Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing current demand in smaller electronic devices leads to heat generation issues, potentially causing device failure due to elevated temperatures in existing electrical connectors.
Innovation Solution
The electrical connector design features terminals with two connecting portions, allowing for a dual-point connection to the substrate, reducing the electrical path length and overall resistance, thereby minimizing heat generation even under high current flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a single connecting portion is used for terminal connection, then the device structure is simple, but the electrical resistance is high and heat generation occurs under high current flow
Solution Approach 1:
The terminal connecting portion is divided into multiple segments (first connecting portion and second connecting portion) that are electrically connected in parallel. This segmentation reduces the overall electrical resistance by providing multiple current paths, thereby reducing heat generation under high current flow conditions while maintaining a relatively simple overall structure.
2Power
If current demand is increased in smaller electronic devices, then the power capability is improved, but heat generation increases potentially causing device failure
Solution Approach 1:
The terminal structure is segmented into multiple connecting portions that conduct current in parallel. This allows the device to handle higher current demands by distributing the current across multiple paths, thereby increasing power capability while preventing excessive heat generation that would lead to device failure.
Solution Approach 2:
The terminal connecting portions are arranged in a spatial distribution rather than a single linear path. This dimensional arrangement creates multiple parallel current paths through the substrate, effectively increasing the cross-sectional area for current flow and reducing resistive heating while maintaining compact device dimensions.
