Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional routing structures with orthogonal tracks on substrates limit the flexibility of conductive trace routing, leading to increased distance between electronic components and potential routing congestion, which can result in higher parasitic capacitance and hindered signal transmission.
Innovation Solution
The routing structure employs inclined conductive tracks with respect to the substrate boundary, allowing for more flexible routing directions and shorter trace lengths, thereby reducing parasitic capacitance and enhancing signal transmission.

Engineering Contradiction Analysis
1Ease of manufacture
If orthogonal tracks are used on substrates, then routing structure is simple and easy to manufacture, but the distance between electronic components increases and routing congestion occurs
Solution Approach 1:
The patent applies asymmetry by transitioning from orthogonal (symmetric 90-degree) track layouts to inclined track layouts with varying angles. The conductive traces are routed at non-orthogonal angles relative to the substrate boundaries, allowing optimization of trace lengths and routing paths while maintaining manufacturing feasibility through controlled angle variations.
Solution Approach 2:
The patent changes the routing parameter from fixed orthogonal angles to variable inclined angles. By adjusting the track angles to optimal values rather than being constrained to 90 degrees, the design achieves shorter trace lengths and reduced routing congestion while still being manufacturable with standard PCB routing techniques.
2Device complexity
If orthogonal tracks are used on substrates, then routing structure is simple, but parasitic capacitance increases and signal transmission is hindered
Solution Approach 1:
The patent uses asymmetric inclined track angles to optimize signal transmission paths. By routing traces at angles other than orthogonal, the design reduces parasitic capacitance effects and improves signal integrity while maintaining reasonable structural complexity through systematic angle selection.
Solution Approach 2:
The patent modifies the routing angle parameter from fixed orthogonal to variable inclined angles to optimize electrical performance. This parameter change reduces parasitic capacitance and improves signal transmission quality while keeping the overall routing structure manageable through controlled angular variations.
3Ease of manufacture
If orthogonal tracks are used on substrates, then manufacturing is easier, but routing flexibility is limited
Solution Approach 1:
The patent employs asymmetric inclined track configurations to enhance routing flexibility. By allowing tracks to be routed at various angles rather than being restricted to orthogonal directions, the design achieves greater adaptability for connecting electronic components while remaining compatible with standard manufacturing processes.
Solution Approach 2:
The patent changes the routing angle parameter from fixed orthogonal to variable inclined angles, providing increased routing flexibility. This allows traces to be optimized for specific component layouts and electrical requirements while still being manufacturable using conventional PCB routing techniques with controlled angle specifications.
