Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery racks face increased manufacturing costs and complex installation processes due to the need for custom-made connections for fire-fighting systems, which are exacerbated by varying outlet positions of extinguishing agent supply pipes.
Innovation Solution
A battery rack design featuring a flexible pipe with couplers and a branched injection pipe system that allows for adaptable connection to supply pipes, along with a passive valve for temperature-activated extinguishing agent release and a drain pipe for agent discharge, simplifying installation and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom-made transfer pipes are designed for each battery module according to supply pipe outlet positions, then fire suppression effectiveness is improved, but manufacturing costs increase
Solution Approach 1:
The transfer pipe is designed with a universal structure that can serve multiple battery modules simultaneously. The pipe includes multiple outlets that can be positioned to supply extinguishing agent to different battery modules, eliminating the need for custom-made pipes for each module and reducing manufacturing costs while maintaining fire suppression effectiveness
Solution Approach 2:
The transfer pipe is divided into multiple segments or outlets, each capable of supplying extinguishing agent to different battery modules. This segmented design allows a single pipe to replace multiple custom pipes, achieving both effectiveness and cost reduction
2Reliability
If pipe welding operations are performed to connect supply pipe to transfer pipe, then connection reliability is improved, but installation time and cost increase
Solution Approach 1:
A coupling device is introduced as an intermediary component between the supply pipe and transfer pipe. This coupling device provides a simple connection interface that eliminates the need for complex welding operations, reducing installation time and cost while maintaining reliable connection through the intermediary coupling mechanism
Solution Approach 2:
The welding operation (thermal/mechanical process) is replaced with a mechanical coupling system. The coupling device uses mechanical fastening methods such as threading, clamping, or bayonet-style connections, which are much faster and easier to install while providing sufficient connection reliability for the fire suppression application
