Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems face challenges in ensuring that only high-quality battery modules are used, as lower-quality modules can cause problems and manufacturers want to prevent their security devices from being reused in different modules.
Innovation Solution
A monitoring device for battery modules that communicates via a first interface with a control device and via a second interface with either a security device or a temperature sensor, using the same connections for both operating modes, allowing for authentication of battery modules and monitoring of temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired security devices are used to communicate with battery modules, then reliability is improved, but device complexity increases due to necessary wiring
Solution Approach 1:
The second interface is designed to serve multiple functions: it communicates with security devices during authentication mode and communicates with temperature sensors during operation mode. This multi-functionality eliminates the need for separate dedicated wiring for security devices, reducing overall wiring complexity while maintaining reliable wired communication
Solution Approach 2:
The patent combines the communication functionality for security devices and temperature sensors into a single second interface. By merging these communication paths, the system reduces the amount of wiring required while ensuring that security authentication and temperature monitoring both use the same reliable wired connection
2Reliability
If separate interfaces are provided for security devices and temperature sensors, then reliability is improved, but device complexity increases
Solution Approach 1:
The second interface is designed as a universal communication interface that can operate in different modes. During authentication, it communicates with security devices; during normal operation, it communicates with temperature sensors. This eliminates the need for separate dedicated interfaces while maintaining communication reliability through consistent wired connectivity
Solution Approach 2:
The interface dynamically switches between different communication roles based on operational mode. The second interface adapts its function from security device communication to temperature sensor communication, providing reliability through a single robust interface design while avoiding the complexity of multiple static interfaces
3Device complexity
If wireless security devices are used, then device complexity is reduced, but reliability deteriorates due to interfering influences
Solution Approach 1:
The second interface serves dual purposes: authentication with security devices and temperature monitoring. By using this existing multi-functional wired interface for both purposes, the system achieves reliable communication without the need for additional wireless hardware, thus maintaining robustness while avoiding increased complexity
