Boat Windshield Air Scoop for Water and Noise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boat windshield ventilation systems allow water splashes and generate whistling noise due to the design of openings, which detract from the user experience by allowing water intrusion and increasing noise as boat speed increases.
Innovation Solution
A ventilation system with an air scoop at the lower edge of the windshield directs wind through an upwardly inclined conduit to prevent water entry and reduce noise, featuring a hingeable vent and flaps that can be used to control airflow and maintain aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If openings are provided in the windshield to allow wind entry, then ventilation is improved, but water splashes enter the pilot station
Solution Approach 1:
The air scoop is positioned at the lower edge of the windshield and directs airflow upward through a vertically oriented conduit. This dimensional change from horizontal to vertical airflow prevents water splashes from entering while maintaining ventilation, as water naturally falls downward due to gravity while air rises through the conduit.
Solution Approach 2:
The upwardly inclined conduit acts as an intermediary structure between the external air scoop and the internal ventilation opening. This intermediary channel separates the air flow path from potential water intrusion paths, allowing air to pass through while blocking water from reaching the pilot station.
2Ease of operation
If openings are provided in the windshield to allow wind entry, then ventilation is improved, but whistling noise increases
Solution Approach 1:
The conduit is designed with an upward inclination rather than a horizontal opening. This angular change disrupts the direct airflow path that causes whistling noise, while still allowing effective air intake and ventilation to the pilot station.
3Object-affected harmful factors
If the air scoop is positioned at the lower edge of the windshield, then water entry is prevented, but the structure becomes more complex
Solution Approach 1:
The air scoop, conduit, and ventilation system are integrated into a single unified structure at the lower edge of the windshield. This merging of components achieves water protection and ventilation functions simultaneously without requiring separate complex systems, thereby minimizing overall structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents water from entering the pilot station and significantly reduces noise, enhancing the user experience by allowing wind penetration while maintaining protection from strong winds and water splashes.
Implementation Method 1
an air scoop provided at an outside surface of the windshield for scooping air produced by the forward motion of the boat. The air scoop may be shaped and dimensioned to allow the air scooped by it to circulate upward in a conduit
Implementation Method 2
This configuration removes water drizzles from the wind as it moves upward
Implementation Method 3
reduces/eliminates the noise that the wind makes when being scooped and directed toward the air outlet

AI summary
There is described a ventilation system for a boat. The windshield body comprises an air scoop in a bottom portion of the windshield body, facing a forward direction of the boat for air entry, the air scoop having an entry which is substantially horizontal and the air scoop extending upwardly within the windshield body to form a conduit having an upward component. The conduit end opens toward an inside of the boat, at a location higher than the entry of the air scoop. A hingeable vent can be installed on the opening inside the boat to be open or closed. The vent may also be sued with a direct opening with the outside. In this case, flaps can be installed in the opening. The flaps can be hingeable about their own respective hinge axis, and move together using a solid link. The flaps may be used without the vent.
