Solution Overview

Problem

Angled connectors experience mechanical and electrical connection issues due to strain when force is applied to the cable end, leading to potential damage and unreliable connections.

Innovation Solution

The angled connector features a positive-locking arrangement of insulating and housing parts that distribute forces perpendicular to the insertion direction, using anti-rotation elements to secure the insulating body and housing parts together, ensuring stable electrical connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the connector uses an angled cable end design, then the connector can be inserted into a complementary connector receptacle in a specific insertion direction, but the angled cable end puts great strain on the mechanical and electrical contact between the connector and the receptacle when force is applied

Engineering Contradiction:
Improveinsertion directionVSAvoidmechanical and electrical contact
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connector is divided into multiple segments: a first connector section that forms an angle with a second connector section, and a positive-locking arrangement that can move between locked and unlocked positions. This segmentation allows the connector to maintain its angled insertion capability while isolating the strain from the electrical contacts through the movable locking mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The positive-locking arrangement is designed to be movable between a locked position (where it engages with the receptacle) and an unlocked position (where it disengages). This dynamic design allows the connector to adapt to applied forces by transitioning between states, preventing force transmission to the electrical contacts while maintaining connection stability when locked.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the connector uses a fixed positive-locking arrangement, then the electrical connection is stable, but the connector cannot be easily assembled and disassembled

Engineering Contradiction:
Improveelectrical connection stabilityVSAvoidassembly and disassembly
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The positive-locking arrangement is designed as a movable component that can transition between locked and unlocked positions. When locked, it provides stable electrical connection; when unlocked, it allows easy assembly and disassembly. This dynamic design resolves the contradiction by providing both stability during operation and ease of handling during maintenance.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connector incorporates a self-locking mechanism that automatically engages when the connector is inserted into the receptacle, providing stable electrical connection without requiring additional fastening steps. Conversely, applying force in a specific direction automatically unlocks the mechanism, enabling easy disassembly without tools or complex procedures.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the connector allows force application to the cable end, then the connector is easy to operate, but the mechanical and electrical connection becomes unreliable due to strain

Engineering Contradiction:
Improvecable end operationVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The positive-locking arrangement is designed to move in response to forces applied to the cable end. When force is applied during operation, the locking mechanism can transition from locked to unlocked state, preventing force transmission to the electrical contacts. This dynamic response maintains connection reliability while preserving ease of operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The positive-locking arrangement acts as an intermediary between the cable end and the electrical contacts. It absorbs and isolates forces applied to the cable end, preventing them from reaching the mechanical and electrical connection points. This intermediary function allows easy operation at the cable end while protecting the connection reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)
