Segmented Arm Protector with Notched Elbow Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional arm protectors either fail to protect the elbow region or restrict arm bending due to their design, leading to discomfort and limited functionality in various activities.
Innovation Solution
A hand and forearm protector design that extends up to the elbow region, allowing for arm bending while providing protection, featuring a main body portion, hand portion, and extension portion with a notched section and adjustable closure mechanism for snug fit and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional arm protectors extend to cover the elbow region, then protection coverage is improved, but arm bending is restricted and comfort deteriorates
Solution Approach 1:
The arm protector is divided into multiple segments including a main body portion, an extension portion with a first notch, and a second notch. This segmentation allows the protector to conform to the elbow's anatomical structure, providing coverage while accommodating the bending motion through the notched openings that allow the arm to flex naturally.
Solution Approach 2:
The extension portion is configured with specific local features including the first notch positioned at a first location and the second notch positioned at a second location. These localized modifications provide protection where needed while creating strategic openings that maintain mobility, allowing the protector to have different functional properties in different regions.
2Ease of operation
If conventional arm protectors are designed to allow arm bending, then mobility is improved, but elbow region protection is insufficient
Solution Approach 1:
The extension portion extends in a direction substantially perpendicular to the longitudinal axis of the main body portion, creating a multi-dimensional configuration. This perpendicular extension allows the protector to wrap around the elbow region from multiple angles, providing comprehensive coverage while the notched openings maintain bending freedom through strategic dimensional placement.
3Strength
If arm protector material is made thicker for better protection, then impact resistance is improved, but comfort and flexibility deteriorate
Solution Approach 1:
The arm protector is designed as a flexible covering that can be configured to wrap around the arm and hand. The structure uses flexible material formation with strategic notched openings that maintain flexibility while providing protection, allowing the covering to conform to body contours and move with the user rather than restricting motion.
Solution Approach 2:
By dividing the protector into segmented portions with notched openings, the design distributes the protective function across multiple regions rather than requiring uniform thickness throughout. This allows thinner, more flexible material to be used in areas where full coverage is less critical while maintaining protection where needed.

AI summary
Arm protectors may be configured to protect a forearm of a user from bruising, scratches, cuts, bites, burns, and/or other injuries. The arm protector may include a body portion having a main body portion, a hand portion, and an extension portion. The main body portion may extend between the hand portion and the extension portion. The extension portion may extend from the main body portion toward an elbow of a user on a first side and toward an elbow crease of a user on a second side so as to protect a forearm, including an elbow region, of a user, while facilitating bending of the arm of the user.
