1Area of stationary object
If signal lines are arranged on a traditional circuit board layout, then electrical connectivity is achieved, but the circuit board size increases and space utilization decreases
Solution Approach 1:
The circuit board is divided into distinct functional regions: a body part containing the driving chip, a pad part for external connections, and a line part for signal routing. This segmentation allows each region to be optimized independently, reducing overall board area while maintaining functionality.
Solution Approach 2:
The line part is designed to extend in a first direction from the body part and can be bent along a bending line. This dimensional flexibility allows signal lines to route efficiently through three-dimensional space rather than being constrained to a flat two-dimensional layout, reducing the required board area.
2Ease of operation
If the circuit board size is reduced for compactness, then space utilization improves, but signal line arrangement becomes more difficult
Solution Approach 1:
By separating signal routing into a dedicated line part distinct from the pad part and body part, the design simplifies signal line arrangement. The line part can be independently configured to connect pads to the driving chip without interfering with other components, making routing easier even on compact boards.
Solution Approach 2:
The line part is designed with bendability along a bending line, allowing the signal lines to adapt their path dynamically. This flexibility enables efficient routing on reduced-size boards by allowing lines to bend and route around obstacles or optimize paths, simplifying the arrangement process.
3Ease of operation
If the line part is made bendable to improve layout flexibility, then space utilization increases, but structural stability may decrease
Solution Approach 1:
The circuit board is segmented into a rigid body part and a flexible line part. The body part maintains structural stability and houses the driving chip, while the line part provides the necessary flexibility for routing. This segmentation allows each part to fulfill its primary function without compromising the other.
Solution Approach 2:
Different parts of the circuit board have different mechanical properties: the body part is structurally stable for component mounting, while the line part is bendable for routing flexibility. This local differentiation of material or structural properties allows the overall system to achieve both stability and flexibility where needed.
