Solution Overview

Problem

Existing electrical wiring devices are difficult for homeowners to replace, as it often requires hiring a professional electrician or poses safety risks when attempted DIY, especially with the increasing variety of outlet types in homes.

Innovation Solution

Modular electrical wiring device assemblies that include a faceplate module with embedded sensors and a wiring device module, allowing for easy integration and control of electrical devices, including USB outlets, with a smooth outer surface for cleaning and featuring capacitive or time-of-flight sensors for enhanced functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrical wiring devices are designed as single integrated units, then reliability and electrical connection stability are improved, but ease of repair and replacement deteriorate

Engineering Contradiction:
Improveelectrical connection stabilityVSAvoidreplacement difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The electrical wiring device is divided into separate modules: a faceplate module containing the outlet apertures and a mounting module containing the electrical connections. This segmentation allows the faceplate to be replaced independently without disturbing the electrical wiring, improving ease of repair while maintaining reliable electrical connections through the modular interface.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple outlet types are integrated into a single device, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveoutlet type varietyVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The faceplate module is designed as a universal platform that can accommodate multiple outlet types (standard electrical outlets, USB outlets, etc.) through standardized aperture configurations. This allows a single base module to support various outlet functionalities without increasing the core structural complexity, as the versatility is achieved through configurable faceplate designs rather than complex internal mechanisms.

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

3Ease of operation

If sensors are embedded in the faceplate module, then ease of operation is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvesensor control functionalityVSAvoidsensor embedding precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The sensor assembly is integrated into the faceplate module as a separate functional unit rather than being embedded directly into the wall structure. This segmentation allows sensors to be positioned and calibrated during faceplate assembly using standard tolerances, reducing manufacturing precision requirements compared to direct wall embedding, while still enabling touch-sensitive and motion-detecting operations.

Inventive Principle:
Principle #1Segmentation
