Solution Overview
Problem
Existing electromagnetic relays face challenges in fabricating insulating structures that provide a high insulating effect while being easy to manufacture, as the complexity of these structures can complicate the fabrication process.
Innovation Solution
The electromagnetic relay incorporates an insulating member with an opening portion that allows the spool to be inserted and attached, featuring a base mold and disc-like shaped members around the spool to ensure insulation between the coil and other components, simplifying the attachment process while maintaining a high insulating effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insulating structure is complicated to provide high insulating effect, then the insulation performance is improved, but the fabrication complexity increases
Solution Approach 1:
The spool is inserted into the insulating member, creating a nested structure where the spool (cylindrical insulating component) fits inside the insulating member. This nesting approach provides effective insulation between the coil and other components while maintaining a compact and relatively simple overall structure that is easy to fabricate.
2Reliability
If the insulating structure is complicated to provide high insulating effect, then the insulation performance is improved, but the fabrication difficulty increases
Solution Approach 1:
The insulating structure is divided into separate components: the insulating member and the spool. These segmented components can be manufactured independently using standard fabrication processes, then assembled by inserting the spool into the insulating member. This segmentation simplifies the manufacturing of each individual component while achieving the required insulating effect through their combined arrangement.
3Reliability
If the insulating structure is complicated to provide high insulating effect, then the insulation performance is improved, but the assembly process becomes more difficult
Solution Approach 1:
The spool is designed to be inserted into the insulating member, creating a nested configuration. This nesting design simplifies assembly as the spool can be directly inserted into the insulating member without complex alignment or fastening operations. The insertion-type attachment reduces assembly complexity while maintaining effective insulation between the coil and other relay components.
