Solution Overview

Problem

Conventional backup power supply modules for computing systems require additional space and cabling, making them difficult to scale and integrate efficiently within server chassis due to their non-DIMM form factor, which complicates the provision of reliable backup power to DIMMs during primary power loss.

Innovation Solution

A backup power supply module in a dual in-line memory module (DIMM) form factor that uses standard mechanical and electrical interfaces, eliminating cables and allowing for easy scalability by inserting additional modules in parallel, with features like rechargeable batteries and JEDEC-compliant pins for secure and efficient energy distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional backup power supply modules are used, then backup power functionality is provided, but additional space and cabling are required, making the system difficult to scale

Engineering Contradiction:
Improvebackup power functionalityVSAvoidcabling and space requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the backup power supply module with the DIMM form factor, combining previously separate components (backup power and memory modules) into a single integrated unit. This eliminates the need for separate cabling and reduces chassis space requirements while maintaining backup power functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The backup power supply module is designed to be universal by adopting the standard DIMM form factor, allowing it to use existing memory slots and interfaces in server systems. This multi-functionality enables the same physical interface to serve both memory operations and backup power distribution without requiring dedicated cabling.

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

2Reliability

If conventional backup power supply modules are used, then backup power is provided, but additional chassis space is required, reducing scalability

Engineering Contradiction:
Improvebackup power provisionVSAvoidchassis space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

By merging the backup power supply into the DIMM form factor, the patent utilizes existing memory slot real estate within the chassis. This eliminates the need for separate dedicated space for backup power modules, thereby reducing overall chassis space requirements and improving scalability.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If standard DIMM interfaces are used for backup power, then scalability is improved by parallel insertion, but power distribution robustness must be maintained

Engineering Contradiction:
ImprovescalabilityVSAvoidenergy distribution robustness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the power distribution system into multiple independent DIMM-form-factor modules that can be inserted in parallel. Each module operates independently through standard interfaces, allowing incremental scaling while maintaining robust power distribution through the aggregated capacity of multiple segments.

Inventive Principle:
Principle #1Segmentation
