Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Orthogonal electrical connector systems often limit airflow due to the adjacency of power and signal connectors, which restricts heat dissipation capabilities in electronic devices.
Innovation Solution
The design includes an electrical connector system with signal and power connectors arranged in an orthogonal configuration on separate surfaces of printed circuit boards, creating empty spaces for airflow and preventing direct contact between signal and power connectors, allowing for improved heat dissipation.

Engineering Contradiction Analysis
1Area of stationary object
If power connectors and signal connectors are arranged adjacent to each other in orthogonal configuration, then space utilization is improved, but airflow is limited and heat dissipation capability deteriorates
Solution Approach 1:
The connector system is segmented into separate signal connector assemblies and power connector assemblies, with signal connectors mounted on one surface of the PCB and power connectors mounted on the opposite surface. This segmentation creates spatial separation that enables airflow channels while maintaining compact overall structure, thus resolving the contradiction between space utilization and heat dissipation.
Solution Approach 2:
The invention transitions from planar adjacent arrangement to three-dimensional orthogonal arrangement by mounting signal and power connectors on opposite surfaces of the PCB. This dimensional change creates vertical separation and enables airflow paths through the connector assembly, improving heat dissipation while maintaining compact footprint.
2Reliability
If power connectors and signal connectors are placed directly adjacent, then device compactness is improved, but heat management capability deteriorates
Solution Approach 1:
The connector system segments high-power and low-power components into separate assemblies mounted on opposite PCB surfaces. This segmentation isolates heat-generating power connectors from sensitive signal connectors, reducing thermal interference while maintaining compact device form factor.
Solution Approach 2:
The PCB itself acts as an intermediary barrier between power and signal connectors, with the board thickness providing thermal isolation. Additionally, airflow channels serve as intermediaries that actively remove heat from power connectors, preventing heat transfer to signal connectors and surrounding components.
