Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
UWB communication systems face inefficiencies in data transmission and reception times, particularly in contactless payment systems, leading to prolonged processing times compared to other communication technologies like NFC.
Innovation Solution
Implementing a method and device that utilize out-of-band (OOB) connections and applet pre-selection to determine the location of a second electronic device, enabling efficient UWB communication by reducing the number of data exchanges required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional UWB communication is used for contactless payment, then communication reliability is maintained, but data transmission and reception times are prolonged
Solution Approach 1:
The patent applies preliminary action by determining the location of the second electronic device via OOB connection before initiating UWB communication. The controller selects an applet based on the determined location in advance, so that when UWB communication starts, the applet is already ready for immediate data exchange, reducing overall transmission time and improving service processing efficiency
Solution Approach 2:
The patent uses an intermediary approach by introducing OOB connection as a mediator between the first electronic device and the second electronic device. This OOB connection serves as a preliminary channel to exchange location information and establish communication parameters before the main UWB data transmission, thereby optimizing the overall communication process and reducing time loss
2Productivity
If UWB communication is implemented with location determination, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a system where the first electronic device can perform multiple functions using existing components: location determination via OOB connection, applet selection based on location, and UWB communication. This multi-functional approach eliminates the need for separate dedicated hardware for each function, thereby improving communication efficiency without significantly increasing device complexity
Solution Approach 2:
The patent implements self-service by enabling the first electronic device to autonomously determine the location of the second electronic device via OOB connection and automatically select the appropriate applet based on that location. This autonomous operation reduces the need for manual configuration and complex external control systems, maintaining device simplicity while enhancing communication efficiency
