Solution Overview
Problem
Camera systems face challenges in detecting and connecting with devices operating in different wireless modes, particularly due to limitations in power efficiency and the need for manual credential entry with limited input interfaces, which hinders seamless communication and operation.
Innovation Solution
The camera system automatically switches between access point, ad hoc, and station modes to detect and connect with devices, and uses another device to obtain and transfer wireless credentials wirelessly, optimizing power usage and simplifying credential entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera operates in access point mode to enable wireless communication with multiple devices, then connectivity and communication capability are improved, but power consumption increases
Solution Approach 1:
The camera dynamically switches between access point mode and station mode based on operational requirements. The system monitors connectivity needs and automatically transitions to the most energy-efficient mode while maintaining necessary communication capabilities, thus resolving the contradiction between adaptability and power consumption.
Solution Approach 2:
The camera changes its wireless communication parameters by switching between different operational modes (access point, station, ad hoc). This parameter change allows the system to optimize power consumption by selecting station mode when possible, while maintaining adaptability to switch to access point mode when multiple device connectivity is required.
2Reliability
If the camera uses manual credential entry for wireless connection, then connection security is improved, but ease of operation deteriorates due to limited input interface
Solution Approach 1:
The camera implements self-service credential acquisition by automatically detecting available wireless networks and obtaining credentials through wireless transfer from other devices. This eliminates the need for manual credential entry while maintaining secure connections, thus improving ease of operation without compromising connection security.
Solution Approach 2:
The system uses an intermediary wireless credential transfer mechanism where credentials are automatically exchanged between devices through wireless communication. This intermediary process replaces manual entry, maintaining security through encrypted credential transfer while significantly improving ease of operation.
3Difficulty of detecting and measuring
If the camera automatically switches between communication modes to detect devices, then device detection capability is improved, but device complexity increases
Solution Approach 1:
The camera implements feedback-based mode switching where the system continuously monitors detection results and automatically adjusts communication modes based on detected device responses. This feedback mechanism simplifies the overall system complexity by using simple conditional logic rather than complex manual mode management, while improving device detection capability.
Solution Approach 2:
The camera performs self-service communication mode management by automatically selecting and switching between access point, station, and ad hoc modes based on detected device types and connection requirements. This self-service approach improves device detection capability while managing complexity through automated decision-making algorithms.
4Use of energy by moving object
If the camera operates in station mode for power efficiency, then power consumption is reduced, but connectivity flexibility deteriorates as it can only connect to a single device
Solution Approach 1:
The camera dynamically switches between station mode and access point mode based on connection requirements. When single-device connection is sufficient, the system operates in power-efficient station mode. When multi-device connectivity is needed, it automatically transitions to access point mode, thus dynamically balancing power consumption and connection flexibility.
Solution Approach 2:
The camera changes its operational parameters by switching communication modes in response to detected connection needs. This parameter change allows the system to optimize power consumption through station mode while maintaining adaptability to switch to access point mode for enhanced connection flexibility when required.
