Solution Overview

Problem

Existing lockbox systems lack a secure and efficient mechanism for selectively coupling components, which can be vulnerable to unauthorized access and tampering.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a locking mechanism is designed to be secure and resistant to tampering, then reliability and security are improved, but device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoidcomplexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is divided into distinct functional segments: locking fingers for engagement, a biasing mechanism for automatic resetting, and an actuator for controlled operation. This segmentation allows each component to perform its specific function efficiently while maintaining overall security without excessive complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The biasing mechanism automatically returns the locking fingers to the locked position after actuation, eliminating the need for additional reset mechanisms or manual intervention. This self-service feature enhances security reliability while minimizing the complexity of control systems required

Inventive Principle:
Principle #25Self-service

2Ease of operation

If a locking mechanism uses spring-loaded locking fingers with biasing mechanism, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoidcomplexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The locking fingers are designed as dynamic, spring-loaded elements that can move between locked and unlocked positions. This dynamic design allows automatic engagement and disengagement based on actuator position, improving ease of operation while the modular spring mechanism keeps complexity manageable

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The biasing mechanism creates a periodic action where the locking fingers automatically return to the locked position after being actuated. This periodic resetting action simplifies operation by eliminating manual reset steps while the repetitive mechanical action keeps the system relatively simple

Inventive Principle:
Principle #19Periodic action

AI summary

A locking module for selectively coupling a first component and a second component of a lockable device includes a locking element including a plurality of locking fingers movable between an open position and a closed position. The plurality of locking fingers being biased to said open position. A biasing mechanism is coupled to said locking element and a compression force applied by said biasing mechanism to said plurality of locking fingers controls movement of said plurality of locking fingers between said open position and said closed position. An actuator associated with said biasing mechanism is operable to control said compression force to selectively lock said locking element
