Segmented Abdominal Closure Element With Radial Slits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abdominal closures in bandages and orthotics are inflexible and uncomfortable due to their fixed width, causing them to dig into the body during movements like bending or sitting, leading to discomfort and poor fit.
Innovation Solution
A flexible closure element comprising two elastic cover layers with a sheet-type stabilizing element having slots between them, providing a secure hold while allowing for flexibility and comfort during body movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If abdominal closures have a certain width to ensure secure hold, then the holding strength is improved, but the flexibility and wearing comfort deteriorate
Solution Approach 1:
The closure element is divided into multiple functional zones: rigid central regions with hook-and-loop fastening for secure holding, and flexible edge regions with radial slits that allow bending and adaptation. This segmentation enables different parts of the same closure element to serve different functions - the center provides strength while the edges provide flexibility.
Solution Approach 2:
Different regions of the closure element are given different mechanical properties. The central region maintains rigidity for secure fastening, while the peripheral regions incorporate radial slits to enhance flexibility. This local differentiation of material properties resolves the contradiction between needing strength in some areas and flexibility in others.
2Stability of the object's composition
If abdominal closures have a fixed width for secure hold, then the stability is improved, but the comfort during body movements deteriorates
Solution Approach 1:
The closure element transitions from a static, fixed-structure design to a dynamic one where the peripheral regions can change shape during body movements. The radial slits enable the edges to expand and contract dynamically, allowing the closure to adapt to changing body contours while maintaining overall structural integrity.
Solution Approach 2:
By segmenting the closure element into rigid central portions and flexible peripheral portions with radial slits, the design maintains structural stability in the center while allowing movement accommodation at the edges, thereby improving wearing comfort during body movements.
3Strength
If abdominal closures press into the body for secure hold, then the holding strength is improved, but the harmful effects on the body increase
Solution Approach 1:
The peripheral regions of the closure element are designed with radial slits creating a flexible, adaptable structure that can conform to body contours without exerting excessive localized pressure. This flexible edge design reduces the harmful pressing effect on the body while maintaining secure fastening through the rigid central region.

AI summary
A flexible closure element for a closure of a medical or orthopedic product or sports product includes a first and second elastic cover layer and a sheet-type stabilizing element therebetween. The sheet-type stabilizing element is slotted over a least half of a length of the stabilizing element on at least one of two longitudinally running edges.
