Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste collection methods for lithium ion cell electrode tabs, such as the waste free-falling method, crushing machine, and vacuum suction, face issues like poor cutting quality, safety risks, and blockages due to uneven negative pressure, making the third method widely used but prone to material absorption and pipeline blockages.
Innovation Solution
A waste collecting device comprising a frame, waste buffer box, negative pressure flow-equalizing box, and waste collecting box, with a negative pressure flow-equalizing box to equalize gas flow and prevent blockages by balancing negative pressure, ensuring smooth waste collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a waste machine is used to suck waste into the waste box and compress it, then waste collection efficiency is improved, but local negative pressure becomes too large causing waste to block the pipeline opening
Solution Approach 1:
The waste collection system is divided into multiple independent suction channels, each with its own negative pressure source. This segmentation prevents any single channel from generating excessive negative pressure that could cause blockages, while maintaining overall collection efficiency through parallel operation of multiple channels.
Solution Approach 2:
Different regions of the waste collection box are equipped with different negative pressure sources according to their specific needs. The negative pressure is localized and adjusted independently in each region, ensuring that no single location experiences excessive negative pressure that would cause waste to block the pipeline opening.
2Speed
If negative pressure is increased to improve waste suction, then waste collection speed increases, but waste is absorbed and blocks the opening of the negative pressure pipeline
Solution Approach 1:
The single high-speed suction channel is divided into multiple parallel suction channels, each operating at moderate negative pressure. This maintains overall waste collection speed through parallel flow paths while preventing any single channel from generating enough negative pressure to cause waste absorption and blockage.
Solution Approach 2:
A flow control mechanism is introduced as an intermediary between the negative pressure source and the waste stream. This intermediary regulates the negative pressure to prevent excessive suction that would cause waste to be absorbed and block the pipeline opening, while still maintaining sufficient suction speed for efficient waste collection.
