Solution Overview

Problem

Existing elastic garments fail to provide adequate protection and support for the wrist and forearm during exercises that involve impact and stress, such as using kettlebells, as they lack adjustable reinforcement and sufficient impact protection.

Innovation Solution

A user-adjustable elastic wrist guard with longitudinal reinforcing elements and pockets that allow for the insertion of bendable inserts, providing customizable stiffness and protection, made from materials like elastic fabric with pockets for inserts that can be metal or plastic.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the elastic band includes reinforcing elements, then impact protection and support are improved, but flexibility and comfort deteriorate

Engineering Contradiction:

Improveimpact protectionVSAvoidflexibility

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The wrist guard is divided into multiple segments: an elastic band portion and multiple discrete reinforcing elements. These segments can be independently positioned and adjusted, allowing the user to place reinforcement where needed while maintaining flexibility in other areas. The pockets are segmented along the longitudinal axis, enabling selective insertion of reinforcing elements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wrist guard incorporates dynamic adjustability through removable and repositionable reinforcing elements. The pockets are designed to allow users to insert, remove, and reposition reinforcing elements along the longitudinal axis, enabling the garment to adapt its reinforcement level based on the user's needs and activity level.

Inventive Principle:

Principle #15Dynamics

2Strength

If the elastic band includes reinforcing elements, then support is improved, but device complexity increases

Engineering Contradiction:

ImprovesupportVSAvoidadjustable reinforcement structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The pockets are designed to accommodate multiple types of reinforcing elements (rigid inserts, flexible inserts, no inserts) and can be positioned at various locations along the longitudinal axis. This universal design allows a single wrist guard structure to provide multiple levels and types of support, reducing the need for multiple different garments.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The pockets are pre-positioned and pre-shaped within the elastic band during manufacturing, preparing the structure to receive reinforcing elements. This preliminary preparation simplifies the user's task of adding reinforcement, as they only need to insert elements into pre-formed pockets rather than constructing the reinforcement system themselves.

Inventive Principle:

Principle #10Preliminary action

3Object-affected harmful factors

If the elastic band is made more rigid with reinforcing elements, then impact protection is improved, but ease of use deteriorates

Engineering Contradiction:

Improveimpact protectionVSAvoidease of use

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Instead of making the entire elastic band rigid, reinforcing elements are placed locally at specific positions along the longitudinal axis where impact protection is most needed. The pockets are positioned at specific locations, allowing users to target reinforcement to specific areas while maintaining overall flexibility and ease of use.

Inventive Principle:

Principle #3Local quality

AI summary

A band is described for providing support and/or protection to the wearer. In one embodiment, the band is a wrist band having pockets for several longitudinal reinforcement elements. Thus, for example, a wrist band may be formed from an elastic material and be stitched to form pockets. In one embodiment, the pockets are closed, and the band is provided with a given amount of protection or support. In yet another embodiment, one or more pockets have an opening, which allows a user to adjust the amount of protection and/or support in each pocket.
