1Volume of moving object
If a conventional flat connection circuit board is used, then electrical connection is achieved, but the space occupied by the circuit board increases
Solution Approach 1:
The connection circuit board is transformed from a static flat structure to a dynamic multi-segment structure that can be bent and folded. The board is divided into multiple segments (first, second, third, and fourth connection circuit boards) that can rotate relative to each other around folding lines, enabling the board to change its spatial configuration and reduce the space it occupies within the electronic device housing.
Solution Approach 2:
The multi-segment connection circuit board is designed to fold and nest within the housing of the electronic device. When bent, the different segments can be positioned in nested or overlapping configurations, allowing the circuit board to occupy minimal space when not in use while maintaining full electrical connectivity between components.
2Volume of moving object
If the connection circuit board is bent to reduce space, then space occupation is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The connection circuit board is divided into multiple discrete segments connected by folding lines. Each segment can be independently manufactured and then assembled, allowing for precise control of the bending angles and positions. This segmentation enables the complex bent shape to be achieved through simpler, more controllable manufacturing steps compared to attempting to bend a single continuous board.
Solution Approach 2:
The folding lines and bending angles are pre-determined and pre-marked on the connection circuit board during the manufacturing process. The segments are pre-assembled in their correct relative positions and orientations before final integration into the device, ensuring that the bending precision requirements are met through careful preliminary setup and alignment rather than requiring extreme precision during final assembly.
