Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display modules are connected using traditional mechanical fastening methods, then the connection strength is sufficient, but the folding and unfolding operations become complex and difficult
Solution Approach 1:
The patent replaces traditional mechanical fastening systems with a magnetic coupling system. Magnets are embedded in the coupling guides, which automatically attract and hold display modules together through magnetic force during unfolding, and allow easy separation during folding. This eliminates complex mechanical fasteners while maintaining secure connections.
Solution Approach 2:
The coupling guides with embedded magnets perform self-alignment and self-locking functions. When display modules are brought together during unfolding, the magnetic force automatically guides them into proper alignment and secures them without requiring manual intervention or complex locking mechanisms. The system serves itself through the inherent properties of the magnetic coupling.
2Reliability
If multiple display modules are connected with complex coupling mechanisms, then the connection reliability is high, but the installation process becomes time-consuming and complicated
Solution Approach 1:
The patent replaces time-consuming mechanical fastening operations with instantaneous magnetic coupling. During installation, display modules are simply brought near each other and the magnetic force in the coupling guides automatically secures them, reducing installation time from minutes per connection to seconds while maintaining reliable connections.
Solution Approach 2:
The magnets are pre-installed within the coupling guides during manufacturing, so that when display modules are installed, the magnetic coupling mechanism is already prepared and ready to engage immediately. This preliminary preparation eliminates the need for on-site assembly of complex fastening mechanisms.
3Area of stationary object
If display modules are kept in a compact folded state, then the space requirement is minimized, but the usable screen area is not available
Solution Approach 1:
The patent creates a dynamic display system where the display modules can transition between folded and unfolded states. The magnetic coupling guides enable smooth, controlled transitions that allow the display to adapt its configuration based on usage requirements, transforming from a compact storage state to a full-screen operational state.
Solution Approach 2:
The display system is divided into multiple independent display modules that can be individually controlled and positioned. This segmentation allows the display to be folded into compact segments for space efficiency, and unfolded into a large continuous screen when full display area is needed, with each module maintaining its own coupling guide for independent operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
