Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the manufacturing process of secondary batteries, radical units often collide with the loading part due to high transfer speeds, leading to damage, quality issues, and safety risks such as short-circuit defects and explosions.
Innovation Solution
A system and method that includes a transfer part, a loading part, and an intake part to suction air in the opposite direction of the transfer direction within the loading part, reducing the initial speed of radical units and preventing collisions with the loading part, thereby minimizing folding short defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the transfer speed of radical units is increased to improve productivity, then the manufacturing efficiency is improved, but the radical units collide with the loading part causing damage and quality defects
Solution Approach 1:
The patent introduces air as an intermediary medium between the radical units and the loading part. By controlling air flow in the loading part, the air acts as a cushion that absorbs the kinetic energy of falling radical units, preventing direct collision with the loading part while allowing high-speed transfer to continue
Solution Approach 2:
The patent applies pneumatic control by using air flow generated through intake holes in the loading part. The controlled air flow creates a pneumatic cushion that reduces the impact speed of radical units, allowing high-speed transfer without collision damage
2Loss of time
If the transfer speed is increased to reduce process time, then the manufacturing cycle is shortened, but folding short defects occur due to collision damage
Solution Approach 1:
Air flow serves as a protective intermediary that prevents collision damage during high-speed transfer, thereby eliminating folding short defects while maintaining reduced process time
Solution Approach 2:
The patent implements prior cushioning by pre-establishing air flow in the loading part before radical units arrive. This beforehand cushioning protects the radical units from collision damage, preventing folding short defects while allowing high-speed operation

AI summary
A system and method for manufacturing a secondary battery, in which air is suctioned in an opposite direction of a transfer direction inside a loading part to prevent a radical unit, which freely drops at an initial speed in the transfer direction, from colliding with the loading part, thereby reducing folding short defects that occur in a subsequent process.The system for manufacturing the secondary battery includes a transfer part configured to transfer a radical unit, a loading part configured to allow the radical unit transferred by the transfer part to drop in a direction of gravity so as to load the radical unit, and an intake part configured to suction air inside an inner space of the loading part from a side surface of the loading part.
