Dual Wireless Communication Unit for Camera Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often miss shooting opportunities due to the long time it takes to establish a wireless connection for remote shooting functions in digital cameras with wireless communication, as existing technologies prioritize fast data transfer speeds over quick connection establishment.
Innovation Solution
An electronic apparatus with multiple communication units, including a faster but slower-to-connect wireless LAN and a quicker-to-establish Bluetooth connection, allows switching between them automatically to enable seamless remote control and data transfer without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wireless LAN is used for remote shooting communication, then data transfer speed is improved, but connection establishment time increases
Solution Approach 1:
The system performs preliminary action by establishing a Bluetooth connection before wireless LAN connection. The Bluetooth connection is set up in advance to enable immediate remote control operations, while the wireless LAN connection is simultaneously or subsequently established for high-speed data transfer. This preliminary establishment of a functional (though slower) connection ensures that no shooting opportunities are missed during the WLAN setup phase.
Solution Approach 2:
The communication system is segmented into two distinct communication channels: Bluetooth for control commands and WLAN for data transfer. Each communication unit serves a specific function - Bluetooth handles remote control requests while WLAN handles image and video data transfer. This segmentation allows the system to leverage the quick connection establishment of Bluetooth while simultaneously utilizing the high data transfer speed of WLAN, resolving the contradiction between connection speed and data transfer speed.
2Loss of time
If Bluetooth is used for communication, then connection establishment time is reduced, but data transfer speed decreases
Solution Approach 1:
The communication system segments functionality across two protocols: Bluetooth is used for low-bandwidth control commands (shooting requests, parameter changes) where quick connection establishment is critical, while WLAN is used for high-bandwidth data transfer (image files, video streams) where transfer speed is critical. This functional segmentation allows each protocol to operate in its optimal performance range without compromise.
Solution Approach 2:
The electronic apparatus implements multi-functionality by supporting both Bluetooth and WLAN communication units, each serving different but complementary functions. The system can switch between or combine these communication methods based on the specific operational requirements, making the overall communication system universally capable of handling both quick connection scenarios and high-speed data transfer scenarios.

AI summary
An electronic apparatus comprises a first communication unit for wireless communication, a second communication unit having a slower wireless communication speed than the first communication unit, a processing unit carrying out processing based on received requests, and a control unit that controls the communication, wherein, when a prescribed request has been received from an external device via a communication connection established via the second communication unit, the control unit starts connection processing with the external device using the first communication unit, and wherein the processing unit executes processing in accordance with the request received via the second communication unit in a period up until a communication connection is established by the first communication unit, and executes processing in accordance with the request received via the first communication unit after the communication connection has been established by the first communication unit.
