Solution Overview

Problem

Users are hesitant to install electrically autonomous home automation devices powered by solar energy due to uncertainty about sufficient sunlight at the installation location, which can lead to reduced energy production and device reliability.

Innovation Solution

A method for testing compatibility between the energy needs of an electrically autonomous home automation device and a predetermined location, involving data collection on position, solar radiation, and shading masks to estimate energy balance and confidence index, using a mobile or fixed terminal to determine if the device can operate correctly throughout the year.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a self-powered home automation device is installed in a location with potential shading obstacles, then the device can be installed without grid connection, but the photovoltaic module may not receive sufficient sunlight to guarantee proper operation throughout the year

Engineering Contradiction:
Improveinstallation easeVSAvoidoperation reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent performs preliminary shading analysis and solar radiation assessment at the installation location before the device is installed. By calculating the shading mask from surrounding obstacles and evaluating the expected energy production throughout the year, the system determines in advance whether the location is suitable for reliable operation, preventing installation in inadequate locations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses the device's own photovoltaic module characteristics and location data to self-assess its future performance. By inputting the device type and installation location, the system automatically calculates whether the expected solar energy input will meet the device's power requirements, enabling self-verification of installation suitability.

Inventive Principle:
Principle #25Self-service

2Reliability

If a compatibility testing method is implemented to assess solar radiation and energy balance, then installation reliability can be validated, but the complexity of the installation process increases

Engineering Contradiction:
