Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If image capturing is performed at intervals of a predetermined time, then image capturing can be performed automatically without user intervention, but image capturing may fail to capture moments the user wants to record
Solution Approach 1:
The system uses image capturing history information as feedback to dynamically adjust the threshold value. By analyzing whether images were captured in the past under similar conditions, the system learns and adapts its decision-making, improving the reliability of automatic capture while maintaining automation.
Solution Approach 2:
The threshold value, which determines whether to capture an image, is dynamically changed based on image capturing history. This parameter adjustment allows the system to optimize capture decisions over time, balancing automation with capture accuracy by adapting to actual usage patterns.
2Reliability
If the image capturing interval is shortened to avoid missing moments, then capture frequency increases, but power consumption becomes large and available time decreases
Solution Approach 1:
The image capturing interval is made dynamic rather than fixed. The system adjusts the capture interval based on image capturing history and evaluated results, shortening intervals when capture accuracy is prioritized and lengthening them when power conservation is needed, thus optimizing the balance between reliability and energy consumption.
Solution Approach 2:
The capture interval parameter is dynamically adjusted based on historical capture data and evaluation results. This allows the system to optimize power consumption by extending intervals when high accuracy is not critical, while still maintaining the ability to capture important moments when needed.
3Productivity
If automatic image capturing frequency is set high to ensure even distribution, then more images are captured in the first half, but battery or card capacity becomes insufficient in the second half
Solution Approach 1:
The system incorporates feedback from image capturing history and remaining capacity information to adjust capture frequency. By monitoring how many images have been captured and estimating remaining battery or card capacity, the system dynamically modifies its capturing strategy to ensure sustainable operation throughout the entire usage period.
Solution Approach 2:
The image capturing frequency is made dynamic and adjustable based on real-time conditions. Rather than maintaining a fixed high frequency, the system adapts the capture rate according to remaining capacity and historical patterns, allowing high productivity when resources are abundant while conserving resources when capacity is limited.
4Use of energy by moving object
If automatic image capturing frequency is set low to conserve resources, then power consumption decreases, but the number of captured images becomes short
Solution Approach 1:
The capture frequency parameter is dynamically adjusted based on image capturing history and evaluation results. This allows the system to achieve low average power consumption while maintaining high productivity when conditions warrant capture, optimizing the trade-off between energy efficiency and image quantity.
Solution Approach 2:
The system employs periodic evaluation of capture history and conditions to determine when to perform image capturing. This periodic decision-making allows the system to maintain low power consumption during intervals while still capturing images at appropriate moments, achieving a balance between energy efficiency and productivity.
