Solution Overview
Problem
Fire protection doors require reliable electrochemical energy storage systems, but existing solutions face challenges in ensuring correct installation and storage without causing issues during transportation and assembly, particularly due to the risk of untested batteries leading to unknown fire behavior.
Innovation Solution
A locking device with at least two storage groups, each containing electrochemical energy stores and an integration element for mechanical and electrical coding, allowing only authorized assembly and ensuring correct energy storage usage, while enabling safe storage and transport by maintaining electrical isolation during these phases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple electrochemical energy stores are assembled into a single battery pack, then the door device can operate reliably with sufficient energy, but storage and transportation become problematic due to safety concerns
Solution Approach 1:
The battery system is divided into multiple separate storage groups instead of assembling all electrochemical energy stores into a single battery pack. Each storage group contains one or more electrochemical energy stores and can be handled, stored, and transported independently, eliminating the safety concerns associated with transporting large assembled battery packs while ensuring sufficient total energy capacity for reliable door device operation
2Reliability
If the correct prescribed batteries are installed in the door device, then fire protection reliability is ensured, but the risk of incorrect battery installation cannot be eliminated
Solution Approach 1:
The integration elements of the storage groups are designed with asymmetric coding features that must match corresponding receptacles in the door device. This asymmetric design creates a mechanical constraint that allows only the correct prescribed batteries to be installed in the proper orientation, physically preventing incorrect battery installation while maintaining ease of operation through intuitive alignment
Solution Approach 2:
Integration elements serve as intermediary components between the electrochemical energy stores and the door device. These integration elements contain coding features that mediate the connection, ensuring that only compatible, prescribed batteries can be installed. The integration elements translate the battery identification code into a mechanical fit, guaranteeing fire protection reliability without complicating the installation process
3Reliability
If storage groups are electrically isolated during transport, then safety is improved, but electrical connection complexity increases
Solution Approach 1:
The electrical connection system transitions dynamically between two states: during transport, storage groups remain electrically isolated (static safe state); during installation, the integration elements automatically establish electrical connections when the storage groups are inserted into the door device (dynamic operational state). This dynamic approach maintains safety during transport while minimizing connection complexity through automatic engagement mechanisms
