Bidirectional Electronic Unit Module Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aeronautical computing units lack modularity in their design, as they are typically configured for module insertion in a single direction, which limits flexibility and space optimization.
Innovation Solution
The design of an electronic unit with a compartment that allows module insertion in two opposite directions, featuring a connection face parallel to the insertion direction, with power supply pads and friction-reducing coatings, and using magnetic or optical couplers for secure connection, enabling orientation-independent installation and symmetric placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the compartment is designed for single-direction module insertion, then the connection structure is simple, but the modularity and installation flexibility are limited
Solution Approach 1:
The connection face is designed with symmetric conductive pads and connection means that can accommodate module insertion from either direction. The power supply pads are arranged symmetrically with respect to the center line, allowing the same connection interface to function regardless of insertion direction, thereby achieving multi-functionality and installation flexibility without proportionally increasing complexity.
Solution Approach 2:
The connection face includes asymmetric elements such as the asymmetric arrangement of conductive pads relative to the module orientation, and the use of asymmetric friction-reducing coatings on specific surfaces. This asymmetric design ensures proper electrical connection and mechanical guidance while allowing bidirectional insertion capability.
2Volume of stationary object
If the module can be inserted in two opposite directions, then the space utilization and modularity improve, but the power supply polarity management becomes complex
Solution Approach 1:
The power supply pads are arranged symmetrically on the connection face such that when a module is inserted from either direction, the electrical contacts are automatically reversed. This symmetric inversion arrangement ensures that the positive and negative power supply connections are correctly oriented regardless of which end of the module is inserted first, eliminating the need for complex polarity detection or switching mechanisms.
3Reliability
If the connection face has high friction, then the module is securely held, but the insertion and removal difficulty increases
Solution Approach 1:
The connection face features localized friction-reducing coatings applied to specific areas where the module makes contact during insertion and removal. These coatings reduce friction only in the insertion path areas, while other areas of the connection face maintain higher friction to ensure secure holding of the module in its installed position, thus achieving both easy insertion and reliable retention.
