Solution Overview

Problem

Existing fenestration systems lack a universally applicable sensor system that can detect tampering or damage to windows, doors, and vents without requiring additional hardware and can monitor the real-time status of these openings.

Innovation Solution

Incorporating an electrically-conductive gasket made of materials like ethylene propylene diene monomer rubber or conductive foam between rigid components of fenestration systems, which acts as a pressure transducer by measuring resistance changes to detect disturbances and communicate with a control system for alarm generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate vibration sensors are installed for windows, doors, and vents, then detection capability for breaking is improved, but device complexity and installation requirements increase

Engineering Contradiction:
Improvedetection capabilityVSAvoidsensor system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The gasket is designed to serve dual functions: providing the sealing function necessary for fenestration systems and acting as a universal sensor for detecting tampering, breaking, and status changes across all fenestration components (windows, doors, vents) through its electrical resistance properties

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The sensor functionality is merged into the existing gasket component by making it electrically conductive, eliminating the need for separate sensor hardware and integrating detection capabilities directly into the sealing element already present in the system

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If traditional point sensors are used, then specific location monitoring is achieved, but coverage area and tamper detection capability are limited

Engineering Contradiction:
Improvedetection accuracyVSAvoiduniversal applicability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The conductive gasket provides universal monitoring coverage across the entire perimeter of any fenestration opening (windows, doors, vents) while maintaining the ability to detect specific localized tampering events through changes in electrical resistance at different segments of the gasket

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The gasket can be monitored at multiple segments along its length, allowing localized detection of tampering events at specific positions while maintaining overall system-wide coverage and universal applicability across different fenestration types

Inventive Principle:
Principle #1Segmentation

3Reliability

If after-market sensor devices are retrofitted, then detection capability is added, but additional tooling and preparation requirements increase

Engineering Contradiction:
Improvesecurity monitoringVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The sensor function is combined with the gasket that is already installed as part of the fenestration system, eliminating the need for additional retrofitted devices and reducing installation requirements to simply ensuring the gasket material is electrically conductive

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The gasket serves itself by providing both sealing and sensing functions, eliminating the need for separate sensor installation and reducing dependency on additional tooling or preparation beyond what is already required for gasket installation

Inventive Principle:
Principle #25Self-service
