Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery module manufacturing processes involve separate heating and cooling stages, leading to increased overall production time and inefficiency due to long hardening times and additional cooling processes, which cause temperature deviations and process congestion.
Innovation Solution
A battery module manufacturing apparatus with a thermoelectric device that can switch between heating and cooling functions, using a Peltier element to control temperature and integrate both processes in a single apparatus, reducing hardening time and eliminating the need for separate cooling steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate high-temperature hardening apparatus and cooling apparatus are used, then adhesive hardening is achieved and temperature uniformity is improved, but manufacturing process time is lengthened and production efficiency decreases
Solution Approach 1:
The patent combines the heating function and cooling function into a single base jig, eliminating the need for separate hardening apparatus and cooling apparatus. The base jig integrates a heater for high-temperature hardening and a cooler for subsequent cooling, allowing both processes to occur in one stationary position rather than requiring multiple separate apparatus and process steps.
Solution Approach 2:
The base jig is designed with multi-functionality, serving both as a heating device during the adhesive hardening phase and as a cooling device during the cooling phase. This universal device performs multiple functions that previously required separate specialized apparatus, thereby simplifying the overall manufacturing system and reducing process time.
2Reliability
If multiple separate processes (fixation, hardening, cooling) are performed at different positions, then each process is completed properly, but overall process configuration becomes complicated and total production time increases
Solution Approach 1:
The patent merges the fixation process, hardening process, and cooling process into a single integrated operation at one stationary position. The battery module is fixed to the base jig once, and all subsequent processes (heating for hardening, then cooling) are performed while the module remains in the same location, eliminating the need to move the module between different process positions and apparatus.
Solution Approach 2:
The base jig is segmented into distinct functional components (heater, cooler, battery module receiving portion) that can independently perform their respective functions. This segmentation allows the system to execute multiple processes sequentially at the same location without requiring complex reconfiguration or movement between different apparatus.
3Loss of energy
If adhesive hardening is performed at room temperature, then energy consumption is reduced, but hardening time extends to about 24 hours making the process impractical
Solution Approach 1:
The patent changes the temperature parameter during the hardening process by using the integrated heater in the base jig to raise the temperature to a range of 50°C to 200°C. This parameter change accelerates the adhesive hardening reaction, reducing the hardening time from 24 hours at room temperature to a practical duration while maintaining proper adhesive bonding.
Solution Approach 2:
The manufacturing process uses periodic action by first applying high temperature for a predetermined time to complete the hardening process, then switching to cooling mode. This structured temporal sequence of heating followed by cooling optimizes both the hardening efficiency and the subsequent cooling requirements.
