Segmented Finger Guard with Adjustable Fastening for Knuckle Flexion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing finger guards restrict finger motion and knuckle movement due to their inflexible design and lack of adjustable fastening, making it difficult to perform precise tasks and leading to instability during use.
Innovation Solution
A finger guard configured as protective armor with a reticulate pad network and adjustable fastening belt members that wrap around the finger, allowing for flexible motion and secure fitting tailored to the wearer's finger thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the finger guard is made as a rigid pipe-shaped structure for protection, then protective capability is improved, but finger motion flexibility deteriorates
Solution Approach 1:
The finger guard is divided into multiple unit plate pieces (first, second, third unit plate pieces) that are connected through loop members, creating a segmented structure. This segmentation allows each plate to move independently, providing protection while maintaining finger flexibility and range of motion.
Solution Approach 2:
The finger guard transitions from a rigid static structure to a dynamic adjustable structure. The loop members enable relative movement between plate pieces, and the fastening belt members allow adjustment of the guard's tightness, making the protective device adaptive to different finger positions and motions.
2Device complexity
If the finger guard uses a fixed size design for simplicity, then device complexity is reduced, but adaptability to different finger thicknesses deteriorates
Solution Approach 1:
The fastening belt members can be adjusted to different positions and tightened to different degrees, allowing the same finger guard structure to fit various finger thicknesses. This dynamic adjustment capability provides versatility without requiring multiple fixed-size guards.
Solution Approach 2:
The finger guard design incorporates universal features that allow it to serve multiple functions and fit different users. The adjustable fastening system and modular plate structure enable a single design to accommodate various finger sizes and shapes.
3Device complexity
If the finger guard lacks fastening means for simplicity, then device complexity is reduced, but stability during use deteriorates
Solution Approach 1:
The fastening system is segmented into multiple belt members (first and second fastening belt members) that can be independently adjusted and fastened. This segmentation allows for distributed fastening across different parts of the finger, improving overall stability while keeping each individual fastening element relatively simple.
4Strength
If the finger guard uses an inflexible pipe structure for protection, then protective capability is improved, but knuckle movement freedom deteriorates
Solution Approach 1:
The protective structure is divided into multiple plate pieces connected by loop members, allowing each segment to move independently. This enables the guard to accommodate knuckle movements and finger flexion while maintaining protective coverage.
Solution Approach 2:
The finger guard employs a flexible construction where thin plate pieces are connected by flexible loop members, creating a structure that can bend and flex with the finger. This flexible shell approach maintains protection while allowing full range of motion including knuckle movements.

AI summary
Disclosed is a finger guard. In an example embodiment, the finger guard includes a rectangular reticulate or netlike pad networked in a movable manner such that a plurality of unit plate pieces are connected to one another in four directions by a plurality of connecting loop members, and at least a pair of fastening belt members provided to extend or protrude parallel with one side of the reticulate pad, wherein the finger guard is configured to be worn in the form of a protective armor such that the reticulate pad covers and wraps around the dorsal side of a finger, upon which the finger guard is to be worn, and the respective fastening belt members pass the volar side of the finger to then be connected to be hooked on to one of the unit plate pieces in a state in which a portion of the volar side of the finger is opened and exposed in a length direction of the finger. With this configuration, the finger guard of the present disclosure is configured to be worn in the form of a protective armor such that fastening of the finger guard can be appropriately adjusted so as to be tailored to the thickness of a wearer's finger when the finger guard is worn for finger protection, thereby achieving enhanced functionality and quality for efficiently performing an elaborate and precise work by improving convenience in use and wearing comfort.
