Motorcycle Barrier Panel With Angled Sides And Absorbing Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motorcycle race track barriers fail to adequately protect motorcyclists from high-speed impacts, leading to injuries and accidents, as they do not effectively absorb impact energy or prevent motorcyclists from falling off the track, and can be damaged by collisions, posing a risk to both riders and spectators.
Innovation Solution
A modular barrier system comprising a rectangular panel with a support layer, an absorbing layer, and a sliding layer, where the absorbing layer is coated and the sides are angled or cut to facilitate energy absorption and sliding, reducing the risk of motorcyclist falls and barrier damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a solid barrier made of wooden boards is used, then the barrier provides structural strength and prevents motorcyclists from falling off the track, but the barrier causes severe injuries to motorcyclists upon impact and can be damaged by collisions
Solution Approach 1:
The patent applies beforehand cushioning by placing a foam layer between the wooden board and the motorcyclist. This foam layer is pre-installed to absorb impact energy during collisions, reducing the harmful effects of the solid barrier on the motorcyclist while maintaining the structural strength of the wooden board framework.
Solution Approach 2:
The patent uses composite materials by combining wood (for structural strength) and foam (for impact absorption). This composite structure integrates the advantages of both materials: the wooden board provides rigidity and strength to prevent falls, while the foam layer provides cushioning to reduce impact injuries.
2Loss of energy
If the barrier is designed to be highly absorbing, then it reduces impact energy, but it may cause the motorcyclist to fall due to excessive energy absorption
Solution Approach 1:
The patent applies local quality by positioning the foam layer specifically at the impact zone (between the board and potential motorcyclist contact point) rather than uniformly throughout the entire barrier structure. This localized energy absorption reduces impact energy where needed while maintaining motorcyclist stability in other areas.
3Reliability
If a modular barrier system with multiple layers is used, then it improves safety and energy absorption, but it increases device complexity and manufacturing difficulty
Solution Approach 1:
The patent applies segmentation by dividing the barrier into distinct modular components: wooden board frames, foam layers, and protective strips. These segmented modules can be manufactured separately and assembled together, which improves safety performance through optimized energy absorption while managing complexity through standardized modular construction.
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 modular barrier system effectively absorbs impact energy and allows motorcycles to glide along the barrier without significant braking, reducing accidents and injuries by dissipating kinetic energy and preventing falls, while also protecting against damage from high-speed impacts.
Implementation Method 1
absorption of the impact energy through the absorbing layer
Implementation Method 2
dissipating kinetic energy
Implementation Method 3
thanks to the sliding layer, it moves the motorcycle along the barrier without significant braking

AI summary
Barrier module having a strip (2) attached to the panel (1) thereof. The panel (1) has a layer structure and consists of a sliding layer (7), an absorbing layer (8) and a support layer (9), as seen from the track. The sides (5, 6) of the panel (1) are cut at an angle a relative to the back surface (10) of the panel (1), which at the same time constitutes the outer surface of the support layer (9).
