Head Guard With Independent Face Shield And Object-Holder Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets with visors and object-holding devices are often not user-friendly or comfortable for wearers.
Innovation Solution
The face shield and object-holding device are independently adjustable relative to each other, with multiple pivot axes allowing for precise and easy adjustment, and are designed to pivot about a first axis that extends horizontally when worn, enhancing user-friendliness and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the face shield and object-holding device are coupled together, then the structure is simplified, but the adjustability and user comfort deteriorate
Solution Approach 1:
The patent divides the helmet system into independent adjustable modules: the face shield assembly can be adjusted independently from the object-holding device. Each component has its own adjustment mechanism with separate pivot axes, allowing the face shield to be positioned without affecting the object-holding device and vice versa. This segmentation resolves the contradiction by maintaining structural integration while enabling independent adjustability of each component.
2Adaptability or versatility
If multiple adjustment mechanisms are added, then the adjustability improves, but the device complexity increases
Solution Approach 1:
The patent combines multiple adjustment functions into integrated pivot mechanisms. The face shield assembly includes a first pivot axis for adjusting the shield angle and a second pivot axis for adjusting the lateral position, both merged into a single coordinated assembly. Similarly, the object-holding device has its own integrated pivot axes. This merging approach provides comprehensive adjustability while avoiding the complexity of separate independent mechanisms for each degree of freedom.
3Stability of the object's composition
If the face shield is made fixed, then the structural stability improves, but the user comfort and adaptability deteriorate
Solution Approach 1:
The patent implements dynamic adjustability where the face shield can be positioned at multiple fixed angles through a detent mechanism. The shield is capable of rotating about the first pivot axis and can be locked at various positions to provide stable protection. The object-holding device similarly allows dynamic positioning with detent stops. This dynamic design provides both stability when locked and adaptability when adjusting, resolving the contradiction between fixed stability and adjustable comfort.

AI summary
An arrangement comprises an adjustable face shield (2) and a face shield mounting device (4) for connection to a head guard base (1), as well as an adjustable object holding device (20) associated with the face shield (2). The object holding device (20) has a coupling device (21) for coupling to the head guard base (1) and an object holding device (22) arranged on the coupling device (21), and is pivotable as a whole about a first axis (3). The face shield (2) and the object holding device (20) are adjustable independently of each other. The first axis (3) coincides with a face shield adjustment axis (3).
