Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation devices in vehicles often malfunction or break due to extreme temperature fluctuations in the vehicle compartment, which can exceed the operating or storage limits of external devices connected to them, such as mobile phones or audio players.
Innovation Solution
A protection device with a connecting portion, power supply means, temperature detection means, and prohibition means that stops power supply to external devices when the temperature exceeds predetermined limits, and optionally includes a warning system to alert users of potential temperature risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the navigation device supplies power to external devices in the vehicle compartment, then the external devices can operate normally, but the external devices may malfunction or break when temperature exceeds operating limits
Solution Approach 1:
The temperature detection means continuously monitors the temperature in the vehicle compartment before it reaches harmful levels. When the temperature exceeds the predetermined operating limit, the prohibition means preemptively stops power supply to the external device, preventing malfunction or damage before it occurs. This preliminary protective action resolves the contradiction by maintaining reliability through preventive intervention.
Solution Approach 2:
The system establishes a feedback loop where temperature detection means continuously monitors environmental conditions, feeds this information to the temperature determination means, which compares it against predetermined limits, and triggers the prohibition means to stop power supply when limits are exceeded. This feedback mechanism dynamically adjusts power supply based on temperature conditions, resolving the contradiction between maintaining operation and preventing temperature-related damage.
2Reliability
If the navigation device continuously monitors temperature and stops power supply when limits are exceeded, then external devices are protected from temperature damage, but the device complexity increases
Solution Approach 1:
The protection device integrates multiple functions into a single system: the temperature detection means serves both as a monitoring device and a trigger for protection, the temperature determination means compares temperature against stored predetermined limits, and the prohibition means controls power supply. This multi-functional integration achieves external device protection while minimizing the increase in device complexity by consolidating components rather than adding separate systems.
Solution Approach 2:
The protection device is self-regulating through the integrated system where temperature detection automatically triggers determination and prohibition actions without requiring external intervention. The device monitors its own operational environment and autonomously adjusts power supply to protect external devices, reducing the need for additional control systems or manual oversight, thereby limiting complexity increase while achieving reliable protection.

AI summary
A protection device includes a connecting portion, power supply means, temperature detection means, temperature determination means, and prohibition means. The connecting portion is configured to be coupled with an external device for sending and receiving information with the external device. The power supply means supplies electric power to the external device through the connecting portion. The temperature detection means detects temperature in a vehicle compartment, and the temperature determination means determines whether the detected temperature is within a predetermined temperature limit. The prohibition means stops the power to the external device when the temperature determination means determines that the detected temperature is out of the predetermined temperature limit.
