Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the working zone and non-working zone are connected through multiple flexible interconnecting zones, then the flexibility and adaptability of the PCB module is improved, but the complexity of the structure increases
Solution Approach 1:
The PCB module is divided into distinct working zones and non-working zones connected through multiple flexible interconnecting zones. This segmentation allows independent optimization of each zone while maintaining overall flexibility, resolving the contradiction between adaptability and structural complexity.
Solution Approach 2:
Flexible circuit board members with flexible interconnecting zones are used to connect working and non-working zones. These flexible elements provide the necessary adaptability while maintaining a relatively simple overall structure, balancing the two competing requirements.
2Productivity
If the working zone is separated from the non-working zone through cutting interconnecting zones, then the processing speed is improved, but the manufacturing precision may be compromised
Solution Approach 1:
The flexible interconnecting zones are designed with predetermined cut lines and features that facilitate precise cutting. By preparing the structure in advance with clear separation features, both high processing speed and manufacturing precision can be achieved simultaneously.
Solution Approach 2:
The flexible circuit board members allow for precise cutting along predetermined lines while maintaining structural integrity. The flexibility enables accurate positioning and cutting without compromising precision, allowing rapid separation of zones.
3Adaptability or versatility
If multiple flexible interconnecting zones are used to connect working and non-working zones, then the adaptability is improved, but the manufacturing time increases
Solution Approach 1:
Multiple flexible interconnecting zones are integrated into a single flexible circuit board member that can be processed together. This merging allows simultaneous manufacturing of all connections, reducing total manufacturing time while maintaining the adaptability provided by multiple zones.
Solution Approach 2:
The flexible interconnecting zones are pre-configured with cutting lines and assembly features during manufacturing. This preliminary preparation enables rapid assembly and processing, reducing the time required to finalize the multi-zone configuration.

AI summary
A rigid-flex printed circuit board module includes a non-working zone and a working zone. The non-working zone defines a receiving space. The working zone is disposed in the receiving space, and is connected to the non-working zone through a plurality of interconnecting zones. The interconnecting zones are flexible regions having greater flexibility than the non-working zone, and are of the same thickness and material. The interconnecting zones are defined by flexible circuit board member such that the interconnecting zones can be quickly cut off using a single machine during processing of the rigid-flex printed circuit board module. Thus, the speed of separating the working zone from the non-working zone can be increased, and costs and time associated with processing and manufacturing can be reduced. Additionally, the processing flow can be simplified, and the product quality of the working zone after cutting can be ensured.
