Solution Overview
Problem
Existing temperature determination methods in structures like vehicles and buildings are limited in their ability to accurately and efficiently measure temperature on both sides of a window, and often require separate sensors and systems for internal and external temperature monitoring.
Innovation Solution
A window-based temperature determination system that incorporates an optical grating, a light source, and a detector to measure temperature by analyzing the wavelengths of light after interaction with the grating, allowing for dual-sided temperature measurement and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate temperature sensors are used for internal and external temperature monitoring, then temperature measurement capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple temperature sensing functions into a single optical grating structure that can simultaneously measure temperatures on both sides of the window by analyzing wavelength shifts of light interacting with the grating
Solution Approach 2:
The optical grating serves multiple functions: it acts as a temperature sensor for both internal and external environments, maintains window transparency, and enables dual-sided temperature monitoring through a single integrated component
2Ease of operation
If temperature sensors are integrated into the window structure, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The optical grating is implemented as a thin-film structure that can be integrated into the window assembly, allowing temperature sensing functionality to be incorporated without significantly altering the window's structural properties or manufacturing processes
