Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical transceiver concepts for mobile communications devices require complex and interference-prone electrical constructions to maintain high data transmission rates, especially in applications where line-of-sight links are challenging due to user mobility and shadowing, and they often necessitate extensive wiring and multiple optoelectronic components.
Innovation Solution
A light guide arrangement with a central optoelectronic interface component and a light guide body that uses multiple optical coupling members with lens elements and deflection elements to enable multidirectional optical data transmission, allowing for a simpler, interference-proof design with reduced component complexity and wiring by focusing light into a single point for reception or transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multidirectional transceiver units are used to maintain line-of-sight link, then reliability of optical data transmission is improved, but device complexity increases
Solution Approach 1:
Multiple optical coupling members (first, second, and third optical coupling members with different optical axes) are merged into a single light guide arrangement, allowing multidirectional transmission capability to be achieved through one integrated component rather than separate transceiver units
Solution Approach 2:
The light guide arrangement is designed to perform multiple functions: it can transmit and receive optical signals in multiple directions simultaneously, serving both as transmitter and receiver across different spatial orientations, eliminating the need for separate dedicated transceiver units for each direction
2Productivity
If multiple optoelectronic components are used to ensure high data transmission rate, then productivity is improved, but device complexity increases
Solution Approach 1:
Multiple optical coupling members are combined within a single light guide body, reducing the number of discrete components that would otherwise be required to achieve the same multidirectional high-speed data transmission capability
3Reliability
If extensive wiring is used to connect multiple components, then reliability of data transmission is improved, but ease of manufacture decreases
Solution Approach 1:
Multiple optical coupling members are integrated into a single light guide arrangement, eliminating the need for extensive wiring connections between separate components and simplifying the manufacturing process while maintaining signal transmission reliability
