Solution Overview
Problem
Existing data transmission methods between communication devices are difficult to control and inefficient, particularly when short-distance wireless communication connections are not established, leading to challenges in relaying data through relay devices.
Innovation Solution
A relay device with a short-distance wireless communicator and processor that establishes connections, transmits information about connectable devices, receives data relay requests, and controls data transmission between communication devices, storing data if connections are not established and transmitting once connections are made.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct short-distance wireless communication is used between two communication devices, then data transmission can be performed directly, but communication devices are difficult to control and pairing is required before transmission
Solution Approach 1:
A relay device is introduced as an intermediary between the first communication device and the second communication device. The relay device manages connections and facilitates data transmission, eliminating the need for direct pairing between the two communication devices. The processor receives a data relay request from the first communication device and controls the short distance wireless communicator to transmit data to the second communication device through the relay device.
2Productivity
If data transmission is attempted when wireless connection is not established, then transmission can be initiated, but transmission fails and data loss occurs
Solution Approach 1:
The relay device performs preliminary actions by establishing wireless connections with communication devices before data transmission is initiated. The processor determines whether the wireless communication connection is established between the second communication device and the relay device before transmitting data. If the connection is not established, the data is stored in the relay device until the connection is available, preventing data loss and ensuring reliable transmission.
3Reliability
If the relay device stores data when connection is not established, then data loss is prevented, but storage space is consumed and transmission is delayed
Solution Approach 1:
The relay device dynamically manages data storage and transmission based on the current connection status. The processor continuously monitors whether the wireless communication connection is established and automatically transmits stored data when the connection becomes available. This dynamic approach ensures that data is transmitted as soon as possible while maintaining reliability, minimizing unnecessary storage time and associated delays.
