Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple optical components are arranged within the optoelectronic module, then the functionality of the module is enhanced, but the relative positioning of these components and optical fibers complicates the assembly process

Engineering Contradiction:
ImprovefunctionalityVSAvoidassembly process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The positioning member includes a base portion and multiple vertical portions with receptacles arranged in a nested configuration. Optical components are received within receptacles that are positioned at different heights on the vertical portions, creating a compact nested arrangement that simplifies assembly while maintaining multiple functional components within the module.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Volume of moving object

If components are positioned closer together to reduce module size, then the compactness is improved, but heat generated during operation adversely affects the functionality of certain components

Engineering Contradiction:
Improvemodule sizeVSAvoidoperating temperature
Core Design Contradiction:
Volume of moving objectVSTemperature

Solution Approach 1:

The positioning member is configured with receptacles at different vertical positions and orientations, allowing components with different thermal characteristics to be positioned in optimal locations. Heat-generating components can be placed in receptacles that facilitate heat dissipation, while temperature-sensitive components are positioned in cooler areas, thereby managing thermal conditions within the compact module structure.

Inventive Principle:
Principle #3Local quality

3Reliability

If components are arranged to optimize heat dissipation, then the reliability is improved, but the assembly process becomes more complex

Engineering Contradiction:
Improvemodule reliabilityVSAvoidcomponent arrangement
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The positioning member serves multiple functions simultaneously: it provides mechanical support for optical components, establishes precise positioning and alignment, and facilitates heat dissipation through its vertical portion structure that enables optimal orientation of components relative to heat sinks or cooling surfaces. This multi-functionality reduces the need for separate components, thereby simplifying the overall assembly process while maintaining reliable heat management.

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

AI summary

An optoelectronic module includes a housing and a printed circuit board (“PCB”) positioned within the housing. A positioning member is coupled to the PCB and includes one or more receptacles each configured to receive and secure positioning of an optical component relative to the PCB. The positioning member may include a plurality of receptacles positioned relative to one another in an arrangement defining a vertical array of receptacles, a lateral array of receptacles, or both. In one form, an optical component, when positioned in a receptacle of the positioning member, is spaced from the PCB. The positioning member may be formed of a thermally insulative or thermally conductive material, and a number of optical fibers may be routed between the positioning member and the housing.
