Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional sensors are integrated to detect partial orientations of screen display areas, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The hinge structure serves multiple functions: it provides the mechanical folding mechanism for the flexible display while simultaneously acting as an electromagnetic field transmission path for orientation detection. The hinge plates are configured to transmit electromagnetic fields between the first and second housings, enabling the existing hinge components to perform both structural and sensing functions, thereby avoiding additional sensor integration complexity.
Solution Approach 2:
The hinge plates act as intermediary elements that transmit electromagnetic fields between the housing components. By incorporating electromagnetic field transmission capabilities into the hinge structure itself, the patent creates a mediator that enables orientation detection without requiring separate sensor components, thus improving measurement precision while maintaining device simplicity.
2Measurement precision
If electromagnetic sensor and member are added to detect electromagnetic fields, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the electromagnetic field transmission function with the hinge structure. The hinge plates are designed to both provide mechanical coupling and transmit electromagnetic fields, combining two functions into a single component. This integration eliminates the need for separate electromagnetic sensors and members, thereby reducing manufacturing costs while maintaining detection accuracy.
Solution Approach 2:
The hinge structure is designed to serve dual purposes: mechanical support for the flexible display and electromagnetic field transmission for orientation detection. By making the hinge plates universal components that perform both structural and electromagnetic functions, the patent avoids the need for additional specialized components, thus reducing manufacturing complexity and cost.
3Measurement precision
If electromagnetic field transmission is enhanced through hinge plates, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The hinge structure utilizes the existing mechanical movement and electromagnetic field generation inherent in the flexible display operation to achieve orientation detection. The hinge plates transmit electromagnetic fields passively through their mechanical positioning, leveraging the self-motion of the display system rather than requiring active power-consuming sensors, thus achieving precise measurement with minimal power consumption.
