Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger devices for cameras require high pressing forces due to fixed gear structures, making them inconvenient to use and unable to adjust to a user's customary force, affecting the shooting experience.
Innovation Solution
A trigger device with a resilient structure, including a connecting piece and toggle piece, allows for adjustable elastic deformation and rotation, enabling customizable pressing forces for half-pressed and full-pressed shutter operations, enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plurality of gear structures are combined for deceleration, then the trigger device can provide high touch to prevent accidental shooting, but the pressing force becomes fixed and requires very high force when the shutter button is far from the trigger device, making it inconvenient to use
Solution Approach 1:
The patent replaces the fixed gear deceleration mechanism with a resilient structure that allows dynamic adjustment of the trigger force. The resilient structure can be adjusted to different stiffness levels, enabling the trigger force to adapt to different distances between the shutter button and trigger device, thus maintaining ease of operation while preventing accidental shooting.
Solution Approach 2:
The patent changes the physical parameter of the trigger mechanism from a fixed gear ratio to an adjustable resilient structure with variable stiffness. This allows the pressing force to be adjusted according to the distance between the shutter button and trigger device, resolving the contradiction between reliability and ease of operation.
2Reliability
If a plurality of gear structures are combined for deceleration, then the trigger device can provide high touch through the shutter release button, but the pressing force cannot be adjusted to a customary force, affecting the user experience
Solution Approach 1:
The resilient structure provides dynamic adjustability of the trigger force, allowing users to adjust the pressing force to their customary force preference. This replaces the fixed gear mechanism with an adjustable system that maintains reliable shutter release control while adapting to user preferences.
Solution Approach 2:
The adjustable resilient structure makes the trigger device universal by allowing it to adapt to different user preferences and different camera types. The same trigger device can be adjusted to work with various shutter button distances and user force preferences, enhancing its versatility.
3Device complexity
If a fixed gear mechanism is used, then the trigger device structure is relatively simple, but it cannot accommodate different camera types and user preferences
Solution Approach 1:
The patent changes the trigger mechanism from a fixed gear structure to an adjustable resilient structure. While this slightly increases structural complexity, it provides the ability to adjust the pressing force to accommodate different camera types and user preferences, achieving versatility with minimal added complexity.
