Solution Overview

Problem

Conventional motorsports helmets face challenges in balancing aesthetic appeal with structural integrity, leading to limited design options and potential reluctance among riders to wear them due to unappealing designs.

Innovation Solution

A multi-part construction for the helmet, featuring an impact-resistant outer shell, an impact-attenuating liner, and a faceguard assembly with magnetic coupling, allowing for varied materials and manufacturing techniques to enhance both safety and aesthetics, including a modular design that enables specific areas to be 'tuned' for different levels of protection and styling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single-piece shell construction is used, then manufacturing is simpler and cost is lower, but design flexibility and aesthetic appeal are limited

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoiddesign flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The helmet shell is divided into multiple separate components including a main shell, faceguard assembly, and visor that can be manufactured independently using different techniques and materials, then assembled together. This segmentation enables both manufacturing efficiency and design versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular shell construction allows different components to serve multiple functions - the faceguard provides both aesthetic styling and protective function, while the visor serves both aesthetic and functional purposes. This multi-functionality resolves the contradiction between simplicity and versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Strength

If structural integrity is prioritized in specific areas, then safety is improved, but aesthetic appeal and design options are limited

Engineering Contradiction:
Improvestructural integrityVSAvoidaesthetic appearance
Core Design Contradiction:
StrengthVSShape

Solution Approach 1:

Different areas of the helmet shell have different structural properties optimized for their specific functions. High-strength materials and thicker sections are used in impact-prone areas, while aesthetically critical areas use materials and designs optimized for appearance. This local differentiation resolves the contradiction between strength and aesthetics.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The helmet uses composite material construction with different materials in different regions - such as carbon fiber in high-strength areas and fiberglass or plastic in aesthetic areas. This allows simultaneous optimization of both structural integrity and aesthetic appearance in different parts of the helmet.

Inventive Principle:
Principle #40Composite materials

3Reliability

If uniform protection is provided across the entire helmet, then safety consistency is improved, but weight and material usage increase

Engineering Contradiction:
Improveprotection consistencyVSAvoidhelmet weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The helmet provides tailored protection levels in different areas based on impact risk - higher protection in areas more susceptible to impact and lower protection in areas less prone to impact. This local differentiation maintains reliable protection where needed while reducing overall weight.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Instead of providing uniform excessive protection across the entire helmet, the design applies protection selectively - providing sufficient (but not excessive) protection in critical areas and minimal protection in non-critical areas, thereby optimizing the weight-protection ratio.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A motorsport helmet Includes a shell having a lower edge, a liner extending along an interior of the shell and a support portion coupled to the shell and extending between the shell and the liner adjacent the lower edge. In some configurations, when the helmet Is positioned on a DOT Standard No. 118 test head form, a portion of the lower edge is above the test line and a portion of the lower edge is below the test line and the support portion extends from the portion of the lower edge that is above the test line to a location below the test line. The helmet may also Include a muzzle adapted to cover the mouth and chin ares of a wearer, and a magnetic coupling assembly releasably coupling the muzzle to the shell.
