Solution Overview

Problem

In correctional facilities, inmates lose the ability to use electronic devices during charging due to the need to relinquish them for recharging, and returning charged devices creates logistical challenges.

Innovation Solution

A charging system utilizing existing facility wiring, solar panels, and energy collectors to provide power to inmates, allowing devices to be charged in their possession, with safety features to prevent tampering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If inmates relinquish electronic devices for recharging, then devices can be charged, but inmates lose the ability to use the devices during charging

Engineering Contradiction:
Improvedevice charging capabilityVSAvoiddevice usability during charging
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system separates the charging function from the device itself by providing dedicated charging stations and ports throughout the facility. Inmates can charge their devices at these distributed locations without surrendering the devices, thus maintaining usability while ensuring reliable charging capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The charging system allows inmates to independently charge their own devices at designated stations without staff intervention. The devices remain in inmate possession throughout the charging process, enabling self-service charging while maintaining device accessibility and usability.

Inventive Principle:
Principle #25Self-service

2Reliability

If staff collect electronic devices for charging, then devices can be recharged, but logistical hardship increases for device return

Engineering Contradiction:
Improvedevice charging capabilityVSAvoidlogistical complexity of device management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts the charging function from the device management process. Instead of staff collecting and returning devices, inmates charge their devices at distributed charging stations throughout the facility. This eliminates the logistical complexity of device collection, tracking, and return while ensuring reliable charging capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Dedicated charging stations and ports serve as intermediaries between power sources and inmate devices. These fixed infrastructure elements handle the charging process, eliminating the need for staff to physically manage device collection and return, thus reducing logistical complexity while maintaining charging reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)
