Solution Overview

Problem

In home automation systems, it is difficult for electricians to locate installed products connected to wired or wireless communication networks, such as KNX buses, when they are hidden behind walls or in recessed boxes, especially when multiple products are distributed across a room.

Innovation Solution

A sound localization device is integrated into the product, featuring a transducer element, like a piezoelectric buzzer, that emits an audible signal when an electrical voltage is applied, allowing the product to be located even when not visible, by being connected directly to the network or the electronic card.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the product is installed behind a partition wall or in a recessed box, then the product is hidden and secure, but it becomes difficult for electricians to locate the product during installation and maintenance

Engineering Contradiction:
Improveproduct security and proper installation positioningVSAvoidease of locating product for installation and maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies acoustic signaling (analogous to visual indicators) by integrating a sound localization device that emits audible signals to indicate the product's location. The transducer element converts electrical signals to sound waves, allowing electricians to locate hidden products through acoustic cues rather than visual inspection, resolving the contradiction between hiding the product for security/proper positioning and making it locatable for maintenance.

Principle #32Color changes

2Adaptability or versatility

If multiple products are distributed across a room in different places, then the system coverage is improved, but the difficulty of locating each individual product increases

Engineering Contradiction:
Improvesystem coverage and distributionVSAvoiddifficulty of locating individual products
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The sound localization device enables detection of individually distributed products by emitting distinct acoustic signals from each product location. This allows electricians to identify and locate specific products among multiple distributed units through sound, maintaining system coverage while solving the detection difficulty.

Inventive Principle:
Principle #32Color changes

3Shape

If the product is not visible after installation, then the aesthetic appearance and proper integration into the building structure is improved, but the ability to find and access the product for intervention is reduced

Engineering Contradiction:
Improveaesthetic integration and proper installationVSAvoidease of accessing product for intervention
Core Design Contradiction:
ShapeVSEase of repair

Solution Approach 1:

The acoustic signal emission mechanism provides a non-visual indication method that maintains the product's hidden aesthetic integration while enabling easy location for repair and intervention. The sound localization device allows the product to remain invisible behind walls or surfaces while providing acoustic cues for access.

Inventive Principle:
Principle #32Color changes
