Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Underwater cameras face operational difficulties due to waterproof requirements limiting button sensitivity, combined with challenges like cold fingers, poor visibility, and buoyancy issues, making manual video recording cumbersome and often resulting in unwanted footage.
Innovation Solution
An underwater digital video camera with an auto-record system that starts and stops recording based on depth triggers, using a depth gauge for current depth data and allowing user-adjustable settings, including start and stop delays, to automate video capture without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual recording operation is used, then user can control recording start/stop, but operation becomes difficult due to waterproof housing and environmental factors
Solution Approach 1:
The camera system performs recording operations automatically based on depth sensing, eliminating the need for manual user intervention. The depth gauge continuously monitors depth and triggers recording automatically when predetermined depth thresholds are reached, allowing the system to serve itself without requiring user operation in the challenging underwater environment.
Solution Approach 2:
The patent replaces manual mechanical button pressing with an electronic depth-triggered automation system. The depth gauge electronically detects depth and automatically controls the recording function through electronic signals, substituting the mechanical operation of pressing buttons in the waterproof housing with an electronic sensing and control system.
2Loss of information
If recording starts before entering water, then user can prepare for recording, but video includes unwanted scenes of movement and hand close to lens
Solution Approach 1:
The system performs preliminary setup by storing multiple predetermined depth thresholds in memory before the diving activity begins. These depth thresholds are configured in advance to correspond to the specific diving location and activity, so that when the dive occurs, the camera can automatically start recording at the appropriate depth without requiring preliminary manual operation or causing unwanted pre-dive footage.
3Extent of automation
If fixed trigger depths are used, then automation is simplified, but adaptability to different diving preferences and types is limited
Solution Approach 1:
The system incorporates dynamic configurability where the depth thresholds and recording parameters can be adjusted and customized by the user based on their specific diving preferences, location, and activity type. This allows the automation system to adapt its behavior dynamically rather than using fixed predetermined settings, maintaining both automation and versatility.

AI summary
The invention relates to an underwater digital video camera having an auto record system for automatically starting and stopping video recording at predetermined depths. The camera receives a current depth from a depth gauge and holds a sequence of recent currents depths and auto record settings such as a start trigger depth and a stop trigger depth, wherein the auto record system is adapted to, after the start/stop trigger depth is arrived at or passed for increasing/decreasing depths, start/stop video recording.
