Innovation Solution
A ventilated modular helmet system with a dual shell design that includes an inner shell with vents and an outer shell with vents and cooling packets, creating a climatic zone for enhanced heat dissipation and impact absorption, using flexible materials to distribute forces and reduce rotational trauma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a traditional single-shell helmet is used, then the helmet provides basic head protection, but it retains excessive heat and does not allow effective heat dissipation
Solution Approach 1:
The helmet is divided into two separate shells (inner shell and outer shell) with a climatic zone between them. This segmentation allows the inner shell to contact the user's head while the outer shell provides ventilation channels, enabling heat dissipation without compromising head protection.
Solution Approach 2:
The invention adds a spatial dimension by creating a climatic zone between the inner and outer shells. This intermediate space allows air circulation and heat dissipation pathways that are not available in traditional single-shell helmets, effectively reducing heat retention.
2Temperature
If a ventilated dual-shell helmet is used, then heat dissipation is improved, but the helmet may lack resistance to repeated impacts
Solution Approach 1:
The climatic zone between the inner and outer shells acts as a cushioning space that can absorb and distribute impact forces. Additionally, cushioning elements can be positioned within this zone to provide beforehand protection against repeated impacts while maintaining the ventilation function.
Solution Approach 2:
The helmet uses different materials for the inner shell (optimized for head contact and comfort) and the outer shell (optimized for impact resistance and ventilation). This composite structure allows each shell to be specialized for its primary function while working together to provide both heat dissipation and impact protection.
3Temperature
If cooling packets are added to the helmet, then heat dissipation is enhanced, but the device complexity increases
Solution Approach 1:
The cooling packets are positioned within the climatic zone as intermediary cooling elements. They facilitate heat transfer from the inner shell to the outer shell through the climatic zone, enhancing cooling effectiveness without requiring direct integration into the shell structures themselves.
