Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual updates to server management databases are time-consuming and prone to errors, leading to inaccurate information about server positions within racks, especially when servers are moved or added, causing delays in knowing the real status of each server.
Innovation Solution
A server management system that uses two wave generators on the rack and a wave sensor on the server to emit and sense omni-directional and directional waves at different times, determining angles based on time differences to calculate the server's position, with a look-up table to identify the rack and update the database automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual updates to server management database are performed, then the database can be maintained, but it is time-consuming and prone to errors leading to inaccurate information
Solution Approach 1:
The patent replaces the manual mechanical process of database updating with an automated wave-based detection system. Wave generators emit waves that reflect off servers, and wave sensors detect these reflections to automatically calculate server positions, eliminating manual intervention and its associated errors and time consumption.
Solution Approach 2:
The server position tracking system performs self-updating through automated wave emission and detection. The system continuously monitors server positions without external intervention, with the wave generators and sensors working autonomously to maintain accurate position information in the database.
2Loss of time
If manual database updates are delayed, then less time is spent on updates, but the server management interface renders wrong information about server positions
Solution Approach 1:
The wave generators continuously emit waves and wave sensors continuously detect reflections, maintaining constant monitoring of server positions. This continuous automated operation ensures the database is always updated with current position information, eliminating the need for periodic manual updates and preventing information staleness.
Solution Approach 2:
The system uses wave reflections as feedback to continuously verify server positions. When servers move, the changed reflection patterns provide immediate feedback to the detection system, which automatically updates the database, ensuring information accuracy without manual intervention.
3Measurement precision
If wave generators and wave sensors are used to automatically track server positions, then real-time accurate tracking is achieved, but the device complexity increases
Solution Approach 1:
The system divides the tracking function into separate components: wave generators for emission, wave sensors for detection, and a calculation unit for position determination. This segmentation allows each component to be optimized independently and simplifies the overall system architecture while maintaining high measurement precision.
Solution Approach 2:
The patent uses waves as an intermediary medium to transfer information about server positions. Instead of direct mechanical or electronic connections between servers and the management system, waves serve as the mediator that carries position information, simplifying the physical infrastructure while enabling precise measurement.

AI summary
A server management system disposes two wave generators on a rack and disposes a wave sensor on a server, wherein each of the wave generators is capable of emitting an omni-directional wave and a directional wave. When the wave sensor senses the omni-directional wave and the directional wave at different time points, one of the server and a host device is capable of determining two angles of the wave sensor relative to the two wave generators according to time differences and then calculating a position of the server located in the rack according to the two angles.
