Solution Overview

Problem

There is a need for a protective helmet that can be easily and quickly converted into two sets of helmets with different protective cushioning, while maintaining comfort, strength, safety, and adherence to industrial standards.

Innovation Solution

A dual helmet design featuring a first shell and a second shell that can be removably configured, along with a protective cushion arrangement that includes a first cushion and a second cushion, which can be configured to form two separate helmets or a combined helmet, ensuring compatibility with industrial standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If two separate helmets are carried for driver and pillion rider, then both riders can be protected, but storage space is insufficient in two-wheeler vehicles

Engineering Contradiction:

Improveprotective coverageVSAvoidstorage space

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent combines two separate helmets into a single integrated dual helmet structure where the first shell and second shell are connected through hinge joints, allowing them to be stored together in a compact form while providing protection for both driver and pillion rider when deployed

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The helmet is divided into separable segments (first shell and second shell) that can be independently positioned and adjusted. The shells can be folded along hinge joints to reduce storage volume, yet maintain full protective coverage when in use

Inventive Principle:

Principle #1Segmentation

2Volume of moving object

If a single helmet is used for both riders, then storage space is saved, but protective coverage is insufficient

Engineering Contradiction:

Improvestorage spaceVSAvoidprotective coverage

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The dual helmet structure serves multiple functions: it can protect the driver only, the pillion rider only, or both riders simultaneously by adjusting the position of the first and second shells. The same physical structure adapts to different protective needs without requiring separate helmets

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If two separate helmets are used, then protective coverage is ensured, but device complexity increases

Engineering Contradiction:

Improveprotective coverageVSAvoidhelmet structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The first shell and second shell are designed to nest within each other when folded, with one shell containing or overlapping the other. This nesting arrangement reduces the overall structural complexity compared to carrying two completely separate helmet systems

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

The present disclosure relates to a dual helmet that can be easily converted into two sets of helmets having protective cushioning, and which are comfortable, yet strong, safe, and up to the required standards. The helmet includes a first shell and a second shell defining a shell of a first helmet and a second helmet, respectively. The second shell is removably disposed over the first shell such that the helmet can be used as a single combine helmet when the shells are together, and further, the second shell can be separated from the first shell to form two separate helmets. The helmet includes a first cushion disposed within the first shell, and a second cushion for the second helmet being removably configured within the first cushion such that the second cushion can be separated by slightly bending it, and later can be configured with the second shell to form the second helmet and the first helmet, as required.
