Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate devices are used for applying compositions and exposing with light, then each device can be optimized for its specific function, but the overall treatment becomes complex and error-prone
Solution Approach 1:
The patent combines multiple separate treatment devices (application device for compositions and exposure device for light) into a single integrated treatment device. This integration eliminates the need to coordinate multiple separate devices, reducing operational complexity and potential errors while maintaining the specialized functions of each component through modular design elements.
Solution Approach 2:
The treatment device is designed with multi-functionality, serving both as an application device for dispensing compositions and as an exposure device for delivering light therapy. This universal design allows a single device to perform multiple treatment steps that previously required separate specialized equipment.
2Productivity
If multiple devices are used for different treatment steps, then each step can be performed with specialized equipment, but the treatment effort and time increase
Solution Approach 1:
By merging the composition application function and light exposure function into a single integrated device, the treatment process becomes more efficient. The device can deliver both treatments simultaneously or in seamless sequence without the time loss associated with transitioning between separate devices, thereby improving productivity while reducing total treatment time.
3Measurement precision
If treatment is performed with multiple separate devices, then each device can be optimized for its function, but it becomes difficult to treat localized wounds precisely
Solution Approach 1:
The integration of application and exposure functions within a single device ensures precise localization of treatment. The coordinated delivery of compositions and light from the same device position eliminates misalignment issues that arise when using separate devices, enabling accurate treatment of localized wounds while simplifying the coordination required.
4Reliability
If photodynamic disinfection is performed with standard methods, then the process follows established protocols, but complete disinfection is not always achieved
Solution Approach 1:
The integrated device combines photodynamic disinfection with additional treatment modalities, allowing for more comprehensive disinfection protocols. This merger enables sequential or combined application of different treatment approaches (photodynamic therapy, other compositions, adjunctive treatments) through a single device platform, improving disinfection reliability without requiring coordination of multiple separate devices.
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
Enables simple, precise, and effective treatment of wounds by ensuring compositions are applied and exposed accurately, reducing the need for multiple devices and minimizing side effects, while allowing for versatile use with various compositions and treatments.
Implementation Method 1
Photodynamic therapy (PDT) is understood to mean a method for the treatment, inter alia, of tumors and other tissue changes, such as, for example, vessel developments with light in combination with a light-activatable substance, a so-called photosensitizer, and oxygen present in the tissue. For this purpose, such a primary non-toxic sensitizer or one of its metabolic precursors is administered to the patient either systemically or locally, which accumulates selectively in the tumor, or the tissue change due to certain properties of the tumor or the tissue change. After a certain waiting time, the tumor or the tissue change is irradiated with light of suitable wavelength. In this case, toxic substances, above all reactive oxygen species, are produced by photophysical processes, that damage the tumor or tissue change.
Implementation Method 2
The application device comprises at least one application opening for dispensing the compositions from the application device to the tissue section.
