Solution Overview
Problem
Conventional fan arrays lack individual control of fan units based on their performance, leading to inefficient operation and frequent adjustments, and are difficult to assemble and maintain due to complex wiring and cumbersome design.
Innovation Solution
A fan array system with a master controller that communicates with local motor controllers to set target operating parameters for each fan unit, allowing individual control and simplifying assembly and maintenance through a signal path with outlets for easy connection and quick-disconnect capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fan units are controlled based on overall fan array performance, then centralized control is simplified, but individual fan unit efficiency is reduced and frequent adjustments are required
Solution Approach 1:
The control system is segmented into a master controller that receives feedback from sensors and individual fan units, and local controllers that manage each fan unit's operation independently. This allows centralized coordination while maintaining individual optimization capability for each fan unit based on its specific performance parameters.
2Productivity
If fan units are individually controlled based on their performance, then operational efficiency is improved, but control system complexity increases
Solution Approach 1:
The control system is divided into hierarchical levels: a master controller for overall coordination and individual controllers for each fan unit. Each fan unit has its own controller that independently processes feedback from sensors specific to that unit, enabling individualized performance optimization without requiring complex centralized control logic for each unit.
Solution Approach 2:
Sensors are positioned to detect performance parameters of individual fan units and the overall fan array. This feedback is transmitted to controllers that automatically adjust fan unit operations to maintain optimal efficiency, reducing the need for manual adjustments and frequent interventions.
3Ease of operation
If conventional wiring systems are used to power and control fan units, then remote power distribution is achieved, but assembly and maintenance difficulty increases due to wire clutter
Solution Approach 1:
Power and control signals are merged into integrated wiring systems that are bundled and routed through the fan array frame structure. This consolidation reduces the number of separate wire runs needed, minimizes wire clutter, and simplifies both assembly and maintenance operations while maintaining the ability to distribute power and control signals to multiple fan units.
Solution Approach 2:
The wiring system is designed with universal connectors and routing paths that can serve multiple fan units through a single infrastructure. This multi-functional wiring approach eliminates the need for dedicated separate wiring for each fan unit, reducing overall complexity and improving ease of assembly and maintenance.
4Manufacturing precision
If fan units require substantial assembly time, then manufacturing precision is maintained, but productivity decreases
Solution Approach 1:
Fan units are pre-assembled with integrated controllers and pre-configured wiring connections before being installed in the fan array. This preliminary preparation ensures proper alignment and connection precision while significantly reducing the time required during final assembly, as units can be quickly mounted and connected without extensive on-site wiring and alignment work.
