Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the width of the circuit board is reduced to increase battery capacity, then the battery capacity increases, but the wiring area becomes too narrow to accommodate MIPI signal lines with minimum width requirements
Solution Approach 1:
The patent introduces a connection circuit board that extends in the width direction beyond the circuit board body, utilizing additional spatial dimension to route connection wires. This allows the wiring area to expand laterally rather than being constrained within the narrow circuit board width, thereby accommodating sufficient wiring area while maintaining reduced circuit board width for increased battery capacity.
Solution Approach 2:
The connection circuit board serves as an intermediary component between the circuit board body and external connections. It carries connection wires that bridge the gap created by the narrow wiring area on the circuit board body, enabling MIPI signal lines and other connections to be established without requiring increased width on the main circuit board.
2Volume of moving object
If the wiring area is narrowed to accommodate battery size, then the device becomes more compact, but the signal lines cannot be connected reliably due to insufficient width
Solution Approach 1:
The connection circuit board extends laterally beyond the circuit board body boundaries, utilizing the width dimension to provide adequate wiring area. This dimensional extension ensures that connection wires have sufficient width for reliable signal transmission while the overall device maintains compact form factor through optimized vertical stacking and space utilization.
Solution Approach 2:
The patent divides the circuit board system into two functional segments: the circuit board body for mounting components and the connection circuit board for signal routing. This segmentation allows the connection circuit board to be optimized specifically for wiring requirements with adequate width, while the circuit board body maintains compact dimensions for device integration.
3Adaptability or versatility
If a hole is formed in the circuit board to accommodate the fingerprint module, then the fingerprint module can be integrated, but the wiring areas on both sides of the hole become too narrow for signal line connections
Solution Approach 1:
The connection circuit board acts as an intermediary that routes connection wires around the fingerprint module accommodation hole. By extending laterally beyond the circuit board body, it provides alternative pathways for signal lines that would otherwise be blocked or constrained by the hole, ensuring adequate wiring width for reliable connections on both sides of the hole.
Solution Approach 2:
The connection circuit board utilizes the lateral width dimension to bypass the spatial obstruction created by the fingerprint module hole. Connection wires are routed through this extended dimension, allowing them to connect components on opposite sides of the hole without passing through the narrow wiring areas immediately adjacent to the hole opening.
