Vehicle Glass Module With Visible Adhesive Check for Sensor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The attachment of information acquisition devices in vehicles is often secured with double-sided adhesive tape and adhesive, but the adhesive is hidden by a mask layer, making it difficult to confirm if the adhesive is properly applied, leading to potential detachment risks.
Innovation Solution
A glass plate module with laminated glass and a mask layer, featuring adhesive confirmation portions that allow visibility of the adhesive from the vehicle interior, ensuring proper adhesion through first and second adhesion means, including double-sided adhesive tape and preliminary fixing before curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate production and assembly steps are used for glass plates with functional layers, then manufacturing flexibility is maintained, but production time and costs increase
Solution Approach 1:
The patent combines multiple functional layers (conductive layer, transparent resin layer, ITO layer) and the glass plate into a single integrated structure that can be produced in one continuous process. The functional layers are formed directly on the glass plate substrate during the same production run, eliminating separate assembly steps and reducing overall production time while maintaining manufacturing flexibility.
2Device complexity
If functional layers are integrated into the glass plate structure, then module assembly is simplified, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the production process into distinct zones within the same production line: a first production line forms the conductive layer and transparent resin layer, while a second production line forms the ITO layer. This segmentation allows each layer to be manufactured with optimized precision controls specific to its requirements, while the overall module structure remains integrated and simplified.
3Manufacturing precision
If multiple production lines are used for different functional layers, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent designs the production system so that multiple production lines perform overlapping functions. Both the first and second production lines can form various types of functional layers (conductive layers, transparent resin layers, ITO layers) on different glass plates. This multi-functionality allows precise control of each layer while maintaining a unified production system architecture, reducing overall device complexity.

AI summary
The present invention provides a glass plate module to be attached to a vehicle. The glass plate module includes laminated glass in which an outer glass plate, an interlayer, and an inner glass plate are layered in this order; a mask layer that is provided on the laminated glass and blocks a field of vision from outside; and an attachment member that is attached to a portion corresponding to the mask layer on the inner glass plate with at least a first adhesion means and a second adhesion means and configured to support an information acquisition device for acquiring information from outside of a vehicle. The first adhesion means includes adhesive at at least one location. The second adhesion means is configured such that the adhesive conducts preliminary fixing prior to curing. The attachment member includes a fixation portion that faces the mask layer and has a bonding surface provided with the adhesion means. The fixation portion includes at least one adhesive confirmation portion through which the adhesive applied to the bonding surface can be seen from the vehicle interior side.
