Single Focus Adjustment Button with Pressure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photo devices with focus adjustment mechanisms require two buttons for zooming operations, leading to a cluttered design, increased costs, and user confusion due to the need to differentiate between zoom in and zoom out buttons.
Innovation Solution
A single focus adjustment button connected to a pressure detection module that outputs signal values based on displacement, allowing the lens assembly to adjust focus intuitively by lengthening or shortening in response to user pressure, eliminating the need for separate zoom buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two focus adjustment buttons are used for zooming operations, then the photo device can perform zoom in and zoom out functions, but the number of function buttons increases and the device complexity increases
Solution Approach 1:
The patent combines two separate focus adjustment buttons (zoom in and zoom out) into a single focus adjustment button. The pressure detection module detects different pressure levels or pressing directions to distinguish between zoom in and zoom out operations, thereby reducing the number of physical buttons while maintaining both zooming functions.
Solution Approach 2:
The single focus adjustment button is designed to perform multiple functions: it can detect different pressing intensities or directions to execute both zoom in and zoom out operations. The pressure detection module enables this multi-functionality by interpreting various pressure patterns from the same button to trigger different zooming actions.
2Adaptability or versatility
If two focus adjustment buttons are disposed side by side, then zooming operations can be performed, but the photo device occupies more space and the layout becomes cluttered
Solution Approach 1:
The patent merges two side-by-side buttons into one consolidated button structure. This reduction in the number of discrete components directly decreases the space required for button arrangement and simplifies the overall device layout, eliminating the clutter associated with multiple adjacent buttons.
3Adaptability or versatility
If two focus adjustment buttons are used, then zooming functions are available, but the user needs to remember which button is for zoom in and which is for zoom out
Solution Approach 1:
The pressure detection module provides immediate feedback by detecting the specific pressing pattern (intensity, direction, or duration) and correspondingly executing the appropriate zooming action. This direct mapping between user input and system response makes the operation intuitive, as the button's physical interaction naturally indicates its function without requiring the user to memorize button assignments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the focus adjustment mechanism, reduces component clutter, and enhances user intuitiveness by allowing focus adjustment with a single button, where the pressing direction corresponds to the lens assembly's lengthening or shortening direction.
Implementation Method 1
a pressure detection module disposed in the photo device in a position corresponding to the focus adjustment button to contact the contact portion, with the pressure detection module being electrically coupled with the lens assembly. When the focus adjustment button is pressed, the pressure detection module can output a signal value according to a displacement value of the focus adjustment button
