Vehicle Window Heating via Thermal Radiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image recording devices in vehicles face challenges in maintaining clear visibility through vehicle windows due to misting or icing, which existing solutions address inadequately by relying on thermal conduction from heating elements that can cause uneven heating and material stress.
Innovation Solution
A two-dimensionally arranged heating device, such as a heating foil, is integrated into a baffle plate that can be detachably connected to the carrier part, allowing for controlled thermal radiation to uniformly heat the vehicle window, minimizing scattered light and preventing misting or icing by varying radiant power per unit area and line length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heating elements are provided on the holding device to heat the vehicle window by thermal conduction, then the viewing area is protected from misting or icing, but uneven heating and material stress occur
Solution Approach 1:
The patent replaces thermal conduction heating (mechanical/physical contact heating) with thermal radiation heating (electromagnetic radiation heating). The heating device emits infrared radiation that directly heats the vehicle window without requiring thermal contact, thereby eliminating the material stress caused by uneven thermal conduction while maintaining effective protection against misting and icing.
Solution Approach 2:
The patent changes the heating mechanism from contact-based thermal conduction to radiation-based heating. The heating device is designed to emit thermal radiation in the direction of the vehicle window, fundamentally changing how heat is transferred and eliminating the uneven heating distribution that causes material stress.
2Temperature
If heating elements are provided on the holding device, then the vehicle window can be heated, but the heating is uneven and causes material stress
Solution Approach 1:
The patent substitutes thermal conduction with thermal radiation. The heating device emits infrared radiation that penetrates and distributes heat more uniformly across the vehicle window surface, eliminating the localized uneven heating that occurs with contact-based thermal conduction methods.
Solution Approach 2:
The patent introduces thermal radiation as an intermediary heating mechanism. Instead of direct thermal contact between the holding device and window, the heating device uses electromagnetic radiation as a mediator to transfer heat energy uniformly across the window surface, improving heating stability.
3Volume of moving object
If the holding device is positioned directly on the vehicle window, then space requirements are reduced, but cleaning access is limited
Solution Approach 1:
The patent divides the heating function from the structural holding function. The heating device is integrated into the holding device but positioned such that it can heat the window without blocking cleaning access. This segmentation allows the window to be cleaned from the outside while the heating element remains functional on the interior side.
Solution Approach 2:
The patent uses thermal radiation as an intermediary that can penetrate or act through the window structure. The heating device can be positioned on the interior side of the window and still effectively heat the entire window surface, including areas that need to be cleaned from the exterior, without blocking cleaning access.
