Sawdust Helmet Buffer Structure for Comfort and Aesthetic Appeal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets with plastic buffer layers have single material and color, leading to increased production complexity and cost, poor texture, and limited comfort and softness, necessitating an improvement in both aesthetics and user experience.
Innovation Solution
A sawdust helmet with a buffer body composed of a sawdust layer and foam material layer, processed through extrusion and high temperature steam forming, allowing for customizable decorative patterns and enhanced softness and comfort through varied sawdust shapes, sizes, and materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic buffer layers (EPS, EPP) are used, then impact absorption is achieved, but the texture is single and comfort is limited
Solution Approach 1:
The patent uses a composite structure combining sawdust particles with binding agents to create a buffer layer that integrates natural organic materials with synthetic binders, achieving both impact absorption and improved texture/comfort characteristics
Solution Approach 2:
The sawdust buffer layer provides locally varied texture and softness characteristics throughout the helmet interior, creating different comfort zones that contact the wearer's head while maintaining overall structural integrity for impact protection
2Shape
If color ink or film is applied to beautify the buffer layer, then aesthetic appeal is improved, but processing complexity and production cost increase
Solution Approach 1:
The patent achieves aesthetic appeal through the natural color and texture variations of sawdust particles themselves, eliminating the need for additional color ink or film applications while maintaining visual appeal
Solution Approach 2:
The sawdust material inherently provides both functional buffering and aesthetic characteristics through its natural appearance, texture, and color variations, making the buffer layer self-sufficient for both protection and beautification without requiring additional processing steps
3Shape
If color ink or film is applied to the buffer layer, then aesthetic appeal is improved, but production cost increases
Solution Approach 1:
The natural color variations in sawdust particles provide aesthetic appeal without requiring additional coloring materials or films, eliminating associated costs
Solution Approach 2:
The sawdust buffer layer inherently provides aesthetic value through its natural appearance, eliminating the need for separate beautification materials and reducing overall production costs while maintaining visual appeal

AI summary
The present invention provides a sawdust helmet and a manufacturing method. The sawdust helmet comprises an outer housing; a buffer body containing sawdust is installed at the inner side of the outer housing; the buffer body is integrally formed, and the size of the buffer body is adapted with the size of the outer housing; a fabric inner cushion body is padded at the inner side of the buffer body; and a helmet belt is fixedly installed at the bottom of the outer housing. The buffer body is composed of a sawdust layer and a foam material layer. The sawdust layer is composed of cork chips or non-cork chips. The buffer body is composed of the sawdust layer and the foam material layer, and the decorative pattern formed by the sawdust can increase the beauty of the helmet.
