Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supply systems require frequent adjustments and complex wiring for testing purposes, leading to poor signal quality and inefficiencies due to the need for individual unit switching and overcurrent risks.
Innovation Solution
A parallel connected multiple power supply cabinet system with a main programmable power distribution unit that controls ON-OFF operations of each power supply unit, ensuring high-quality signal output by electrically parallel connecting multiple units within a cabinet, with a power distribution unit managing power input and output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual power supply units are used for testing, then flexibility in testing different appliances is achieved, but adjustment time and operational complexity increase significantly
Solution Approach 1:
Multiple power supply units are merged into a single cabinet with shared control features. The cabinet integrates multiple units that can be independently adjusted through a unified control interface, eliminating the need to physically access and adjust each unit separately. This combining approach maintains testing flexibility while dramatically reducing adjustment time.
2Productivity
If multiple power supply units are connected for testing, then testing capacity increases, but wiring complexity increases and signal quality deteriorates
Solution Approach 1:
The cabinet is segmented into multiple independent power supply units, each capable of being individually controlled and adjusted. This segmentation allows multiple units to operate independently within a unified cabinet structure, maintaining simple internal wiring while enabling expanded testing capacity across multiple channels.
3Power
If multiple power supply units are connected in conventional manner, then power output capacity increases, but overcurrent risks and signal quality issues arise
Solution Approach 1:
The control unit implements feedback mechanisms to monitor and regulate the output of each power supply unit. By continuously monitoring current and voltage levels, the system can prevent overcurrent conditions and maintain signal quality. The feedback loop allows real-time adjustments to ensure reliable operation while maximizing power output capacity.
