Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If circular through-holes are used in the electrification plate, then the structure is simple and easy to manufacture, but the air flow area is reduced and air conditioning efficiency decreases
Solution Approach 1:
The electrification plate is divided into multiple rectangular through-holes arranged in a grid pattern, maximizing the total open area while maintaining structural integrity. This segmentation allows more air to pass through simultaneously, improving air conditioning efficiency without complicating the manufacturing process.
2Ease of manufacture
If circular through-holes are used in the electrification plate, then the manufacturing process is simplified, but the flow area of air is reduced and fan load increases
Solution Approach 1:
The plate is segmented into multiple rectangular openings that collectively provide a larger flow area, reducing the resistance to air flow and thereby decreasing the power required by the fan to maintain the necessary air circulation.
3Device complexity
If circular through-holes are used in the electrification plate, then the structure is simple, but foreign matters can block the holes and cause instability
Solution Approach 1:
The electrification plate is segmented into multiple small rectangular holes rather than a few large circular ones. This segmentation reduces the likelihood of complete blockage by foreign matters, as particles are less likely to obstruct multiple small openings simultaneously, thereby improving system reliability and stability.
4Device complexity
If circular through-holes are used in the electrification plate, then the design is simple, but the flow rate of air is reduced and electrification efficiency decreases
Solution Approach 1:
The electrification plate is divided into multiple rectangular through-holes that maximize the total open area, allowing a higher volume of air to pass through the electrification zone per unit time. This increased flow rate directly improves electrification efficiency without significantly increasing device complexity.
