Helmet Visor Holder Mechanism for Stability and Drag Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head protection devices, such as helmets, face challenges in maintaining the stability of the visor when impacted externally, which can lead to the visor randomly detaching and causing safety hazards. Additionally, the protrusion of support members can increase air resistance, deteriorating driving performance.
Innovation Solution
A head protection device with a visor holder that includes a visor pressing part rotatably coupled to the outer frame, which is pressed by the visor to maintain its position, and a visor support that receives the visor corner, minimizing protrusion and air resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate member is provided to support the visor seated on the frame, then the coupled state of the frame and visor is maintained stably, but the member protrudes to an outside of the frame or visor increasing air resistance
Solution Approach 1:
The visor holder is rotatably coupled to the outer frame and is positioned to receive the visor when the visor is in the closed position. The holder is nested within the spatial envelope defined by the frame and visor assembly, such that it does not protrude outward when the visor is closed, thereby minimizing air resistance while maintaining support functionality
Solution Approach 2:
The visor holder is designed to be rotatable relative to the outer frame, allowing it to dynamically adjust its position. When the visor is closed, the holder rotates to a retracted position within the frame-visor envelope; when the visor is opened, the holder can rotate to accommodate the visor's movement, maintaining support while adapting to different states
2Ease of operation
If the visor is rotatably coupled to the frame, then the visor can be opened and closed, but a predetermined clearance is generated allowing the visor to randomly come off the frame
Solution Approach 1:
The visor holder acts as an intermediary component between the visor and the outer frame. It provides additional support and constraint to the visor during its rotational movement and when closed, preventing arbitrary separation while still allowing controlled opening and closing operations
Solution Approach 2:
The visor holder is pre-positioned and rotatably coupled to the outer frame before the visor is attached. This preliminary arrangement ensures that the holder is ready to provide support and prevent clearance-induced separation as soon as the visor is closed, without requiring additional activation steps
