Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an integrated electrical fuse is implemented in the plug contact to protect against overcurrents and overvoltages, then the protection level of computing servers is improved, but the device complexity increases
Solution Approach 1:
The patent combines the fuse function directly into the plug contact structure, merging the protection function with the connection function. This integration reduces the need for separate protection devices while maintaining comprehensive protection against overcurrents and overvoltages, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The plug contact is designed to automatically detect and respond to fault conditions through the integrated fuse, which self-actuates to disconnect the circuit when excessive current or voltage is detected. This self-service mechanism eliminates the need for external protection circuits or manual intervention, improving protection while keeping the system relatively simple.
2Ease of repair
If a multi-part plug contact design with separate cable connection area and plug-in area is used, then the ease of maintenance and quick replacement is improved, but the device complexity increases
Solution Approach 1:
The plug contact is divided into distinct functional areas: a cable connection area for secure cable attachment and a plug-in area for connection to the computing server. This segmentation allows the cable connection area to be replaced or serviced independently without affecting the plug-in area, significantly improving ease of maintenance and quick replacement while keeping each segment relatively simple in design.
3Reliability
If the electrical connection between plug-in area and cable connection area can be separated in the event of a fault, then the protection of computing servers is improved, but the loss of time for fault isolation increases
Solution Approach 1:
The patent extracts the fault isolation capability into a separate, easily activated mechanism that physically disconnects the plug-in area from the cable connection area upon fault detection. This extracted isolation function allows the faulty section to be quickly separated from the healthy sections, minimizing downtime while maintaining protection. The separation mechanism is designed to be rapidly deployable, reducing the time penalty associated with fault isolation.

AI summary
Disclosed is a transmission device which protects at least one computing server connected to it from excessive electrical currents and/or overvoltages. The transmission device has a plug contact, the plug-in area of which can be electrically separated from the cable connection area in the event of a fault, for example by an electrical fuse. In order to minimize the downtime of the respective computing server in the event of a fault, the transmission device is replaced by a back-up transmission device, and the transmission device can be restored and kept as a new back-up transmission device for a further possible fault.'
