Solution Overview

Problem

Existing relay modules are difficult to use due to a hard-to-toggle handle structure and challenging metal pin alignment during assembly, leading to inconvenience and complexity in the assembly process.

Innovation Solution

A relay module structure featuring a relay with a main body and pins, a loading box with a flexible latch portion, and a relay seat with a recess and terminal holes, where the flexible latch allows for easy separation and alignment through an externally exerted force, eliminating the need for a handle and simplifying assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a handle structure is used to eject the relay from the relay seat, then the relay can be removed, but the handle is hard to toggle and causes inconvenience in using

Engineering Contradiction:
Improveconvenience of removing relayVSAvoidhandle structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent removes the handle structure entirely from the relay module. Instead of using a handle to eject the relay, the design extracts this component and replaces it with a direct push-eject mechanism where the relay can be removed by simply pushing it, eliminating the complex handle toggling mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the operational parameter of relay removal from requiring handle toggling motion to simple linear pushing motion. This parameter change simplifies the user interaction from complex rotational/toggling movements to basic linear force application.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If metal pins are used to connect relay to relay seat, then electrical connection is established, but the pins are hard to align with and insert into terminal holes causing difficulty in assembling

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidassembly difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent incorporates preliminary alignment features on the metal pins that guide them into the terminal holes before insertion. This preliminary action of alignment ensures that the pins are automatically positioned correctly during the assembly process, eliminating the difficulty of manual alignment while maintaining reliable electrical connection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces alignment guides or positioning structures as intermediary elements between the metal pins and terminal holes. These intermediaries facilitate the alignment process by providing a pathway or guide that ensures proper positioning during assembly, making the connection process easier while maintaining connection reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The disclosure is a relay module structure (1). A relay (10) includes a main body (11) and multiple pins (12) connected to the main body (11). A loading box (20) includes a box body (21) receiving the main body (11) and a flexible latch portion (22) connected to the box body (21). The box body (21) has a force exerting portion (211) and multiple slots (212). The pins (12) project from the slots (212). A relay seat (30) includes a seat body (31) having a recess (311), a positioning portion (312) and terminal holes (313). The loading box (20) is inserted in the recess (311) by engagement between the flexible latch portion (22) and the positioning portion (312). The pins (12) are inserted in the terminal holes (313). The flexible latch portion (22) is separated from the positioning portion (312) by exerting a force on the force exerting portion (211) to make the loading box (20) separate from the relay seat (30).
