Energy Storage Device Wireless Commissioning via QR Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commissioning of electrical energy storage devices, particularly in domestic applications, is cumbersome due to the need for manual settings and complex configurations involving PC systems and serial interfaces, which limits flexibility and efficiency.
Innovation Solution
The integration of a communication interface for wireless data access, including a QR code with authentication data, allows for flexible commissioning through mobile devices, enabling seamless connection to networks and cloud services, simplifying the setup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If PC systems with serial interfaces are used for commissioning, then data transfer and configuration are possible, but the commissioning process becomes complex and inflexible
Solution Approach 1:
The patent replaces the mechanical/physical connection system (PC via USB or serial cable) with a wireless communication system. The storage device creates its own Wi-Fi network, allowing commissioning via wireless connection instead of requiring physical cable connections and dedicated PC systems.
Solution Approach 2:
The patent introduces a wireless communication interface as an intermediary between the storage device and the commissioning device. This intermediary enables data transfer and configuration without requiring direct physical connections, simplifying the commissioning process.
2Productivity
If manual settings are performed during commissioning, then configuration is possible, but time and effort are required
Solution Approach 1:
The storage device provides self-service capabilities by creating its own wireless network and providing authentication credentials (QR code or Wi-Fi password) that enable automatic connection and configuration. This eliminates the need for complex manual setup procedures.
Solution Approach 2:
The storage device performs preliminary actions by pre-configuring its wireless communication interface and generating authentication credentials before the commissioning process begins. This allows the commissioning device to connect automatically without requiring manual configuration steps.
3Adaptability or versatility
If wireless data access is provided, then flexibility and ease of commissioning are improved, but authentication and security measures are required
Solution Approach 1:
The patent uses QR codes as a simplified copy/representation of authentication credentials. Instead of requiring users to manually enter complex Wi-Fi passwords or configuration data, the authentication information is encoded in a QR code that can be scanned and automatically processed.
