1Area of stationary object

If conventional multi-server chassis configurations are used, then ease of operation and installation are maintained, but space utilization efficiency deteriorates

Engineering Contradiction:

Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent implements interlocking blade servers where one server unit is nested within the structure of another, allowing dual-height blade servers to interlock vertically. This nesting configuration maximizes space utilization by accommodating servers in a compact arrangement while maintaining standardized installation procedures through automated orientation detection and adapter-based connectivity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The system dynamically adapts to different server orientations using gravity sensors that automatically detect whether a blade server is installed upright or inverted. The BIOS and network ASIC then dynamically adjust pinout configurations accordingly, enabling flexible installation orientations without requiring manual reconfiguration, thus improving space utilization while maintaining ease of operation.

Inventive Principle:
Principle #15Dynamics

2Productivity

If dual-height blade servers are interlocked to increase density, then productivity and space efficiency improve, but device complexity increases due to orientation detection and pinout inversion requirements

Engineering Contradiction:
Improveserver densityVSAvoidsystem configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The blade servers perform self-configuration through automated orientation detection using gravity sensors. When a server is installed, the system automatically detects its orientation (upright or inverted) and configures the appropriate pinout settings without requiring manual intervention. This self-service mechanism increases server density while minimizing the perceived complexity for users.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system changes operational parameters dynamically based on detected orientation. The BIOS and network ASIC modify pinout configurations according to the gravity sensor readings, automatically adapting transmit and receive signal assignments. This parameter change approach enables high server density with dual-height interlocking while managing complexity through automated adaptation rather than fixed complex configurations.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the system automatically inverts pinout based on orientation detection, then adaptability to different installations improves, but device complexity increases due to additional sensors and control logic

Engineering Contradiction:
Improveinstallation orientation flexibilityVSAvoidsensor and control system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gravity sensor and orientation detection system serves multiple functions: it detects installation orientation, triggers appropriate pinout inversion, and enables the system to support both upright and inverted blade server configurations. This multi-functionality approach improves adaptability to different installation orientations while minimizing added complexity by using a single sensor system for multiple purposes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements pinout inversion as a direct response to detected orientation. When a blade server is installed in an inverted orientation, the network ASIC automatically inverts the pinout configuration to maintain proper signal connectivity. This inversion mechanism provides universal adaptability to any installation orientation while keeping the control logic relatively simple through direct sensor-to-inversion mapping.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

A unit of information technology equipment (ITE), such as a compute node or a network switch, comprises a system board in communication with network connectors that selectively connect to a network interconnect, a gravity sensor for detecting a first orientation and a second orientation of the system board, and a basic input/output system (BIOS) in communication with the gravity sensor to receive a signal identifying whether the system board is in the first or second orientation. The ITE further comprises a network ASIC (application specific integrated circuit) that inverts the pinout of transmit and receive signals in the network connectors in response to a command from the BIOS indicating that the system board is in the second orientation. A system may comprise a first ITE in a first orientation that interlocks with a second ITE in a second orientation that is inverted 180 degrees from the first orientation.
