Solution Overview

Problem

Existing connectors face complex and time-consuming assembly processes due to the one-piece insulative base, leading to instability and resource wastage, especially in compact designs where terminal hole gaps are minimized.

Innovation Solution

The connector is designed with a separable insulative base and plastic core, utilizing a guiding pillar and engaging blocks for easy assembly, allowing slidable fit and repeated use of components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the insulative base is designed as a one-piece body, then the connector structure is simple and manufacturing is easier, but the assembly process becomes complicated and time-consuming

Engineering Contradiction:
Improveease of manufactureVSAvoidassembly efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The insulative base is divided into two separate parts: a stationary insulative base and a movable insulative core. This segmentation allows the core to be independently assembled and disassembled from the base, significantly simplifying the assembly process and improving productivity while maintaining manufacturing simplicity.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If the connector components are tightly integrated, then the connector becomes more compact, but the assembly difficulty increases due to shortened gaps between terminal holes

Engineering Contradiction:
Improveconnector compactnessVSAvoidassembly difficulty
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The movable insulative core is inserted into the stationary insulative base, forming a nested structure. The core fits within the base cavity, maintaining compact dimensions while providing clear assembly paths through the opening of the base, thus reducing assembly difficulty despite the compact design.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Device complexity

If the insulative base and plastic core are integrated, then the connector structure is simplified, but the stability after assembly is insufficient

Engineering Contradiction:
Improvestructural simplicityVSAvoidassembly stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The movable insulative core can slide within the stationary insulative base along the sliding direction, creating a dynamic yet stable connection. This sliding mechanism ensures firm positioning during operation while allowing for assembly and disassembly, thereby improving assembly stability without excessive structural complexity.

Inventive Principle:
Principle #15Dynamics

4Device complexity

If connectors are designed for single-use, then the structure can be simpler, but resources are wasted and economic efficiency decreases

Engineering Contradiction:
Improvestructural simplicityVSAvoidresource waste
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The movable insulative core and conductive terminals can be easily removed from the stationary insulative base for recovery and repeated use. This design enables the separation and reuse of valuable components, reducing resource waste and improving economic efficiency while maintaining simple connector structure.

Inventive Principle:
Principle #34Discarding and recovering
