Conduction Cord Segmentation for Curved Pad Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conduction cords for low-frequency treatment devices struggle to securely attach electrode pads to sites with large curvatures, such as the wrist, due to limited flexibility and ease of attachment, often resulting in the pad ends lifting up.
Innovation Solution
A conduction cord with independently arranged connection terminal portions coupled by an elastic coupling portion, which forms a flexible group, and an electrode pad with a gel layer for enhanced adhesion, allowing for reliable and intimate attachment to curved surfaces without movement restriction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an easily bendable material is used for the conduction cord, then the flexibility is improved, but the response capability to steep curved surfaces remains limited
Solution Approach 1:
The connection terminal portions are divided into multiple independent sections (first, second, third connection terminal portions) that can move independently relative to each other. This segmentation allows each section to adapt to different parts of curved surfaces while maintaining overall connectivity, resolving the contradiction between flexibility and response capability to steep curves.
Solution Approach 2:
The connection terminal portions are designed to be movable relative to each other, creating a dynamic structure that can adjust its configuration in real-time. This dynamic capability enables the conduction cord to respond to varying curvature requirements of different treatment sites, overcoming the limitation of static flexible materials.
2Adaptability or versatility
If the conductive section is divided into three or more portions, then the connection terminal portions can be arranged independently, but the connecting portion becomes large making attachment to curved surfaces difficult
Solution Approach 1:
The connection terminal portions are segmented into multiple independent units that can be arranged in different configurations. This segmentation allows the connecting portion to maintain a compact size while still providing independent arrangement capability, enabling attachment to curved surfaces without excessive complexity.
Solution Approach 2:
The movable connection terminal portions create a dynamic connecting structure that can adjust its effective size and configuration. This dynamic adjustment reduces the apparent complexity of the connecting portion while maintaining the ability to independently arrange terminals for various curved surface applications.
3Area of stationary object
If the adhesive pad is attached to a treatment site having large curvature, then the treatment coverage is improved, but the ends of the adhesive pad lift up reducing intimate attachment
Solution Approach 1:
The movable connection terminal portions create a dynamic connection system that can adjust to the curvature of treatment sites. This dynamic adaptation prevents the pad ends from lifting up by accommodating the geometric constraints of curved surfaces, thereby maintaining intimate attachment while achieving comprehensive treatment coverage.
Solution Approach 2:
The connection terminal portions can change their spatial arrangement and configuration parameters to match the curvature of different treatment sites. This parameter adjustment capability ensures that the adhesive pad maintains intimate contact with curved surfaces while covering the required treatment area, preventing edge lifting.
