Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If position information is continuously transmitted between camera and portable device, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic transmission of position information at predetermined time intervals instead of continuous transmission. The portable device and camera exchange position data at regular intervals, which maintains communication reliability while significantly reducing power consumption compared to continuous transmission modes.
Solution Approach 2:
The patent dynamically adjusts transmission timing based on device states and operating modes. When the camera is in standby mode or the portable device is in power-saving mode, transmission is suspended or delayed. This dynamic adaptation allows the system to maintain reliability when needed while conserving energy during low-activity periods.
2Use of energy by moving object
If position information transmission is controlled based on device states and operating modes, then power efficiency is improved, but device complexity increases
Solution Approach 1:
The patent employs a control unit that handles multiple functions: monitoring device states, determining operating modes, deciding transmission timing, and managing position information exchange. This multi-functional control unit consolidates complexity into a single component that can adapt to various scenarios without requiring separate control mechanisms for each case.
Solution Approach 2:
The patent changes operational parameters (transmission timing, transmission suspension, transmission resumption) based on device states and operating modes. By dynamically adjusting these parameters rather than adding complex hardware, the system achieves power efficiency while keeping the control architecture relatively simple.
3Use of energy by moving object
If position information is transmitted only when needed, then power consumption is reduced, but communication reliability deteriorates
Solution Approach 1:
The patent uses periodic transmission at predetermined intervals to ensure position information is updated regularly without requiring continuous communication. This periodic approach maintains position accuracy for navigation and tracking purposes while allowing the system to enter low-power states between transmissions.
Solution Approach 2:
The patent transmits position information in advance at predetermined intervals before it might be strictly needed. This preliminary transmission ensures that position data is available when required without waiting for specific trigger events, maintaining reliability while enabling power-saving modes during intervals between transmissions.
Data Source
AI summary
An electronic device including a generation unit, a reception unit, a storage unit, and a control unit. The generation unit generates data. The reception unit receives, from an external device, position information related to a position. The storage unit stores the received position information. The control unit determines an elapsed length of time that has passed since the reception unit received the position information. In response to the elapsed length of time being less than a predetermined length of time, the control unit correlates the generated data with the stored position information. In response to the elapsed length of time being greater than or equal to the predetermined length of time, the control unit transmits a request, to the external device, to transmit updated position information, and correlates the generated data with the updated position information.
