Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the connector position assurance is formed as a separate part and coupled to the connector housing, then the locking lever can be supported to prevent connector separation, but the user must perform complex operations (pulling backward before combining, pushing back after combining) and the operability is reduced

Engineering Contradiction:
Improveconnector connection reliabilityVSAvoidconnector combination operability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connector position assurance is merged with the locking lever to form an integrated structure. The locking lever and connector position assurance are no longer separate parts but are combined into a single component, eliminating the need for separate assembly and disassembly operations. This integration maintains the support function while significantly improving operability by reducing the number of manual manipulation steps required during connector combination.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If the connector position assurance is pushed forward to the lock position before coupling, then the locking lever is already locked, but it becomes difficult to pull out the connector position assurance and combine the other connector

Engineering Contradiction:
Improvelocking lever lock stabilityVSAvoidconnector position assurance adjustability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connector position assurance is designed with dynamic movement capability along the insertion direction. It can move forward to engage with the locking lever for support, and can also be pulled backward along the same direction to disengage. This dynamic positioning allows the connector position assurance to adapt its position during different stages of connector combination, maintaining both locking stability and operational flexibility.

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If many complicated conductive parts are used for forming electric shield and grounding paths, then the shield function can be achieved, but the contact point stability and reliability between conductive parts is difficult to ensure and assembly becomes complex

Engineering Contradiction:
Improvenoise reduction effectivenessVSAvoidshield parts complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Multiple conductive parts for electric shield and grounding paths are merged into an integrated shield structure. Instead of using separate complicated conductive parts that require multiple contact points and assembly steps, the invention combines these functions into a unified design that reduces the number of components and simplifies assembly while maintaining effective noise shielding and grounding.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A shield connector includes: a female connector having a female terminal connected to a shield wire and a locking protrusion; a male connector having a male terminal connected to the female terminal when the male connector is combined with the female connector, and a coupling protrusion to which the locking protrusion is locked for locking with the female connector; and a connector position assurance that is combined with the female connector to be movable forward/backward and has support levers that support the locking protrusion and prevent the locking protrusion from being unlocked from the coupling protrusion when the connector position assurance is moved forward, in which locking steps are formed at the female connector, and an insertion portion is formed at the male connector.
