Wireless Pairing Without Pre-assigned IDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication systems for devices like mice and keyboards require pre-pairing with dongles, which increases production costs due to the need for printed circuit boards to store ID information and the labor involved in printing IDs.
Innovation Solution
A wireless communication method that eliminates the need for pre-pairing IDs by transmitting IDs on different power levels across multiple frequency points, receiving ACKs, and identifying the device with the highest response to establish communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-pairing IDs are used for wireless communication, then communication reliability is improved, but manufacturing cost and complexity increase due to memory storage requirements and ID printing steps
Solution Approach 1:
The patent extracts the ID storage function from the PCB hardware and relocates it to the communication protocol layer. Instead of storing IDs in memory on the PCB, the system uses temporary ID assignment and exchange during the pairing process, eliminating the need for persistent storage hardware and associated complexity.
Solution Approach 2:
The patent replaces the mechanical/physical ID printing and storage system with a software-based ID assignment mechanism. Instead of physically printing IDs on devices and storing them in memory, the system dynamically assigns and exchanges IDs during the wireless pairing process, substituting physical infrastructure with communication protocol mechanisms.
2Measurement precision
If pre-pairing IDs are implemented, then device identification accuracy is improved, but production labor costs increase due to ID printing requirements
Solution Approach 1:
The patent implements self-service by enabling devices to automatically generate and exchange their own identification information during the pairing process. Instead of requiring manual ID printing and storage, each device independently assigns its ID and facilitates the pairing exchange, eliminating labor-intensive production steps while maintaining accurate device identification.
3Reliability
If multiple power levels and frequency points are used for ID transmission, then pairing reliability is improved, but communication time increases
Solution Approach 1:
The patent applies preliminary action by performing ID transmission and pairing procedures in advance during the initial connection establishment phase. The system pre-exchanges IDs and establishes pairing information before actual data communication begins, so that when data transmission starts, the pairing is already complete and no additional time is required for pairing operations.

AI summary
A wireless communication method without pairing IDs in advance, comprises: transmitting, at a first power, a first ID within a first pipe; searching for a second ID on at least one frequency point, wherein the second ID matches the first ID; if the second ID is not found within the first pipe, respectively transmitting, at least at a second power and a third power, at least two matching-code requests within a public pipe on public frequency points; receiving ACKs responding to each of the matching-code requests from different devices; summing numbers of the received ACKs from each device; comparing the summed numbers of the received ACKs from the different devices to get a maximum number; switching from a public pipe to a third pipe of a device that sent the maximum number of ACKs; transmitting a matching-code package to the device that sent the maximum number of ACKs.
