Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing security systems require touch-based interaction, which raises hygiene concerns and requires frequent cleaning, and can lead to wear and tear on buttons, potentially compromising PIN security.

Innovation Solution

A premises security system utilizing a control device with processing circuitry that receives signals indicative of hand gestures, correlates them to predetermined commands, and performs actions such as arming or disarming the system, using a radar sensor for gesture detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If touch-based interaction is used for security system control, then ease of operation is improved, but hygiene is worsened and wear on buttons increases

Engineering Contradiction:

Improveease of operationVSAvoidhygiene

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical touch-based keypad interface with a gesture recognition system using cameras and image processing. Users interact with the security system by performing hand gestures in the air rather than physically touching buttons, thereby eliminating contact with the keypad surface and addressing hygiene concerns while maintaining ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary layer between the user and the security system control. Instead of direct contact with the keypad, users perform gestures in the air, and the system uses camera-based gesture recognition as an intermediary to translate these gestures into control commands, thereby eliminating direct contact with the keypad.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If touch-based interaction is used for security system control, then ease of operation is improved, but button wear increases compromising PIN security

Engineering Contradiction:

Improveease of operationVSAvoidPIN security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical button-based input method with gesture-based control. By eliminating physical contact with the keypad, the system prevents wear and tear on buttons that could compromise PIN security, while maintaining ease of operation through intuitive hand gestures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a virtual copy of the control interface in the form of gesture recognition. Instead of using physical buttons that wear down, the system uses captured images of hand gestures as a substitute for physical input, thereby eliminating wear issues while preserving the ease of operation.

Inventive Principle:

Principle #26Copying

3Ease of operation

If touch-based interaction is used for security system control, then ease of operation is improved, but cleaning frequency increases

Engineering Contradiction:

Improveease of operationVSAvoidcleaning time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the physical keypad interface with a gesture-based control system. By eliminating the need to touch the keypad, users no longer need to clean it frequently, thereby reducing the time and effort required for maintenance while maintaining ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The gesture recognition system is self-contained and requires no physical contact with the keypad for operation. The system automatically captures and processes hand gestures through cameras, eliminating the need for user cleaning of the keypad surface and reducing maintenance time.

Inventive Principle:

Principle #25Self-service

AI summary

A control device in a premises security system configured to communicate with a premises device that includes a radar sensor for sensing hand gestures is provided. The control device receives signaling from the premises device indicative of a hand gesture, performs a first correlation of the hand gesture to a predetermined premises security system command, performs a second correlation of a verbal security password, a speaker voice recognition, a presence of the user's phone near the control device, a presence of a registered wearable near the control device, a camera viewing a registered home occupant inside the premises, or biometrics to the predetermined premises security system command, and performs a first action based on the first correlation and second correlation, such as arming or disarming the premises security system.
