Helmet Holding Device Force Absorber Strap Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets may not adequately absorb impact forces, risking transmission of these forces directly to the user's head due to deformation or breakage of the holding device, which can be dangerous and does not meet safety standards.
Innovation Solution
A helmet design featuring a holding device with a force absorber having at least three orifices for strap passage, where the straps are folded 180° around one edge of an orifice, forming a loop that absorbs impact forces by deforming locally and dissipating energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a cord is used to join straps in the holding device, then the helmet structure is simple, but the cord may break during impact and transmit dangerous forces to the user's head
Solution Approach 1:
The force absorber is pre-installed in the holding device with straps configured to engage with it. Before any impact occurs, the system is prepared to absorb forces through the deformable force absorber, preventing the cord from breaking and protecting the user's head from dangerous force transmission.
2Stability of the object's composition
If the holding device is made rigid to maintain structural stability, then the helmet maintains its shape, but impact forces are transmitted entirely to the user's skull
Solution Approach 1:
The force absorber is made of an elastically deformable material, changing the mechanical parameter of the holding device from rigid to flexible in the impact zone. This allows the force absorber to deform and absorb impact energy, reducing the harmful forces transmitted to the user's head while maintaining overall structural stability.
3Reliability
If a force absorber with multiple orifices and folded straps is used, then impact forces are effectively absorbed, but the device complexity increases
Solution Approach 1:
The force absorber integrates multiple functions into a single component: it serves as both a structural element of the holding device and an impact absorption mechanism. The straps are configured to pass through multiple orifices and fold around edges, combining the fastening function with the force absorption function, thereby reducing overall device complexity despite the enhanced safety features.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The helmet effectively reduces the transmission of impact forces to the user's head by using the force absorber to dissipate energy, enhancing safety and comfort while meeting safety standards.
Implementation Method 1
the strap tends to close around this edge and transmit part of this force to the absorber, which may deform locally to dissipate part of this force

AI summary
A helmet including an outer shell and a holding device which includes a perimeter forming a closed loop, at least two straps attached to the perimeter and/or to the shell and a support cushion. The holding device further includes a force absorber provided with at least three orifices for the passage of at least one strap, each orifice connecting a first and a second face of the force absorber. At least one strap passes successively through a first orifice, a second orifice and a third orifice, extending on the first face between the first orifice and the second orifice and on the second face between the second orifice and the third orifice. The strap is folded 180° around an edge of the second orifice.
