Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If series power supply is adopted for hash chip groups, then power supply structure is simple, but interlayer voltage becomes unbalanced due to different internal resistance of hash chips
Solution Approach 1:
The patent applies preliminary action by pre-cooling the hash board to a preset temperature before startup, and by pre-adjusting the refrigerating device runtime based on ambient temperature. This preliminary preparation reduces temperature-induced resistance variations before power is applied, thereby establishing voltage balance across hash chip groups before operation begins, without requiring complex power supply circuitry
2Loss of time
If hash chips are turned on simultaneously, then startup process is fast, but leakage current differences cause voltage imbalance and affect signal transmission
Solution Approach 1:
The patent applies segmentation by dividing the startup process into distinct phases: pre-cooling phase, gradual startup phase where hash chip groups are activated sequentially rather than simultaneously, and stabilization phase. This segmented approach allows each hash chip group to initialize properly with controlled leakage current, preventing voltage imbalance while maintaining reasonable startup speed
Solution Approach 2:
The patent implements periodic action through the refrigerating device that operates in cyclic intervals - running before startup to pre-cool, then periodically adjusting its operation during and after startup based on temperature monitoring. This periodic refrigeration maintains optimal temperature conditions throughout the startup sequence, ensuring stable leakage current characteristics
3Duration of action of moving object
If chip temperature is high before power-on, then device can start quickly without pre-cooling, but leakage current increases and causes voltage imbalance
Solution Approach 1:
The patent applies preliminary action by implementing a pre-cooling routine before hash board startup. The control device checks ambient temperature and, if above a preset threshold, activates the refrigerating device for a calculated duration to pre-cool the hash board. This preliminary temperature reduction minimizes leakage current at startup, establishing voltage balance without significantly extending total startup time
Solution Approach 2:
The patent implements feedback through temperature monitoring during the pre-cooling phase. The control device continuously monitors hash board temperature and adjusts refrigerating device runtime based on actual temperature readings versus target temperature. This feedback mechanism optimizes the balance between pre-cooling duration and energy consumption, reducing leakage current effectively while minimizing unnecessary refrigeration cycles
