Ventilation Chamber Water Drainage and Intrusion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Energy storage apparatuses face challenges in efficiently draining water that enters the ventilation structure, leading to potential impairment of internal components and increased risk of water intrusion, especially when used outdoors.
Innovation Solution
The energy storage apparatus incorporates a ventilation chamber with a through hole, a back wall, a first wall, and a side wall with a gap, which attenuates water energy and promotes drainage, while also using a labyrinth structure and a waterproof gas-permeable film to prevent water intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ventilation chamber with through holes is provided to enable gas discharge, then ventilation function is improved, but water intrusion risk increases
Solution Approach 1:
The ventilation chamber is segmented into multiple functional zones: a first region with through holes for gas discharge, a second region with through holes at different positions for drainage, and a partition wall separating these regions. This segmentation allows the structure to simultaneously achieve ventilation functionality and water drainage capability, resolving the contradiction between maintaining gas discharge function and preventing water intrusion.
Solution Approach 2:
A waterproof breathable film is introduced as an intermediary element that selectively permits gas molecules to pass through while blocking water molecules. This film is positioned strategically within the ventilation chamber to maintain ventilation function while preventing water intrusion, effectively mediating between the conflicting requirements of gas discharge and water protection.
2Productivity
If water drainage capability is enhanced through structural modifications, then water removal efficiency is improved, but device complexity increases
Solution Approach 1:
The partition wall serving as a structural divider is simultaneously equipped with through holes that function as drainage pathways. This multi-functional design allows the same structural element to serve both as a separator and as an active component for water drainage, thereby improving drainage efficiency without proportionally increasing device complexity.
Solution Approach 2:
Through holes are positioned at multiple spatial dimensions within the ventilation chamber - including vertical positioning on the partition wall and horizontal positioning on chamber surfaces. This multi-dimensional arrangement of drainage openings enables efficient water removal through various pathways without requiring a single complex drainage system, thus improving productivity while managing structural complexity.

AI summary
An energy storage apparatus includes an outer case, and an energy storage device housed in an inside of the outer case. The outer case includes a ventilation chamber which makes the inside and an outside of the outer case communicate with each other. The ventilation chamber includes a front wall in which a through hole communicating with the outside is formed, a back wall disposed at a position where the back wall opposedly faces the front wall, a first wall disposed between the through hole and the back wall, and a first side wall disposed in an extending manner along a first direction which intersects with the front wall with a gap formed between the first side wall and the first wall. The gap is formed over a distance from the front wall to the back wall along the first direction.
