Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair transplanters with a bundle type configuration require multiple driving motors and a complex structure to operate, increasing component costs and device complexity.
Innovation Solution
A hair transplanter design that attaches multiple needle channels to the outer circumference of a rotary body, using a mechanical structure to rotate, eject, and return the needle channels without the need for separate driving motors, reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple needle channels are mounted in a bundle type configuration, then the number of hair transplantation needles increases, but the device complexity and number of driving motors increase
Solution Approach 1:
Multiple needle channels are merged into a single bundle structure where multiple needles are arranged radially around a common core shaft. This allows multiple needle channels to be operated together as one unit, reducing the need for separate driving motors for each needle channel while increasing the total number of needles that can be implanted simultaneously.
Solution Approach 2:
The core shaft serves multiple functions: it acts as the central support structure for radial needle channels, provides the rotation axis for the entire bundle, and serves as the ejection mechanism for all needles simultaneously. This multi-functionality reduces the overall number of components needed in the system.
2Ease of operation
If multiple driving motors are used to operate needle channels independently, then precise control is achieved, but component cost and device complexity increase
Solution Approach 1:
The control system merges multiple needle channel operations into a single control mechanism. One driving motor controls the rotation of the entire needle channel bundle, and one ejection mechanism controls all needles simultaneously, replacing what would otherwise require multiple independent motors and control systems.
Solution Approach 2:
The mechanical structure of the needle channel bundle itself provides the control mechanism. The radial arrangement of needles around the core shaft allows a single rotation to position each needle independently at different angular positions, and a single ejection force is automatically distributed to all needles through the shared core shaft structure.
3Quantity of substance
If needle channels are arranged radially on the outer circumference of a rotary body, then more needle channels can be mounted in the same space, but the structural design becomes more complex
Solution Approach 1:
The needle channels are arranged in a radial configuration around the core shaft, transitioning from a linear or planar arrangement to a three-dimensional radial layout. This allows multiple needles to be positioned at different angular positions around the circumference, effectively increasing the number of needles that can be mounted within the same radial space without significantly increasing the overall device footprint.
Solution Approach 2:
The radial arrangement of needle channels around the cylindrical core shaft creates a spherical or radial distribution pattern. This curved, radial geometry allows for optimal spacing and positioning of multiple needles around the circumference, maximizing the number of needles that can be accommodated while maintaining structural integrity and simplicity.
