Solution Overview

Problem

Existing protective helmets lack efficient and sturdy solutions for detachably attaching accessories while being worn by the user, compromising safety and convenience.

Innovation Solution

An attachment device that engages with the functional band of a protective helmet, featuring a central stem and lateral prongs to securely attach accessories like sunshields or visors, allowing easy attachment and detachment without removing the helmet.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If accessories are attached to the helmet shell using existing solutions, then the helmet can be equipped with functional accessories, but the attachment mechanism lacks sturdiness and reliability when the helmet is being worn

Engineering Contradiction:

Improveaccessory attachment capabilityVSAvoidattachment sturdiness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The attachment device is divided into distinct functional segments: an upper portion for accessory attachment, a central stem for structural support, and lateral prongs for engagement with the functional band. This segmentation allows each component to be optimized for its specific function while working together to provide reliable attachment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment device utilizes three-dimensional engagement by extending lateral prongs perpendicular to the central stem, creating a multi-dimensional attachment geometry that engages with the functional band from multiple directions, thereby enhancing attachment sturdiness.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If accessories are attached to the helmet shell, then the helmet functionality is enhanced, but the attachment process becomes complex and requires helmet removal

Engineering Contradiction:

Improveaccessory attachment capabilityVSAvoidattachment convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The attachment device enables the user to attach and detach accessories independently without requiring helmet removal or specialized tools. The lateral prongs and engagement features are designed to be manipulated easily by hand, allowing self-service attachment operations.

Inventive Principle:

Principle #25Self-service

3Reliability

If a secure attachment mechanism is implemented, then accessory stability is improved, but the device structure becomes more complex

Engineering Contradiction:

Improveattachment sturdinessVSAvoidattachment device structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The functional band incorporates localized engagement features at specific positions where accessories need to be attached. These localized features (openings in the upper and lower walls) provide secure attachment points without requiring complex structures throughout the entire functional band.

Inventive Principle:

Principle #3Local quality

AI summary

An attachment device for attaching an accessory to a shell of a protective helmet is described, the shell comprising a shell body and a functional band around at least one front part and/or rear part of the shell body. The functional band comprises a central wall, an upper wall and a lower wall, and an attachment seat formed by an opening in the upper wall and in the lower wall. The attachment device comprises an upper portion from which a flat central stem and two lateral prongs inclined with respect to the plane defined by the central stem extend. The central stem has, at its free end, an foot extending in a direction perpendicular to the central stem and configured to engage with the opening in the lower wall.
