Adjustable Body-Worn Fastener for Easy Medical Corset Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accouterments for patients or care recipients, such as medical corsets, are difficult to attach due to complex operation requirements, especially for those with conditions like hemiplegia or fractures, and existing hook-type fastening parts often require specific directional engagement, making them less user-friendly.
Innovation Solution
The accouterment features male and female parts with adjustable engagement that allow for one-dimensional or two-dimensional arrangement of engagement elements, enabling easy fitting around the body and allowing for adjustable pressure application, with male parts having protrusions that align with the body's circumference to prevent loosening and female parts having loops that match the circumference direction for enhanced stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hook-type fastening part with limited engagement direction is used, then the fastening reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The fastening system is divided into multiple male engagement elements and female engagement elements arranged in arrays. Each element is simple in structure, but collectively they provide both reliable fastening and ease of operation through distributed engagement across multiple points
Solution Approach 2:
The male and female engagement elements are designed to work together in multiple configurations. The elements can engage in various orientations and the array arrangement allows for both secure fastening and simple donning/doffing operations, making the system versatile for different operational needs
2Strength
If a complex fastening operation is required, then the fastening strength is improved, but the ease of operation deteriorates
Solution Approach 1:
The fastening system uses multiple discrete engagement elements distributed in arrays rather than a single complex mechanism. This segmentation allows the fastening strength to be distributed across many simple engagement points, achieving high overall strength while maintaining simple individual element operations
Solution Approach 2:
The male and female engagement elements are designed to self-align and engage automatically when brought together. The protrusions and recesses guide the engagement process, allowing the fastening system to achieve strong bonding without requiring complex manual manipulation or alignment procedures

AI summary
Accouterment includes one or more accouterment components, and male and female parts secured onto separate locations of the one or more accouterment components, the male and female parts being engageable with one another so as to allow the accouterment to be kept fitted around a portion of human body, and a relative position between the male and female parts being adjustable to allow adjustment of a pressure applied from the accouterment to the portion of the human body when the male and female parts are engaged. The male part includes a first base layer, and a multiplicity of male engagement elements including male engagement elements arranged one-dimensionally or two-dimensionally on a main surface of the first base layer, each of the male engagement elements including a stem that stands on the main surface of the first base layer, and one single protrusion.
