Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The discharge of gas and smoke from power storage modules can be hindered by foreign matter when exhausted downward, leading to reduced exhaust efficiency and potential damage due to increased internal pressure.
Innovation Solution
A power storage device design featuring a power storage module with an exhaust hole, a lower case with a recessed portion and a partition member containing a flue gas path, allowing efficient discharge of gases and smoke through a flue gas path formed by recessed grooves and partition members, preventing foreign matter accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If gas and smoke are discharged downward from the power storage module, then the exhaust structure is simplified, but foreign matter accumulates under the module and hinders exhaust efficiency
Solution Approach 1:
The patent introduces a recessed portion that creates a three-dimensional space beneath the power storage module, transforming the exhaust path from a direct downward discharge into a multi-level flow path. This dimensional change allows gas and smoke to be directed into the recessed space and then channeled through the flue gas path, preventing foreign matter accumulation while maintaining exhaust efficiency without complicating the overall structure
Solution Approach 2:
The recessed portion acts as an intermediary space between the exhaust hole and the external environment. It receives gas and smoke discharged downward from the power storage module and facilitates their movement through the flue gas path, preventing direct contact between exhaust gases and foreign matter on the bottom surface while maintaining a relatively simple exhaust structure
2Volume of stationary object
If foreign matter accumulates under the power storage module, then the space utilization is maximized, but the exhaust of gas and smoke is hindered
Solution Approach 1:
The patent segments the space under the power storage module by introducing a recessed portion and flue gas path, creating distinct functional zones. The recessed portion collects exhaust gases while the flue gas path channels them away, preventing foreign matter from blocking the exhaust flow while maintaining efficient space utilization within the lower case
Solution Approach 2:
The recessed portion is strategically positioned at specific locations beneath the power storage module to create localized exhaust collection zones. This local modification allows foreign matter to be excluded from critical exhaust paths while maintaining overall space utilization, ensuring reliable exhaust function without sacrificing volume efficiency
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively directs gas and smoke away from foreign matter, enhancing exhaust efficiency and preventing damage from increased pressure, thus maintaining optimal operational conditions.
Implementation Method 1
a flue gas path that communicates with the recessed portion is provided inside the partition member... the gas and the smoke discharged from an exhaust port provided in the lower surface of the power storage module are discharged to the recessed portion that communicates with the flue gas path inside the partition member

AI summary
The power storage device includes a power storage module including a lower surface on which an exhaust hole is formed, a lower case including a bottom surface portion covering a lower surface of the power storage module from below, and a cross member (partition member) provided in the lower case so as to partition a region in which the power storage module is disposed in the lower case. A groove portion (recessed portion) recessed downward is formed in the bottom surface portion. A flue gas path communicating with the groove portion is formed inside the cross member.
