Conventional helmets lack effective mechanisms to absorb and dissipate blunt force impacts while also failing to quickly reconstitute their shape after deformation, and they do not offer adjustable rigidity for enhanced user safety.
Innovation Solution
A three-panel outer shell with an interlocking ridge system and a ripcord mechanism for deformation and reconstitution, combined with a spring mechanism for adjustable rigidity, along with additional layers such as gel-filled tubes and memory foam for impact absorption, and a skeletal framing for structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional helmets use a simple single-layer shell design, then the device complexity is low, but the ability to absorb and dissipate blunt force impacts is insufficient
Solution Approach 1:
The outer shell is divided into three separate panels (front panel, rear panel, and side panel) that can independently deform during impact. Each panel contains its own interlocking ridge system, allowing localized deformation and energy absorption while maintaining overall structural integrity. This segmentation enables complex impact absorption behavior without requiring an overly complex overall design.
Solution Approach 2:
The helmet employs a composite structure combining rigid outer shell material with integrated interlocking ridge systems made of contrasting materials (such as rubber or viscoelastic polymers). This composite approach allows the shell to provide structural strength while the ridge materials provide impact absorption and energy dissipation, resolving the contradiction between simplicity and effectiveness.
2Strength
If the outer shell is made rigid to provide protection, then the strength is improved, but the ability to quickly reconstitute shape after deformation is reduced
Solution Approach 1:
The interlocking ridge system introduces dynamic characteristics to the otherwise rigid shell. During impact, the ridges deform flexibly to absorb energy, then automatically return to their original positions due to the elastic properties of the ridge material. This dynamic behavior allows the shell to maintain rigidity for protection while enabling rapid shape recovery after deformation.
Solution Approach 2:
The ridge system changes the effective stiffness parameter of the shell locally. The ridges are designed with specific geometric parameters (height, spacing, cross-section) that allow them to be flexible during deformation but maintain rigidity in the undeformed state. This parameter optimization enables both strong protection and quick reconstitution.
3Adaptability or versatility
If the helmet structure is fixed with constant rigidity, then the manufacturing precision is improved, but the adaptability to different impact conditions is reduced
Solution Approach 1:
By dividing the shell into three panels with independent ridge systems, each panel can adapt to different impact conditions locally. The segmentation allows the helmet to provide optimized protection for various impact scenarios (frontal, rear, lateral) without requiring a completely different design for each case, maintaining manufacturing precision while improving adaptability.
Solution Approach 2:
The interlocking ridge system provides different mechanical properties at different locations and deformation stages. During normal use, the ridges maintain a fixed geometric configuration for structural precision. During impact, the local deformation of ridges provides adaptive energy absorption. This local quality variation enables both manufacturing precision and impact adaptability.
4Loss of energy
If the outer shell deforms significantly to absorb impact energy, then the impact absorption is improved, but the structural stability is reduced
Solution Approach 1:
The three-panel design with independent ridge systems allows impact energy to be absorbed locally in each panel rather than requiring the entire shell to deform. This segmentation maintains structural stability of the overall helmet while enabling significant energy absorption through localized ridge deformation. Each panel acts as an independent energy absorption unit.
Solution Approach 2:
The interlocking ridge system is pre-configured with geometric features (ridges, grooves, stoppers) that provide controlled deformation paths before impact occurs. This beforehand design ensures that during impact, the ridges deform in a predetermined manner that absorbs energy while maintaining structural stability through the stopper mechanisms that prevent excessive deformation.
