Thimble Bandage Cup Shape for Body Tips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat bandages poorly fit curvilinear body parts, leading to binding, puckering, and inadequate protection of wounds on body tips like fingers and toes, as they fail to securely adhere due to shape mismatch and adhesive limitations.
Innovation Solution
A bandage design featuring a pliable Sleeve with a hingedly-attached flap that can be folded over to secure the bandage in place, using adhesive, hook-and-loop fastening, or other methods, and made from elastomeric materials like polyvinyl chloride or polyurethane to conform to body tips, with an absorbent inner surface for fluid management and medicament application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat bandage is used to cover a wound on a curvilinear body part, then the bandage can be attached to most sections of the body, but it binds, puckers, and bunches, failing to fit well especially on body tips
Solution Approach 1:
The bandage is formed into a three-dimensional cup-shaped structure that conforms to the curvilinear geometry of body tips. This curved configuration allows the bandage to adapt to the natural shape of fingers, toes, and other protruding body parts, eliminating binding and puckering while maintaining secure attachment.
Solution Approach 2:
The invention transitions from a two-dimensional flat bandage to a three-dimensional cup-shaped structure. This dimensional change enables the bandage to wrap around and conform to the contours of body tips, providing better fit and security without the defects of flat bandages.
2Reliability
If adhesive is used to fasten the bandage, then the bandage can be secured to the skin, but adhesive limitations cause the bandage to slip off body tips
Solution Approach 1:
The cup-shaped configuration with its curved surfaces provides better mechanical interlocking with the skin contour, supplementing adhesive bonding. The geometry itself contributes to adhesion by distributing forces evenly and preventing concentration at single points, reducing the likelihood of adhesive failure.
Solution Approach 2:
The bandage utilizes a flexible, conformable structure that adapts to the skin surface, enhancing adhesive contact area and distribution. This flexibility allows the adhesive to maintain effective bonding under various conditions while the cup shape provides structural support.
3Adaptability or versatility
If elastomeric materials are used to improve fit on curvilinear body portions, then the bandage conforms better, but it still suffers from binding and puckering due to shape mismatch
Solution Approach 1:
The cup-shaped structure inherently matches the curvilinear geometry of body tips, eliminating the shape mismatch problem. This pre-formed three-dimensional configuration works synergistically with elastomeric materials to provide conformability without binding or puckering.
Solution Approach 2:
The invention combines elastomeric materials with the cup-shaped structural configuration to achieve both conformability and comfort. The material properties and geometric form work together to eliminate the harmful effects of binding and puckering while maintaining excellent fit.
4Area of stationary object
If multiple elongate shapes like H-shape are used to wrap around body tips, then there are multiple portions to cover tricky spots, but it continues to suffer from binding and puckering
Solution Approach 1:
The cup-shaped structure provides three-dimensional coverage that envelops the body tip, achieving comprehensive coverage without the binding and puckering associated with multiple flat elongate portions. The continuous curved surface maintains uniform contact with the skin.
Solution Approach 2:
By transitioning from multiple two-dimensional elongate portions to a single three-dimensional cup-shaped structure, the invention achieves equivalent or superior coverage while eliminating the defects of the flat multi-portion design.
