Solution Overview

Problem

Current systems lack effective scheduling restrictions for electronic communications in controlled-environment facilities, such as prisons, which can lead to unregulated interactions between inmates and non-residents, potentially compromising security and order.

Innovation Solution

An exclusion engine is implemented to manage electronic communication requests by utilizing permissive and restrictive lists, determining whether non-residents are allowed to communicate with inmates based on predefined exclusion lists, and allowing personnel to modify these lists as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If no restrictions are placed on electronic communication scheduling, then ease of operation is improved, but facility security deteriorates

Engineering Contradiction:
Improveease of scheduling electronic communicationVSAvoidfacility security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces an exclusion engine as an intermediary system between the communication scheduling request and the facility security requirements. This engine automatically checks exclusion lists (both permissive and restrictive types) to determine whether electronic communications should be permitted, thereby maintaining security without manual intervention while preserving ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If exclusion lists are manually managed, then communication control is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication controlVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The exclusion engine operates autonomously by automatically retrieving and applying exclusion list data from the facility's database system. The system self-manages the communication control function by programmatically checking whether non-residents are on permissive or restrictive lists, eliminating the need for manual list management while reducing operational complexity.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If permissive lists are used to identify allowed non-residents, then communication precision is improved, but loss of time increases

Engineering Contradiction:
Improvecommunication authorization accuracyVSAvoidtime to process communication requests
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-establishing permissive and restrictive exclusion lists that identify authorized and prohibited non-residents before communication requests are made. When a communication request arrives, the exclusion engine simply checks whether the non-resident appears on these pre-prepared lists, enabling rapid authorization decisions with high precision without time-consuming manual verification.

Inventive Principle:
Principle #10Preliminary action

AI summary

An exclusion engine for electronic communications in controlled-environment facilities. In some embodiments, a method may include method may include receiving, at one or more computer systems, a request for an electronic communication between a resident and a non-resident of a controlled-environment facility and determining, via the one or more computer systems, whether an exclusion list adopted by the controlled-environment facility allows the non-resident to communicate with the resident, where the exclusion list is of a type selected from the group consisting of: a permissive list, and a restrictive list. For example, a permissive list may identify one or more non-residents that are allowed to communicate with the resident, and a restrictive list may identify one or more non-residents that are not allowed to communicate with the resident.
