Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If standard electrode systems are used, then the device structure is simple, but the electrodes cannot be shaped to closely follow the contours of the wound
Solution Approach 1:
The electrode system is divided into multiple individual electrodes arranged in an array, where each electrode can be independently controlled. This segmentation allows the electrodes to be configured to match various wound shapes and sizes by selecting and connecting appropriate electrodes from the array, thereby achieving contoured electrode placement without requiring custom-shaped electrodes for each wound.
Solution Approach 2:
The electrode system employs dynamic reconfiguration capability through switching devices that can selectively connect individual electrodes in the array to form composite electrodes. This dynamic adjustment allows the electrode configuration to adapt to different wound geometries and healing stages, enabling the electrodes to closely follow wound contours while using a standardized array structure.
2Adaptability or versatility
If uniform electrical signal application is used, then the system operation is simple, but the treatment cannot be tailored to different tissue types or healing stages
Solution Approach 1:
The system applies different electrical signal characteristics to different regions of the wound by selectively activating specific electrodes in the array. Each electrode or group of electrodes can receive customized signal parameters (amplitude, frequency, pulse duration) tailored to the local tissue type and healing stage, enabling localized treatment optimization without requiring a completely different system for each condition.
Solution Approach 2:
The electrical signal application is made dynamic through controller-based adjustment of signal parameters and electrode configuration. The system can adaptively modify treatment parameters in real-time based on wound assessment, allowing the same system to provide customized treatment for different tissue types and healing stages by changing electrode connections and signal characteristics rather than requiring multiple fixed systems.
3Reliability
If electrodes are placed on either side of the wound boundary, then optimal wound-healing electrical field is created, but achieving suitably shaped electrodes is not feasible with standard systems
Solution Approach 1:
Rather than manufacturing custom-shaped electrodes, the system segments the electrode function into multiple small, standardized electrodes in an array. These individual electrodes can be easily manufactured using standard fabrication techniques, and their collective arrangement and selective connection create the effective shaped electrode configuration needed to place electrodes on either side of the wound boundary and create optimal healing fields.
Solution Approach 2:
The system creates the functional equivalent of custom-shaped electrodes by selectively activating and connecting standard electrodes in the array to form composite electrodes that copy the desired shape and positioning. This approach achieves the therapeutic benefit of custom-shaped electrodes placed at wound boundaries without the manufacturing complexity, using software-controlled electrode selection and connection from a standardized array.

AI summary
A wound healing system comprising an array of electrodes incorporated in a device for applying an electrical signal to a wound. The electrodes are configurable to form at least one composite electrode and the electrical signal is applied to the wound via the composite electrode(s). The system preferably includes means for determining the state of the wound, the electrode composition of the composite electrode(s) depending on the determined state of the wound. Advantageously, the electrode composition of the composite electrode(s) is adjustable in response to changes in the determined state of the wound.
