Solution Overview

Problem

Cradles for wireless audio devices lack a wireless communication module, preventing them from transmitting or receiving data directly with electronic devices, and existing data communication methods are inefficient.

Innovation Solution

Implementing a first wireless communication device with a power management module for electrical connection to a cradle, a communication module for wireless communication, and a processor to manage data transmission and reception, enabling high-speed power line communication (HPLC) between the cradle and a second wireless communication device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cradle is designed to house wireless communication devices for charging, then the cradle can provide power supply and storage functions, but the cradle cannot perform wireless data communication or firmware update operations

Engineering Contradiction:
Improvedata communication capabilityVSAvoidcradle structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses the wireless communication device itself as an intermediary to enable data communication between the cradle and external electronic devices. The wireless communication device acts as a relay, receiving data from external devices via Bluetooth and forwarding it to the cradle through power line communication, thus eliminating the need for a wireless communication module in the cradle.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent makes the wireless communication device serve multiple functions: it not only provides wireless audio output but also acts as a communication bridge for data transmission and firmware updates. By utilizing the existing communication capabilities of the wireless communication device, the system achieves multi-functionality without adding dedicated communication hardware to the cradle.

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

2Productivity

If data is transmitted from a wireless communication device to the cradle using traditional methods, then data communication can be established, but the data transmission speed is slow and inefficient

Engineering Contradiction:
Improvedata transmission speedVSAvoidfirmware update time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces traditional wireless communication protocols (like Bluetooth) with power line communication for data transmission between the wireless communication device and cradle. Power line communication offers significantly higher data transmission speeds, enabling efficient firmware updates and large data transfers without the time constraints of wireless protocols.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the cradle is equipped with a wireless communication module to enable direct data communication, then data transmission speed improves, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvedata communication efficiencyVSAvoidcradle manufacturing
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent enables the wireless communication device to serve itself by using its own communication capabilities to facilitate data transmission to the cradle. The device leverages its existing Bluetooth module and processor to act as a communication gateway, eliminating the need for the cradle to have dedicated wireless communication hardware, thus simplifying manufacturing.

Inventive Principle:
Principle #25Self-service
