Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual hinge mechanisms are used for screen folding, then structural simplicity is maintained, but automation and efficiency are reduced
Solution Approach 1:
The patent replaces traditional mechanical hinge structures with electromagnetic driving apparatuses that use electromagnetic fields to achieve screen folding and angle adjustment. This substitution eliminates complex mechanical linkages while enabling automated control, directly resolving the contradiction between automation and structural complexity
Solution Approach 2:
The magnetic assemblies automatically attract or repel each other based on electrical signals to adjust screen angles without requiring manual intervention. The system serves itself by using electromagnetic forces to perform the adjustment function that would otherwise require mechanical operation or human input
2Volume of moving object
If traditional magnetic connectors are used, then connection function is achieved, but internal space is occupied
Solution Approach 1:
The patent divides the magnetic connection function into separate magnetic assemblies positioned at different locations (first magnetic assembly on first screen, second magnetic assembly on second screen). These segmented magnetic components work together through electromagnetic interaction to achieve angle adjustment without requiring a single bulky connector, thus saving internal space while maintaining operational ease
Solution Approach 2:
The patent transitions from traditional mechanical connection in three-dimensional space to electromagnetic field interaction that operates across spatial separation. The magnetic assemblies interact through magnetic fields rather than direct physical contact, enabling compact design while preserving the full range of motion and adjustment capability
