Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If optical fiber transmission is used with unidirectional feature, then signal transmission can be achieved, but spatial flexibility and signal distribution efficiency are limited

Engineering Contradiction:
Improvespatial flexibilityVSAvoidsignal distribution efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The optical signal is segmented into multiple directional paths using the light divergence structure, allowing a single optical source to serve multiple receivers simultaneously. This segmentation of the optical path resolves the contradiction by enabling one-to-many signal distribution while maintaining optical transmission efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The light divergence structure introduces angular dimensionality to the optical signal propagation, transforming unidirectional transmission into multi-directional transmission. By adding the angular dimension, the system achieves spatial flexibility without compromising signal distribution efficiency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If a single light source is used, then device complexity is reduced, but the ability to serve multiple receivers in different planes is limited

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The light divergence structure acts as an intermediary between the single light source and multiple optical receivers. This intermediary component enables the single source to effectively serve multiple receivers in different planes by diverging the optical signal in multiple directions, thus maintaining low device complexity while enhancing signal distribution capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The light divergence structure provides multi-functionality by enabling a single light source to simultaneously serve multiple receivers positioned in different planes and orientations. This universal approach allows one component to perform what would traditionally require multiple separate light sources.

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

If optical signal receivers are placed in various planes and depths, then signal receiving capability is improved, but device complexity increases

Engineering Contradiction:
Improvesignal receiving capabilityVSAvoidpackage structure complexity
Core Design Contradiction:

Solution Approach 1:

The light divergence structure merges the functions of multiple potential light sources into a single integrated component. This merging approach enables receivers in various planes and depths to be served by one unified structure, improving signal receiving capability while avoiding the complexity of multiple separate light sources and their associated mounting, alignment, and control systems.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A semiconductor photonic package includes a first photonic die and a second photonic die laterally disposed over a substrate, a light divergence structure disposed over the first photonic die and beside the second photonic die, and a light source disposed over the light divergence structure. The light source provides an optical signal vertically to the first photonic die, and the optical signal is reflected or refracted to be laterally directed to the second photonic die by the light divergence structure. The light divergence structure allows the optical signals to be directed to optical signal receivers in various locations and/or at various depths, and thus improves signal receiving in a multi-type semiconductor photonic package.
