Electromagnetic Relay Partition Wall Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromagnetic relays are prone to warping or deformation due to temperature changes during the curing of bonding agents used to fix the case and body together.
Innovation Solution
The electromagnetic relay incorporates partition walls inside the case and corresponding latching parts on the body, with the tip end of each partition wall being latched onto the latching part using a bonding agent, and a regulation part to control the movement of the bonding agent, ensuring secure bonding and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the case and body are fixed together using bonding agents, then the assembly is secured, but the body warps or deforms due to temperature changes during curing
Solution Approach 1:
The case is divided into multiple partition walls that are bonded to different locations on the body, distributing the bonding stress and reducing localized deformation. The partition walls create separate bonding zones rather than a single large bonded area.
Solution Approach 2:
The partition walls are strategically positioned at specific locations on the body where bonding is most effective. Each partition wall creates a localized bonding region with optimized geometric features for adhesion, concentrating bonding strength where needed while minimizing overall deformation.
2Stability of the object's composition
If partition walls are added inside the case to prevent deformation, then structural integrity is improved, but device complexity increases
Solution Approach 1:
The partition walls serve multiple functions: they provide structural support to prevent body deformation, create bonding surfaces for attachment to the body, and maintain internal case structure. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The partition walls are integrated directly into the case structure as a unified component rather than being separate attachments. The case and partition walls form a single molded structure, eliminating the need for additional assembly steps and reducing overall device complexity.

AI summary
An electromagnetic relay (1) is formed by assembling a drive part (30), mobile body (50) that moves when the drive part (30) is driven, and a plurality of contact mechanisms (60, 70) that switch the contact and separation of contacts (61d, 62d, 71d, 72d) by the movement of the mobile body (50) in a body (40). Furthermore, a partition wall (21) is provided inside a case (20), which is fitted over the body (40), and a latching part (42) is provided in a location on the body (40) corresponding to the partition wall (21). In the state where the case (20) is fitted over the body (40), the front end of the partition wall (21) is latched to the latching part (42).
