Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing inspection processes for sensing blocks in electric vehicle batteries are time-consuming, particularly due to the manual movement of objects to each processing device, which hampers mass production efficiency.
Innovation Solution
A sensing block inspection device is designed with a thermally fused and laser-welded setup mounted on a battery module, featuring a turntable that rotates a jig member with the sensing block, allowing for sequential insulation resistance, heat-fusion, laser-welding, energization inspection, vision inspection, and barcode adhesion, thereby streamlining the inspection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual movement of sensing blocks to each processing device is used, then operator flexibility is maintained, but inspection time increases and mass production efficiency decreases
Solution Approach 1:
Multiple inspection devices (insulation resistance inspection, energization inspection, vision inspection) are merged into a single integrated inspection device with a common workbench and control unit, enabling simultaneous or sequential inspections without manual intervention
Solution Approach 2:
The inspection device performs multiple inspection functions (insulation resistance, energization, vision) through a single multi-functional system that can inspect different aspects of the sensing block without requiring separate dedicated devices for each inspection type
2Measurement precision
If multiple inspection processes are performed sequentially on separate devices, then each inspection can be performed with specialized equipment, but the overall inspection time and process complexity increase
Solution Approach 1:
Multiple specialized inspection functions are combined into one integrated device that maintains the precision of each inspection type while reducing the complexity of coordinating multiple separate devices and processes
Solution Approach 2:
A single inspection device is designed to perform multiple inspection types (insulation resistance measurement, energization testing, vision inspection) with unified control, maintaining measurement precision for each function while simplifying the overall process
