Solution Overview
Problem
Existing technologies lack a robust and effective solution for monitoring physical parameters of felt and its environment in industrial applications, where high temperatures and physical conditions pose challenges for traditional electronic components and sensor placement.
Innovation Solution
A felt and environment monitoring system comprising independent measuring units with sensors for temperature, humidity, pH, pressure, or air flow, a central acquisition unit with a microcontroller and communication transceivers, and a polymeric encapsulation material layer for thermal protection, along with inertial sensors for energy conservation and a network architecture for data collection and validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electronic components and sensors are placed directly in the felt monitoring system, then measurement capability is provided, but the components fail under high temperatures and extreme physical conditions
Solution Approach 1:
The system divides the monitoring function into separate modular units (independent measuring units) that can be individually protected and replaced. Each unit contains specific sensors for temperature, humidity, pH, pressure, or air flow, allowing targeted protection strategies for each measurement function rather than protecting a single integrated system.
Solution Approach 2:
The patent introduces a polymeric encapsulation material as an intermediary between the electronic components/sensors and the extreme environment. This encapsulation layer acts as a protective barrier that isolates the sensitive electronic components from direct exposure to high temperatures and harsh physical conditions while still allowing the sensors to detect environmental parameters.
2Object-affected harmful factors
If polymeric encapsulation material with low thermal conductivity is used to protect sensors, then thermal protection is improved, but heat transfer necessary for temperature sensing is reduced
Solution Approach 1:
The encapsulation material provides different levels of thermal protection locally - the polymeric material protects components from extreme external temperatures while the temperature sensor itself remains in direct contact with the felt or environment being monitored. This creates a gradient where different parts of the system experience different thermal conditions appropriate to their function.
Solution Approach 2:
The patent uses a thin polymeric encapsulation layer that provides thermal protection while maintaining thermal responsiveness. The thin film structure allows heat to conduct through to the temperature sensor quickly enough for accurate measurement, while still providing sufficient protection against extreme external temperatures. The flexibility of the thin film also allows it to conform to the sensor geometry.
3Reliability
If multiple independent measuring units are distributed on the felt, then monitoring coverage is improved, but system complexity and installation difficulty increase
Solution Approach 1:
Each independent measuring unit is designed as a universal module capable of measuring multiple parameters (temperature, humidity, pH, pressure, air flow) using the same basic architecture. This multi-functionality reduces overall system complexity because the same unit design can be deployed throughout the felt, and the central acquisition unit handles all data processing uniformly regardless of which specific parameters are being measured at each location.
