Solution Overview

Problem

The existing feeder units for electromagnetic valves require manual and time-consuming assembly and connection processes, involving the insertion of feeder cables and terminals into holes or cylinders, which complicates the assembly of the feeder socket and its attachment to the electromagnetic valve.

Innovation Solution

The electromagnetic valve features a feeder unit with a power receiving terminal on its side surface, a terminal cover, and a socket hole, where the feeder socket is assembled by interposing the feeder cable and terminal between a rectangular terminal storage box and its lid, eliminating the need for external insertion, using semi-circular grooves, elastic walls, and hooks for secure engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the feeder cable and terminal are inserted into a hole or cylinder formed in the socket body, then the feeder socket can be assembled, but the assembly process becomes manual and time-consuming

Engineering Contradiction:

Improveassembly processVSAvoidassembly time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The feeder socket is divided into two main segments: a terminal storage box for holding the feeder cable and terminal, and a lid that covers the open front surface. This segmentation eliminates the need for complex hole-forming operations in a single body, allowing for simpler, faster assembly of the feeder socket components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of forming holes or cylinders in the socket body to receive the feeder cable and terminal, the invention inverts the approach by creating a terminal storage box with an open front surface that naturally accommodates these components, then covering it with a lid. This reverses the traditional manufacturing sequence and simplifies the assembly process.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of manufacture

If the terminal storage box and lid are assembled by inserting components into holes, then the feeder socket can be formed, but the process becomes complex and difficult

Engineering Contradiction:

Improveassembly processVSAvoidassembly complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The feeder socket is segmented into a terminal storage box and a lid, each with simple geometries that are easy to manufacture. The terminal storage box has an open front surface that directly receives the feeder cable and terminal without requiring complex hole-forming operations, significantly reducing assembly complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention transitions from a three-dimensional hole-forming operation within a solid body to a two-dimensional surface assembly approach. The open front surface of the terminal storage box allows the feeder cable and terminal to be placed from the front, changing the assembly dimension and eliminating complex internal cavity formation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the feeder cable is inserted into a hole or cylinder in the socket body, then electrical connection can be established, but the assembly requires manual operations

Engineering Contradiction:

Improveassembly operationVSAvoidassembly time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The terminal storage box is segmented to have an open front surface that allows direct placement of the feeder cable and terminal, eliminating the need for manual insertion into deep holes or cylinders. This segmentation enables a simple drop-in assembly operation that is both easier and faster to perform.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The terminal storage box is pre-configured with an open front surface and appropriate internal structure to receive the feeder cable and terminal in their final positions. This preliminary preparation of the storage box geometry eliminates the need for subsequent manual insertion operations, allowing for rapid assembly.

Inventive Principle:

AI summary

A feeder terminal connected to the core wire of the feeder cable is installed in the storage chamber of the terminal storage box, and the feeder cable and the feeder terminal are gripped to be fixed between the terminal storage box and the lid such that the feeder socket is assembled. The feeder socket is inserted into the socket hole formed in the terminal cover to connect the feeder terminal to the power receiving terminal communicated with the electromagnetic operation unit.
