Solution Overview

Problem

Existing protective helmets with integrated light devices face issues of fixed connections, making them difficult to detach and access, and when attached to size-adjustment systems, they interfere with the operation of these systems.

Innovation Solution

A protective helmet design featuring a rear light device housed in a rear opening with a mounting device that also serves as a strap fastening point, allowing for easy detachment and integration of the light device without obstructing the helmet's size adjustment functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the light device is fixedly integrated into the helmet shell or EPS body, then the light device is securely attached, but it cannot be detached or removed from the helmet

Engineering Contradiction:
Improvesecure attachmentVSAvoiddetachability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The light device is segmented from the helmet body through a removable mounting structure. The mounting structure includes a mounting element with a first engagement structure that interfaces with a second engagement structure on the light device, allowing the light device to be securely attached yet easily detached when needed.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the light device is attached to the size-adjustment system, then it is integrated into the helmet, but it interferes with the operation of the size adjustment system and is difficult to access

Engineering Contradiction:
ImproveintegrationVSAvoidaccessibility
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The light device mounting is extracted from the size-adjustment system area and relocated to a dedicated mounting location on the helmet shell. This separation eliminates interference with the size-adjustment system operation and improves accessibility to both the light device and the size-adjustment mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

3Illumination intensity

If the light device protrudes from the helmet, then it is easily visible, but it increases the overall size and may interfere with other helmet functions

Engineering Contradiction:
ImprovevisibilityVSAvoidoverall size
Core Design Contradiction:
Illumination intensityVSVolume of moving object

Solution Approach 1:

The light device is nested within a recess or opening in the helmet shell, with the mounting structure allowing it to be positioned flush with or slightly within the helmet's outer surface. This nesting approach maintains visibility of the light device while minimizing protrusion and avoiding interference with other helmet functions.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The invention relates to a protective helmet, in particular for sports, in particular a bicycle helmet, ski helmet or the like, having at least one rear lighting unit (30), said helmet comprising at least one opening (12) on the rear outer side thereof for receiving the rear lighting unit (30). A mounting device (20) releaseably holding the rear lighting unit (30) is disposed in the opening (12). The mounting device (20) is designed as a backwards mounting element for a strap for attaching the protective helmet (10) to the head of the wearer. The mounting device (20) in particular comprises attaching means (24, 24) by means of which said device is attached in the body of the protective helmet (10). The mounting device (20) is designed as a counter support for the strap, such that when the strap is subject to tensile loading, energy arising in the mounting device (20) is absorbed in the body of the protective helmet (10).
