Modular Housing Door Cover with Axial Pin Spring Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial computer host housings lack effective ventilation and expansion capabilities, leading to uncontrolled air entry when power supply devices are not in use, and require additional equipment for accommodating multiple power supplies.
Innovation Solution
A modularized housing assembly with multiple accommodating chambers and a door cover system that provides flexible ventilation and isolation, utilizing axial pins, springs, and ventilation openings to manage air flow and pressure, allowing for efficient cooling and expansion without external air intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the accommodating chamber is left open without a door cover, then access to the chamber is easy, but external air enters the housing and disrupts internal air flow patterns
Solution Approach 1:
The door cover is designed as a flexible component that can rotate between a closed position (blocking the opening) and an open position (allowing access). This flexible barrier prevents external air from entering and disrupting internal airflow patterns when closed, while still permitting easy access when opened.
Solution Approach 2:
The door cover is made dynamic through its rotational capability, allowing it to transition between closed and open states. This dynamic design enables the system to adapt between two functional requirements: preventing harmful air entry during operation and allowing easy access when needed.
2Device complexity
If only one accommodating chamber is provided in the housing, then the housing structure remains simple, but the system cannot accommodate multiple power supply devices for expansion
Solution Approach 1:
The housing is segmented into multiple independent accommodating chambers (first, second, and third chambers), each capable of housing a power supply device. This segmentation allows the system to expand from one to multiple power supply devices while maintaining a relatively simple modular structure.
Solution Approach 2:
Each accommodating chamber is designed with universal characteristics, allowing any chamber to serve as a power supply housing. This multi-functional design enables flexible configuration where multiple identical chambers can accommodate different power supply devices, enhancing system versatility without requiring complex specialized structures.
3Object-affected harmful factors
If the door cover is made fixed to close the opening, then external air entry is prevented, but ventilation when power supply device is installed is insufficient
Solution Approach 1:
The door cover is designed as a dynamic component that can rotate between closed and open positions. When a power supply device is installed, the door cover can be opened to allow ventilation and heat dissipation. When no device is installed, it closes to prevent external air from disrupting internal airflow patterns.
Solution Approach 2:
The door cover is positioned and configured in advance to accommodate the power supply device. The design anticipates the need for both closure (to prevent harmful air entry) and opening (for ventilation), and the rotational mechanism is pre-configured to enable this transition based on operational requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modularized housing assembly ensures satisfactory ventilation when power supply devices are inserted, creates negative pressure for effective cooling, and prevents external air entry when devices are not in use, maintaining internal air flow and reducing the need for additional equipment.
Implementation Method 1
a spring (25) accommodated in the axial pin (13), and having one end (251) thereof pushed against the wall surface (121) and the other end (252) thereof pushed against an inner wall surface of the door cover (20)
Implementation Method 2
external air in large amounts are prevented from entering into the idle accommodating chamber, thereby forming negative pressure at the interior of the modularized housing

AI summary
An assembly of modularized housing and door cover includes a modularized housing; a door cover having a upper part thereof formed with at least one sleeve for putting around the axial pin, and a main body thereof formed with a plurality of ventilation openings; a film having a surface thereof partially adhered to peripheral areas of the ventilation openings using an adhesive layer to form loose-leaf connection; and spring accommodated in the axial pin, and having one end thereof pushed against the wall surface and the other end thereof pushed against an inner wall of the door cover. The modularized housing is provided with excellent ventilation effects therein when assembled with power supply device. The accommodating chambers are not assembled with power supply devices, external air in large amounts is prevented from entering into the idle accommodating chamber, thereby forming negative pressure at the interior of the modularized housing.
