Solution Overview

Problem

Conventional connectors, particularly elbow female sockets, often experience issues such as terminal retraction, terminal deflection, and true position deviation due to structural design problems when connected to external devices.

Innovation Solution

A connector design featuring a sheet terminal with a bend section, mating section, and insertion section, along with an insulating base that includes a base with opposite sidewalls, a stop portion, and a mating portion, where the insertion section is accommodated in the base's accommodation space and the mating section is located in the mating space, utilizing shoulders, limiting slots, guide slots, and positioning slots to stabilize the terminal and prevent deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the connector uses a conventional structural design, then the device complexity is reduced, but terminal deformation and position deviation occur due to insufficient stability

Engineering Contradiction:

Improveterminal stabilityVSAvoidconnector structure complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The connector is divided into distinct functional sections: the insulating base with accommodation space, the sheet terminal with bend/mating/insertion sections, and the limiting portions. This segmentation allows each component to perform its specific function independently, improving terminal stability without requiring complex integrated structures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The limiting portions are pre-positioned within the accommodation space of the insulating base before the sheet terminal is fully inserted. This preliminary positioning prevents terminal deformation during the insertion process and ensures proper alignment, eliminating the need for complex adjustment mechanisms.

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If the insertion section is fully accommodated in the base, then the terminal positioning is improved, but the terminal may deform due to constrained space

Engineering Contradiction:

Improveterminal position precisionVSAvoidterminal structural integrity

Core Design Contradiction:

Manufacturing precisionVSStrength

Solution Approach 1:

The insulating base provides different types of support at different locations: the accommodation space constrains the insertion section for precise positioning, while the limiting portions provide localized support to prevent deformation. This differentiated local support system maintains both position precision and structural integrity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The limiting portions are positioned in advance to counteract potential terminal deformation before it occurs during insertion. By pre-establishing these support points, the terminal is protected from bending or twisting forces that would compromise its structural integrity.

Inventive Principle:

Principle #9Preliminary anti-action

3Reliability

If the connector lacks limiting portions, then the structure is simpler, but terminal retraction and deflection occur during connection

Engineering Contradiction:

Improveconnection reliabilityVSAvoidconnector component quantity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The limiting portions are integrated directly into the insulating base structure, eliminating the need for separate external support components. The insulating base itself provides the limiting function through its internal geometry, maintaining connection reliability without adding significant structural complexity.

Inventive Principle:

Principle #25Self-service

4Manufacturing precision

If the mating section is properly positioned, then the true position deviation is reduced, but additional positioning structures increase device complexity

Engineering Contradiction:

Improvemating section true positionVSAvoidpositioning structure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The positioning function for the mating section is merged with the insulating base structure. The base's accommodation space and limiting portions simultaneously perform multiple functions: supporting the insertion section, guiding the mating section, and preventing position deviation. This integration eliminates the need for separate positioning mechanisms.

Inventive Principle:

Principle #5Merging (Combining)
