Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adaptive peripherals for individuals with limited mobility are often custom-made and expensive, requiring extensive manual dexterity and expertise in CAD modeling for additive manufacturing, which can be a barrier for users needing customized adaptive grips for electronic devices.
Innovation Solution
The adaptive grip for digital styluses includes a body with an internal volume, keying feature, and retention feature, allowing for customization through additive manufacturing, with a movable transmission feature and customizable properties like material and texture to enhance user interaction and comfort, while maintaining interoperability with existing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adaptive peripherals are custom-made by hand, then they can be tailored to individual needs, but they become prohibitively expensive
Solution Approach 1:
The adaptive grip is divided into multiple components (body, cap, transmission feature) that can be manufactured separately through additive manufacturing and then assembled. This segmentation enables standardized production of individual parts, reducing overall manufacturing cost while maintaining customization capability through selective modification of specific components.
Solution Approach 2:
The patent utilizes additive manufacturing parameters (layer height, infill density, material selection) to customize the grip's physical properties without requiring complete custom fabrication. By changing manufacturing parameters rather than redesigning entire components, the system achieves individualization at lower cost.
2Adaptability or versatility
If conventional adaptive peripherals are custom-made, then they can accommodate specific mobility limitations, but they require extensive manual dexterity and CAD modeling expertise
Solution Approach 1:
The system enables users to customize their own adaptive grips by selecting from pre-defined options and configurations. The modular component design with standardized interfaces allows users to assemble and adjust their grips without requiring professional CAD modeling expertise, making the customization process accessible to end-users.
Solution Approach 2:
The patent provides pre-designed templates, standard component libraries, and preset configurations that eliminate the need for users to create designs from scratch. By preparing these resources in advance, the system reduces the skill barrier while still allowing substantial customization for specific mobility needs.
3Productivity
If additive manufacturing is used for custom adaptive grips, then manufacturing time and cost are reduced, but ensuring compatibility with existing devices becomes more challenging
Solution Approach 1:
The adaptive grip incorporates universal interfaces and standardized connection mechanisms that ensure compatibility with multiple device types. The keying features and retention mechanisms are designed to work with standard digital stylus specifications, allowing rapidly manufactured custom grips to reliably interface with existing devices without requiring device-specific redesign.

AI summary
An adaptive grip for a digital stylus includes a body having an internal volume and a keying feature in the internal volume to rotationally key the digital stylus to the body. The adaptive grip further includes a distal opening to allow an inking tip of the digital stylus to protrude from the internal volume and a retention feature to retain the digital stylus in the internal volume in a longitudinal direction.
