Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle windows lack the capability to function as acoustical transducers for sound reproduction, and existing laminated glass structures do not effectively integrate excitable glass panes to generate sound while maintaining structural integrity and safety.
Innovation Solution
A composite glass panel comprising a primary glass pane, a secondary glass pane, and at least one excitable glass pane, separated by an isolative material section, with an exciter mounted to generate sound, and a structural adhesive layer for bonding, forming a laminated structure that can be used as a speaker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laminated glass structure is used to provide acoustical insulation and UV protection, then the glass panel achieves better protective functionality, but the structure becomes more complex and difficult to integrate with acoustical transducer elements
Solution Approach 1:
The patent combines multiple functions into a single laminated glass assembly: the primary and secondary glass panes provide structural integrity and protection, while the integrated excitable glass pane serves as both a structural element and an acoustical transducer. The isolative material section is embedded within the lamination structure itself, merging acoustic isolation with the protective glass layers rather than adding separate components.
Solution Approach 2:
The glass panes perform multiple functions simultaneously: they provide mechanical strength and safety (controlled fracture), acoustical insulation, UV protection, and sound reproduction capability. The excitable glass pane specifically serves dual purposes as both a structural component of the laminated assembly and an active acoustical transducer element.
2Adaptability or versatility
If excitable glass panes are integrated into the laminated structure for sound reproduction, then the window gains acoustical transducer functionality, but the structural integrity and safety of the glass panel may be compromised
Solution Approach 1:
The excitable glass pane is merged into the laminated glass structure as an integral layer rather than an add-on component. It is bonded to the primary glass pane via adhesive layers and positioned within the lamination assembly, allowing it to contribute to both structural integrity and acoustical functionality simultaneously.
Solution Approach 2:
Adhesive layers serve as intermediary bonding agents between the excitable glass pane and the primary glass pane, ensuring strong structural attachment while allowing the excitable pane to maintain its piezoelectric properties for sound reproduction. The isolative material section also acts as an intermediary to acoustically isolate specific regions.
3Reliability
If multiple glass panes and isolative material sections are arranged in a laminated structure, then the panel achieves better acoustical insulation and controlled fracture, but the manufacturing process becomes more complex
Solution Approach 1:
The laminated glass panel is segmented into distinct functional layers: primary glass pane for structural support, excitable glass pane for acoustical transduction, secondary glass pane for additional protection, and isolative material sections for acoustic isolation. This segmentation allows each layer to be optimized for its specific function while being manufactured as an integrated assembly.
Solution Approach 2:
The patent employs composite material construction by combining different types of glass panes with isolative materials and adhesive layers into a single laminated structure. This composite approach enables simultaneous achievement of acoustical insulation, UV protection, controlled fracture characteristics, and acoustical transducer functionality through material selection and layering rather than complex mechanical assembly.

AI summary
An acoustical transducer composite glass panel includes a primary glass pane, a secondary glass pane, and at least one excitable glass pane configured to acoustically respond to an excitation stimulus. The composite glass panel also includes an isolative material section configured to separate a corresponding excitable glass pane from the secondary glass pane. The secondary glass pane is arranged along the primary glass panel and equidistant therefrom. Each excitable glass pane is arranged along the primary glass panel and equidistant therefrom and adjacent to the secondary glass pane, and a first portion of each excitable glass pane is spaced apart from the primary glass pane. Additionally, the isolative material section is arranged along the primary glass panel and equidistant therefrom, between an edge of the secondary glass pane and an edge of a second portion of the corresponding excitable glass pane.
