiece becomes tilted relative to the user's mouth when mounted on the head strap, causing discomfort and increasing muscle load
Solution Approach 1:
The mouthpiece is designed with an asymmetric angular orientation relative to the breathing pipe axis. The mouthpiece forms a specific angle (e.g., 15-45 degrees) with the central axis of the breathing pipe, creating an asymmetric configuration that compensates for the tilting effect when the breathing pipe is mounted on the head strap at different positions (left-high or right-low). This asymmetric design ensures the mouthpiece remains aligned with the user's mouth regardless of mounting position.
2Adaptability or versatility
If the breathing pipe is mounted in different positions on the head strap, then the device adapts to user preferences, but the mouthpiece tilting angle increases, worsening comfort and alignment
Solution Approach 1:
The mouthpiece is pre-formed at a specific angular orientation relative to the breathing pipe during manufacturing. This preliminary angular configuration is designed to counteract the expected tilting effect when the breathing pipe is mounted on the head strap. By pre-establishing this angular relationship, the system automatically compensates for mounting position variations without requiring user adjustment, maintaining optimal mouthpiece alignment across different mounting configurations.

AI summary
A breathing pipe assembly is provided, which includes a mouthpiece and an inflexible breathing pipe. The mouthpiece is fixedly connected to the lower portion of the inflexible breathing pipe. The inflexible breathing pipe is defined with a central axis extending along a longitudinal direction thereof, and the mouthpiece is defined with a transverse line connecting a left side and a right side thereof. The transverse line forms an angle relative to the central axis, and the angle ranges between 3° and 70°.
