Split Protective Cover for Battery Ventilation in Harsh Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery housing ventilation devices in harsh environments face impaired ventilation functions due to exposure, and existing solutions lack efficient protection and easy mounting/dismounting procedures.
Innovation Solution
A protective cover with a radially extending flange portion and split, releasable parts that form an airflow duct, allowing attachment to a ventilation device's flange, providing a robust and flexible sealing mechanism with optional protrusions and fastening means for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective cover is provided for the ventilation device, then protection against environmental hazards is improved, but device complexity increases
Solution Approach 1:
The protective cover is divided into at least two separate parts that can be releasably attached to each other, allowing the cover to be segmented for easier installation and removal while still providing complete protection when assembled
Solution Approach 2:
The attachment portion is designed to universally fit various ventilation device configurations through the flange portion, enabling the same protective cover design to be applied across different battery housing vent models
2Manufacturing precision
If the protective cover is made as a single piece, then manufacturing precision is improved, but ease of operation deteriorates due to difficult mounting and dismounting
Solution Approach 1:
The protective cover is divided into at least two separate parts that can be easily attached and detached, significantly improving ease of operation for mounting and dismounting while maintaining adequate manufacturing precision for each individual part
Solution Approach 2:
The protective cover transitions from a static single-piece design to a dynamic multi-part structure with releasable connections, allowing the system to adapt between secure protection mode and easy installation/removal mode
3Object-affected harmful factors
If the protective cover completely seals the airflow opening, then protection is improved, but ventilation function is impaired
Solution Approach 1:
The protective cover acts as an intermediary element that channels airflow through its integrated airflow duct, protecting the ventilation device from direct environmental exposure while maintaining reliable ventilation function through the ducted airflow path

AI summary
A protective cover for protecting a ventilation device of a battery housing. The protective cover includes an airflow duct extending between a first opening and a second opening, wherein the first opening of the airflow duct is arranged to be fluidly connected to the airflow opening of the ventilation device and wherein the second opening is arranged to be fluidly connected to the external environment, an attachment portion associated with the first opening for attaching the protective cover to the first flange portion so that the protective cover covers the airflow opening, wherein the attachment portion, when being attached to the first flange portion, extends around the airflow opening, The protective cover has at least two separate parts which are releasably attachable to each other and arranged so that the attachment portion can be split into at least two separate attachment sections to allow the protective cover to be attached to and released from the first flange portion.
