Relay Pin Assembly via Longitudinal Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of relay devices is complicated due to directional limitations in the assembly of pins and brackets, leading to increased manufacturing time and costs, as the assembly directions differ before and after processing, making it difficult to perform once assembly in an automatic machine.
Innovation Solution
A relay device design featuring a base with a peripheral gap for pin assembly without directional limitations, combined with an electromagnet and control mount, and an outer cap with a receiving groove, where the pin has a convex plate covering the gap and a bent section with magnetic sheets for elastic connection, allowing for simplified assembly and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the bracket and pin are assembled with directional limitations as in conventional designs, then the assembly structure provides precise positioning, but the assembly process becomes complicated and cannot be completed in a single direction
Solution Approach 1:
The patent inverts the conventional assembly approach by designing the pin to be inserted along the longitudinal direction of the electromagnetic coil instead of the lateral direction. This inversion allows the pin to pass through the base and coil assembly in a single straightforward motion, eliminating the need for complex multi-directional assembly steps while maintaining precise positioning through the pin's convex plate and the base's gap structure
2Reliability
If multi-directional assembly steps are used to assemble the bracket and pin, then the assembly can be completed, but the manufacturing time increases
Solution Approach 1:
The patent merges the positioning and fastening functions into a single pin component that is inserted in one direction. The pin's convex plate works with the base's gap to provide positioning, while the pin itself provides fastening, eliminating the need for separate bracket components and multi-directional assembly steps. This consolidation reduces manufacturing time while ensuring complete and reliable assembly
3Stability of the object's composition
If the pin is laterally assembled to the electromagnetic coil as in conventional designs, then the assembly structure is stable, but the assembly direction is limited and complicates the manufacturing process
Solution Approach 1:
The patent changes the assembly dimension from lateral (horizontal) insertion to longitudinal (vertical) insertion along the electromagnetic coil's length. This dimensional change allows the pin to pass through the entire assembly in a single straightforward motion, improving manufacturability while maintaining stability through the pin's convex plate positioning feature that engages with the base's gap structure

AI summary
A relay device comprises a base, a pin, and an outer cap. A gap is arranged at a peripheral of the base. The pin has a convex plate and assembled to the gap of the base and one end thereof is protruded from the gap. The convex plate is covered/shielded the gap. The outer cap includes a receiving groove. A notch of the receiving groove is covered the base and the pin. A paste is applied among the peripheral of the base, the convex plate of the pin, and the notch of the receiving groove for fastening. The gap arranged at the peripheral of the base is providing the pin for assembling without directional limitation and advantageous to once assembly of the base and the pin in an automatic machine so as to simplify the manufacturing process of the relay device.
