Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous video recording is performed to capture all events, then complete footage is obtained, but memory usage increases and editing time increases
Solution Approach 1:
The system performs preliminary actions by continuously capturing video footage in advance of the triggering event. The recording apparatus captures pictorial information continuously for a predetermined period before and after the trigger event occurs, ensuring that relevant footage is already captured and stored when the event happens, eliminating the need for post-event editing to capture the moment itself
Solution Approach 2:
The system segments the continuous video stream into discrete clips based on triggering events. Instead of handling one large continuous video file, the system divides the footage into multiple smaller clips centered around trigger events, each with a predetermined time window. This segmentation makes the footage easier to manage, edit, and share while reducing overall processing time
2Ease of operation
If manual video capture is used, then selective recording is possible, but operation complexity increases and time consumption increases
Solution Approach 1:
The system implements self-service by using sensors to automatically detect and trigger recording events without requiring manual user input. The sensor detects conditions such as motion, GPS location changes, or other parameters, and automatically activates the recording apparatus to capture relevant moments. This eliminates the need for users to manually monitor and control recording, significantly reducing operation complexity and time consumption
Solution Approach 2:
The system uses feedback from sensors to control the recording process. Sensor data continuously monitors the environment and provides feedback to the processing unit, which then triggers the recording apparatus when predetermined conditions are met. This closed-loop feedback mechanism ensures selective and automatic capture of relevant events without requiring continuous manual intervention
3Reliability
If long video sequences are recorded, then comprehensive coverage is achieved, but difficulty in locating critical moments increases
Solution Approach 1:
The system segments long video sequences into smaller, event-centered clips based on triggering events. Each clip is delimited by a predetermined time window around the trigger event, making critical moments easily locatable. Users can quickly identify and access specific moments without searching through extensive continuous footage, as each clip is already organized around significant events
Solution Approach 2:
The sensor acts as an intermediary between the environment and the recording apparatus. Instead of manually searching through video to find critical moments, the sensor continuously monitors conditions and automatically identifies when events of interest occur. This intermediary function simplifies the detection process by pre-identifying significant moments before they need to be reviewed
