Integrated Buttoning and Unbuttoning Assist Tool for Limited Dexterity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buttoning and unbuttoning assist devices are inadequate for conventional modern shirts and similar clothing, particularly for individuals with limited dexterity due to age, arthritis, amputation, or illness, as they do not effectively address the need for both buttoning and unbuttoning tasks without requiring assistance.
Innovation Solution
An integrated buttoning and unbuttoning assist tool featuring a tubular handle with a wire loop for buttoning and a spanner mechanism for unbuttoning, including a button hole expanding portion and a button holding portion, along with a zipper puller option using rare earth magnets for added functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional loop type button hookers are used, then buttoning can be assisted, but unbuttoning cannot be performed and another individual's help is required
Solution Approach 1:
The patent combines a button hooking device and an unbuttoning device into a single integrated tool. The button hooking portion includes a loop that can be inserted through buttonholes to pull buttons through, while the unbuttoning portion includes a jaw mechanism with upper and lower jaws that can grip and pull buttons away from buttonholes. By merging these two previously separate functions into one device, the patent enables both buttoning and unbuttoning operations without requiring assistance from another individual.
Solution Approach 2:
The integrated device performs multiple functions: it can both button and unbutton conventional shirt buttons, and it can also zip and unzip zippers. The button hooking portion handles buttoning tasks while the unbuttoning portion handles unbuttoning tasks, creating a universal tool that addresses all fastening needs for individuals with limited hand dexterity.
2Ease of operation
If separate buttoning and unbuttoning devices are used, then each function can be optimized, but device complexity increases and portability decreases
Solution Approach 1:
The patent merges two separate devices (button hooking device and unbuttoning device) into one integrated tool with a common handle. The button hooking portion and unbuttoning portion are both attached to the same handle member, reducing the number of separate devices from two to one while maintaining both functions.
Solution Approach 2:
The single integrated device performs both buttoning and unbuttoning functions, as well as zipper operations, eliminating the need for multiple separate devices and improving portability without sacrificing functional capability.
3Adaptability or versatility
If traditional buttoning assist devices are used, then simple buttoning tasks can be performed, but they are inadequate for conventional modern shirts and similar clothing
Solution Approach 1:
The unbuttoning portion features an upper jaw and lower jaw with specific geometric configurations designed to grip buttons of conventional modern shirts. The lower jaw includes a slot that receives the button shaft, and the upper jaw applies force to pull the button through the buttonhole. This localized geometric design adapts the device to work effectively with modern shirt button configurations.
Solution Approach 2:
The integrated device serves as an intermediary tool that bridges the gap between limited hand dexterity and the requirements of buttoning/unbuttoning modern shirts. The mechanical advantage provided by the handle and jaw mechanism compensates for reduced manual dexterity, enabling effective operation on conventional modern shirt buttons.
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 tool enables individuals with limited dexterity to independently button and unbutton conventional shirts and zippers, enhancing independence and reducing reliance on caregivers, with adjustable tool sizes and ergonomic design for ease of use.

AI summary
An integrated buttoning assist and unbuttoning assist device includes a tubular handle member; a button assist tool coupled to one end of the handle member and including a wire loop extending from one end of the tubular handle member, wherein the wire loop includes a button hole expanding portion adjacent the tubular handle and a button holding portion adjacent the button hole expanding portion; and an unbuttoning assist tool coupled to an opposed end of the handle member and including a spanner extending from the opposed end of the handle member, the spanner including a fixed lower jaw member having a pair of button engaging tangs separated by a slot which is configured to receive the threads or eye of a button therein, and the spanner including a fixed button engaging upper jaw member. A zipper puller may be coupled to the tubular handle member between the ends thereof.
