Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional rectangular connector design is used, then manufacturing is simple, but alignment during insertion is difficult and connector size is larger

Engineering Contradiction:
Improvealignment during insertionVSAvoidconnector geometry
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connector employs a tapered geometry where the distal end is narrower than the proximal end, creating a conical shape that facilitates self-alignment during insertion. This curved/tapered form replaces the traditional rectangular prism shape, enabling automatic orientation and reducing misalignment issues while maintaining manufacturability through standard molding processes.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Length of moving object

If connector length is reduced for compactness, then device size decreases, but connection stability and signal integrity may worsen

Engineering Contradiction:
Improveconnector lengthVSAvoidconnection stability
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The tapered conical shape allows the connector to achieve compact length while maintaining connection stability. The narrowing toward the distal end creates a precise fitting interface that ensures stable electrical contact, while the overall shortened form factor enables compact device design without compromising reliability.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Volume of moving object

If connector size is reduced for portability, then device portability improves, but manufacturing precision requirements increase

Engineering Contradiction:
Improveconnector volumeVSAvoidtaper angle precision
Core Design Contradiction:
Volume of moving objectVSManufacturing precision

Solution Approach 1:

The connector design utilizes specific taper angle parameters that balance compactness with manufacturability. By optimizing the taper angle within a defined range, the design achieves reduced volume while maintaining manufacturing feasibility through standard precision molding capabilities, avoiding excessively tight tolerance requirements.

Inventive Principle:

AI summary

An electronic connector includes a base, a tapered extension protruding from the base, and a nose forming a terminal end of the tapered extension. The tapered extension includes first and second connection faces tapering toward each other from the base to the nose symmetrically about a first symmetry plane. The tapered extension further includes first and second flank surfaces that form respective opposing sides of the tapered extension between the first and second connection faces. The first and second flank surfaces may taper toward each other from the base to the nose symmetrically about a second symmetry plane. The tapered extension further includes a set of electrical contacts located along the first and second connection faces. The electronic connector may further include one or more magnetically attractable elements.
