Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for remote control systems face challenges in power-saving and responsiveness due to the need for frequent connection maintenance and limited multi-partner control capabilities.
Innovation Solution
A wireless communication apparatus and remote control system that utilize power-saving near field communication, allowing multi-addressed communication requests to be sent before pairing, enabling efficient control command transmission and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-to-one communication connection is established by pairing, then reliable communication is achieved, but power consumption increases due to frequent connection maintenance
Solution Approach 1:
The patent applies preliminary action by establishing communication connection requests before pairing is completed. The remote control apparatus sends control commands in the advertising phase before formal connection establishment, allowing control functionality to work without maintaining a persistent paired connection, thus reducing power consumption while preserving reliability for actual control operations
Solution Approach 2:
The patent implements periodic action by allowing the remote control apparatus to enter sleep mode between control operations instead of maintaining continuous connection. The system periodically wakes to send control commands via advertising packets and then returns to sleep, eliminating the need for frequent connection maintenance while keeping the system responsive
2Use of energy by moving object
If connection is cut off to sleep state for power saving, then power consumption is reduced, but reconnection time increases and responsiveness degrades
Solution Approach 1:
The patent uses preliminary action by pre-establishing the advertising packet structure containing control commands before sleep mode. The remote control apparatus prepares control data in advance within advertising packets, allowing the control target apparatus to process commands immediately upon receiving advertisements without waiting for reconnection, thus eliminating reconnection delay while maintaining power savings
3Reliability
If one-to-one pairing connection is required, then communication security is maintained, but the number of remote control partners is limited to one
Solution Approach 1:
The patent applies universality by enabling a single remote control apparatus to control multiple control target apparatuses through the advertising phase. By embedding control commands in advertising packets that can be received by multiple devices, the system allows one remote to universally control multiple targets without requiring separate paired connections for each device, thus expanding multi-partner capability while maintaining security through command authentication

AI summary
In a wireless communication apparatus that performs power-saving near field communication by transmission-side wireless communication units 21A, 21B on a remote side and reception-side wireless communication units 25A, 25B on a control target apparatus 30A, 30B side, the transmission-side wireless communication unit 21A, 21B has a MCU 23A, 23B that performs multi-address transmission via a BLE antenna 22A, 22B, and the reception-side wireless communication unit 25A, 25B has a communication IC 27A, 27B. The transmission-side MCU 23A, 23B generates a communication connection request including, in a transmission packet, specific company identification information and communication data having device information corresponding to the control target apparatus and command data for controlling such a device, and the reception-side communication IC 27A, 27B supplies a specific control command to a device MCU 31A, 31B of the control target apparatus when identification information from a remote matches identification information already stored inside.
