Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spatial optical communication systems face challenges in achieving a 360-degree communication angle due to physical blockages and limited directional coverage, as they rely on specific alignment of transmission/reception elements which can result in incomplete signal reception.
Innovation Solution
A reception device comprising a ball lens, a light receiver with integration light receiving elements, and a support column that allows the light receiver to be moved around the ball lens, enabling a 360-degree orientation and adjustment based on signal intensity, ensuring optimal signal reception and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single transmission/reception element is used for spatial optical communication, then the device complexity is reduced, but the communication angle is limited and cannot achieve 360 degrees
Solution Approach 1:
The single transmission/reception element is segmented into multiple transmission/reception elements arranged in different directions. Each element can independently receive signal light from different incident directions, enabling the system to achieve 360-degree communication coverage while maintaining relatively simple device structure.
Solution Approach 2:
Each transmission/reception element is designed with multi-functionality to handle signal light from various incident directions. The elements are positioned and oriented to collectively cover all directional angles, allowing the system to universally communicate from any direction without requiring complex directional adjustment mechanisms.
2Adaptability or versatility
If multiple transmission/reception elements are arranged to achieve 360-degree coverage, then the communication angle is improved, but the device complexity increases
Solution Approach 1:
Multiple transmission/reception elements are merged into a unified structure where they share common support and control mechanisms. The elements are integrated in a compact arrangement around the communication axis, reducing overall device complexity while maintaining 360-degree communication capability.
Solution Approach 2:
The transmission/reception elements are arranged in a three-dimensional configuration around the communication axis rather than in a simple linear or planar array. This spatial distribution in multiple dimensions allows comprehensive angular coverage with fewer elements, reducing device complexity.
3Device complexity
If the light receiver is fixed in position, then the device complexity is reduced, but the signal reception efficiency is insufficient when signal light intensity varies from different directions
Solution Approach 1:
The light receiver is designed with dynamic positioning capability, allowing it to move to different positions around the ball lens based on the incident direction of signal light. This dynamic adjustment enables the receiver to maintain optimal alignment with the ball lens regardless of signal direction, improving reception efficiency without requiring complex fixed-position arrays.
Solution Approach 2:
The system incorporates feedback mechanisms that detect the intensity and direction of incoming signal light, then automatically adjust the position of the light receiver accordingly. This feedback-controlled positioning ensures optimal signal reception while keeping the device structure relatively simple.
