Optical Module Window Fusion for Wider Light Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited transmission area of windows for optical modules in electronic devices restricts design freedom and can visually expose internal elements, especially when the attachment area is decorative.
Innovation Solution
The window is fused to the housing or window frame using laser fusion, reducing the attachment area to 0.5 mm or less while maintaining or enhancing bonding strength, allowing for improved design freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the attachment area of the window is increased to ensure bonding strength, then the bonding reliability is improved, but the light transmission area is reduced and design freedom is limited
Solution Approach 1:
The patent changes the bonding method from mechanical attachment to laser fusion, fundamentally altering the bonding parameters. This enables achieving high bonding reliability with minimal attachment area (0.5 mm or less), thereby maximizing light transmission area while maintaining structural integrity
Solution Approach 2:
The patent replaces mechanical bonding systems (adhesives, mechanical fasteners) with laser fusion technology. This substitution eliminates the need for large attachment areas required by mechanical methods, as laser fusion achieves strong bonding through localized melting and fusion at the interface, significantly reducing the attachment area while improving bonding reliability
2Shape
If the attachment area is made decorative to enhance外观设计, then aesthetic appearance is improved, but internal elements may be visually exposed and design freedom is restricted
Solution Approach 1:
By changing the bonding method to laser fusion, the attachment area is reduced to 0.5 mm or less, which is too small to be visually significant. This allows the window edge to appear clean and seamless, providing design freedom for various aesthetic configurations without being constrained by visible attachment areas
Solution Approach 2:
The patent extracts the attachment function from the visible window area and concentrates it into a minimal interface region through laser fusion. This separation allows the main window surface to be fully dedicated to aesthetic and optical functions, while the bonding function is fulfilled in an invisible, minimal zone
3Use of energy by moving object
If the attachment area is reduced to maximize light transmission, then light transmission efficiency is improved, but bonding strength may be compromised
Solution Approach 1:
The patent replaces mechanical bonding with laser fusion, which creates molecular-level bonding through melting and fusion. This enables achieving exceptional bonding strength in a minimal area (0.5 mm or less), thereby maximizing light transmission efficiency without compromising structural integrity
Solution Approach 2:
The patent fundamentally changes the bonding mechanism from surface-level mechanical attachment to deep material fusion. This parameter change enables concentrating bonding strength into a minimal attachment area, allowing the majority of the window area to be dedicated to light transmission while maintaining adequate bonding strength
