Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a flexible substrate is used for the sensor board, then the weight of the radiographic imaging apparatus can be reduced and imaging becomes easier, but reworking becomes difficult due to substrate deflection
Solution Approach 1:
The sensor board is divided into a sensor board proper and a cable board that can be separated. The cables connect to the sensor board through connectors that can be detached, allowing the cable board to be separated for reworking without handling the entire flexible sensor board. This segmentation enables easy replacement of circuit parts while maintaining the lightweight flexible design.
Solution Approach 2:
Connectors are introduced as intermediary components between the cables and the sensor board substrate. These connectors provide a standardized interface that allows cables to be connected and disconnected without directly manipulating the flexible substrate, thus enabling easy reworking while preserving the lightweight flexible sensor board design.
2Device complexity
If cables are directly connected to the flexible substrate, then the structure is simplified, but positional deviation of cables makes reconnection difficult
Solution Approach 1:
Connectors are pre-mounted on both the cables and the sensor board in advance during manufacturing. This preliminary action ensures that connection positions are precisely defined before actual assembly, eliminating positional deviation issues during reconnection. The connectors are positioned at predetermined locations that account for any substrate flexibility, allowing consistent and accurate reconnection.
Solution Approach 2:
Connectors serve as intermediary components that mediate the connection between cables and the flexible substrate. These connectors provide fixed reference positions and alignment features that eliminate positional deviation problems, allowing cables to be reliably reconnected even when the flexible substrate deflects or shifts during handling.
3Adaptability or versatility
If circuit parts are mounted on flexible cables, then adaptability is improved, but manufacturing precision is reduced due to substrate deflection
Solution Approach 1:
The system is segmented into a flexible sensor board portion and a separate cable board portion with connectors. This segmentation allows the sensor board to maintain its flexible, adaptable form factor while the separate cable board can be manufactured and assembled with high precision using rigid fixtures and alignment tools, eliminating the manufacturing precision problems that would arise from working directly on flexible substrates.
Solution Approach 2:
Connectors act as intermediary components that bridge the flexible sensor board and the rigid cable board. These connectors provide precise mechanical and electrical interfaces that can be manufactured with high accuracy, compensating for the flexibility of the sensor board. The connectors ensure consistent positioning and connection quality regardless of substrate deflection during assembly or reworking.
