Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate connectors are used for connecting system components, then connection reliability is improved, but device complexity and weight increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the connector functions directly into the rigging plate by integrating load pins and track pins with locking assemblies into the plate structure itself, eliminating the need for separate external connectors while maintaining connection reliability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rigging plate is designed with multiple load pins and track pins that can accept various system components, making the plate itself a multi-functional device that serves both as structural support and connection mechanism, reducing overall system complexity

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

2Strength

If separate connectors are used for connecting system components, then connection strength is improved, but weight increases

Engineering Contradiction:
Improveconnection strengthVSAvoiddevice weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

By merging the connector functions into the rigging plate structure, the patent eliminates redundant components and their associated weights, achieving connection strength through the integrated pin and locking assembly design without the added weight of separate connectors

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If load pins are secured with locking assemblies, then connection reliability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidease of connecting and disconnecting
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking assembly incorporates a movable lock pin that can transition between locked and unlocked positions, allowing the connection to be secure during operation but easily released when needed, balancing reliability with operational ease

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The biasing member automatically maintains the lock pin in the locked position and enables easy release through the track slot mechanism, reducing the effort required for operation while ensuring reliable locking during service

Inventive Principle:
Principle #25Self-service

4Reliability

If biasing members are used to maintain locked position, then connection reliability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The biasing member creates a self-acting locking mechanism that automatically maintains the lock pin in the locked position without requiring external actuators or complex control systems, achieving reliability through simple passive mechanical means

Inventive Principle:
Principle #25Self-service

AI summary

A securement device is disclosed to aid in the movement or suspension of equipment or people through the air or along inclined surfaces using rope, cable, wire, or similar component and associated lifting, winching, lowering devices, mechanical advantage systems or manual power by retaining a system component between a yoke and a load pin using a load pin assembly. The load pin is biased into a locked position through the use of a biasing member but may be moved from a locked position to a retracted position by journaling a lock pin through a lock slot. Some embodiments restrict movement of the load pin using a track pin and a track slot, while other embodiments use the interaction of a lock ring and a keyed recess formed in the yoke. The securement device may be incorporated as part of a rigging plate.
