Wireless HID Signal Aggregation Reducing Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless Human Interface Devices (HIDs) face inefficiencies in data transmission due to high power consumption and data packet loss, primarily because they repeatedly send redundant overhead data, which increases energy usage and reduces transmission efficiency.
Innovation Solution
A system that combines multiple sense data and overhead area data into a single data packet, reducing the length of packets and minimizing redundant overhead data transmission, thereby improving data exchange efficiency and conserving energy.

Engineering Contradiction Analysis
1Use of energy by moving object
If wireless HID transmits data using standard Bluetooth packets with overhead area, then data transmission is achieved, but power consumption increases and transmission efficiency decreases due to redundant overhead data
Solution Approach 1:
The patent combines multiple sense data packets into a single aggregated packet that shares a common overhead area. Instead of transmitting separate Bluetooth packets for each sense data point (each with its own overhead), the system merges multiple data points and transmits them together with one overhead section, thereby reducing redundant transmission and lowering power consumption while improving transmission efficiency.
2Loss of information
If multiple separate data packets are transmitted for each sense data, then complete data information is transmitted, but packet length increases and transmission time increases due to repeated overhead areas
Solution Approach 1:
The patent aggregates multiple sense data packets into a single packet structure that contains all necessary data information along with a shared overhead area. This merging approach maintains complete data transmission while significantly reducing the total transmission time by eliminating repeated overhead sections that would otherwise be present in multiple separate packets.
3Reliability
If standard Bluetooth packet structure is used with access code and header for each transmission, then reliable communication is achieved, but energy consumption increases due to repeated overhead areas
Solution Approach 1:
The patent maintains communication reliability by preserving the essential Bluetooth packet structure (access code, header) but applies it once to an aggregated packet containing multiple sense data points. This single overhead section serves multiple data points, thereby maintaining reliable communication while reducing electrical energy consumption compared to transmitting separate packets with individual overhead sections for each data point.

AI summary
A signal sending device, a signal receiving device, and a signal sending and receiving system and method are presented. The devices and system combine a plurality of sense data into a data packet to transmit the data packet. Through the method, the data packet is processed, received, and sent under a transmission mechanism based on independent data packets. Therefore, the plurality of sense data and overhead data are combined into a data packet, and thus the redundant overhead data is reduced, so as to reduce the time spent on sending actual data to a transmission channel, thus improving the efficiency of data exchange and saving electrical energy.
