Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature sensing methods for servers in non-standard environments, such as schools, small businesses, and industrial settings, lead to increased manufacturing and labor costs due to the need for separate temperature sensor boards and complex signal testing, resulting in poor heat dissipation and potential server crashes from dust accumulation.
Innovation Solution
A temperature sensing device integrated into the server's mainboard, utilizing a temperature-sensitive triode connected through cables to an external temperature-sensing channel, which converts temperature data into binary format, eliminating the need for separate sensor boards and reducing labor costs by simplifying signal testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate temperature sensor board is placed at the inlet of the server, then temperature sensing function is achieved, but manufacturing costs and labor costs increase
Solution Approach 1:
The patent merges the temperature sensing function with the existing sensor board by integrating a temperature-sensitive element and its signal processing circuitry directly onto the sensor board that is already connected to the mainboard. This eliminates the need for a completely separate temperature sensor board while maintaining the temperature sensing capability, thereby reducing manufacturing complexity and costs.
Solution Approach 2:
The sensor board is designed to serve multiple functions: it acts as both a general sensor interface board and a dedicated temperature sensing board. By making the sensor board multi-functional, the patent eliminates the need for additional dedicated temperature sensing hardware, reducing overall system complexity and manufacturing costs.
2Reliability
If a separate temperature sensor board is used, then temperature data can be obtained, but signal testing requires technician intervention increasing labor costs
Solution Approach 1:
The temperature-sensitive element automatically converts temperature signals into voltage signals that are directly compatible with the mainboard's ADC interface. The signal processing is handled self-service style by the integrated circuitry on the sensor board, eliminating the need for manual signal testing and calibration by technicians.
Solution Approach 2:
The patent replaces manual signal testing procedures with automated electronic signal conversion. The temperature-sensitive element's automatic voltage signal generation substitutes for manual testing mechanisms, allowing the system to self-verify and self-calibrate without technician intervention.
3Temperature
If dust accumulates at the inlet of the server chassis, then heat dissipation efficiency decreases, but adding temperature sensing doesn't prevent dust accumulation
Solution Approach 1:
The patent implements a feedback mechanism where the temperature sensor continuously monitors the temperature at the server inlet and reports to the mainboard. The mainboard can then use this feedback information to trigger alerts, adjust system operations, or notify maintenance personnel when temperature rises indicate dust accumulation is affecting heat dissipation.
