Adjustable Head Massager Helmet with Distance Mechanism

The patent applies the dynamics principle by making the helmet size adjustable through a mechanical expansion structure. The helmet framework includes expandable components that allow the helmet circumference to be changed from a fixed size to an adjustable size, enabling adaptation to different user head sizes while maintaining a relatively simple overall structure.

The patent applies segmentation by dividing the helmet into modular components including a helmet framework, helmet liner, and adjustable expansion mechanisms. This segmentation allows the helmet size to be changed by adjusting specific segments (the expansion structure) without redesigning the entire helmet, thus achieving adaptability without excessive complexity.

The patent applies dynamics by incorporating adjustable massage components including variable pressure mechanisms, adjustable vibration frequencies, and modifiable massage pad configurations. These dynamic elements allow the massage technique to be customized and varied during use, preventing monotony while keeping the structural additions minimal.

The patent applies universality by designing a multi-functional massage device that can perform multiple massage techniques (pressure massage, vibration massage, heat massage) within a single integrated structure. This allows one device to provide varied massage experiences without requiring multiple separate devices, thus increasing adaptability while controlling overall complexity.
