Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face challenges in managing power constraints, leading to errors such as device resets and data errors when attempting to establish high data rates, as they exceed the available power limits of computing devices.
Innovation Solution
A wireless communication apparatus and method that identifies a maximum data rate based on the power constraint of a computing device and transmits this information to a second device, ensuring data transmission within the power limits to prevent errors.

Engineering Contradiction Analysis
1Speed
If the wireless communication device attempts to establish high data rates, then the data transmission speed is improved, but power consumption exceeds the available power limits causing device resets and data errors
Solution Approach 1:
The system performs preliminary identification of the maximum data rate based on the power constraint before actual data transmission begins. The wireless communication device determines the maximum data rate that can be supported by the computing device's power budget, and this information is communicated to the base station in advance, allowing the transmission to proceed within safe power limits without causing device resets or data errors
Solution Approach 2:
The system changes the data rate parameter dynamically based on the power constraint. Instead of attempting to maintain a fixed high data rate, the wireless communication device adjusts the data rate parameter to match the maximum sustainable rate determined by the computing device's power budget, thereby achieving optimal transmission speed without exceeding power limits
2Reliability
If the wireless communication device limits data transmission rate to maximum allowed, then power-related errors are prevented, but data transmission speed is reduced
Solution Approach 1:
The system optimizes the data rate parameter to achieve the maximum possible value within the power constraint. By continuously determining and adjusting the maximum data rate based on the power budget, the system achieves the highest reliable transmission speed that maintains communication stability without causing power-related errors, thus balancing reliability and productivity
