Head Suspension With Pivot Rear Support for Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headgear suspensions often require frequent adjustments and can be uncomfortable for extended wear, as they do not easily accommodate varying head sizes without removing the gear and can cause pressure points on the user's head.
Innovation Solution
A head suspension design featuring transition arms with pivots and a rear support portion that is pivotally connected, allowing for adjustable fit and reduced pressure points by distributing the weight and allowing the rear support to be positioned below common pressure points on the head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional head suspension designs are used, then the structure is simple, but the comfort for extended wear is poor and frequent adjustments are needed
Solution Approach 1:
The patent implements a dynamic suspension system where the rear support portion is pivotally connected to the headband via a pivot mechanism, allowing the support to move relative to the headband. This dynamic connection enables automatic adjustment and adaptation to head movements, eliminating the need for frequent manual adjustments while maintaining comfort during extended wear.
Solution Approach 2:
The suspension is divided into distinct functional segments: a headband portion, transition arms, and a rear support portion. Each segment performs a specific function and can move independently, allowing the system to adapt to various head sizes and shapes without requiring complex overall restructuring.
2Adaptability or versatility
If adjustable headbands are added to accommodate varying head sizes, then adaptability improves, but the device complexity increases
Solution Approach 1:
The pivotal connection between the rear support portion and headband creates a dynamic adjustment mechanism that automatically adapts to different head sizes. The pivot allows the support to rotate and position itself optimally based on the user's head dimensions, eliminating the need for complex manual adjustment mechanisms while maintaining high adaptability.
Solution Approach 2:
The suspension system performs self-adjustment through the pivotal connection mechanism. As the user wears the headgear, the rear support portion automatically positions itself at the optimal angle and location based on the head's shape and size, without requiring user intervention or complex adjustment mechanisms.
3Stability of the object's composition
If the rear support is positioned to secure the headgear, then stability improves, but pressure points are created on the user's head
Solution Approach 1:
The pivotal connection allows the rear support portion to dynamically adjust its position and angle, distributing the stabilizing force across a broader area of the head rather than concentrating it at a single fixed point. This dynamic positioning prevents pressure points while maintaining headgear stability during movement.
Solution Approach 2:
The transition arms are designed to extend at specific angles from the headband, creating optimized load distribution paths. This geometric configuration directs forces away from sensitive areas of the head while maintaining effective stabilization, reducing pressure points through strategic structural design.

AI summary
A head suspension includes a headband portion having a length and two transition arms. Each transition arm is coupled to the headband portion and extends away from the headband portion length at an angle greater than zero degrees. Each transition arm has a distal end and a pivot at the distal end. The pivot characterized by a pivot point and a rear support portion is pivotally connected to each pivot.
