Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional electrical connection methods are used, then reliable electrical connection is achieved, but assembly complexity and time increase

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The connector is designed with self-alignment features including a conical guide portion that automatically centers the connector with the mirror support during assembly, and a self-retaining mechanism with snap-fit elements that secure the connection without additional fastening steps. This self-service design ensures reliable electrical connection while eliminating complex assembly procedures.

Inventive Principle:

Principle #25Self-service

2Reliability

If traditional electrical connection methods are used, then reliable electrical connection is achieved, but assembly time increases

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The connector is pre-configured with a conical guide portion and snap-fit retention elements that enable automatic alignment and secure attachment during a single insertion motion. This preliminary design of the connection mechanism allows the assembly to be completed in one action, significantly reducing assembly time while maintaining reliable electrical connection.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If precise allocation of openings and pins is required, then reliable electrical connection is achieved, but manufacturing precision requirements increase

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidopening and pin alignment precision

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The connector incorporates a conical guide portion with a tapered surface that guides the connector into proper alignment with the mirror support. This curved, self-centering geometry compensates for minor dimensional variations and misalignments, reducing the stringency of manufacturing precision requirements while ensuring reliable electrical connection through proper pin-to-opening engagement.

Inventive Principle:

Principle #14Spheroidality (Curvature)
