Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wire is buried in abrasive grains in a composite electroplating tank with small contact area, then abrasive grains can be fixed to the wire, but the electroplating time becomes long and the amount and distribution of abrasive grains cannot be controlled
Solution Approach 1:
The electroplating tank is divided into multiple compartments, each containing abrasive grains of different sizes or types. This segmentation allows the wire to pass through multiple compartments sequentially, increasing the contact area and enabling better control over the amount and distribution of abrasive grains fixed to the wire, while reducing the overall electroplating time required.
Solution Approach 2:
The wire is configured to pass through multiple compartments in a sequential manner, transforming the contact from a two-dimensional small area to a multi-dimensional extended contact path. This dimensional change increases the effective contact area between the wire and abrasive grains, improving both the fixation reliability and the controllability of grain distribution.
2Manufacturing precision
If high-temperature processing is used to fix abrasive grains by adhesive, then control over abrasive grains is good, but the wire and abrasive grains could be damaged and mechanical properties are jeopardized
Solution Approach 1:
The high-temperature adhesive bonding process is replaced with an electroplating process that occurs at lower temperatures. The electroplating mechanism uses electrical current to deposit metal and bind abrasive grains to the wire, achieving good control over grain placement without the need for high-temperature processing that could damage the wire or grains.
Solution Approach 2:
The processing temperature parameter is changed from high-temperature (adhesive method) to low-temperature (electroplating method). This parameter change maintains the ability to control abrasive grain placement while avoiding the damage and mechanical property degradation caused by high-temperature processing.
3Ease of manufacture
If free abrasive manner is used with abrasive paste, then slicing can be performed, but the efficiency and precision are low and abrasive paste consumption pollutes the environment
Solution Approach 1:
Abrasive grains are pre-fixed to the wire through electroplating before the slicing operation. This preliminary action ensures that the abrasive grains are securely attached and properly distributed on the wire, enabling efficient and precise slicing from the start without the need for abrasive paste during the cutting process, thereby improving productivity and reducing environmental pollution.
