Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthotic systems are often poorly adapted, expensive, and restrictive in the activities they support, making it difficult for individuals with partial or complete hand function loss to perform daily and recreational tasks comfortably and effectively.
Innovation Solution
A cuff-based orthotic system with a modular design, featuring a lower shell and a fixation element that can be combined to form a sleeve around the limb, utilizing magnetic and form-fit connections for secure attachment and adjustable tension, allowing for effective load transfer from accessories to the limb.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing orthotic systems are used, then hand function support is provided, but the systems are poorly adapted, expensive and restricting in terms of activities
Solution Approach 1:
The orthotic system is divided into separate modular components: a cuff base, a fixation element, and interchangeable accessories. Each component can be independently selected and combined based on specific activity requirements, allowing customization without increasing overall system complexity.
Solution Approach 2:
The cuff base and fixation element serve as universal components that can be combined with multiple different accessories to support various activities. The standardized interface allows one cuff system to adapt to multiple functions through accessory interchangeability.
2Strength
If a secure attachment system is used to transfer load forces, then load transfer from accessory to limb is enabled, but the system may become restrictive and less comfortable
Solution Approach 1:
The fixation element incorporates adjustable tensioning mechanisms that allow dynamic adaptation to different limb sizes and activity requirements. The system can be tightened or loosened as needed, providing secure load transfer when required while maintaining comfort during less demanding activities.
Solution Approach 2:
The cuff base utilizes flexible material construction that conforms to the limb shape, distributing load forces evenly across the limb surface. This flexible design maintains secure attachment and load transfer capability while enhancing comfort and reducing restriction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides comfort, intuitive operation, and adaptability to various activities by ensuring secure attachment and efficient force transfer, thereby enhancing the ability of individuals with hand function impairments to engage in daily routines and recreational activities.
Implementation Method 1
The interlocking between the lower shell and the fixation element comprises a magnetic connection, wherein in a body of the lower shell at least one first magnetic part is provided and in or at the fixation element at least one second magnetic part is provided such that by means of an attracting magnetic force between both magnetic parts the fixation element can be moved onto one side of the body of the lower shell or is or can be held on one side of the body of the lower shell.

AI summary
The present invention relates to a cuff (1) combinable with accessories for forming an orthotic system, comprising a cuff base (10) in form of a lower shell (11) and a fixation element (20) combinable into one sleeve attachable to a limb through direct or indirect interlocking with each other, wherein the lower shell (11) and the fixation element (20) provide a system that can be tightened around the limb by reducing a circumference formed by the lower shell (11) and the fixation element (20), such that load transfer from an accessory to the limb is enabled.
