Pivoting Frame for Electronic Card Access in Aircraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and maintenance of electronic cards in restricted spaces, such as those found in aircraft, boats, and land vehicles, are hindered by the bulk of fixed frames and the difficulty of accessing and replacing cards through small openings.
Innovation Solution
An electrical equipment design featuring a fixed frame with a pivoting frame that allows for a storage compartment with a front opening, enabling the pivoting frame to switch between a storage position within the compartment and an accessibility position, facilitating the introduction and removal of electronic cards through a front opening, while providing electrical connections and ventilation passages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic cards are mounted in fixed frames with parallel arrangement, then electrical connection and card mounting are achieved, but access and replacement of cards become difficult in restricted spaces
Solution Approach 1:
The frame is designed to pivot between a storage position (cards accessible from the front) and an accessibility position (cards accessible from the rear), transforming a static structure into a dynamic one that adapts to maintenance needs
Solution Approach 2:
The frame is divided into multiple card slots that can be independently accessed, with each slot containing electrical connection means that can be selectively engaged or disengaged
2Stability of the object's composition
If fixed frames are used for mounting electronic cards, then stable mounting is achieved, but the bulk of the frame creates space constraints in confined installations
Solution Approach 1:
The pivoting mechanism allows the frame to collapse into a compact configuration when not in use, reducing its volume while maintaining structural integrity and card stability during operation
Solution Approach 2:
The frame can be folded or nested into a more compact form factor, with card slots and connection means designed to nest together when the frame is in its closed or transport position
3Ease of repair
If cards are individually removable and replaceable by sliding, then card replacement is simplified, but electrical connection reliability may be compromised
Solution Approach 1:
The electrical connection means are designed to dynamically engage and disengage as the frame pivots, ensuring reliable electrical contact during normal operation while allowing easy card removal when needed
Solution Approach 2:
The pivoting frame itself acts as an intermediary mechanism that mediates between the card and the fixed mounting structure, providing both stable electrical connection and ease of replacement through its controlled movement

AI summary
Electrical equipment, in particular for aircraft, comprising: a fixed frame delimiting a storage compartment having a front opening, a pivoting frame mounted to pivot on the fixed frame to occupy a storage position in which it is placed inside the storage compartment of the fixed frame and an accessibility position in which it extends through the front opening of the fixed frame, the pivoting frame delimiting a reception space having at least one access opening, situated behind its front, for the introduction of electronic cards and their removal when the pivoting frame is in said accessibility position in which said access opening is situated in front of said front opening of the fixed frame, the pivoting frame being provided with electrical connection means that can be coupled to electrical connection means of the electronic cards.
