Existing wound healing technologies lack a non-invasive and non-toxic approach that effectively combines optical and magnetic stimulation to enhance tissue regeneration and wound healing, particularly in chronic wounds where the natural electric signal for tissue regeneration is lost.
Innovation Solution
A combined optical and magnetic stimulation (OMS) wound therapy device that includes a light source for generating an optical field, an electric circuit, a coil for generating a magnetic field, and a magnetic field shield to protect the electric circuit and light source from the coil's magnetic field, allowing for a compact and efficient design that homogenizes the magnetic field distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coil is used to generate a magnetic field for wound therapy, then magnetic stimulation effect is improved, but the magnetic field interferes with the electric circuit and light source operation
Solution Approach 1:
A magnetic field shield is introduced as an intermediary component between the coil and the electric circuit/light source. The shield selectively blocks magnetic field lines from reaching sensitive components while allowing the magnetic field to pass through to the wound site, thus resolving the interference problem without compromising therapeutic effectiveness
2Object-affected harmful factors
If the magnetic field shield is added to protect the electric circuit, then magnetic field interference is reduced, but the device structure becomes more complex
Solution Approach 1:
The magnetic field shield is implemented as a thin, flexible shield that can be integrated into the existing device structure. This minimizes the increase in device complexity while effectively protecting the electric circuit and light source from magnetic field interference
3Volume of moving object
If the light source and coil are placed close together for compact design, then device size is reduced, but the magnetic field interference with the electric circuit increases
Solution Approach 1:
The magnetic field shield serves as a protective intermediary that enables the light source and coil to be positioned in close proximity for compact device design. The shield blocks magnetic field lines from reaching the electric circuit while allowing the magnetic field to reach the wound, thus permitting compact configuration without increasing interference
