Adjustable Helmet Holder for Variable Gear and Vehicle Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmet holders for vehicles lack the ability to securely accommodate a variety of helmet and head and neck support device sizes, and they often do not integrate well with different vehicle configurations, leading to potential damage to the helmet and vehicle.
Innovation Solution
A modular helmet holder system featuring an adjustable base with a U-shaped cavity, a linearly movable tongue with a post and flange, and supports that can be secured to various vehicle structures, allowing for secure retention of helmets and head and neck support devices regardless of size or vehicle configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed helmet holder design is used, then the structure is simple, but it cannot accommodate different helmet sizes and vehicle configurations
Solution Approach 1:
The holder incorporates a movable tongue that can slide along a slot in the base, allowing dynamic adjustment of the helmet retention position. This dynamic element enables the holder to adapt to different helmet sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The holder is divided into separate components: a base with a U-shaped cavity, a movable tongue with a post, and supports. This segmentation allows each component to be optimized independently and facilitates easy adjustment and installation in different vehicle configurations.
2Adaptability or versatility
If an adjustable helmet holder is used, then it can accommodate different helmet sizes, but the securing mechanism becomes more complex
Solution Approach 1:
The tongue is designed to move linearly within a slot in the base, providing adjustable positioning. The slot guides the movement while the securing member locks the tongue in place, creating a simple yet effective adjustable securing mechanism.
Solution Approach 2:
The slot acts as an intermediary element between the movable tongue and the base. It guides the tongue's movement and works with the securing member to enable easy adjustment without complex mechanisms.
3Reliability
If the helmet holder is secured firmly to prevent movement, then helmet security is improved, but the risk of damage to the vehicle interior increases
Solution Approach 1:
The holder uses multiple separate supports that can be independently positioned and secured. This distribution of securing points provides stable helmet retention while allowing the supports to be configured to match the vehicle's interior geometry, reducing stress concentration and potential damage.
Solution Approach 2:
The supports are designed to contact specific locations on the vehicle interior at optimized angles. This local optimization ensures firm helmet retention at the holder while minimizing harmful forces transmitted to the vehicle structure.
4Adaptability or versatility
If a universal helmet holder design is used, then it can be installed in different vehicle configurations, but the fit and security for specific vehicles may be compromised
Solution Approach 1:
The holder is divided into a base unit and multiple detachable supports. This segmentation allows the supports to be repositioned and reconfigured to match different vehicle interior geometries while maintaining the same secure retention performance across various vehicle types.
Solution Approach 2:
The base with its U-shaped cavity and slot design provides a universal platform that can accommodate different helmet sizes and work with various support configurations, enabling the same holder design to be effectively installed in different vehicle configurations while maintaining reliable retention.

AI summary
A holder for retaining a helmet and a head and neck support device connected to the helmet. The holder has a base and a tongue. The base has a top surface and a u-shaped cavity extending into the base from the top surface. The u-shaped cavity generally has two arms and a bottom wall. The head and neck support device is retained in the u-shaped cavity, and the tongue assists in retaining the helmet.
