Solution Overview
Problem
Current wireless transmitting/receiving devices lack the capability to input and transmit audio signals from devices like mobile phones and MP3 players, as they do not have audio signal connectors, limiting their functionality to only wireless data transfer.
Innovation Solution
A wireless transmitting/receiving device equipped with a connector, digital signal processor, analog signal processor, and an audio signal connector, allowing it to connect and transmit both digital and audio signals wirelessly, using a switch to determine the signal processor connection based on the connected device's interface or sound output port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless transmitting/receiving devices are designed with only wireless communication capabilities, then the device structure remains simple, but the device cannot input or transmit audio signals from electronic devices like mobile phones and MP3 players
Solution Approach 1:
The wireless transmitting/receiving device is designed with multiple input interfaces including both digital connectors (USB, Bluetooth) and analog audio connectors (3.5mm jack), enabling it to handle various signal types from different electronic devices. This multi-functionality allows a single device to serve both wireless data transfer and audio signal transmission purposes, resolving the contradiction between versatility and structural simplicity.
Solution Approach 2:
The device internally segments different signal processing paths by providing separate digital signal processor and analog signal processor modules. Each processor handles specific signal types through dedicated connectors, allowing the device to maintain clear functional separation while achieving multi-purpose capability. This segmentation enables the device to accommodate multiple signal types without creating a tangled, complex structure.
2Adaptability or versatility
If the device includes both digital connector and audio signal connector with corresponding signal processors, then it can connect to various electronic devices, but the device structure becomes more complex
Solution Approach 1:
A switch module is introduced as an intermediary component that selectively connects either the digital signal processor or the analog signal processor to the wireless emitter based on the type of connected device. This mediator simplifies the internal circuit structure by preventing both signal processors from being permanently connected to all interfaces, thereby reducing circuit complexity while maintaining full device compatibility with various electronic devices.
Solution Approach 2:
The device employs dynamic connection routing where the switch module automatically or manually configures the signal path based on the connected device type. This dynamic adaptability allows the internal circuit structure to reconfigure itself, maintaining optimal simplicity for the current usage scenario while preserving compatibility with different device types across various scenarios.
