Solution Overview
Problem
The existing semiconductor devices face complexity in wiring and connection processes due to densely packed conductors and signal lines, leading to increased wiring length and reduced space-saving properties.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conductors and signal lines are densely packed to save space, then space utilization is improved, but wiring complexity and connection difficulty increase
Solution Approach 1:
The patent extends conductors and signal lines in different spatial directions (positive electrode-side conductor and negative electrode-side conductor in one direction, output-side conductor in another direction, driving signal lines in a third direction) to reduce wiring complexity while maintaining compact space utilization
Solution Approach 2:
The patent segments the wiring arrangement by assigning different conductors and signal lines to different directional extensions from the element array, separating their paths to simplify connection processes while achieving dense packing
2Ease of manufacture
If conductors are extended in the same direction to simplify arrangement, then disposition is simplified, but wiring length increases
Solution Approach 1:
The patent uses multi-directional extension of conductors and signal lines from the element array, allowing each conductor type to extend in its optimal direction rather than all extending in one direction, thereby minimizing total wiring length while maintaining arrangement simplicity
3Length of stationary object
If all conductors and signal lines extend in different directions to minimize wiring length, then wiring length is reduced, but disposition complexity increases
Solution Approach 1:
The patent segments the wiring system into distinct groups (positive electrode-side conductor, negative electrode-side conductor, output-side conductor, driving signal lines) with each group extending in a specific direction, making the multi-directional arrangement systematic and manageable rather than chaotic
