Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the memory system operates at high performance, then the operation speed and data processing capability are improved, but the internal temperature increases excessively causing malfunction and damage
Solution Approach 1:
The patent divides the temperature monitoring function into multiple independent temperature sensors placed at different locations within the memory system. This segmentation allows for localized temperature detection and targeted thermal management, enabling the system to maintain high performance while preventing excessive temperature rise in specific regions through selective performance adjustment.
Solution Approach 2:
The patent dynamically changes the operation performance parameter of the memory system based on detected temperature conditions. By adjusting performance parameters (such as operation speed or power consumption) in response to temperature measurements, the system can operate at high performance when temperatures are acceptable and reduce performance to prevent overheating, thus resolving the contradiction between productivity and temperature.
2Measurement precision
If temperature sensors are placed adjacent to the non-volatile memory device, then temperature detection accuracy is improved, but the system cannot distinguish between internal device temperature and external environmental temperature
Solution Approach 1:
The patent places multiple temperature sensors at different locations - some adjacent to the non-volatile memory device and others at different positions within the system. This spatial segmentation allows the system to compare temperature readings from different locations and determine whether the measured temperature originates from internal device operation or external environmental conditions, thereby maintaining both measurement precision and adaptability.
Solution Approach 2:
The patent uses temperature sensors positioned at different locations as intermediaries to infer the source of heating. By comparing temperature gradients and patterns across multiple sensor locations, the system can determine whether heat originates from the non-volatile memory device itself or from external environmental factors, enabling appropriate thermal management decisions.
