Battery Waste Immersion Layout for Reactive Scrap Neutralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of battery cells generates waste that poses safety hazards due to its chemical activity, particularly lithium and sodium-containing waste, which can react with water and oxygen, leading to spontaneous combustion or explosion, and existing disposal methods are inefficient and unsafe.
Innovation Solution
A disposal system and method that includes a moving mechanism, accommodating mechanisms, and a transfer mechanism to immerse waste in a specific liquid, either chemically reacting with or physically wrapping the waste to render it inert, while also incorporating a drying mechanism for recycling and an exhaust mechanism to prevent gas leakage, thereby enhancing safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waste is disposed of using existing methods, then disposal is performed, but safety hazards increase due to chemical activity of lithium and sodium-containing waste
Solution Approach 1:
The patent applies the inert atmosphere principle by immersing hazardous waste in a liquid medium that creates an inert environment, preventing lithium and sodium-containing waste from reacting with water and oxygen in the air, thereby eliminating spontaneous combustion and explosion risks during disposal
Solution Approach 2:
The patent converts the harmful chemical activity of waste into a beneficial process by using controlled chemical reactions between the waste and immersion liquid, transforming hazardous materials into safe, stable compounds through deliberate chemical interaction
2Area of stationary object
If multiple accommodating mechanisms are arranged along width direction, then space occupancy is reduced, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the waste disposal system into multiple independent accommodating mechanisms arranged along the width direction, allowing parallel processing of waste while maintaining modular simplicity that reduces overall system complexity
Solution Approach 2:
The patent resolves the space-complexity contradiction by transitioning from a single linear arrangement to a multi-dimensional layout where multiple accommodating mechanisms are arranged along the width direction, enabling parallel operations without significantly increasing system complexity
3Productivity
If immersion mechanisms are moved between accommodating mechanisms, then disposal efficiency is improved, but mechanism complexity increases
Solution Approach 1:
The patent applies dynamics by making immersion mechanisms movable between accommodating mechanisms, enabling flexible allocation and parallel processing that improves disposal efficiency while using simple guiding structures that minimize added complexity

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 system effectively neutralizes hazardous waste by chemically reacting or physically wrapping it, improving safety in the battery production process and reducing space occupancy through efficient waste disposal and recycling, while preventing gas leakage and enhancing overall safety performance.
Implementation Method 1
a chemical reaction takes place between the waste and the immersion liquid to reduce activity of the waste
Implementation Method 2
The waste is physically wrapped by the immersion liquid and becomes inert
