Solution Overview

Problem

Existing turnstiles lack the ability to efficiently and selectively direct individuals into different lanes for access and exit control, particularly in securing facilities, as they often rely on manual operation and lack advanced mechanisms for random or strategic lane assignment.

Innovation Solution

A dual turnstile system equipped with a processor and passage mechanism that uses algorithms to randomly or strategically select which side to unlock for passage, incorporating sensors and biometric systems for real-time decision-making, and allowing manual control for security personnel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation is used for turnstile control, then ease of operation is improved, but productivity deteriorates due to inefficiency and bottlenecks

Engineering Contradiction:

Improveease of operationVSAvoidprocessing efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The turnstile system performs automatic lane selection and control without requiring manual operation. The processor automatically selects lanes based on algorithms (random selection, bias toward less-used lanes, or equal distribution) and controls the hub assemblies accordingly, allowing the system to serve itself and eliminating the need for manual control while maintaining high processing efficiency

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operation with an automated electronic control system. The processor, algorithms, and electronic control mechanisms substitute for manual human operation, enabling the turnstile to automatically direct individuals through different lanes based on programmed criteria rather than requiring manual intervention for each passage

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If fixed lane assignment is used, then device complexity is reduced, but adaptability deteriorates due to inability to respond to varying security needs

Engineering Contradiction:

Improvesystem complexityVSAvoidadaptability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The turnstile system dynamically adapts lane assignment based on different operational modes and criteria. The processor can switch between multiple algorithms (random selection, bias toward less-used lanes, equal distribution) and adjust lane selection in real-time based on security needs, traffic patterns, and operational requirements, making the system flexible and adaptable without requiring complex physical reconfiguration

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters (lane selection criteria, selection algorithms, control modes) to adapt to different security needs and operational scenarios. The processor can modify which algorithm is used, adjust bias levels toward less-used lanes, and change control modes based on security requirements, allowing the same physical system to adapt to varying conditions through parameter changes rather than structural modifications

Inventive Principle:

Principle #35Parameter changes

AI summary

A turnstile having two hub and arm assemblies funnels individuals to different sides or lanes. Machine intelligence allows the turnstile to select which side or lane an individual transits. The turnstile may randomly, pseudo-randomly, or strategically which side or lane an individual transits.
