Solution Overview

Problem

Existing connectors with position assurance elements lack a straightforward method to verify a secure connection to a mating plug and are not compact enough.

Innovation Solution

The position assurance element is designed with a contact receptacle identical to those in the connector housing, allowing it to serve as an electrical contact element, ensuring a secure connection is confirmed by an established electrical connection, and maintaining a compact design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the position assurance element is designed with a contact receptacle identical to those in the connector housing, then verification of secure connection is simplified and device complexity is reduced, but the position assurance element requires additional structural components

Engineering Contradiction:
Improveconnector structureVSAvoidposition assurance element manufacturing
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The patent combines the position assurance function with the electrical contact function by integrating a contact receptacle into the position assurance element. This merging of functions allows the position assurance element to serve dual purposes: securing the mechanical connection and enabling electrical contact verification, thereby simplifying the overall connector structure without significantly complicating manufacturing

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The position assurance element is designed with multi-functionality, serving both as a mechanical positioning/locking component and as an electrical contact component. The integrated contact receptacle allows the same element to verify both mechanical connection status and electrical connection status, reducing the need for separate verification mechanisms

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If the contact receptacle in the position assurance element is made substantially identical to contact receptacles in the connector housing, then manufacturing consistency is improved and part standardization is achieved, but the position assurance element occupies additional space

Engineering Contradiction:
Improvecontact receptacle standardizationVSAvoidposition assurance element volume
Core Design Contradiction:
Ease of manufactureVSVolume of moving object

Solution Approach 1:

The patent applies homogeneity by making the contact receptacle in the position assurance element substantially identical to the contact receptacles in the connector housing. This standardization allows for consistent manufacturing processes, interchangeable components, and simplified quality control, while the compact integration minimizes the additional volume required

Inventive Principle:
Principle #33Homogeneity

3Difficulty of detecting and measuring

If the position assurance element includes an integrated contact receptacle for electrical contact verification, then connection status detection is simplified and measurement precision is improved, but the position assurance element structure becomes more complex

Engineering Contradiction:
Improveconnection status verificationVSAvoidposition assurance element structure
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The position assurance element performs self-verification of connection status through its integrated contact receptacle. When the connectors are mated, the electrical contact through the position assurance element's receptacle automatically indicates proper connection, eliminating the need for separate detection systems or additional verification steps

Inventive Principle:
Principle #25Self-service
