Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multilayer composite articles with integrated sensors face challenges in transmitting measurement data externally without compromising the article's integrity, and existing wireless data transmission methods like RFID are prone to unauthorized access and signal confusion in complex systems.
Innovation Solution
Integrate a sensor device with a transmitter that converts electrical measurement data into optical signals using a light source, allowing secure and non-invasive data transmission through a multilayer composite article by emitting light emissions that can be detected externally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a direct wire connection is used to transmit measurement data from the sensor device, then data transmission is reliable, but the integrity of the multilayer composite article is compromised due to reduced thickness and strength at conductor exit points
Solution Approach 1:
The patent replaces the electrical/wire-based data transmission system with an optical transmission system. A light source (LED or laser diode) converts electrical measurement data into optical signals that can pass through the multilayer composite article without physical conductors, thereby maintaining structural integrity while enabling reliable data transmission.
Solution Approach 2:
The patent introduces an optical intermediary (light signals) as a mediator between the embedded sensor device and external evaluation units. This intermediary enables data transmission without requiring direct physical connections through the article layers, thus preserving structural strength.
2Strength
If wireless RFID data transmission is used, then the article integrity is maintained, but the data can be easily accessed by unauthorized persons and signal assignment becomes difficult in complex systems
Solution Approach 1:
The patent replaces wireless RFID electromagnetic transmission with optical signal transmission. Optical signals have directional propagation characteristics and can be confined to specific paths, making unauthorized interception significantly more difficult compared to omnidirectional RFID signals.
Solution Approach 2:
The patent implements localized optical signal transmission through specific exit points on the article surface. The optical signals are transmitted through designated transparent or translucent regions, creating localized transmission zones that are easier to control and secure compared to widespread RFID signal coverage.
3Adaptability or versatility
If multiple sensor devices are integrated into a multilayer composite article, then comprehensive monitoring is achieved, but the complexity of assigning and managing multiple transmission signals increases significantly
Solution Approach 1:
The patent divides the optical transmission system into segmented, dedicated channels. Each sensor device has its own specific exit point and transmission path on the article surface, allowing individual signal routing and evaluation. This segmentation simplifies signal assignment and management compared to managing multiple overlapping wireless RFID signals.
