Modular Tray for Secondary Battery Cell Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery cell activation trays require significant human labor and are economically inefficient due to the need to remove and reinsert defective cells, which reduces the efficiency of the activation process.
Innovation Solution
A modular activation tray system comprising multiple detachable module trays that allow for easy removal and reconfiguration, enabling the isolation and replacement of defective cells without removing the entire tray, thereby increasing efficiency and reducing labor costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional non-modular activation tray is used, then the tray can hold multiple battery cells, but when a defective cell is found the entire tray must be removed and reinserted, significantly increasing human labor and reducing activation process efficiency
Solution Approach 1:
The activation tray is divided into multiple detachable module trays, each capable of holding one or more battery cells. When a defective cell is detected, only the specific module tray containing the defective cell needs to be removed and replaced, rather than removing the entire activation tray. This segmentation dramatically reduces the time and labor required for handling defective cells and maintains high activation process efficiency.
2Reliability
If the entire activation tray is removed for defective cell replacement, then defective cells can be replaced, but continuous operation is disrupted and labor costs increase
Solution Approach 1:
By segmenting the activation tray into modular units, the system enables localized replacement of only the affected module tray when a defective cell is found. This allows continuous operation of other module trays simultaneously, minimizing operational downtime and maintaining high reliability of the overall activation process.
Solution Approach 2:
The modular design ensures that while one module tray is being replaced due to a defective cell, other module trays continue to operate without interruption. This continuity of useful action maintains high productivity and reduces the impact of defective cell management on overall process efficiency.
3Productivity
If a modular design with detachable module trays is implemented, then efficiency and labor cost reduction are achieved, but device complexity increases
Solution Approach 1:
While segmentation into modular trays does increase structural complexity compared to a conventional single-piece tray, the modular design uses standardized connection interfaces and uniform structures across modules. This standardization minimizes the actual complexity increase and provides benefits in terms of ease of assembly, maintenance, and scalability.
Solution Approach 2:
Each module tray is designed with universal characteristics - identical connection interfaces, uniform dimensions, and interchangeable functionality. This universality means that while the system is modular, the complexity is not multiplied across different types of modules, as all modules can perform the same function and use the same connection protocol, simplifying the overall system design.
