Helmet Interior Buffer Structure for Comfort and Impact Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmet interior materials struggle to provide both wearing comfort and effective head protection during accidents, particularly for users with varying head shapes and sizes, and fail to minimize direct contact forces during impacts.
Innovation Solution
The helmet interior material features a central buffer member and outer buffer members with protrusions that reduce direct contact area and enhance sliding, using materials like silicone for rigidity and varying heights and surface areas to minimize friction and maximize protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the interior material uses a uniform structure, then the manufacturing is simple, but it cannot provide adequate protection for users with various head shapes and sizes
Solution Approach 1:
The interior material is divided into multiple buffer parts (first buffer part, second buffer part, third buffer part) with different structures and properties. Each buffer part is positioned at specific locations to address different protection needs, allowing the material to adapt to various head shapes and sizes while maintaining manageable structural complexity through modular design
Solution Approach 2:
Different buffer parts are designed with distinct characteristics: the first buffer part has a smooth surface for comfort, the second buffer part has a rough surface for friction, and the third buffer part has varying hardness levels. This local differentiation enables the interior material to provide customized protection and comfort for different head regions, enhancing adaptability to diverse head shapes and sizes
2Stability of the object's composition
If the interior material increases friction to prevent sliding, then stability improves, but wearing comfort deteriorates
Solution Approach 1:
The interior material applies friction differently across various regions: the first buffer part has a smooth surface that minimizes friction for comfort, while the second buffer part has a rough surface that maximizes friction for stability. This localized quality differentiation allows the material to simultaneously provide both comfort and stability by matching surface properties to functional requirements at different locations
3Ease of operation
If the interior material uses soft material for comfort, then wearing comfort improves, but protection capability during accidents deteriorates
Solution Approach 1:
The interior material incorporates buffer parts with different hardness levels at specific locations. The third buffer part includes regions with varying hardness to provide enhanced protection at critical impact zones while maintaining softer regions for comfort. This local quality differentiation enables the material to simultaneously deliver wearing comfort through softer areas and accident protection through harder, more resilient areas
