Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional coating method is used to apply punching oil to uncoated portions, then the coating process can be completed, but the coating becomes uneven and leads to issues during notching
Solution Approach 1:
The coating device applies punching oil to the uncoated portions of the electrode plate before the notching process begins. The feed rollers press the uncoated portions against the coating device to ensure uniform coating distribution prior to notching, preventing coating-related issues during the subsequent notching operation.
Solution Approach 2:
The coating device is specifically designed to coat only the uncoated portions of the electrode plate where punching oil is needed. The feed rollers selectively press these uncoated portions against the coating device, ensuring that punching oil is applied precisely where required without affecting already coated areas, thus achieving uniform local coating quality.
2Productivity
If manual or simple coating methods are used, then the equipment complexity is low, but the coating efficiency and uniformity are insufficient
Solution Approach 1:
The coating device is integrated with the feed rollers that already exist in the notching apparatus. The feed rollers serve dual functions: conveying the electrode plate and pressing uncoated portions against the coating device. This merging of functions increases coating efficiency without proportionally increasing overall system complexity.
Solution Approach 2:
The feed rollers are designed to perform multiple functions: electrode plate conveyance, pressing uncoated portions against the coating device for uniform coating application, and potential positioning functions. This multi-functionality improves coating efficiency while avoiding the need for separate dedicated coating mechanisms, thus limiting the increase in device complexity.

Implementation Method 1
a sprayer configured to spray the punching oil onto the coating device
Implementation Method 2
the coating roller is configured such that it may coat the at least one of the uncoated portions with the punching oil by a rotation contact with the at least one of the uncoated portions
Implementation Method 3
a coating roller rotatably coupled to the support rod that passes through a central portion of the coating roller, the coating roller having a surface in which the punching oil is impregnated
Implementation Method 4
as the feed rollers press the pair of uncoated portions against the coating device and move the electrode plate
