Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic card interconnection systems in computer calculation cabinets face limitations in connecting remote cards, accommodating a large number of daughter boards, adapting to cabinet geometry, and allowing coplanar connections, making them difficult to install and transport.
Innovation Solution
An electronic card interconnection system comprising a front and rear wall with connection means and cables, allowing connections from both sides and at significant distances, with adjustable flanges and fixing elements for secure assembly and flexibility, enabling easy installation and adaptation to cabinet geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a main electronic board with connectors is used to interconnect daughter boards in planes, then interconnection of boards is achieved, but interconnection of remote electronic boards at significant distances is not possible
Solution Approach 1:
The system divides the interconnection function into multiple independent connection means distributed on front and rear walls, each capable of connecting to electronic boards at different positions. This segmentation allows remote boards to be interconnected by selecting appropriate connection means on each wall, overcoming the distance limitation of a single main board approach.
2Adaptability or versatility
If the cabinet geometry is fixed, then the cabinet structure is simple, but adaptation to different cabinet geometries is not possible
Solution Approach 1:
The connection means are designed with universal functionality to accommodate different cabinet geometries. Each connection means can serve multiple purposes: connecting to various board types, adapting to different wall positions, and working with diverse cabinet configurations. This multi-functionality enables the system to adapt to different cabinet geometries without requiring geometry-specific components.
3Ease of operation
If electronic cards are connected on opposite sides of the cabinet, then remote interconnection is achieved, but coplanar connection is not possible
Solution Approach 1:
The system utilizes the third dimension (depth) by placing connection means on both front and rear walls of the cabinet. This dimensional approach allows electronic cards to be connected in coplanar arrangements on the same wall or in remote interconnections across opposite walls, providing flexibility in connection arrangement while maintaining coplanarity when needed.
4Reliability
If a fixed interconnection system is installed in the cabinet, then stable connection is achieved, but easy installation and disassembly are not possible
Solution Approach 1:
The system employs dynamic mounting mechanisms that allow the connection means to be easily installed and removed from cabinet walls while maintaining stable connections during operation. The mounting system transitions from a static fixed state to a dynamic removable state, enabling both installation ease and connection reliability.
