Solution Overview

Problem

Existing connectors lack flexibility and efficient actuation mechanisms, particularly in tight spaces and with multiple connectors, making plugging and unplugging cumbersome and inefficient.

Innovation Solution

A connector design featuring a cable kink protection unit that is directly actuable for locking and unlocking, integrated with a spring-mounted locking unit, allowing translational movement to facilitate easy plugging and unplugging, and incorporating a flexible, rotationally symmetrical cable kink protection with a minimum bending radius to prevent damage and enhance protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate actuating tool is used to actuate the locking unit, then the locking mechanism can be actuated, but the device complexity increases and handling becomes cumbersome

Engineering Contradiction:
Improvehandling easeVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cable kink protection is merged with the actuation function by providing a protrusion that directly contacts the locking unit. This integration eliminates the need for separate actuating tools, allowing the user to actuate the locking mechanism by simply pulling or pushing the cable kink protection, thereby reducing device complexity while improving ease of operation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cable kink protection serves multiple functions: it protects the cable from kinking and damage, and simultaneously acts as the actuating element for the locking unit. This multi-functionality reduces the number of separate components needed, simplifying the overall structure while maintaining ease of use

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

2Ease of operation

If the locking unit is translationally immovable, then the structure is simplified, but the ease of operation for locking and unlocking is reduced

Engineering Contradiction:
Improvelocking and unlocking easeVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The locking unit is designed to be translationally movable along the longitudinal axis, allowing it to shift between locked and unlocked positions. This dynamic capability enables easy actuation through the protrusion on the cable kink protection, improving ease of operation while maintaining relatively simple structure through linear movement rather than complex mechanisms

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the cable kink protection is rigid, then the structural strength is improved, but the flexibility and space efficiency are reduced

Engineering Contradiction:
ImproveflexibilityVSAvoidstructural strength
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The cable kink protection is designed as a flexible component that can bend and deform to accommodate cable movements and tight installation spaces. This flexibility improves adaptability and ease of installation while the protrusion feature provides sufficient structural engagement with the locking unit to maintain functional strength

Inventive Principle:
Principle #30Flexible shells and thin films
