Streetlight Wire Ring Barrier for Internal Component Theft Deterrence

Solution Overview

Problem

Streetlights with copper or valuable electrical wires are susceptible to theft, and existing systems lack effective deterrents to prevent the theft of internal components.

Innovation Solution

A streetlight system featuring a stack of rings made of durable materials that encircle the electrical wires, which are assembled from segments that interlock circumferentially and can be keyed axially, along with other deterrent methods such as expanding foam plugs and sensors that trigger alarms or deploy deterrent materials upon tampering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If electrical wires are made of valuable materials like copper to provide power to light fixtures, then the electrical conductivity and power transmission are improved, but the wires become susceptible to theft

Engineering Contradiction:

Improvepower transmissionVSAvoidtheft susceptibility

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The protective barrier is divided into multiple discrete rings that can be individually installed around the electrical wires. Each ring acts as an independent segment of the overall protective system, allowing for modular installation and maintenance while collectively providing comprehensive protection against theft.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A protective barrier consisting of rings acts as an intermediary structure between the valuable electrical wires and potential thieves. This intermediate layer physically impedes access to the wires without interfering with their electrical function, thereby protecting the wires while maintaining power transmission.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a protective barrier is installed around electrical wires to deter theft, then theft prevention is improved, but the device complexity and installation difficulty increase

Engineering Contradiction:

Improvetheft preventionVSAvoidinstallation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The protective barrier is divided into multiple discrete rings that can be individually installed around the electrical wires. Each ring acts as an independent segment of the overall protective system, allowing for modular installation and maintenance while collectively providing comprehensive protection against theft.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rings are designed to be nested around the electrical wires in a concentric arrangement. Each ring fits around the wires and potentially around other rings, creating a layered protective structure that maximizes protection while minimizing the space required for installation.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Object-affected harmful factors

If multiple stacked rings are assembled around electrical wires to impede theft, then access difficulty to wires is improved, but the assembly time and labor requirements increase

Engineering Contradiction:

Improveaccess difficultyVSAvoidassembly time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The protective barrier is divided into multiple discrete rings that can be individually installed around the electrical wires. Each ring acts as an independent segment of the overall protective system, allowing for modular installation and maintenance while collectively providing comprehensive protection against theft.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rings can be pre-assembled in groups or stacks before being installed around the wires. This preliminary preparation reduces the time required during actual installation, as pre-assembled units can be quickly positioned and secured around the electrical wires without requiring complex on-site assembly procedures.

Inventive Principle:

Principle #10Preliminary action

AI summary

A streetlight apparatus and method involves use of an anti-theft material for deterring theft of electrical wiring from a streetlight. The anti-theft material includes a stack of rings encircling the electrical wiring in the chamber of the base of the streetlight, where each ring of the stack of rings may include a plurality of ring segments that are each individually insertable through an access opening of the base of the streetlight and positioned around the electrical wiring.
