Solution Overview

Problem

Existing multifunctional high-voltage connectors in battery products face challenges with low assembling efficiency and accuracy due to the integration of multiple functions, which complicates the mounting and detachment between the upper cover and the pedestal.

Innovation Solution

A multifunctional high-voltage connector design featuring a pedestal and an upper cover with oblique-port structures and guide portions that facilitate easy assembly and ensure accurate mounting, improving efficiency and accuracy by reducing weight and providing visual positioning guides.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple functions are integrated into a single connector, then the device complexity is reduced and productivity is improved, but the mounting and detachment process becomes more difficult

Engineering Contradiction:
Improveassembling efficiencyVSAvoidmounting complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The connector is divided into an upper cover and a pedestal that can be detachably assembled. The upper cover includes an outer shell and an inner shell, while the pedestal includes an outer base and an inner base. This segmentation allows for easier manufacturing, assembly, and maintenance while still achieving the multifunctional integration benefit.

Principle #1Segmentation

2Manufacturing precision

If guide portions are added to improve assembly accuracy, then manufacturing precision is improved, but the device complexity increases

Engineering Contradiction:
Improveassembling accuracyVSAvoidstructure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The guide portions utilize asymmetric geometric features including oblique-port portions with specific angles (5≤θ≤8 degrees), protrusions, and recessed grooves. These asymmetric features provide precise positioning and guidance during assembly without requiring complex adjustment mechanisms, thereby improving assembling accuracy while maintaining structural simplicity.

Inventive Principle:
Principle #4Asymmetry
