Vehicle Streaming Box Thermal Control for Heat and Moisture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing streaming boxes developed for home entertainment are not suitable for use in vehicles due to temperature and moisture fluctuations, and are often incompatible with the 12V on-board electrical system.
Innovation Solution
A heat management method that involves using sensors to determine the heat discharge or supply requirements of a streaming box in a vehicle, and automatically actuating the vehicle's air pump and heating/air-conditioning system to maintain suitable thermal conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If streaming boxes designed for home entertainment are used in vehicles, then multimedia capabilities are improved, but reliability deteriorates due to temperature and moisture fluctuations
Solution Approach 1:
The patent introduces a housing (1) with a specific geometric design that acts as an intermediary between the streaming box and the vehicle environment. This housing includes heat discharge paths and ventilation slots that mediate the thermal interaction, allowing the streaming box to operate in vehicle conditions without direct exposure to extreme temperature and moisture fluctuations.
Solution Approach 2:
The patent changes the thermal parameters of the environment surrounding the streaming box by providing active cooling through ventilation slots and heat discharge paths. The system modifies local temperature and airflow parameters to create a suitable operating environment for the streaming box within the vehicle.
2Ease of operation
If streaming boxes with internal power supply units are used, then ease of operation is improved, but adaptability deteriorates due to incompatibility with 12V on-board electrical system
Solution Approach 1:
The patent extracts the power supply function from the streaming box by providing a separate power supply unit (6) integrated into the vehicle's electrical system. This separation allows the streaming box to be connected via simple data/Power over Ethernet cables while the power conversion from 12V to 5V is handled by the dedicated power supply unit in the vehicle.
3Ease of manufacture
If streaming boxes are installed in disadvantageous locations within the vehicle, then ease of installation is improved, but heat discharge capability deteriorates
Solution Approach 1:
The patent addresses heat discharge by introducing vertical and lateral airflow dimensions through the housing design. The ventilation slots and heat discharge paths create three-dimensional airflow patterns that efficiently remove heat from the streaming box regardless of its horizontal installation location within the vehicle.
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
Enables the operation of streaming boxes in vehicles by maintaining suitable temperature and moisture levels, ensuring continued operation even in adverse conditions and without the need for user intervention.
Implementation Method 1
an air pump and/or a heating/air-conditioning device of the vehicle can then be automatically actuated in order to supply heat to or draw heat from the streaming box
Implementation Method 2
The temperature of the streaming box or a housing of the vehicle surrounding the streaming box can be directly determined by a temperature sensor signal
