Floor Cable Routing Layout for Airflow-Aware Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The locations of cables wired in a floor are not clear due to unmanaged cable routes, and the total sum of cable cross-sectional areas is unknown, leading to potential biases in cable placement that can block cold air flow and deteriorate air-conditioning efficiency.
Innovation Solution
The method involves setting unit areas in the floor where cables are to be wired, specifying cable routes within these areas, managing cable cross-sectional areas through a database, and selecting optimal routes to avoid cable biases. Additionally, CFD analysis is performed by approximating cables as rectangular parallelepipeds to reduce calculation complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If cable routes are not managed, then cable material costs are reduced by short routing, but cable locations become unclear and air-conditioning efficiency deteriorates
Solution Approach 1:
The floor space is divided into multiple unit areas, and cable routes are managed by specifying which unit areas cables pass through. This segmentation allows clear tracking of cable locations while maintaining flexible routing for cost efficiency.
2Adaptability or versatility
If cable routes are not managed, then wiring flexibility is maintained, but cable density distribution becomes uncontrolled causing air flow blockage
Solution Approach 1:
The system manages cable density at the local level of each unit area by tracking which cables pass through which unit areas. This allows control of cable distribution in specific locations to prevent air flow blockage while maintaining overall wiring flexibility.
Solution Approach 2:
The system calculates and determines optimal cable routes in advance by evaluating the number of cables passing through each unit area before actual cable installation. This preliminary planning prevents excessive cable concentration that would block air flow.
3Measurement precision
If CFD analysis is performed with detailed cable definitions, then air-conditioning efficiency evaluation precision is improved, but calculation complexity becomes huge
Solution Approach 1:
Instead of performing CFD analysis with detailed individual cable definitions, the system creates a simplified copy or model by calculating the number of cables passing through each unit area. This reduced model maintains sufficient precision for air-conditioning efficiency evaluation while dramatically reducing calculation complexity.
