Helmet Flow Guide Wing Aerodynamic Lift Design
Solution Overview
Problem
Existing helmets become heavy and cause pressure on the head and neck when additional devices are added, and their shape does not effectively manage fluid dynamics during use, such as in motorcycle riding or flight, leading to unsatisfactory safety and functionality.
Innovation Solution
A helmet design featuring a collapsible and detachable flow guide wing that generates a vertical upward lift when worn, using principles of fluid dynamics to reduce pressure and enhance control by guiding airflow, with the wing's position and direction adjusting to optimize lift and reduce centrifugal forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices such as camera, VR glasses, navigation unit and communication unit are added to the helmet, then more functions are achieved, but the helmet becomes increasingly heavy and causes pressure on the head and neck
Solution Approach 1:
The patent applies aerodynamic lift generated by the flow guide wing to counteract the gravitational force of the helmet and its attached devices. The wing is positioned to intercept oncoming fluid flow and generate upward lift that directly offsets the weight burden on the wearer's head and neck, enabling the helmet to carry multiple functional devices without proportionally increasing the burden on the wearer
2Weight of moving object
If carbon fiber composite is used to reduce helmet weight, then weight is reduced, but cost increases and safety may be compromised
Solution Approach 1:
The patent extracts the weight-carrying function from the helmet structure itself and transfers it to the aerodynamic lift system. This allows the helmet shell to be made from more economical materials while still achieving lightweight performance, as the structural burden is reduced and replaced by aerodynamic support
Solution Approach 2:
The patent changes the physical parameters of the helmet system by introducing aerodynamic lift generation. Instead of relying solely on material selection to reduce weight, the system uses fluid dynamic parameters (flow velocity, wing area, lift coefficient) to achieve weight compensation, providing a more cost-effective solution
3Reliability
If the helmet shape is optimized for safety, then protection is improved, but the ability to manage fluid dynamics and reduce pressure is insufficient
Solution Approach 1:
The flow guide wing generates aerodynamic lift that counteracts the harmful gravitational pressure on the wearer. The wing is specifically designed with appropriate angle of attack and surface area to generate sufficient lift to offset the helmet weight, converting the harmful downward force into useful upward support
Solution Approach 2:
The patent transitions from a static helmet design to a dynamic system that actively interacts with fluid flow. The flow guide wing is positioned and shaped to exploit relative motion between the helmet and surrounding fluid, generating adaptive lift that responds to flight or riding conditions, thereby reducing pressure dynamically rather than relying solely on passive structural design
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 flow guide wing reduces gravitational pressure on the head and neck, enhances control during turns and ascents/descents, and minimizes resistance, resulting in a safer and more energy-efficient use of the helmet across various applications, including air and water environments.
Implementation Method 1
the flow guide wing generates a vertical upward lift along a chord line
Implementation Method 2
