Shutter Trigger Multi-Position Control for Rapid Frame Rate Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems lack a convenient and rapid method for selecting different shutter frame rates, which limits the user's ability to adapt to varying shooting conditions and situations.
Innovation Solution
A camera system with a shutter trigger connected to a controller that responds to different positions and forces, allowing for multiple frame rates to be selected through a single shutter trigger button, providing tactile feedback and potentially using a touch panel for actuation, enabling seamless transitions between frame rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional two-state shutter release switch is used, then the structure is simple and reliable, but the user cannot rapidly select different frame rates
Solution Approach 1:
The shutter release button is transformed from a static two-state switch to a dynamic multi-state input device. By detecting different press depths (first threshold for single shot, second threshold for burst mode, third threshold for high-speed mode), the system enables rapid frame rate selection through continuous mechanical input, resolving the contradiction between operational speed and structural simplicity
Solution Approach 2:
The invention changes the parameter of button press depth from a binary state to a multi-level continuous parameter. This allows a single mechanical button to encode multiple frame rate options (1 fps, 3 fps, 5 fps, 10 fps, 20 fps) based on how far the user presses, eliminating the need for separate controls for each mode
2Adaptability or versatility
If multiple frame rates are available, then the camera adapts to varying shooting conditions, but the user interface for selecting them becomes complex
Solution Approach 1:
The shutter release button serves multiple functions: single shot mode, burst mode, and high-speed continuous mode are all activated through the same button interface. This multi-functionality eliminates the need for separate buttons or menu navigation for each frame rate option, maintaining ease of operation while providing versatile shooting capabilities
Solution Approach 2:
The system automatically selects the appropriate frame rate based on the button press depth without requiring manual menu selection. The controller interprets the physical characteristics of the button press (depth, duration) and autonomously determines the shooting mode, making the camera self-adaptive to user intentions
3Adaptability or versatility
If a touch-sensitive surface is used for shutter control, then multiple functions can be provided, but the mechanism for detecting force and position becomes complex
Solution Approach 1:
The invention replaces complex electronic touch-sensitive surfaces with a simple mechanical button system. By using traditional mechanical switches with varying actuation thresholds, the system achieves force and position detection without requiring capacitive sensors, strain gauges, or other sophisticated electronic detection mechanisms
Solution Approach 2:
The mechanical button system inherently provides both position and force information through its physical design. The varying actuation thresholds are built into the mechanical structure itself, eliminating the need for separate electronic sensing systems and reducing overall device complexity

AI summary
A camera has a shutter trigger connected to the body, a controller operably connected to the trigger, and a shutter operably connected to the trigger. The shutter is operable at a plurality of frame rates and the controller is responsive to the shutter trigger in the first condition to operate the shutter at a first frame rate. The controller responsive to the shutter trigger in the second condition to operate the shutter at a different second frame rate.
