Solution Overview
Problem
Motor vehicle assistance systems, such as cameras, face challenges with thermal management due to increasing computing demands and solar radiation, leading to heat buildup and potential damage, which necessitates high production costs or partial system shutdowns.
Innovation Solution
A camera assistance system with a shell-shaped cap and two cooling bodies with comb-shaped fins, where the camera housing is thermally connected to a lightweight aluminum cooling body and the cap has a high thermal absorption coefficient, enhancing heat dissipation through enlarged surface area and convection, without the need for fans or additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the camera is located in an interior area of the motor vehicle and covered by a cap, then visual appearance is improved, but heat dissipation becomes difficult leading to thermal overload
Solution Approach 1:
The cap is segmented into multiple portions with cooling channels integrated therein, allowing heat to be dissipated through the cap structure itself while maintaining the aesthetic covering function. This segmentation enables simultaneous achievement of visual appearance and thermal management.
Solution Approach 2:
Cooling air is introduced as an intermediary medium between the camera housing and the external environment. The cooling channels within the cap facilitate the flow of this intermediary cooling air to absorb and remove heat from the camera components, resolving the thermal overload issue while the cap maintains its visual covering function.
2Productivity
If computing capacity is increased to meet processing demands, then image processing capability is improved, but thermal loss increases leading to heat buildup
Solution Approach 1:
The cooling channels in the cap convert the harmful thermal loss from high-performance computing into a manageable thermal flow path. The channels guide the hot air generated by high-capacity processors through designated paths to external openings, transforming the waste heat into a controlled thermal management system that enables sustained high-performance operation.
3Reliability
If the camera housing is sealed to protect components, then reliability is improved, but heat discharge becomes impossible
Solution Approach 1:
The cooling channels are nested within the cap structure itself, creating a hierarchical arrangement where the sealed camera housing is protected while the outer cap contains integrated cooling pathways. This nested design allows the internal components to remain sealed and protected while the external cap structure facilitates heat discharge through its embedded channels.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system efficiently manages heat dissipation, maintaining reliable operation at high temperatures while reducing production costs and eliminating the need for fans, thus ensuring safe and cost-effective operation in various environmental conditions.
Implementation Method 1
The camera housing comprises a first cooling body with first cooling fins... The first cooling body is advantageously produced from a thermally conductive material, in particular a metal or a thermally conductive plastic
Implementation Method 2
a gap is formed in particular between the camera and the cap, which is filled with surrounding air... the cap has a high thermal absorption coefficient, enhancing heat dissipation through enlarged surface area and convection
Implementation Method 3
Due to the cooling fins, the surface of the first cooling body is enlarged, so that a thermal exchange and thus a thermal discharge from the camera acting as a heat source is improved
