Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair planting apparatuses face difficulties in accurately positioning a base material due to deviations in the alignment direction of mesh holes, leading to potential defects in hair planting operations.
Innovation Solution
A hair planting apparatus equipped with a mounting portion, hair planting unit, transport mechanism, imaging unit, tilt detection unit, and correction mechanism to ensure precise alignment of the base material by detecting and correcting the orientation of mesh holes using an imaging unit and correction mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the base material is mounted without orientation correction, then the mounting process is simple and fast, but the alignment direction of mesh holes may deviate from the specified direction causing positioning difficulties and defective hair planting
Solution Approach 1:
The imaging unit captures images of the base material before hair planting to detect the alignment direction of mesh holes. The correction mechanism adjusts the orientation of the base material on the mounting portion based on detected alignment deviations, ensuring proper orientation before the hair planting process begins. This preliminary detection and correction action prevents positioning errors and defective hair planting.
2Measurement precision
If manual positioning of the base material is used, then the device structure is simple, but it is difficult to achieve precise alignment when mesh hole alignment direction deviates
Solution Approach 1:
The imaging unit uses optical imaging to capture images of the base material and detect the alignment direction of mesh holes, replacing manual visual inspection. The correction control unit processes the captured images to determine orientation deviations and automatically controls the correction mechanism to adjust the base material orientation, replacing manual positioning operations with automated image-based detection and correction.
3Manufacturing precision
If no orientation correction is performed, then the processing time is short, but positioning accuracy deteriorates leading to defective hair planting
Solution Approach 1:
The system performs alignment detection and correction before the hair planting process begins. The imaging unit captures images of the base material on the mounting portion, the correction control unit determines orientation deviations, and the correction mechanism adjusts the base material orientation in advance. This preliminary correction ensures proper positioning for subsequent hair planting operations.
Solution Approach 2:
The imaging unit provides feedback information about the actual alignment direction of mesh holes on the base material. The correction control unit processes this feedback to determine the degree of orientation deviation and automatically controls the correction mechanism to adjust the base material orientation, creating a closed-loop feedback system that ensures accurate positioning.
