Solution Overview

Problem

Conventional optical modules face challenges in optical power management, space management, thermal management, insertion loss, and manufacturing yield, and the assembly process is time-consuming and prone to damage optical fibers during automatic assembly due to compression, tangling, and self-twisting.

Innovation Solution

An optical transmission assembly that includes a holder with predetermined positions for optical receptacles, allowing for quick assembly and preventing fiber damage by coupling optical receptacles to the holder before assembly with an adapter, facilitating both manual and automatic assembly processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If optical receptacles are assembled directly to the adapter without a holder, then the assembly process is simpler, but the optical fibers are prone to damage from compression, tangling, and self-twisting during automatic assembly

Engineering Contradiction:

Improveassembly process simplicityVSAvoidoptical fiber integrity

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The holder provides predetermined positions for optical receptacles before assembly with the adapter, allowing optical receptacles to be coupled to the holder in advance. This preliminary positioning prevents fiber damage during subsequent assembly operations while maintaining assembly efficiency through standardized mounting locations.

Inventive Principle:

Principle #10Preliminary action

2Device complexity

If optical receptacles are positioned without predetermined locations, then the device structure is simpler, but the assembly time increases and positioning accuracy decreases

Engineering Contradiction:

Improvestructural complexityVSAvoidassembly time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The holder is designed with predetermined positions for optical receptacles, establishing standardized mounting locations before the assembly process begins. This preliminary structural preparation enables rapid and accurate positioning during assembly, reducing assembly time while maintaining reasonable structural complexity.

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If multiple optical receptacles are assembled without a holder structure, then the device is easier to manufacture, but the positioning precision and assembly quality decrease

Engineering Contradiction:

Improvemanufacturing easeVSAvoidoptical receptacle positioning precision

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The holder incorporates predetermined positions and mounting structures for optical receptacles before the assembly process. This preliminary preparation ensures consistent and precise positioning of multiple optical receptacles during assembly, improving manufacturing precision while maintaining ease of manufacture through standardized mounting procedures.

Inventive Principle:

Principle #10Preliminary action
