Electronic Device Finger Image Positioning and Dirt Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nail printing devices face challenges in accurately positioning and adjusting the printing target, such as human nails, due to the need for precise finger placement and adjustment, which can be hindered by dirt accumulation on the device's components.
Innovation Solution
An electronic device, including a processor that controls the capture of finger images and photographed images of specific parts, such as the finger stage and mirror, to determine their state by comparing these images with initial comparison images, thereby facilitating accurate positioning and maintenance of the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mirror is installed near the placement unit to assist position adjustment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent uses imaging units to capture images of the placement unit and generates comparison images that copy the visual appearance of the placement surface. These comparison images are displayed on a display unit to help users determine the state of the placement unit without adding physical mirrors or complex optical components to the device structure.
2Measurement precision
If the placement unit is photographed to determine dirt level, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces physical inspection methods with an imaging-based system. Imaging units photograph the placement unit, and the processor analyzes these images to determine dirt levels. This substitutes mechanical or visual inspection with optical imaging and image processing, achieving precise measurement without complex mechanical structures.
Solution Approach 2:
The patent introduces comparison images as an intermediary between the actual placement unit and the user's judgment. The imaging units capture images of the placement unit, these are processed into comparison images that highlight dirt levels, and displayed for user reference. This intermediary system enables accurate dirt level determination without requiring direct physical measurement.
3Measurement precision
If multiple imaging units are used to photograph the placement unit from different directions, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the imaging function into multiple imaging units positioned at different locations. Each imaging unit photographs the placement unit from its specific direction, and the processor integrates these multiple images to comprehensively determine the state of the placement unit. This segmentation of the imaging function enables accurate multi-angle assessment without requiring a single complex imaging system.
