Solution Overview

Problem

Current wireless keyboards and mice require separate button presses and software downloads to switch hosts synchronously, which is inconvenient for users.

Innovation Solution

A wireless keyboard and mouse combo using hardware synchronization, where a switching switch on either the keyboard or mouse triggers both devices to switch hosts, utilizing transceiver chips and Bluetooth technology for linked host switching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless keyboard and mouse use separate switching mechanisms, then each device can independently switch hosts, but the user must press buttons on both devices to switch hosts synchronously

Engineering Contradiction:

Improvehost switching operationVSAvoidswitching mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the switching mechanisms of the wireless keyboard and wireless mouse by introducing a switching controller that receives switching signals from either device and transmits host switching commands to both devices simultaneously. This allows synchronized host switching with a single button press on either the keyboard or mouse, resolving the contradiction between ease of operation and device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The switching controller acts as an intermediary between the wireless keyboard and wireless mouse. When a user presses a switching button on either device, the switching controller receives the signal and coordinates the host switching for both devices, enabling synchronized operation without requiring users to manually switch both devices separately.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If software is downloaded to enable synchronized host switching, then the keyboard and mouse can switch hosts linkedly, but the process becomes inconvenient and requires additional steps

Engineering Contradiction:

Improvehost switching convenienceVSAvoidsetup process

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The switching controller enables the wireless keyboard and mouse to automatically coordinate their host switching without requiring external software intervention. The system self-manages the synchronization by having the switching controller transmit commands to both devices based on signals from either device, eliminating the need for users to download and configure additional software.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the software-based switching synchronization mechanism with a hardware-based solution using a switching controller and switching buttons. This hardware implementation provides more direct and convenient control, allowing users to switch hosts by simply pressing a button on either the keyboard or mouse without needing to install or configure software.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If a switching controller is added to enable linked switching, then synchronized host switching is achieved, but the device complexity increases

Engineering Contradiction:

Improvehost switching capabilityVSAvoidsystem configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The switching controller is designed with multi-functionality, serving as both a signal receiver from either the keyboard or mouse and a command transmitter to both devices. This universal component enables synchronized host switching, multi-device coordination, and flexible operation modes without requiring multiple separate components, thereby managing complexity while enhancing adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)
