Solution Overview
Problem
Existing wound closure devices face challenges of high cost, long production time, and difficulty in mass production due to the need for customization based on the shape and size of each wound.
Innovation Solution
A connecting unit comprising a cofferdam baffle, closure device, and fixator with adjustable and locking mechanisms, allowing for the formation of a structurally stable window by connecting multiple units to accommodate various wound sizes and shapes, including a ratchet and ratchet wheel mechanism, and limiting connecting rods for stabilization, along with sealing films to create a negative pressure chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wound closure devices are customized according to the shape and size of each wound, then the device can fit the specific wound requirements, but the production cost increases, production time lengthens, and mass production becomes difficult
Solution Approach 1:
The device is divided into multiple standardized connecting units that can be independently manufactured and then assembled together. Each unit contains a cofferdam baffle, closure device, and fixator that can be mass-produced using standardized processes, while the overall device configuration can be customized by combining different numbers and arrangements of these modular units to match various wound shapes and sizes.
Solution Approach 2:
The connecting units are designed with universal interfaces and standardized components that can be used across different device configurations. The first and second connecting parts with corresponding mating structures can be universally applied to join multiple units together in various arrangements, allowing a single standardized component design to serve multiple wound treatment scenarios.
2Adaptability or versatility
If wound closure devices are customized for each specific wound, then the device can provide precise fit, but the production cost increases
Solution Approach 1:
By segmenting the device into standardized connecting units, each unit can be manufactured using consistent processes and materials, achieving economies of scale. The modular design allows precise fitting to be achieved through configuration rather than custom manufacturing, significantly reducing production costs while maintaining adaptability.
3Strength
If the window is made with a fixed shaped structure to bear pulling force, then the structural strength is sufficient, but the device cannot adapt to different wound shapes and sizes
Solution Approach 1:
The window structure transitions from a fixed rigid shape to a dynamic configurable structure. Multiple connecting units can be assembled and disconnected to create windows of various shapes and sizes while maintaining the structural integrity needed to bear pulling forces. The standardized connecting parts ensure consistent mechanical strength across different configurations.
4Productivity
If standardized connecting units are used for mass production, then production efficiency increases, but the device complexity increases due to multiple components
Solution Approach 1:
Each connecting unit integrates multiple functions into a single modular component: the cofferdam baffle for wound isolation, the closure device for wound approximation, and the fixator for skin attachment are combined with standardized connecting parts. This merging reduces the overall system complexity by eliminating the need for separate manufacturing and assembly of individual components, while maintaining mass production efficiency.
