Solution Overview

Problem

Existing wearable electronic devices waste energy and duplicate functions when multiple devices are connected to a central device, leading to unnecessary power consumption.

Innovation Solution

A method for a central device to establish communication with multiple wearable electronic devices, determine if they support the same function, and disable redundant services on one device to reduce power consumption by selecting a target device based on device information such as battery level and power consumption speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple wearable electronic devices are connected to the central device simultaneously, then device functionality and service coverage are improved, but power consumption increases and energy is wasted

Engineering Contradiction:
Improveservice coverageVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent merges the functionality of multiple wearable devices by having the central device manage and coordinate services across connected devices. When multiple devices support the same function, the central device selects one as the primary device and disables redundant services on other devices, combining their capabilities into a unified system that maintains service coverage while eliminating duplicate operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The central device acts as a universal coordinator that can manage multiple types of wearable electronic devices with different functions. It provides multi-functionality by handling service configuration, power management, and coordination across diverse device types, allowing the system to adapt to various service scenarios without requiring each individual wearable device to independently manage all functions.

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

2Reliability

If multiple wearable electronic devices with duplicate functions are connected, then service redundancy provides backup and reliability, but device functions are wasted and electrical energy is unnecessarily consumed

Engineering Contradiction:
Improveservice redundancyVSAvoidunnecessary energy consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts the redundant service functions from multiple wearable devices and consolidates them under central device management. The central device identifies which services are duplicated across connected devices and selectively disables them on non-primary devices, removing the harmful energy consumption while preserving the ability to access backup functionality if needed through the central coordination.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system dynamically changes the operational state of services on wearable devices based on the connection status and configuration. When multiple devices are connected, the central device modifies service parameters by disabling redundant services on secondary devices while maintaining them on the primary device, thereby adapting power consumption to actual service needs while preserving reliability through centralized management.

Inventive Principle:
Principle #35Parameter changes

3Speed

If all wearable electronic devices maintain active services, then service availability and response time are improved, but power consumption and energy waste increase

Engineering Contradiction:
Improveservice response timeVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by stationary object

Solution Approach 1:

The central device performs preliminary configuration of services when wearable devices first connect, identifying primary and secondary devices for each function. This advance setup ensures that services are immediately available on the primary device without requiring all devices to maintain active services, reducing energy consumption while preserving fast response times through pre-established service assignments.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method for controlling wearable electronic devices, a central apparatus, and a central device are provided, where the method includes: after establishing communication connections to at least two wearable electronic devices, determining, by the central device, whether the at least two wearable electronic devices support a same function (101); and if the at least two wearable electronic devices support a same function, obtaining device information of the wearable devices supporting the same function, and determining, according to the device information, at least one of the wearable electronic devices that support the same function as a target wearable electronic device (102); and disabling a service that is corresponding to the same function and that is on the target wearable electronic device (103). In this way, a central device is enabled to perform function scheduling and configuration management on multiple wearable electronic devices that all support a same service function, which helps reduce power consumption of the wearable electronic devices.
