Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple USB wireless transceivers are used to support multiple wireless devices, then the number of connected devices increases, but the USB interface resources are exhausted and device compatibility problems increase
Solution Approach 1:
Multiple USB wireless transceiver functions are merged into a single transceiver device. The patent implements a one-to-many communication architecture where one USB wireless transceiver can simultaneously manage multiple wireless peripherals (keyboard, mouse, headset, camera) by integrating multiple communication channels and protocols within a single device, eliminating the need for multiple separate transceivers and USB interfaces.
Solution Approach 2:
The USB wireless transceiver is designed with multi-functionality to support various types of wireless peripherals simultaneously. It implements universal communication protocols and multiple communication channels that can adapt to different device types (audio, data, control), allowing a single transceiver to replace multiple specialized transceivers and expand the scope of application.
2Reliability
If traditional 2.4G wireless technology is used for each device, then wireless performance is achieved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent implements periodic communication cycles where the USB wireless transceiver and wireless peripherals exchange data in scheduled time slots rather than continuously. The system uses periodic polling and data transmission mechanisms, allowing devices to enter low-power states between communication cycles, thereby reducing overall power consumption while maintaining reliable wireless performance.
3Quantity of substance
If multiple traditional wireless devices are used simultaneously, then device functionality increases, but interference between devices occurs and transmission stability decreases
Solution Approach 1:
The patent segments the wireless communication spectrum into multiple independent channels within the 2.4G band. Each wireless peripheral is assigned to a specific communication channel, and the USB wireless transceiver manages these channels separately. This channel segmentation prevents interference between different device types (keyboard, mouse, headset) while allowing simultaneous operation, maintaining transmission stability even with multiple devices connected.
4Ease of operation
If traditional wireless technology is used, then basic wireless communication is achieved, but anti-interference capability is weak and transmission performance becomes unstable
Solution Approach 1:
The patent dynamically changes communication parameters such as frequency, data rate, and modulation scheme based on channel conditions and interference levels. The USB wireless transceiver monitors the wireless environment and adjusts transmission parameters in real-time to optimize performance and resist interference, enhancing anti-interference capability while maintaining ease of wireless communication operation.
