Pivotally Mounted Electronic Card for Medical Ventilator Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly, wiring, and maintenance of electronic cards in medical ventilators are complicated due to fixed mounting, which increases the risk of component damage and makes it difficult to ensure correct connections, especially when the card is vertically or tilted during screwing.
Innovation Solution
A medical ventilator design featuring a pivotally mounted electronic card on a support structure within the external casing, allowing the card to be rotated for easier access and handling, with a display screen on a support arm and holding means like screws to secure it in place, facilitating assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic card is fixedly mounted flat in the fan, then the electronic card is securely held in place, but the assembly, wiring and maintenance become complicated and the risk of component damage increases
Solution Approach 1:
The electronic card is mounted on a pivotable support structure that allows it to rotate between a first position for assembly/maintenance and a second position for operation. This dynamic mounting enables the card to be easily accessed and removed when needed, while remaining securely held during operation, thus resolving the contradiction between security and ease of operation.
Solution Approach 2:
The support structure is divided into a pivotable portion that carries the electronic card and a fixed portion attached to the fan housing. This segmentation allows the electronic card to be independently positioned and removed without affecting the entire fan assembly, facilitating easier maintenance while maintaining operational security.
2Stability of the object's composition
If the electronic card is fixedly mounted, then the card remains stable during operation, but the wiring process becomes difficult due to cable tension preventing proper inspection
Solution Approach 1:
The pivotable support structure allows the electronic card to be rotated to an optimal position during wiring operations, enabling operators to access and inspect connection headers on both sides of the card without cable tension interference. Once wired, the card can be secured in its operational position, thus resolving the contradiction between stability and ease of wiring.
3Volume of moving object
If the electronic card is mounted vertically or tilted, then space is optimized in the fan housing, but the risk of component damage increases during screwing operations
Solution Approach 1:
The pivotable support structure allows the electronic card to be positioned at an optimal angle for screwing operations (horizontal or near-horizontal) during assembly, minimizing the risk of component damage. The card can then be rotated to the required vertical or tilted position for space optimization during operation, thus resolving the contradiction between space utilization and component safety.
