Vertical Battery Apparatus with Individual Cell Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery apparatus with integrally packed film-sheathed batteries requires heavy effort for installation and maintenance due to the large weight of the battery unit, necessitating the entire unit to be inserted or removed, and individual battery replacement is not feasible.
Innovation Solution
A battery apparatus with a housing that allows individual secondary batteries to be inserted and removed vertically in parallel, featuring a lid that opens and closes, enabling easier access and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If film-sheathed batteries are integrally packed in a box to form a battery unit, then the battery unit can be housed in a casing, but the battery unit has large weight requiring heavy effort for insertion and removal
Solution Approach 1:
The battery unit is divided into individual film-sheathed batteries that can be independently inserted and removed. Each battery maintains its film-sheathed structure while being separable from the assembly, allowing single battery replacement without handling the entire heavy unit.
2Difficulty of detecting and measuring
If the entire battery unit is removed from the casing for maintenance, then malfunctioning batteries can be identified, but the entire battery unit must be replaced even if only one battery is malfunctioning
Solution Approach 1:
The malfunctioning battery is extracted individually from the battery unit assembly. The design allows removal of only the defective battery while leaving functional batteries in place, enabling selective replacement rather than replacing the entire battery unit.
3Strength
If multiple workers are needed to insert or remove the battery unit, then the battery unit can be handled safely despite its weight, but the operation becomes more complex and time-consuming
Solution Approach 1:
The heavy battery unit is segmented into lighter individual batteries that can be handled by a single worker. Each film-sheathed battery has reduced weight compared to the complete unit, eliminating the need for multiple workers while simplifying the operation procedure.
