Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a valve core is used to control glue spraying, then the glue spraying amount can be adjusted, but the valve core wears down and causes inconsistent glue dot sizes
Solution Approach 1:
The patent extracts the valve core from the glue spreading system and replaces it with a glue spreading block that has a wear-resistant surface. The glue spreading block directly contacts the silicon steel sheet without wearing down, eliminating the root cause of inconsistent glue dot sizes while maintaining adjustable glue spraying capability through the spreading block's geometry.
Solution Approach 2:
The patent uses a disposable or replaceable glue spreading block with a wear-resistant surface instead of a durable valve core. The spreading block can be easily replaced when worn, and its simple geometry allows for consistent glue dot sizes without the complexity and wear issues of valve cores.
2Manufacturing precision
If the valve core jacking height changes due to wear, then the glue spraying cavity size changes, but this leads to poor glue spraying consistency
Solution Approach 1:
The patent removes the valve core and its associated jacking height instability from the system. The glue spreading block provides a stable, wear-resistant surface that maintains consistent geometry over time, ensuring uniform glue dot sizes without the dimensional instability inherent in valve cores.
3Manufacturing precision
If glue dots are made larger to ensure coverage, then glue may enter wire grooves, but this requires additional cleaning processes
Solution Approach 1:
The patent applies local quality by using a glue spreading block with a wear-resistant surface that provides precise, controlled glue spreading. The block's geometry ensures glue is deposited only where needed on the silicon steel sheet, achieving adequate coverage without excessive glue that would enter wire grooves and require additional cleaning.
4Productivity
If valve cores are used for multiple silicon steel sheets, then production efficiency should improve, but frequent maintenance reduces efficiency
Solution Approach 1:
The patent extracts the maintenance-prone valve core from the system and replaces it with a durable glue spreading block. The spreading block's wear-resistant surface allows it to serve many silicon steel sheets without frequent maintenance, thereby improving production efficiency.
Solution Approach 2:
The patent uses a simple, replaceable glue spreading block that can be easily replaced when worn. This disposable approach is more efficient than maintaining complex valve cores, as replacement is quick and the simple geometry ensures consistent performance throughout the block's service life.
