Solution Overview
Problem
Current laminated vehicle glazing with AMOLED screens face challenges in integrating a flexible and efficient electrical connection system that enhances mechanical strength and reduces visible components, while maintaining transparency and aesthetic appeal.
Innovation Solution
A laminated vehicle glazing design featuring a flexible AMOLED screen integrated within the lamination insert, with a flexible electrical connection element that extends beyond the edge of the second glazing, and an interface box connected via a wired system for power and data transmission, utilizing a non-zero thickness lamination insert to conceal connectors and enhance mechanical strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a flexible AMOLED screen is integrated within the lamination insert, then the mechanical strength and aesthetic appearance are improved, but the complexity of electrical connection increases
Solution Approach 1:
The patent employs a flexible printed circuit board (FPCB) as the electrical connection element, which can bend and conform to the curved surface of the lamination insert. This flexible connection element integrates seamlessly within the lamination structure, providing both mechanical strength and electrical connectivity without compromising the aesthetic appearance or increasing complexity significantly.
Solution Approach 2:
The electrical connection element is nested within the lamination insert, with the FPCB concealed between the inner and outer glazings. This nesting approach hides the electrical components within the existing structural layer, maintaining a clean external appearance while providing robust electrical connections to the AMOLED screen.
2Ease of operation
If the electrical connection element extends beyond the edge of the second glazing, then the ease of connection is improved, but the aesthetic appearance deteriorates due to visible components
Solution Approach 1:
The connection terminal is extracted and positioned at the periphery of the lamination insert, separate from the main display area. This allows the connection element to extend beyond the glazing edge for ease of connection while the main body remains concealed within the lamination, minimizing aesthetic impact.
Solution Approach 2:
The lamination insert provides different functions at different locations: the central area conceals the AMOLED screen and main connection elements for aesthetic purposes, while the peripheral area allows the connection terminal to extend outward for ease of connection. This local differentiation resolves the contradiction between aesthetics and ease of operation.
3Shape
If a non-zero thickness lamination insert is used to conceal connectors, then the aesthetic appearance is improved, but the volume of the glazing increases
Solution Approach 1:
The patent uses a thin-film FPCB as the electrical connection element, which requires minimal thickness to accommodate. This allows the lamination insert to maintain a non-zero thickness for aesthetic purposes while keeping the overall volume increase to a minimum, as the flexible circuit board can be made extremely thin.
Solution Approach 2:
The patent optimizes the thickness parameters of the lamination insert and FPCB to achieve the desired balance. By carefully selecting the thickness of each layer, the design maintains sufficient thickness to conceal connectors aesthetically while minimizing the total volume addition to the glazing structure.
