Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Material waste and high manufacturing costs occur during battery production due to temperature inconsistencies between the heating device and the first station, leading to unsatisfactory process temperatures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heating device is positioned far from the first station, then the heating module has sufficient space for operation, but the material strip temperature becomes inconsistent by the time it reaches the first station
Solution Approach 1:
The heating module is designed to be movable along the feeding direction of the material strip through a driving mechanism. This allows the heating device to dynamically adjust its position - moving closer to the first station when high temperature consistency is needed, and moving away when space is required, thus resolving the contradiction between temperature consistency and distance
Solution Approach 2:
The heating module performs preliminary heating of the material strip before it reaches the first station. By positioning the heating device upstream and adjusting its distance, the material strip is preheated to the required temperature, ensuring temperature consistency when it arrives at the first station
2Temperature
If the first heating module is positioned close to the first station, then temperature consistency is improved, but the available space for the heating device is reduced
Solution Approach 1:
The heating module's position is made dynamic rather than fixed. It can move closer to the first station when temperature consistency is the priority, and move away when more space is needed for device operation or maintenance, thus resolving the spatial contradiction
3Productivity
If a single high-power heating unit is used, then heating efficiency is improved, but the risk of excess temperature and material damage increases
Solution Approach 1:
The heating function is divided into multiple heating units (first heating unit and second heating unit) with different power levels. The second heating unit with higher power provides rapid heating, while the first heating unit with lower power provides gentle heating. This segmentation allows flexible combination to achieve efficient heating without excessive temperature
Solution Approach 2:
Different heating units are assigned different power levels according to their specific positions and functions. The second heating unit closer to the first station has higher power for rapid heating, while the first heating unit upstream has lower power for gradual preheating, optimizing heating quality at different locations
4Manufacturing precision
If multiple heating units with different powers are used, then temperature control precision is improved, but the device complexity increases
Solution Approach 1:
The heating system is segmented into multiple independent heating units, each with controllable power output. This allows precise temperature control by activating individual units or combinations thereof, achieving high temperature precision while maintaining manageable system complexity through modular design
