Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heat dissipation control is based on detecting current temperature at target position, then the control system is simple to implement, but heat dissipation lags behind and components operate at high temperature for long time
Solution Approach 1:
The patent applies preliminary action by calculating heat generation speed based on power consumption values before temperature actually rises. The control system predicts heat accumulation trends and adjusts fan speed in advance, rather than waiting for temperature detection. This proactive approach prevents high-temperature operation before it occurs, resolving the contradiction between simple control implementation and component reliability.
2Temperature
If fan rotating speed is increased to improve heat dissipation speed, then temperature control improves, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by making fan speed adjustable and dynamic rather than fixed. The control system continuously calculates heat generation speed and adjusts fan rotating speed accordingly - increasing speed only when heat generation exceeds dissipation capacity, and reducing speed when heat dissipation is sufficient. This dynamic adjustment optimizes temperature control while minimizing unnecessary energy consumption.
Solution Approach 2:
The patent changes the operating parameters of the fan based on real-time heat generation conditions. By monitoring power consumption values and calculating heat generation speed, the system adjusts fan speed parameters dynamically to match actual thermal conditions, achieving optimal temperature control with minimal energy expenditure.
3Device complexity
If heat dissipation control waits for temperature to reach certain value, then control logic is simple, but heat dissipation effectiveness is reduced
Solution Approach 1:
The patent applies the skipping principle by bypassing the traditional temperature-threshold waiting approach. Instead of waiting for temperature to reach a certain value before acting, the system calculates heat generation speed from power consumption and takes immediate corrective action. This rushes through the delay period, maintaining heat dissipation effectiveness while keeping control logic relatively simple through straightforward calculations.
