Multi-Stage Trigger Button for Video Recording Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing devices face issues with image quality due to device shaking caused by actuating the trigger button, which can result in blurred or unsteady recordings, especially during short video durations, as the button's pre-configured behavior disrupts the continuity of the recording.
Innovation Solution
A multi-stage trigger button mechanism that alters its behavior based on the duration and timing of actuation, allowing for continuous recording or halting based on predefined time periods, minimizing device movement and providing user control without pre-setting modes, and displaying indicia for elapsed recording time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional trigger button is actuated to capture video images, then the recording function is activated, but device shaking occurs causing blurred or unsteady recordings
Solution Approach 1:
The trigger button implements dynamic behavior where the recording function changes based on the duration of button actuation. A first press activates recording, while holding the button beyond a threshold duration continues recording without causing device shaking. This dynamic response adapts the system behavior to the user's interaction intensity, resolving the contradiction between activating recording and preventing shaking-induced blur.
2Adaptability or versatility
If the trigger button behavior is pre-configured for different recording modes, then specific recording functions are available, but device complexity increases
Solution Approach 1:
The trigger button system automatically determines the appropriate recording mode based on the duration of button actuation without requiring user configuration. The system self-adjusts between snapshot mode (brief press) and continuous recording mode (extended hold) based on the interaction itself, eliminating the need for pre-configured modes or additional controls while maintaining versatility.
3Manufacturing precision
If the trigger button actuation duration is extended to avoid shaking, then image quality improves, but loss of time occurs
Solution Approach 1:
The system establishes a predetermined threshold duration that separates snapshot mode from continuous recording mode. By setting this threshold in advance, the system allows users to quickly capture snapshots with brief presses while automatically transitioning to stable continuous recording only when the button is held beyond the threshold, thus minimizing time loss while ensuring image quality when needed.

AI summary
Mechanisms are described for capturing video images using a multi-stage trigger button, where the effect of the trigger button is dependent on how a user interacts with the trigger button, such as during what timeframe the user releases the trigger button. For example, if the user ceases actuating the trigger button during a first time period following actuation, the capture of the video image is halted. If the user ceases actuating the trigger button during a second time period, the capture of the video image is continued. If the user ceases actuating the trigger button during a third time period, the capture of the video image is halted. Thus, for short actuations and long actuations, video images are only recorded while the trigger button is continued to be depressed. For video images in between, the video is continued to be recorded until a second actuation is received from the user.
