Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The increased power consumption and heat generation in servers lead to coolant intrusion into power supply mechanisms, damaging them and necessitating the use of expensive waterproof power supply mechanisms, thereby increasing server manufacturing costs.

Innovation Solution

A power supply mechanism for servers featuring a waterproof housing with specific through holes and a power supply plug design that prevents coolant ingress, eliminating the need for high-cost waterproof components by using a cable and plug configuration that ensures electrical connectivity while maintaining coolant containment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a power supply mechanism with better waterproof performance is used to prevent coolant intrusion, then the reliability of the power supply mechanism is improved, but the manufacturing cost of the server increases

Engineering Contradiction:

Improvewaterproof performanceVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The power supply mechanism is divided into a waterproof housing that forms a separate waterproof cavity, isolating the power supply plug and cable connections from the coolant environment. This segmentation allows the use of standard components within the protected cavity rather than requiring expensive waterproof-rated components throughout the entire system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The waterproof housing acts as an intermediary barrier between the coolant in the accommodating cavity and the power supply components. It prevents direct contact between coolant and electrical components while allowing power transmission through the structured openings, thereby protecting standard components from coolant damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If the power supply mechanism is exposed to coolant for cost reasons, then the manufacturing cost is reduced, but the power supply mechanism is damaged due to coolant intrusion

Engineering Contradiction:

Improvemanufacturing costVSAvoidpower supply functionality

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

Instead of using expensive waterproof-rated power supply components throughout the system, the invention uses a relatively simple waterproof housing structure that can be manufactured at lower cost. This housing protects standard, less expensive power supply components from coolant exposure, achieving reliability without requiring costly waterproof components throughout.
