Relay Coil Connection Positioning for Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of relays with coil connections on the outer surface can lead to an increase in size, which is undesirable for compactness and efficient packaging.
Innovation Solution
The coil connection is strategically positioned to overlap with non-overlapping portions of the bus bar or external connections, effectively utilizing dead spaces within the relay's structure, thereby preventing size expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the coil connection is disposed on the outer surface of the relay case, then the ease of connecting the coil driving cable is improved, but the size of the relay increases
Solution Approach 1:
The patent applies dimensional arrangement by positioning the coil connection in the width direction (lateral dimension) of the relay case, rather than extending in the length direction. This allows the coil connection to utilize otherwise unused space on the outer surface, achieving easy cable connection without increasing the overall relay size in the primary dimension.
Solution Approach 2:
The patent positions specific components (coil connection and bus bar) in specific locations where they do not overlap when viewed from the width direction. This local spatial arrangement allows the coil connection to be accessible on the outer surface while maintaining compact overall dimensions by utilizing localized dead spaces.
2Ease of operation
If the coil connection is disposed on the outer surface of the relay case, then the ease of connecting the coil driving cable is improved, but the device complexity increases
Solution Approach 1:
The patent merges the coil connection with the bus bar structure, where the bus bar serves dual purposes: electrical connection and structural support for the coil connection. This integration reduces the number of separate components and simplifies the overall structure while maintaining ease of coil cable connection.
3Ease of operation
If the bus bar is extended outside the case for external connection, then the ease of external connection is improved, but the space for internal component arrangement is reduced
Solution Approach 1:
The patent arranges the bus bar to extend in the width direction (lateral dimension) rather than the length direction, allowing external connections to be made without compromising the internal space needed for coil and触头 arrangement. This dimensional strategy enables both easy external connection and adequate internal component placement.
Solution Approach 2:
The bus bar is segmented into different portions: one part extends outside the case for external connection, while another part remains inside to connect with internal components. This segmentation allows the bus bar to fulfill multiple functions without interfering with internal space requirements.
