Network ID Comparison for Access Point Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital camera technologies face challenges in establishing efficient wireless communication with external devices, particularly in determining whether an external device is operating as an access point, which affects data transmission and reception capabilities.
Innovation Solution
A communication apparatus is designed with a connection unit to receive a network ID and connect to a network formed by an access point, a communication unit for establishing communication with external devices, and a processing unit to compare network IDs with device IDs to determine if the external device is operating as an access point, enabling secure and efficient data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a digital camera uses a simple access point function to form a network, then ease of operation is improved, but reliability deteriorates due to inability to determine if external device is the access point
Solution Approach 1:
The communication apparatus compares the network ID received during connection establishment with the stored device ID to determine whether the external device is the intended access point. This feedback mechanism provides confirmation of correct connection, resolving the reliability issue while maintaining ease of operation through automatic verification.
Solution Approach 2:
The patent replaces manual verification methods with automatic network ID comparison. Instead of requiring users to manually verify connection status, the system automatically substitutes mechanical/physical verification with electronic ID comparison, maintaining ease of operation while improving reliability.
2Reliability
If network ID comparison is performed to determine access point status, then reliability is improved, but device complexity increases
Solution Approach 1:
The communication unit performs multiple functions: it both establishes communication with external devices and compares network IDs to verify access point status. By making the communication unit multi-functional, the patent avoids adding separate verification hardware, thus improving reliability without significantly increasing device complexity.
Solution Approach 2:
The patent merges the network verification function with the existing communication unit. Instead of creating a separate verification system, the communication unit is enhanced to perform both communication establishment and ID comparison, reducing overall system complexity while improving reliability.
Data Source
AI summary
A communication apparatus receives a network ID from an access point, connects to a network formed by the access point, establishes communication with an external device via the connected network, allows data communication, receives a device ID from the external device, compares the network ID of the connected network with the received device ID, and determines whether the external device is operating as the access point based on a result of the comparison.
