Solution Overview

Problem

High-speed fiber optic networks face challenges in reducing the size and production costs of hermetically sealed optoelectronic assemblies while maintaining performance, due to limited space and increased complexity with current ferrule assemblies and sealing structures, which also affect RF signal transmission and optical signal focus.

Innovation Solution

An optical component with a housing defining a cavity and a lens array on an optically transmissive portion, which simplifies production processes, reduces material costs, and decreases the size of hermetically sealed portions by integrating lenses and window seals, allowing for efficient optical signal transmission and focus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hermetically sealed ferrule assemblies are used to protect optoelectronic components, then reliability is improved, but device complexity and production cost increase

Engineering Contradiction:
Improvehermetic sealingVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the window seal and lens array into a single integrated component. The lens array is directly mounted on the window seal structure, eliminating the need for separate sealing and optical mounting operations. This merging reduces assembly complexity while maintaining hermetic sealing integrity and optical performance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The window seal structure serves multiple functions: it provides hermetic sealing, supports the lens array, and acts as part of the optical path. This multi-functionality reduces the number of separate components needed, simplifying the overall assembly while maintaining reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If traditional separate component assemblies are used, then ease of manufacture is maintained, but production cost and assembly time increase

Engineering Contradiction:
Improveproduction simplicityVSAvoidassembly efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

By integrating the lens array mounting directly onto the window seal, the patent reduces the number of discrete assembly steps. The lens array is positioned and secured in a single operation during window seal installation, rather than requiring separate mounting steps, thereby improving assembly efficiency without complicating manufacturing.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple discrete components are assembled, then adaptability is improved, but device complexity and space requirements increase

Engineering Contradiction:
Improvecomponent flexibilityVSAvoidassembly size
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The integration of lens array and window seal into a single compact structure reduces the overall volume required for these components. The combined structure eliminates gaps and interfaces between separate parts, achieving space efficiency while maintaining the functional adaptability of the optical system.

Inventive Principle:
Principle #5Merging (Combining)
