Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional water-cooling unit latch devices face limitations in arranging water pipelines due to interference with the latch device substrate, leading to structural weakness and high manufacturing costs, as they are designed for air-cooling systems and cannot securely lock water blocks without welding, restricting pipeline direction and flexibility.

Innovation Solution

A knockdown water-cooling unit latch device structure composed of multiple latch members assembled around a water-cooling unit via connection members, such as screws or engagement joints, allowing secure connection without interference and enabling flexible pipeline arrangement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single latch device substrate is used to secure the water block, then the water block can be locked, but the water incoming tube and water outgoing tube interfere with the latch device substrate, preventing proper connection

Engineering Contradiction:

Improvelocking reliabilityVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The latch device substrate is divided into multiple separate latch members (first latch member and second latch member). Each latch member independently secures one end of the water block without interfering with the water tubes, thereby resolving the interference problem while maintaining locking reliability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The water tubes are extracted or separated from the interference zone by using multiple distributed latch members that connect to different locations on the water block, allowing the tubes to pass through or around the water block without conflicting with the latching mechanism

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If recesses are formed on the latch device substrate to avoid tube interference, then the tubes can pass through, but the structural strength of the latch device substrate is reduced

Engineering Contradiction:

Improveassembly easeVSAvoidstructural strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

Instead of forming recesses in a single substrate, the latching function is segmented into multiple solid latch members that connect to the water block at different locations, avoiding the need to weaken any single component with recesses

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If different molds are manufactured for latch device substrates with different recess angles, then interference can be avoided for different tube directions, but the manufacturing cost increases significantly

Engineering Contradiction:

Improveadaptability to different tube directionsVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The multiple latch members are designed with identical or similar structures that can be manufactured using the same mold. Each latch member performs the same latching function at different locations, providing universality and eliminating the need for multiple specialized molds, thereby reducing manufacturing costs while adapting to different tube directions

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The latch members are positioned at different locations on the water block, with each member adapted to its specific local geometry and tube arrangement, while maintaining overall structural consistency that allows for standardized manufacturing

Inventive Principle:

Principle #3Local quality

4Reliability

If water tubes are welded to the water block to avoid leakage, then leakage is prevented, but the tubes cannot be rotated to change direction to solve interference problems

Engineering Contradiction:

Improveleakage preventionVSAvoidpipeline direction flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The latching function is segmented into multiple independent latch members that can be positioned at different orientations, allowing the water tubes to maintain their welded connections for leakage prevention while the distributed latch members adapt to different tube directions without requiring tube rotation

Inventive Principle:

Principle #1Segmentation

AI summary

A knockdown water-cooling unit latch device structure includes a latch device assembly having multiple latch members. The latch members are correspondingly assembled with each other around a water-cooling unit. The latch members are connected with each other via at least one connection member. Alternatively, the latch members are directly assembled with each other by means of engagement or lap joint. The latch members of the latch device assembly are assembled with the water-cooling unit so that when the latch device assembly is assembled with the water-cooling unit, the latch members will not interfere with the water-cooling unit.
