Integrated DC Output Harness Layout for Compact PC Power Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional power supply lines in host computers are heavy, costly, and poorly managed, leading to inefficient use of space and obstructed airflow due to disorganized electrical wires, which negatively impacts the extension efficiency and cooling of the computer.
Innovation Solution
An integrated power supply DC output line featuring wires arranged in a polar array on a radial cross-section, with a sheathed wire at the center and unsheathed wires positioned equiangularly around it, reducing wire wind resistance and allowing for a more compact and organized cable management system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional power supply lines with multiple separate wire harnesses are used, then power can be supplied to multiple components, but the wire harnesses occupy much space and obstruct airflow inside the host computer
Solution Approach 1:
The patent combines multiple separate wire harnesses (motherboard power harness, CPU power harness, PCI power harness, hard drive power harness) into a single integrated power supply DC output line. This integration maintains the ability to supply power to multiple components while significantly reducing the total space occupied by cable management, directly resolving the contradiction between power supply capability and space occupation.
2Reliability
If traditional power supply lines with disorganized electrical wires are used, then power can be distributed to various components, but airflow is obstructed and air cooling efficiency is reduced
Solution Approach 1:
By merging multiple wire harnesses into a single integrated cable assembly with organized internal wiring, the patent eliminates the disorganized wire layout that obstructs airflow. The integrated design allows for streamlined cable routing that maintains power distribution functionality while improving air flow paths for cooling components.
3Adaptability or versatility
If multiple separate wire harnesses are used for different components, then each component can be powered independently, but cable management becomes complex and space efficiency is reduced
Solution Approach 1:
The patent integrates multiple wire harnesses into a single cable assembly with a unified connector system that can independently power multiple components. This merging approach simplifies cable management by reducing the number of separate harnesses to organize and install, while maintaining the adaptability to connect to different components through the integrated design.
4Power
If traditional heavy power supply lines are used, then sufficient power can be delivered to components, but material cost increases and production efficiency decreases
Solution Approach 1:
By combining multiple wire harnesses into a single integrated power supply DC output line, the patent reduces the total amount of materials required (fewer insulation layers, fewer protective coatings, less wire stock) while maintaining adequate power delivery capability. This integration streamlines the manufacturing process and reduces production complexity, directly improving productivity.
