Marine Windshield Transition Members for Sharp Deck Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Marine windshields face challenges in bending glass at sharper angles without distortion, as existing methods struggle to accommodate sharp deck shapes and maintain a clear view, and bending glass beyond a certain point can lead to undesirable view distortion.
Innovation Solution
The introduction of transition members with adjustable radii that adapt the windshield sections to fit sharper deck profiles, allowing the glass to cut across corners and reducing the curve amount, while also providing additional functionality such as accent lighting and storage options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If glass is bent at sharper angles to accommodate deck shapes, then the transition between sections is smoother and appearance is improved, but view distortion occurs and manufacturing becomes difficult
Solution Approach 1:
The windshield is divided into multiple sections (side sections and center section) that can be manufactured separately with different curvature radii. The side sections use a first curvature radius while the center section uses a second curvature radius, allowing each section to be optimized for its specific geometric requirements without forcing the entire glass structure to conform to a single bend radius.
Solution Approach 2:
Different portions of the windshield glass are assigned different curvature characteristics. The side sections incorporate a first curvature radius that accommodates sharp deck angles, while the center section incorporates a second curvature radius that maintains clearer viewing characteristics. This local differentiation allows the glass to adapt its shape properties to specific functional and aesthetic requirements.
2Adaptability or versatility
If glass is bent beyond a certain point to fit sharp deck profiles, then the deck shape accommodation is improved, but view distortion becomes undesirable
Solution Approach 1:
The windshield structure is segmented into side sections and a center section, allowing each segment to be bent to different degrees. The side sections can accommodate sharp deck profiles with larger curvature radii, while the center section maintains smaller curvature radii to preserve view clarity, thus resolving the conflict between adaptability and reliability.
Solution Approach 2:
The curvature radius parameter is varied across different sections of the windshield. By changing the curvature radius from the side sections to the center section, the design optimizes both deck profile accommodation and view clarity. This parameter differentiation allows the glass to adapt to sharp deck angles while maintaining acceptable viewing characteristics in the center area.
3Manufacturing precision
If side sections are manufactured and installed separately from front sections to accommodate turn angles, then glass bending is avoided, but the overall structure becomes more complex
Solution Approach 1:
The windshield is divided into side sections and a center section that can be manufactured separately. This segmentation allows each section to be fabricated with appropriate curvature radii without requiring complex bending operations, while the modular design simplifies the overall assembly process compared to manufacturing a single complex piece.
Solution Approach 2:
The separate side sections and center section design provides flexibility in manufacturing and installation. The modular approach allows standardization of production processes while accommodating various deck configurations, making the system more versatile and easier to manufacture compared to custom-bent single-piece glass solutions.

AI summary
A windshield assembly includes a windshield with a starboard side section, a port side section, and a center section between the starboard side section and the port side section. Transition areas of the windshield between the starboard side section and the center section and between the port side section and the center section, respectively, each include a transition radius. A bottom trim member is securable to a deck or frame with a profile including a starboard corner radius and a port corner radius. The bottom trim member supports the windshield and includes a pair of transition members disposed at the transition areas of the windshield. The transition members are configured to adapt the transition areas of the windshield to the deck profile.
