Solution Overview

Problem

The lack of interchangeability between SSD form factors in datacenters leads to inventory management challenges and discourages system upgrades due to incompatible power consumption and thermal dissipation capabilities, resulting in inefficient SSD utilization and maintenance costs.

Innovation Solution

A unified SSD design with a mechanical actuator that adjusts power consumption based on form factor and thermal changes, using a heatsink or latch mechanism to signal the controller for appropriate power mode, ensuring compatibility and efficient power usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If different form factor SSD products are used to match specific system device slots, then power consumption and heat dissipation requirements are met, but interchangeability between SSDs and slots is lost

Engineering Contradiction:
Improvepower consumption and heat dissipation matchingVSAvoidinterchangeability between SSDs and slots
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a universal slot design that can accommodate multiple SSD form factors (9.5mm and 18mm) through a single slot type. The slot includes a form factor indicator mechanism that automatically detects the inserted SSD's form factor and adjusts power consumption and heat dissipation parameters accordingly, eliminating the need for separate slot types for different form factors while maintaining proper thermal and power management.

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

Solution Approach 2:

The system dynamically changes power consumption and heat dissipation parameters based on the detected form factor of the inserted SSD. The form factor indicator triggers control logic that adjusts electrical and thermal parameters to match the specific requirements of the inserted device, allowing a universal slot to properly support multiple form factors without compromising reliability.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If datacenter maintains inventory of different form factor SSD products, then SSD failures can be quickly replaced, but inventory costs increase

Engineering Contradiction:
Improvequick replacement of failed SSDsVSAvoidinventory costs
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

By implementing universal slots that accept multiple SSD form factors through a single slot design with automatic form factor detection, the datacenter can maintain an inventory of a single universal SSD type rather than maintaining separate inventories for different form factors. This reduces inventory complexity and costs while still enabling quick replacement of failed drives, as any failed SSD can be replaced with a compatible universal form factor drive.

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

3Adaptability or versatility

If new form factor SSD products are installed in legacy systems, then system upgrades are enabled, but compatibility issues arise due to different operating parameters

Engineering Contradiction:
Improvesystem upgrades to newer form factorsVSAvoidcompatibility of operating parameters
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The universal slot design incorporates automatic parameter adjustment based on form factor detection. When a new form factor SSD is inserted, the form factor indicator detects the change and triggers control logic that adjusts power consumption and heat dissipation parameters to match the new device's requirements. This enables seamless system upgrades to newer form factors while maintaining compatibility and reliability of operating parameters through dynamic adaptation.

Inventive Principle:
Principle #35Parameter changes
