Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wound healing devices using electrical stimulation lack ease of use and adaptability to varying wound sizes, and often do not provide adequate mechanical support or direct application methods.
Innovation Solution
A wound healing electrode set comprising a bandage or plaster with detachable, adjustable electrically active zones that can be easily applied to the body, providing mechanical support and allowing for direct electrical treatment, with the option to adapt size to fit different wounds or body parts using elastic or one-time stretchable materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bandage or plaster with detachable electrically active zones is used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent combines the bandage or plaster with electrically active zones into a single integrated unit. The detachable electrodes are merged with the bandage structure, allowing the entire assembly to be applied as one piece to the body, thereby improving ease of operation while managing complexity through functional integration.
Solution Approach 2:
The bandage serves multiple functions: it provides mechanical support to the wound area, positions the electrically active zones correctly, and acts as a delivery mechanism for electrical stimulation. This multi-functionality improves ease of operation by eliminating the need for separate application steps.
2Adaptability or versatility
If electrically active zones are made detachable and adjustable, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The electrically active zones are divided into detachable segments or modules that can be independently positioned and adjusted. This segmentation allows the zones to be adapted to different wound sizes and shapes while using standardized manufacturing processes, thereby managing precision requirements.
Solution Approach 2:
The electrically active zones are designed to be dynamically adjustable rather than fixed. The detachable configuration allows users to modify the position, number, and arrangement of electrodes according to specific wound characteristics, improving adaptability without requiring high manufacturing precision for each possible configuration.
3Strength
If a bandage with electrically active zones is used, then mechanical support is improved, but device complexity increases
Solution Approach 1:
The mechanical support function and electrical stimulation function are merged into a single bandage device. The bandage material itself provides the mechanical support structure, while the electrically active zones are integrated into this structure, eliminating the need for separate support mechanisms.
Solution Approach 2:
The bandage performs dual functions: providing mechanical support/compression to the wound area and delivering electrical stimulation through the active zones. This multi-functionality improves mechanical support capability while managing complexity through functional integration rather than adding separate systems.
