Color-Coded Voice Wake-Up Control for Multi-Device Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart home voice control systems require extensive pre-recording and storage of commands, leading to high workload and cost, and suffer from misoperation and interference when multiple devices of the same type are used simultaneously, resulting in poor user experience.
Innovation Solution
A smart voice wake-up control method using a main control board that sets and matches command light colors with corresponding voice commands, allowing users to intuitively recognize and execute control commands through a color-coded system, featuring a device with a microprocessor, voice pickup, relay, and indicator light capable of emitting multiple colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-recording and storage of all first-level commands is implemented through the voice recognition module, then voice control functionality is achieved, but the workload and cost increase significantly
Solution Approach 1:
The patent applies universality by using a single color-coded wake-up command system that can control multiple different types of electrical appliances. Instead of requiring separate pre-recorded commands for each appliance type, the system uses a universal color-based wake-up approach where the indicator light color indicates which appliance will be controlled, making the voice recognition module more versatile while reducing its workload
Solution Approach 2:
The patent changes the parameter of voice command recognition from text-based semantic understanding to color-based signal recognition. The voice recognition module only needs to recognize wake-up commands with specific color keywords (red, green, blue, yellow) rather than storing and matching numerous appliance-specific commands, significantly reducing complexity while maintaining functionality
2Adaptability or versatility
If multiple identical socket modules are installed in the same space, then more electrical products can be controlled, but misoperation and interference occur when multiple devices are used simultaneously
Solution Approach 1:
The patent applies local quality by assigning different colors to different socket modules or different control modes. Each socket module or control instance has a unique color identifier displayed on its indicator light, allowing users to distinguish between multiple devices. This localized color differentiation ensures that voice commands are executed by the correct device, preventing misoperation and interference while enabling control of multiple electrical products
Solution Approach 2:
The patent uses color changes as a visual identification mechanism to solve the problem of distinguishing multiple devices. The indicator light emits different colors (red, green, blue, yellow) to represent different wake-up commands or device identities. When multiple socket modules are installed, users can identify which device corresponds to which color, ensuring accurate command execution and eliminating interference between simultaneous operations

AI summary
The invention discloses a smart voice wake-up control method and a control device thereof. The smart voice wake-up control device includes a casing, a main control board, a control switch, a voice pickup, a relay, an output terminal, an input terminal and a work indicator capable of emitting multiple colors of light, the main control board is respectively connected with the control switch, the voice pickup, the relay and the work indicator, and the relay is respectively connected with the output terminal and the input terminal. When multiple smart voice wake-up control devices are used simultaneously, the user can change the light color of the work indicator by controlling the control switch to distinguish different colors of voice wake-up commands, i.e., use the light color of the work indicator to show the color wake-up voice, so that the user can get the wake-up commands intuitively and quickly for controlling.
