Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Semiconductor devices in vehicle infotainment systems face performance and reliability issues due to sharp temperature fluctuations, potentially leading to abnormal operations and safety hazards.
Innovation Solution
A storage device with a controller and sensor that measures internal temperature and sends temperature information to a host, enabling thermal throttling operations to maintain the device within a stable reference temperature range, such as −40° C. to 85° C., by adjusting power consumption, command frequency, or cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If semiconductor devices operate in vehicle infotainment systems, then the device functionality and performance are improved, but temperature fluctuations cause reliability degradation and abnormal operations
Solution Approach 1:
The patent implements a temperature monitoring system where a sensor continuously measures the internal temperature of the storage device and feeds this information back to the controller. The controller then adjusts operating parameters based on the temperature feedback to maintain reliable operation within the reference temperature range of -40°C to 85°C.
Solution Approach 2:
The patent changes operational parameters (such as command frequency, power consumption levels, and processing speed) based on measured temperature conditions. When temperature exceeds the reference range, the system adjusts these parameters to reduce heat generation and maintain stable operation, thereby resolving the contradiction between functionality and temperature stability.
2Reliability
If thermal management operations are implemented to maintain temperature within reference range, then reliability is improved, but device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The patent integrates temperature monitoring and control functions into the existing storage device controller, allowing the controller to perform both data management operations and thermal management tasks. This multi-functionality approach reduces overall system complexity by eliminating the need for separate dedicated temperature control hardware while maintaining reliable operation within the reference temperature range.
