Solution Overview

Problem

Conventional charging devices are limited in their ability to simultaneously charge both wireless handy cleaners and robot cleaners, and they lack the functionality to transmit and receive control instructions and information effectively, restricting their operational efficiency and user convenience.

Innovation Solution

A charging device system that includes a first charger for the handy cleaner and a second charger for the robot cleaner, both equipped with transceivers for wireless communication, a processor for managing charging and actuation signals, and a communication line to connect the chargers, enabling simultaneous charging and information exchange, as well as providing actuation signals and device information to users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional charging devices charge both handy cleaners and robot cleaners simultaneously, then charging capability is provided, but the devices lack functionality to transmit and receive control instructions and information effectively

Engineering Contradiction:
Improvecharging capabilityVSAvoidcontrol instructions and information transmission
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The charging device is designed to perform multiple functions: it charges both handy cleaners and robot cleaners simultaneously while also serving as a communication hub that transmits and receives control instructions and information between the cleaners and the user's terminal device, eliminating the need for separate charging and communication functions

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

2Device complexity

If the charging device only provides charging function, then device complexity is reduced, but operational efficiency and user convenience are restricted

Engineering Contradiction:
Improvecharging function onlyVSAvoidoperational efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The charging device integrates charging functionality with communication and control capabilities, allowing it to simultaneously charge multiple cleaners and exchange information with them and the user's terminal device, thereby improving operational efficiency without significantly increasing complexity

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

Solution Approach 2:

The charging device establishes bidirectional communication with the cleaners through transceivers, enabling real-time feedback on charging status, position information, and operational data, which enhances user convenience and operational efficiency by providing timely information exchange

Inventive Principle:
Principle #23Feedback

3Loss of information

If the charging device equips transceivers for wireless communication and communication lines to connect chargers, then information exchange capability is improved, but device complexity increases

Engineering Contradiction:
Improveinformation exchange capabilityVSAvoidtransceivers and communication lines
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The charging device acts as an intermediary between the cleaners and the user's terminal device, using transceivers and communication lines to facilitate information exchange. This centralized mediation approach improves information exchange capability while managing complexity by consolidating communication infrastructure in one location rather than requiring complex point-to-point connections between all devices

Inventive Principle:
Principle #24Intermediary (Mediator)
