Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dryers for electrode substrates of rechargeable batteries face inconvenience in connecting the substrate from the inlet to the outlet during the initial stage and drying process, requiring additional guide rails or sprockets, which complicates the process.
Innovation Solution
A dryer design featuring fixed guide rolls, lifting guide rolls, driving rolls, and a shuttle that moves between the inlet and outlet, allowing the electrode substrate to be conveniently connected and dried by ascending and descending the lifting guide rolls to guide the substrate in a zigzag manner, supported by driving rolls and lifting guide rolls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional guide rails or sprockets and chains are provided to connect the electrode substrate from inlet to outlet, then the substrate connection is achieved, but the device complexity increases and operation becomes inconvenient
Solution Approach 1:
The guide rolls are made movable rather than fixed, allowing them to dynamically adjust their positions. The lifting guide rolls can move vertically between a lowered position (for substrate connection) and a raised position (for drying), while driving rolls move horizontally to engage with the substrate. This dynamic configuration eliminates the need for complex fixed guide rails or sprocket systems.
Solution Approach 2:
The guide rolls serve multiple functions: they guide the substrate during connection, support the substrate during drying, and can be repositioned to accommodate different operational stages. The same guide rolls that assist in substrate connection also serve as support structures during the drying process, reducing the need for separate dedicated components.
2Productivity
If the lifting guide rolls are raised to guide the substrate in zigzag manner, then the drying effectiveness is improved, but the device complexity increases
Solution Approach 1:
The lifting guide rolls are positioned on vertically movable supports that can raise and lower the rolls. During the drying stage, the rolls are raised to create the zigzag path that enhances drying effectiveness. The same vertical movement mechanism that enables connection convenience also provides the zigzag drying path, achieving multiple benefits without adding separate complex mechanisms.
