Vented Walk-Through Door Windshield for Marine Cabin Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Marine vessels with closed cabins or covered cockpits face ventilation challenges due to carbon monoxide accumulation and inadequate airflow, posing safety risks for operators and occupants.
Innovation Solution
A windshield assembly with a vented walk-through door section that includes a pivotable door frame, a selectively vented door panel, and a latch mechanism, allowing for improved airflow and ventilation while maintaining structural integrity and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a closed cabin or covered cockpit is used, then structural integrity and protection are improved, but ventilation and carbon monoxide exhaust removal deteriorate
Solution Approach 1:
The windshield assembly is segmented into multiple sections including a first section, second section, and door section that can operate independently. The door section can be opened to create ventilation pathways while maintaining the structural integrity of the remaining windshield sections.
Solution Approach 2:
The door section is made pivotable between closed and open positions, allowing the structure to dynamically adapt between providing full enclosure for protection and creating ventilation openings for airflow, thus resolving the contradiction between closed structure and ventilation needs.
2Strength
If a closed cabin or covered cockpit is used, then protection from elements is improved, but airflow for cooling deteriorates
Solution Approach 1:
The windshield assembly is divided into separable sections with the door section being independently operable. This segmentation allows selective opening of the door section to create cooling airflow pathways while maintaining the protective enclosure of the main windshield structure.
Solution Approach 2:
The pivotable door section enables dynamic adjustment of the enclosure, allowing it to transition between a closed protective state and an open ventilation state, thereby providing both protection and cooling airflow as needed.
3Ease of operation
If a pass-through is provided in the windshield, then access to bow area is improved, but structural integrity deteriorates
Solution Approach 1:
The windshield assembly is segmented into a first section, second section, and door section. The door section serves as the pass-through element that can be independently opened for access to the bow area, while the first and second sections maintain the structural integrity of the windshield.
Solution Approach 2:
The pivotable door section provides a dynamic pass-through mechanism that can be opened for access when needed and closed to maintain structural integrity, allowing the structure to adapt between providing access and maintaining strength.

AI summary
A windshield assembly for a covered vessel includes a door section forming part of the windshield. The door section includes a door section securable to the vessel and being substantially contiguous with the windshield. The door section includes a door frame pivotable between a closed position and an open position, and a door panel mounted in the door frame. The door panel includes a selectively vented opening. The windshield assembly including the door section provides access to a bow area on a front side of the windshield and also improves air circulation, cooling and ventilation through the cabin.
