Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for disconnecting aluminum pole pieces in decommissioned battery modules are inefficient, labor-intensive, and pose safety hazards due to manual operation and the use of resin saw blades, which wear quickly and are costly, leading to suboptimal cutting effects and potential fire risks.
Innovation Solution
A device comprising a stand with a workbench and an adjustable angle grinding device equipped with a polishing shaft and saw blades, allowing for simultaneous cutting of multiple electrodes with improved safety and efficiency, using metal saw blades and enabling adjustable spacing for different module sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tools (pliers, shovels, angle grinder) are used to disconnect pole pieces, then the disconnecting operation can be performed, but the operation speed is slow, labor intensity is high, and the disconnecting effect is poor
Solution Approach 1:
The patent replaces manual mechanical tools (pliers, shovels, hand-held angle grinder) with an automated mechanical cutting device that uses a rotating cutting blade to automatically cut through the aluminum pole pieces. The device includes a cutting blade rotating at high speed that can sever multiple pole pieces simultaneously, eliminating the need for manual prying and cutting operations.
Solution Approach 2:
The patent divides the disconnecting operation into separate functional components: a cutting blade for severing pole pieces, a support table for positioning battery modules, and a dust collection system for removing debris. This segmentation allows each component to be optimized independently and improves overall operational efficiency.
2Ease of manufacture
If hand-held angle grinder with resin saw blade is used for cutting, then pole disconnecting can be achieved, but the resin saw blade wears quickly and needs frequent replacement, affecting working efficiency and increasing operation cost
Solution Approach 1:
The patent changes the material parameter of the cutting blade from resin (consumable, wears quickly) to metal (durable, reusable). The metal cutting blade can cut through aluminum pole pieces repeatedly without significant wear, eliminating the need for frequent replacements and maintaining consistent cutting performance throughout the operation.
Solution Approach 2:
The patent uses a metal cutting blade that replicates the cutting function of the resin saw blade but with superior durability. The metal blade serves as a more robust copy that maintains its cutting edge and structural integrity over extended use, unlike the consumable resin blade.
3Manufacturing precision
If milling cutter passes through gap between cathodes and anodes to mill aluminum pole pieces, then the pole pieces can be milled, but the milling cutter electrically connects cathodes and anodes causing short circuit and sparks
Solution Approach 1:
The patent extracts the harmful electrical connection function from the cutting operation. By using a cutting blade that severs pole pieces rather than a milling cutter that removes material, the device eliminates the risk of the tool itself creating an electrical bridge between cathodes and anodes. The cutting action separates rather than connects electrical components.
Solution Approach 2:
The patent introduces a dust collection system as an intermediary component that captures cutting debris and prevents it from creating conductive pathways between electrical terminals. The dust collection system acts as a protective mediator that maintains electrical safety during the cutting operation.
4Ease of operation
If manual prying method is used to disconnect pole pieces, then the operation can be performed, but it sometimes causes damage to the battery electrode itself
Solution Approach 1:
The patent replaces the mechanical prying action with a controlled cutting action. Instead of using levers and force to pry pole pieces loose (which can bend or damage electrodes), the rotating cutting blade cleanly severs the pole pieces at the connection point, preserving the integrity of the battery electrodes.
