Hot swappable pump device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Misalignment between the slot of a housing and the quick plug of a hot swappable pump module due to dimensional tolerances prevents the smooth insertion of the outer cover into the slot, causing installation issues in water cooling systems.
Innovation Solution
A hot swappable pump device with an outer cover, pump support, and positioning members that allow for adjustable positioning relative to the pump, enabling alignment adjustments to facilitate smooth insertion despite misalignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dimensional tolerances are maintained within standard limits, then manufacturing cost is controlled, but misalignment between the slot and quick plug occurs preventing smooth insertion
Solution Approach 1:
The pump support is designed as a movable component that can shift position relative to the outer cover. When the pump module is inserted into the housing slot, the pump support automatically adjusts its position to accommodate dimensional tolerances and ensure proper alignment between the quick plug and slot, enabling smooth insertion without requiring high manufacturing precision
Solution Approach 2:
The pump support acts as an intermediary component between the outer cover and the pump. It absorbs the misalignment caused by dimensional tolerances through its movable design, mediating the connection between the outer cover and pump while ensuring proper alignment for smooth insertion into the housing slot
2Ease of repair
If the pump is designed as hot swappable for easy maintenance, then ease of repair is improved, but alignment stability deteriorates causing insertion failures
Solution Approach 1:
The movable pump support provides dynamic alignment compensation that maintains alignment stability during the hot swappable insertion and removal process. The pump support can shift position to accommodate tolerances during insertion while maintaining stable alignment when the pump is properly installed, enabling both easy maintenance and alignment stability
3Strength
If the outer cover is made rigid for structural strength, then strength is improved, but adaptability to misalignment deteriorates
Solution Approach 1:
The system uses a rigid outer cover for structural strength while incorporating a movable pump support that provides the necessary adaptability. The pump support acts as a flexible element within the rigid structure, allowing position adjustment to accommodate misalignment while the outer cover maintains its strength
Solution Approach 2:
The device is segmented into rigid components (outer cover, housing) and a flexible component (movable pump support). This segmentation allows the rigid parts to provide structural strength while the movable pump support provides adaptability to alignment variations
