Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stamp core packaging with embossing nubs is used to join laminations, then mechanical connection strength is improved, but electrical contact between neighboring laminations occurs causing iron losses and reduced efficiency
Solution Approach 1:
The invention extracts and eliminates the harmful embossing nubs from the lamination structure by using adhesive points instead, thereby removing the source of electrical contact between laminations while maintaining mechanical connection through adhesive bonding
Solution Approach 2:
The invention introduces an adhesive medium as an intermediary substance between laminations to achieve mechanical connection without direct metal-to-metal contact, preventing electrical contact and associated iron losses
2Manufacturing precision
If adhesive packaging with complex distribution and dosing systems is used to apply adhesive medium, then adhesive application precision is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The invention extracts and removes the complex distribution and dosing systems from the adhesive application device, replacing them with a simplified structure that achieves precise adhesive application through alternative means
Solution Approach 2:
The adhesive medium is applied in a manner that allows the system to self-regulate adhesive flow and placement without complex control mechanisms, reducing device complexity while maintaining application precision
3Adaptability or versatility
If adhesive packaging with movable components in application head is used to apply adhesive points, then adhesive application flexibility is improved, but contamination risk and maintenance intensity increase
Solution Approach 1:
The invention extracts and removes movable components from the application head, eliminating the source of contamination and maintenance issues while achieving adhesive application flexibility through alternative design
Solution Approach 2:
The invention segments the adhesive application system into stationary components, separating the adhesive supply mechanism from the application head to eliminate movable parts that cause contamination and maintenance requirements
