Solution Overview

Problem

Conventional connector terminals restrict the insertion direction of terminals due to their four-cornered socket housing design, limiting the number of possible insertion directions to three.

Innovation Solution

A connector terminal design featuring a single plate with paired flat plate portions and a support portion that allows insertion from various directions, including 180 or 360 degrees, by using a fitting protruding and recess portion mechanism to prevent separation and enhance stiffness without additional components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the socket housing is formed into a chassis with four corners linked by link portions, then the structural integrity is maintained, but the number of insertion directions is limited to three

Engineering Contradiction:
Improveinsertion directionsVSAvoidsocket housing structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The socket housing is divided into a body portion and separate link portions. The link portions are detachably connected to the body portion, allowing the structure to be segmented and reconfigured. This segmentation enables the link portions to be positioned in different orientations, thereby increasing the number of possible insertion directions beyond the traditional three, while maintaining structural integrity through the detachable connection mechanism.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the link portions are detachably connected to the body portion, then the insertion directions are increased, but the structural stability may be compromised

Engineering Contradiction:
Improveinsertion directionsVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The link portions are pre-formed with specific connection structures that enable detachable attachment to the body portion. These pre-configured connection mechanisms ensure that when the link portions are attached, they form stable connections that maintain structural integrity. The preliminary design of the connection structures allows for multiple insertion directions while ensuring that once assembled, the overall structure remains stable and reliable.
