Solution Overview
Problem
Conventional ultrasmall transceivers, such as the optical I/O core, occupy too much space for flexible PCB design in optical interconnection between ICs, hindering the increase in transceiver density for high-frequency signal transmission.
Innovation Solution
An optical device with an optical fiber, a base, an optical element, an electric element, and a rod-like reinforcing member with an integral structure, where the reinforcing member is fixed into holes in both the optical fiber and the base using an adhesive layer, allowing for a compact and high-strength transceiver design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ultrasmall transceivers (optical I/O core) are used, then optical interconnection between ICs is enabled, but the transceiver occupies too much space for flexible PCB design
Solution Approach 1:
The patent merges the optical fiber and base into a single integrated unit by forming a hole through both components and filling it with a reinforcing member. This integration eliminates the need for separate mounting structures, reducing the overall transceiver footprint while maintaining PCB design flexibility.
Solution Approach 2:
The reinforcing member is nested within the hole formed in the optical fiber and base, creating a compact hierarchical structure. The adhesive layer further nests within the gap between the reinforcing member and hole wall, maximizing space utilization and minimizing the transceiver's external dimensions.
2Quantity of substance
If the transceiver is downsized for increased density, then transceiver density increases, but mechanical strength may be compromised
Solution Approach 1:
The patent uses a composite structure combining the optical fiber, base, reinforcing member, and adhesive layer. Each material is selected for its specific properties: the optical fiber for optical transmission, the base for structural support, the reinforcing member for mechanical strength, and the adhesive for bonding. This composite approach achieves both downsizing and maintained strength.
Solution Approach 2:
The reinforcing member has a rod-like shape that provides structural integrity while fitting within the cylindrical hole. The curved/round geometry distributes stress more effectively than angular shapes, maintaining mechanical strength in the compactized transceiver structure.
3Area of stationary object
If the transceiver is downsized, then space is saved, but structural integrity and mechanical strength may be compromised
Solution Approach 1:
The hole is pre-formed in both the optical fiber and base before assembly, and the reinforcing member is prepared in advance. This preliminary preparation ensures that the structural reinforcement is integrated into the design from the outset, maintaining structural integrity while achieving the desired compact size.
Solution Approach 2:
The adhesive layer acts as an intermediary between the reinforcing member and the hole wall, ensuring strong bonding and structural integrity. This intermediate substance fills gaps and creates a unified structure, preventing separation and maintaining stability in the downsized transceiver.

AI summary
An optical element that is optically coupled to light inlet/outlet ends of an optical fiber is disposed on a base placed near the light inlet/outlet ends of the optical fiber. Moreover, a rod-like reinforcing member has an integral structure fixed into a first hole formed in the optical fiber and a second hole formed in the base 102.
