Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless data transmission methods experience prolonged wait times when transmitting data to multiple target machines, as they rely on a single communication method that is not optimized for directivity and speed.
Innovation Solution
A transmission and reception apparatus utilizing a first communication method (WiFi) for data transmission and a second communication method (WiGig) that is higher in directivity and faster, allowing for simultaneous data transmission to multiple target machines with storage confirmation information received through the first method after successful transmission via the second method.

Engineering Contradiction Analysis
1Loss of time
If data is transmitted to multiple target machines using a single communication method, then communication simplicity is maintained, but transmission wait time is prolonged
Solution Approach 1:
The patent segments the communication process into two distinct phases: a fast transmission phase using the second communication method (WiGig) for actual data transfer, and a confirmation phase using the first communication method (WiFi) for storage verification. This segmentation allows the system to leverage the speed advantage of WiGig while maintaining the reliability of WiFi for confirmation, thereby reducing overall transmission wait time without requiring completely new communication infrastructure.
Solution Approach 2:
The patent performs preliminary data transmission using the fast second communication method before the storage confirmation process is complete. By initiating the transmission ahead of time and allowing confirmation to proceed in parallel, the system eliminates the sequential waiting period where the transmitter must wait for storage verification before starting the next transmission, thus reducing total transmission wait time.
2Speed
If the first communication method is used for both data transmission and storage confirmation, then communication protocol simplicity is maintained, but transmission speed is reduced
Solution Approach 1:
The patent applies local quality by assigning different communication methods to different functional requirements: the second communication method (WiGig) is used specifically for the data transmission function where speed is critical, while the first communication method (WiFi) is used for the confirmation function where reliability and compatibility are more important. This localized optimization allows the system to achieve high transmission speed without requiring the entire communication system to operate at the higher speed level.
Solution Approach 2:
The transmission apparatus is designed with multi-functionality by incorporating both first and second communication units, allowing it to adaptively select appropriate communication methods based on the specific task requirements. This multi-functional design enables the system to use the fast second communication method for transmission while falling back to the reliable first communication method for confirmation, achieving both speed and reliability without sacrificing either function.
3Productivity
If storage confirmation is waited for before transmitting to the next machine, then data accuracy is ensured, but productivity is reduced
Solution Approach 1:
The patent ensures continuity of useful action by allowing the transmission process to proceed continuously without interruption for storage confirmation. The second communication unit transmits data to the next target machine immediately after the previous transmission is initiated, while the first communication unit handles confirmation in parallel. This continuous transmission approach maintains high productivity while the separate confirmation channel ensures data accuracy is still verified, eliminating the stop-and-wait pattern of traditional sequential confirmation.
Solution Approach 2:
The patent introduces an intermediary communication structure where the first communication method acts as a mediator for storage confirmation while the second communication method handles the main data transmission. This intermediary arrangement allows the two communication methods to operate semi-independently, enabling the fast transmission to proceed without being blocked by the slower confirmation process, thus improving productivity while maintaining reliability through the mediating confirmation channel.

AI summary
A transmission and reception apparatus includes a first communication unit that performs communication by a first communication method, a second communication unit that performs communication by a second communication method which is higher in directivity than the first communication method and is faster than the first communication method, and a control unit that performs control such that storage confirmation information, which indicates whether data has been stored in a storage device provided in a first target machine without an error, is received through the first communication unit after the data is transmitted to the first target machine through the second communication unit, data transmission confirmation is received from the first target machine, and the data is transmitted to a second target machine through the second communication unit.
