Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Intelligent devices without a trigger button face challenges in entering test mode, as existing methods require manual triggering, which is not feasible for devices like intelligent bulbs.

Innovation Solution

The intelligent device periodically scans a Wi-Fi network for a preset SSID, enters a test mode if the SSID is detected, and further verifies if the signal strength meets a threshold to ensure accurate environment detection, thereby automatically entering the test mode without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual triggering method is used to enter test mode, then test mode entry is reliable for devices with trigger buttons, but intelligent devices without trigger buttons cannot enter test mode

Engineering Contradiction:

Improvetest mode entry capabilityVSAvoidmanual triggering requirement

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical trigger button system with an electromagnetic signal-based detection system. The intelligent device uses its Wi-Fi module to scan for and detect a specifically named Wi-Fi network (preset SSID), and upon detection, automatically enters test mode without requiring any physical button press. This substitution enables devices without mechanical interfaces to be tested.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a Wi-Fi network with a preset SSID as an intermediary medium between the tester and the intelligent device. The tester creates a Wi-Fi network with a specific name, and when the intelligent device detects this network name during scanning, it triggers test mode entry. This intermediary enables indirect communication and control without direct physical interaction.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If SSID detection is used to trigger test mode, then devices without trigger buttons can enter test mode, but misjudgment may occur in normal Wi-Fi environments

Engineering Contradiction:

Improvetest mode entry capabilityVSAvoidtest mode entry accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the detection parameter from simple SSID presence to a combination of SSID matching and signal strength threshold. The device not only checks if the preset SSID is detected but also verifies that the received signal strength exceeds a predetermined threshold value. This dual-parameter approach significantly reduces the likelihood of false positive triggering in normal Wi-Fi environments while maintaining reliable test mode entry when intended.

Inventive Principle:
