Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional detection methods are used for testing servers in a server cabinet, then measurement functionality is achieved, but the number of plug-connection operations increases, leading to increased time cost and labor cost
Solution Approach 1:
The test jig is divided into multiple isolation sections, each capable of independently testing a server. This segmentation allows parallel testing operations and eliminates the need for repeated plug-connection operations for each server, thereby improving test efficiency and reducing time loss.
Solution Approach 2:
The test jig acts as an intermediary device between the power distribution unit and servers. It provides a centralized testing interface with isolation sections that can simultaneously connect to multiple servers, eliminating the need for technology persons to perform numerous individual plug-connection operations and significantly reducing test time.
2Productivity
If traditional detection methods are used for testing servers in a server cabinet, then measurement functionality is achieved, but complex plug-connection operations are required, leading to increased labor cost
Solution Approach 1:
The test jig incorporates multiple isolation sections that can independently test different servers. This segmentation simplifies operations by allowing technology persons to perform testing through a standardized interface for each section, reducing the complexity of plug-connection operations and lowering labor costs.
Solution Approach 2:
The test jig is designed with universal isolation sections that can test various types of servers using the same interface and methodology. This multi-functionality reduces operation complexity by eliminating the need for different testing procedures for different server types, thereby reducing labor cost and improving efficiency.
3Productivity
If isolation sections are added to the test jig for independent server testing, then test efficiency is improved, but device complexity increases
Solution Approach 1:
The test jig is divided into multiple isolation sections, each with independent testing capabilities. While this segmentation improves test efficiency by enabling parallel testing, it does increase device complexity. The patent accepts this trade-off as the modular design allows for systematic expansion without proportionally increasing operational complexity.
