Helmet Shell Fixing System With Articulated Connecting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmet fixation systems are limited in their adjustability due to fixed connections between the headband and connecting elements, which restrict their ability to adapt to different head sizes effectively.
Innovation Solution
A helmet fixation system featuring a head size adjustment ring with a headband that can slide freely along a connecting element, allowing for variable positioning and detachment, enabling improved adjustability and secure anchoring to the helmet shell without additional locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the headband is firmly and inflexibly connected to the connecting elements, then the structural stability is improved, but the adjustability to the wearer's head is worsened
Solution Approach 1:
The connecting element is designed with two legs that can pivot relative to each other about a pivot axis, transforming the fixed rigid connection into a dynamic articulated connection. This allows the headband to adjust its position and angle while maintaining structural stability through the articulated joint mechanism.
Solution Approach 2:
The connecting element is divided into two separate legs that can move independently relative to each other. This segmentation allows each leg to adjust its position, enabling the headband to adapt to different head sizes and shapes while maintaining overall structural integrity.
2Reliability
If the headband is firmly connected to the connecting elements, then the fixation stability is improved, but the ease of adjustment is worsened
Solution Approach 1:
The articulated connecting element with pivoting legs provides a dynamic adjustment mechanism that is easy to operate. The user can simply move the legs to adjust the headband position, and the articulation naturally provides smooth motion while maintaining secure fixation once adjusted.
3Reliability
If the connecting elements are anchored firmly in the helmet shell, then the fixation reliability is improved, but the headband adjustability is worsened
Solution Approach 1:
The firm anchoring of the connecting element legs in the helmet shell provides stable fixation points, while the articulation between the legs allows the headband to adjust its position. The dynamic joint accommodates adjustment movements while the anchored legs maintain reliable fixation to the helmet shell.
4Ease of repair
If additional locking mechanisms are added to enable detachment, then the ease of assembly/disassembly is improved, but the device complexity is worsened
Solution Approach 1:
The articulated connecting element with pivoting legs provides inherent movement capability without requiring additional locking mechanisms. The natural articulation allows easy assembly and disassembly by simply moving the legs, avoiding the need for complex locks, screws, or clips while maintaining ease of operation.
