Hard Hat Visor Mounting for Accessory Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard hats and helmets face challenges in accommodating various safety equipment accessories, such as sun-visors, earmuffs, and lamps, due to differences in size and geometry, leading to interference and the need for frequent adjustments.
Innovation Solution
A universal mounting system with auxiliary ridges and interchangeable visors that accommodate different hard hat styles, featuring flexible and modular designs to allow seamless attachment and detachment of accessories without requiring adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed rigid visor is attached to the hard hat, then the sun-blocking protection is provided, but the visor interferes with accessories like earmuffs and requires frequent adjustments
Solution Approach 1:
The visor is designed with flexible material and attachment mechanisms that allow it to move and adjust dynamically. The visor can be positioned in multiple configurations (extended, retracted, folded) to accommodate different accessories and user preferences, eliminating the need for frequent adjustments while maintaining sun protection.
Solution Approach 2:
The visor is divided into multiple segments or portions (front portion, rear portion, side portions) that can move independently relative to each other. This segmentation allows the visor to adapt its shape and position to accommodate accessories like earmuffs while maintaining effective sun blocking coverage.
2Adaptability or versatility
If a universal mounting system is designed to accommodate various accessories, then the adaptability increases, but the device complexity increases
Solution Approach 1:
The mounting system incorporates auxiliary ridges and attachment locations that can accommodate multiple types of accessories (visor, earmuffs, lamps, face shields) using the same basic mounting interface. This universal design allows one mounting system to serve multiple functions without requiring separate complex mechanisms for each accessory type.
Solution Approach 2:
The mounting system uses adjustable parameters such as clip positions, ridge heights, and attachment point locations that can be modified to accommodate different accessory sizes and geometries. By changing these parameters rather than redesigning the entire mounting system, the complexity is reduced while maintaining versatility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure and comfortable attachment of multiple accessories across various hard hat styles, enhancing user compliance and safety by minimizing interference and simplifying the process of switching between use and storage positions.
Implementation Method 1
The visor includes a first portion and a second portion. The first portion extends circumferentially around at least a portion of the shell and extends radially outward from the shell forming a sun-blocking flange. The second portion is coupled to the first portion and is positioned adjacent to the accessory mounting location. The second portion is deformable relative to the first portion such that the second portion deforms to accommodate and cover a portion of an accessory coupled to the accessory mounting location

AI summary
A universal mounting system for a hard hat is provided that includes front and rear mounting locations and auxiliary ridges on either side. A visor is coupled to the hard hat mounting system in such a way as to provide access with minimal interference from the visor to the equipment attached to the mounting locations and ports in the auxiliary ridges. Various embodiments of visors enable modular designs that incorporate different materials and features of the visor. Parallel stretch zones enable folding and holding opposite brims of the visor. Enclosed elastic areas along the inner sides of visor provide user access to auxiliary ridges. Combinations of various accessories on hard hat and how the accessories work together on the universal mounting system are discussed: such as the interaction between visors, earmuffs, face shields, and lamps.
