Solution Overview

Problem

Electric connectors lack protection against unintended manipulation, which can lead to unsafe situations such as sparking, arcing, or burning, particularly in applications where they are not safeguarded against accidental loosening or manipulation under load.

Innovation Solution

Incorporating a pressure-sensitive surface and a pressure sensor to detect pressure changes, with an optional alarm unit that alerts operators to potential disengagement and can interrupt power supply to prevent accidents, along with a locking feature to ensure secure connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pressure sensor and alarm unit are added to detect manipulation, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improveconnector reliabilityVSAvoidconnector structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The pressure sensor is installed on the locking feature to detect pressure changes before unintended disengagement occurs. The alarm unit is pre-configured to trigger at predetermined pressure thresholds, providing advance warning of potential manipulation or loosening events, allowing corrective action before dangerous situations develop.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pressure sensor continuously monitors the pressure state of the locking feature and provides real-time feedback to the alarm unit. When pressure changes indicate manipulation or loosening, the system immediately responds by activating the alarm, creating a closed-loop monitoring system that enhances connector reliability through continuous surveillance and immediate response.

Inventive Principle:
Principle #23Feedback

2Object-affected harmful factors

If alarm unit interrupts power supply to prevent accidents, then safety is improved, but loss of information may occur

Engineering Contradiction:
Improvesparking and arcing preventionVSAvoiddata transmission interruption
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The alarm unit selectively interrupts only the power supply function when manipulation is detected, while potentially leaving data transmission channels intact if they are separate. This partial action approach stops the harmful effect (sparking under load) without completely shutting down all connector functions, minimizing information loss while ensuring safety.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system provides advance warning through the alarm unit before complete power interruption occurs. This gives operators time to take protective measures or save critical data before the power supply is cut off, cushioning against the potential loss of information while still preventing the harmful sparking condition.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
