Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing black-print display systems in motor vehicles are prone to overheating, which can impair their performance and reduce their service life.
Innovation Solution
A cooling system is integrated into the vehicle's instrument panel to provide airflow for heat dissipation and cooling, utilizing a control unit to monitor and adjust airflow direction based on the display system's operating state, with optional integration of a sensor unit to detect temperature and initiate targeted cooling processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a black-print display system is used in the instrument panel, then information can be displayed to the driver and passenger through reflection, but the display system is prone to overheating which impairs performance and reduces service life
Solution Approach 1:
The instrument panel is divided into functional zones with separate cooling channels for the display system and climate control zones. This segmentation allows independent temperature management, directing cooled air specifically to the display system without being affected by overall cabin temperature or other panel components.
Solution Approach 2:
A cooling channel acts as an intermediary between the climate control system and the display system. This intermediate structure transports cooled air from the climate control unit to the display system, enabling indirect cooling without direct thermal contact between the display and the panel's other components.
2Temperature
If a cooling system is integrated into the instrument panel, then the display system can be cooled effectively, but the device complexity increases
Solution Approach 1:
The cooling system for the display system is merged with the existing climate control system of the vehicle. The cooling channel is integrated into the instrument panel structure, sharing space and components with the climate control system, thereby reducing overall complexity compared to implementing a separate dedicated cooling system.
Solution Approach 2:
The cooling channel serves multiple functions: it cools the display system, and can potentially serve other heat-generating components in the instrument panel. This multi-functionality reduces the need for separate cooling systems for different components, simplifying the overall device structure.
3Temperature
If manual cooling intervention is required, then cooling can be provided, but loss of time occurs and automated operation is reduced
Solution Approach 1:
A sensor unit detects the temperature or operating state of the display system and provides feedback to the control unit. Based on this feedback, the control unit automatically activates or adjusts the cooling channel, eliminating the need for manual intervention and reducing response time.
Solution Approach 2:
The cooling system is designed to activate automatically based on the display system's operating state without requiring user input. The system monitors itself and initiates cooling when needed, making the cooling process self-service and reducing time loss associated with manual activation.
