Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle roof systems face challenges in maintaining environment sensors within a suitable temperature range due to unintentional absorption of cooling capacity by the support structure, affecting their operation.
Innovation Solution
A vehicle roof design with thermal decoupling members between the sensor mount and support structure, allowing controlled temperature management of environment sensors without dissipating energy into the support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the environment sensors are directly attached to the support structure, then the mounting is simple and stable, but the cooling capacity introduced for temperature control unintentionally affects the support structure
Solution Approach 1:
A thermal decoupling member is introduced as an intermediary element between the support structure and the mount for environment sensors. This decoupling member has thermally insulating properties that prevent heat transfer between the sensors and the support structure, allowing independent temperature control of the sensors without affecting the support.
Solution Approach 2:
The mounting system is segmented into distinct thermal zones by introducing the thermal decoupling member. This segmentation separates the thermal management of the environment sensors from the support structure, enabling independent temperature control and preventing unwanted heat transfer between the two components.
2Temperature
If thermal decoupling members are introduced between the support and mount, then temperature control of sensors is improved, but the device complexity increases
Solution Approach 1:
The thermal decoupling member serves as a simple intermediary element that provides thermal isolation without adding significant structural complexity. It can be implemented as a straightforward insulating component or layer between the support and mount, maintaining design simplicity while achieving effective thermal management.

Function Achieved in This Case
Ensures effective temperature regulation of environment sensors, preventing heat transfer to the support and enabling efficient operation of sensors for autonomous driving systems.
Implementation Method 1
Thermal decoupling members are disposed between the support and the mount in order to be able to cool and/or heat the environment sensors in a defined manner without part of the energy expended for this purpose dissipating into the support
