Removable Mounting Frames for Flexible Plug-in Unit Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plug-in unit-mounting structures for electronic apparatuses face challenges in efficiently mounting plug-in units of different sizes and thicknesses, as the guide rails are often fixed to the shelves, limiting flexibility and making it difficult to replace or adjust the number of mounting frames, especially when dealing with varying wiring thickness or non-standard plug-in units.
Innovation Solution
A plug-in unit-mounting structure that utilizes removable mounting frames with adjustable guide rails and connectors on a back wiring board, allowing plug-in units of various sizes and shapes to be mounted without fixed guide rails on the shelf, enabling high flexibility in design and configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If guide rails are fixed to the shelf, then the mounting structure is stable and simple, but it limits flexibility when mounting plug-in units of different sizes and makes it difficult to replace or adjust mounting frames
Solution Approach 1:
The mounting structure is divided into separate components: the shelf with fixed guide rails, and removable mounting frames that can be independently attached and detached. This segmentation allows the guide rails to remain simple and fixed while the mounting frames provide the necessary adaptability for different plug-in unit sizes.
Solution Approach 2:
The mounting frames are designed to be removable and replaceable, transforming the static fixed mounting structure into a dynamic system where mounting frames can be adjusted, removed, or replaced based on the specific plug-in unit requirements, thereby providing flexibility without complicating the overall structure.
2Adaptability or versatility
If guide rails are made adjustable to accommodate different plug-in unit sizes, then adaptability improves, but the structure becomes more complex and harder to manufacture
Solution Approach 1:
By separating the guide rails (fixed and simple to manufacture) from the mounting frames (removable and customizable), the structure maintains manufacturing simplicity while achieving adaptability through the replaceable mounting frames that can be configured for different sizes.
Solution Approach 2:
The mounting frames serve as universal components that can be configured to accommodate different plug-in unit sizes and types. A single mounting frame design can be used across multiple positions and configurations, simplifying manufacturing while providing the needed versatility.
3Productivity
If the number of mounting frames is increased to handle more plug-in units, then productivity increases, but the device complexity and space requirements increase
Solution Approach 1:
The mounting frames are designed as universal, standardized components that can be repeatedly used in the same or different positions. This universality allows increasing the number of mounted plug-in units by simply adding more identical mounting frames rather than designing complex custom structures, thereby improving productivity without proportionally increasing device complexity.
4Adaptability or versatility
If fixed guide rails are used on the shelf, then the structure is simple and stable, but it cannot accommodate non-standard or varying thickness plug-in units
Solution Approach 1:
The removable mounting frames introduce dynamic adjustability to the system, allowing them to be easily detached and replaced to accommodate varying thickness and non-standard plug-in units, while the fixed guide rails maintain structural simplicity and stability.
Solution Approach 2:
The mounting frames act as intermediary components between the fixed guide rails and the diverse plug-in units. They provide the necessary adaptability interface, allowing standard fixed rails to work with non-standard plug-in units by mediating the connection and alignment.

AI summary
A plug-in unit-mounting structure which makes it possible to efficiently mount plug-in units having different sizes in all slots. PIUs of printed board type which are different in size are mounted using respective mounting frames associated therewith. Box-shaped PIUs are also mounted using respective mounting frame associated therewith. However, no guide rail is provided on the metal shelf per se, for guiding each PIU for mounting the same therein.
