Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional liquid injection equipment is used, then the structure is simple, but the degree of automation is low and labor cost is high
Solution Approach 1:
The liquid injection system is divided into multiple functional modules including rotary device, liquid preparation mechanism, injection mechanism, weighing devices, and control equipment. Each module performs a specific function, allowing the system to achieve high automation through coordinated operation of segmented components while maintaining manageable complexity through modular design.
Solution Approach 2:
The rotary device serves multiple functions: positioning batteries for injection, transporting batteries between stations, and enabling sequential processing. The liquid preparation mechanism not only prepares liquid but also integrates with the injection system. This multi-functionality reduces the need for separate dedicated equipment, achieving automation without proportionally increasing system complexity.
2Productivity
If traditional liquid injection equipment is used, then the device structure is simple, but production efficiency is low
Solution Approach 1:
The rotary device enables continuous processing by maintaining constant motion and sequential positioning of batteries through different stations. Multiple batteries can be processed simultaneously at different positions, eliminating idle time and achieving continuous production flow, which significantly improves productivity while the automated control manages the complexity.
Solution Approach 2:
The liquid preparation mechanism prepares the injection liquid in advance before the injection process begins. Batteries are positioned and prepared at the liquid preparation position before moving to the injection position, ensuring that all necessary preparations are completed beforehand, thereby streamlining the main production process and improving overall efficiency.
3Extent of automation
If manual operation is used, then the equipment is simple, but labor cost is high
Solution Approach 1:
The system incorporates automatic weighing devices that automatically measure battery weights before and after injection to determine liquid absorption. The control equipment automatically controls the rotary device, liquid preparation mechanism, and injection mechanism based on weighing results, eliminating the need for manual operation and significantly reducing labor costs while the automation handles the complexity.
4Productivity
If automatic liquid preparation and injection is implemented, then production efficiency improves, but system complexity increases
Solution Approach 1:
The liquid preparation mechanism and injection mechanism are merged into an integrated system where the liquid preparation position and injection position are part of the same rotary device sequence. The control equipment统一管理 both preparation and injection processes, allowing them to operate as a coordinated automated system that improves productivity while managing complexity through integration rather than separate independent systems.
