Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heating devices for camera modules are inefficient in rapidly preventing frost or condensation on lenses, especially in extreme temperatures, and may pose a fire risk due to prolonged heating times or high heat generation.
Innovation Solution
A hyper heat accelerator, comprising spherical dots of materials like SnF2, SnF4, or tin nickel fluoride arranged in a lattice form on a metal oxide layer with a conductive adhesive, is used to create a heating device that accelerates temperature elevation and extends the heat range, allowing for rapid and safe removal of moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a hot wire is used to prevent frost or condensation on the lens, then the lens temperature can be elevated, but it takes a long period of time to reach the desired temperature level
Solution Approach 1:
The patent introduces hyper heat accelerator dots (metal fluoride nanoparticles) on the heating element surface to change the thermal parameters of the system. These nanoparticles accelerate heat transfer from the hot wire to the lens, enabling the lens to reach desired temperature levels faster than conventional hot wire heating alone.
Solution Approach 2:
The heating device uses a composite structure combining the hot wire (heating element) with hyper heat accelerator dots (metal fluoride nanoparticles such as SnF2, SnF4, or their alloys). This composite material system enhances heat transfer efficiency, resolving the contradiction between achieving sufficient temperature elevation and reducing heating time.
2Temperature
If the external temperature is extremely low, then the lens requires higher temperature elevation to prevent frost, but it takes even longer time to achieve the desired temperature
Solution Approach 1:
The hyper heat accelerator dots modify the thermal transfer parameters between the hot wire and lens, enabling faster temperature elevation even when the external temperature is extremely low. The nanoparticles facilitate rapid heat transfer, compensating for the larger temperature differential required in cold environments.
3Reliability
If heat is generated from the hot wire when external temperature is high, then the lens can be protected from condensation, but there is a risk of fire of the camera module
Solution Approach 1:
The hyper heat accelerator dots are applied locally on the heating element surface in contact with or near the lens. This localized application concentrates the heat acceleration effect where it is most needed (at the lens interface), allowing the system to achieve effective condensation protection with reduced overall heat generation, thereby lowering fire risk.
Solution Approach 2:
The metal fluoride nanoparticles act as an intermediary between the hot wire and the lens, facilitating more efficient heat transfer. This intermediary enables the system to achieve the required lens temperature with lower hot wire power output, reducing the fire hazard while maintaining condensation protection effectiveness.
4Productivity
If conventional heating methods are used, then the structure is simple, but the heating efficiency is low and cannot rapidly remove dampness or frost
Solution Approach 1:
The introduction of hyper heat accelerator dots changes the thermal parameters of the heating system, transforming it from a low-efficiency conventional heater to a high-efficiency rapid heating device. The nanoparticles enable fast heat transfer, achieving rapid removal of dampness or frost.
Solution Approach 2:
The heating device employs a composite material system combining conventional hot wire with metal fluoride nanoparticle coatings. This composite structure maintains the simplicity of the basic heating element while dramatically improving heating efficiency through the added functional layer of hyper heat accelerator dots.
