Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dashcams with metal casings dissipate heat, causing discomfort when drivers adjust the camera angle with their hands due to high surface temperatures.
Innovation Solution
Incorporating thermal insulation components with lower thermal conductivity than the camera body on the side surfaces, ensuring the driver grips these components for rotation, which maintain lower temperatures and reduce discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the camera body is made of metal material for heat dissipation, then the heat dissipation performance is improved, but the surface temperature becomes high causing discomfort to the driver
Solution Approach 1:
The camera body is divided into two distinct parts: a metal camera body for heat dissipation and a separate thermal insulation component for user contact. This segmentation allows each part to fulfill its specific function without compromising the other - the metal body dissipates heat internally while the insulation component maintains a comfortable surface temperature for driver interaction.
Solution Approach 2:
The thermal insulation component acts as an intermediary between the hot metal camera body and the driver's hand. This intermediate layer blocks heat transfer to the user's skin while allowing the metal body to continue dissipating heat effectively, thus resolving the contradiction between heat dissipation performance and surface temperature comfort.
2Object-affected harmful factors
If thermal insulation components are added to the camera body, then the surface temperature comfort is improved, but the device complexity increases
Solution Approach 1:
The thermal insulation component is nested within or integrated with the camera body structure. The insulation component fits into the camera body housing, creating a compact integrated design where the insulation layer is contained within the overall device structure, minimizing additional complexity while maintaining thermal comfort.
Solution Approach 2:
The camera assembly combines two different materials - metal for the camera body and thermal insulation material for the outer component. This composite structure allows each material to perform its optimal function (metal for heat dissipation, insulation for thermal comfort) while being integrated into a single device unit, balancing performance improvement with manageable complexity.

AI summary
The vehicle camera includes a camera main body and two thermal insulation components. The camera main body has two side surfaces facing away from each other. The two thermal insulation components are respectively disposed on the side surfaces of the camera main body facing away from each other. Thermal conductivities of the two thermal insulation components are smaller than a thermal conductivity of the camera main body.
