Engineering Contradiction Analysis
1Quantity of substance
If thicker wires or more wires are used to handle increasing transmission capacitance and number of electrical devices, then signal transmission capability is improved, but the area occupied by wiring increases
Solution Approach 1:
The patent replaces the electrical wiring system with an optical communication system. Optical fibers transmit data as light signals, enabling high-capacity data transmission without the need for thick electrical wires or multiple cables. This substitution fundamentally changes the transmission medium from electrical conductors to optical waveguides, achieving high transmission capability with minimal space occupation.
Solution Approach 2:
The patent changes the transmission parameter from electrical signals to optical signals. By using light instead of electricity for data transmission, the system achieves vastly superior transmission capacity while reducing the physical dimensions of the transmission medium. Optical fibers have extremely small diameters compared to electrical wires, directly addressing the area reduction requirement.
2Area of stationary object
If optical fiber is used to reduce wiring area, then device size is reduced, but the optical fiber may be damaged or disconnected during rotation
Solution Approach 1:
The patent introduces a rotary joint mechanism that enables dynamic rotation while maintaining optical fiber connection. The rotary joint allows the optical fiber to rotate with the display unit without experiencing excessive bending stress or disconnection. This dynamic solution accommodates the rotational movement inherent in adjustable displays while protecting the fragile optical fiber.
Solution Approach 2:
The patent introduces a rotary joint as an intermediary component between the fixed optical fiber connection and the rotating display unit. This intermediary element absorbs the mechanical stress of rotation, allowing the optical fiber to remain relatively stationary while the display unit rotates around it. The rotary joint acts as a buffer that prevents direct stress transmission to the optical fiber.
