Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with mobility impairments face challenges in performing everyday tasks due to limited physical dexterity and discomfort from poorly fitting adaptive devices, which hinder autonomy and personal fulfillment.
Innovation Solution
An adaptive hand device with a contoured body supporting the palm and wrist, featuring adjustable securing members and a retention mechanism for interchangeable implements, along with a storage device using magnetic guiderails for easy attachment and detachment of implements, allowing for comfortable and independent use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a poorly fitting adaptive device is used, then the device can be simple in structure, but it causes irritation or discomfort and inhibits the user's range of motion and coordination
Solution Approach 1:
The adaptive device is divided into multiple segments including a body portion, sidewalls, securing members, and retention members. Each segment can be independently adjusted or positioned to accommodate different hand sizes and shapes, allowing the device to maintain simplicity while providing a customized fit that preserves range of motion and coordination.
Solution Approach 2:
The device incorporates adjustable securing members with slots that allow dynamic adjustment of the fit. The retention members can be positioned at different locations on the body, enabling the device to adapt to various hand configurations while maintaining structural simplicity and avoiding irritation or discomfort.
2Device complexity
If an adaptive device with fixed implement is used, then the device structure can be simple, but it lacks versatility for different tasks
Solution Approach 1:
The retention members are designed to accommodate multiple types of implements through a universal interface system. The slots in the retention members can receive different implement configurations, allowing a single adaptive device structure to serve multiple functions for different daily tasks without increasing overall device complexity.
3Ease of operation
If a securing mechanism with multiple adjustment points is used, then the fit can be customized for comfort, but the device complexity increases
Solution Approach 1:
The securing members feature slots positioned at specific locations on the sidewalls where adjustment is most needed for comfort. Rather than providing continuous adjustment throughout the entire device, the slots are strategically placed to provide localized customization where it matters most, maintaining overall device simplicity while achieving comfortable fit.

AI summary
An adaptive device for a hand for individuals with mobility impairment. The adaptive device comprising a body; wherein the body has a proximal end and a distal end, and wherein the body supports a palm and a wrist when worn by a user. The adaptive device includes two sidewalls extending upward from the body and on opposite sides of the body from each other. At a proximal end of each sidewall, each sidewall includes a slot for receiving a securing member, and wherein the securing member removably secures the hand with the adaptive device when worn by the user. The adaptive device includes a retention member positioned on the body at the distal end and the retention member provides a separation between an index finger and a thumb of the hand, and the retention member removably couples with an interchangeable implement member.
