Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning is performed, then labor and time are required, but cleaning quality is incomplete and removal of cleaning liquid may be incomplete
Solution Approach 1:
The cleaning device enables self-service cleaning of the liquid injection member through automated spraying mechanisms. The cleaning liquid is automatically sprayed onto the liquid injection member by the cleaning unit, eliminating the need for manual cleaning operations while ensuring consistent and complete cleaning coverage.
Solution Approach 2:
The patent replaces manual mechanical cleaning with an automated spraying system. The cleaning unit utilizes fluid dynamics to spray cleaning liquid onto the liquid injection member, substituting human-operated mechanical cleaning with a more reliable automated fluid-based system that ensures complete coverage and removal of cleaning liquid.
2Productivity
If automated cleaning is implemented, then cleaning efficiency is improved, but device complexity increases
Solution Approach 1:
The cleaning device is designed with multi-functionality to reduce overall system complexity. The cleaning unit serves multiple purposes: spraying cleaning liquid, removing electrolyte crystallization, and facilitating inspection. The base structure supports both the liquid injection member and the cleaning unit, creating a compact integrated system that achieves high cleaning efficiency without excessive complexity.
Solution Approach 2:
The inspection unit acts as an intermediary between the cleaning unit and the control system. It detects the spraying condition of the cleaning liquid and provides feedback to ensure proper cleaning operation, enabling automated control without requiring complex direct sensing and control mechanisms.
3Measurement precision
If cleaning liquid spraying is monitored, then spraying condition can be inspected, but measurement and detection complexity increases
Solution Approach 1:
The inspection unit utilizes color changes or visual indicators to detect the spraying condition of the cleaning liquid. By observing changes in the appearance, distribution, or pattern of the sprayed cleaning liquid, the system can assess whether proper cleaning is occurring without requiring complex sensors or measurement devices.
