Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a valve core is used to spray glue continuously, then the glue spraying function is maintained, but the valve core wears quickly and requires frequent maintenance
Solution Approach 1:
The patent replaces the traditional valve core with a glue spreading block made of wear-resistant material. Although the spreading block is designed to be replaceable, its wear-resistant construction significantly extends service life compared to conventional valve cores, reducing maintenance frequency while maintaining continuous spraying capability
Solution Approach 2:
The patent changes the material parameter of the glue application component from standard valve core material to wear-resistant material, fundamentally improving durability and service life while maintaining the continuous glue spraying function
2Duration of action of moving object
If the valve core jacking height changes due to wear, then the valve core continues to function, but the glue dot size becomes inconsistent
Solution Approach 1:
The glue spreading block is designed as a replaceable component with wear-resistant properties. When wear occurs, the entire block can be replaced rather than requiring precision adjustment, ensuring consistent glue dot sizes throughout its extended service life
Solution Approach 2:
The patent changes from a metal valve core subject to dimensional changes to a wear-resistant spreading block where wear is minimized, maintaining consistent glue application parameters throughout the component's operational life
3Manufacturing precision
If glue dots are made larger to ensure coverage, then better bonding is achieved, but glue enters the wire groove and affects winding process
Solution Approach 1:
The glue spreading block features a localized glue outlet structure that precisely controls glue deposition. The block's geometry and outlet positioning ensure glue is deposited only in the required area, preventing overflow into wire grooves while maintaining adequate bonding coverage
Solution Approach 2:
The wear-resistant glue spreading block acts as an intermediary between the glue supply system and the silicon steel sheet. It precisely mediates glue transfer, controlling the glue dot size and placement to achieve proper coverage without contaminating adjacent areas
4Ease of manufacture
If traditional valve cores are used for glue spraying, then glue application is achieved, but frequent maintenance is required affecting production efficiency
Solution Approach 1:
The replaceable wear-resistant glue spreading block eliminates the need for frequent maintenance of traditional valve cores. Its extended service life reduces production downtime and maintenance costs, improving overall production efficiency while maintaining glue spraying capability
Solution Approach 2:
The patent changes the material composition and wear characteristics of the glue application component, transforming it from a frequently replaced valve core to a durable spreading block that maintains performance throughout extended operational periods, thereby improving production efficiency
