Helmet Ventilation Slider with Latching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets lack user-friendliness and effective climate control, with ventilation systems that are often complex and difficult to adjust.
Innovation Solution
A helmet with an adjustable ventilation arrangement featuring a slider device and latching mechanism that allows for zonal variation of airflow, enabling secure latched positions for customizable climate control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a ventilation arrangement with adjustable apertures is provided, then climate control capability is improved, but device complexity increases
Solution Approach 1:
The ventilation arrangement is divided into multiple independent ventilation devices, each with its own slider device and latching mechanism. This segmentation allows individual adjustment of different ventilation channels while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The latching device automatically secures the slider device in adjusted positions without requiring additional fastening operations. The slider device with integrated latching mechanism provides self-service functionality, allowing users to adjust and secure ventilation positions through a single simple action, thereby improving climate control capability while avoiding increased device complexity.
2Reliability
If a latching mechanism is added to secure slider positions, then adjustment security is improved, but device complexity increases
Solution Approach 1:
The latching mechanism is merged with the slider device into an integrated assembly. The latching device works directly with the slider device to secure adjusted positions, eliminating the need for separate fastening components and operations. This merging provides reliable adjustment security while avoiding the complexity increase that would result from adding independent latching components.
3Adaptability or versatility
If multiple latched positions are provided, then customization capability is improved, but ease of operation deteriorates
Solution Approach 1:
The latching device automatically engages with the slider device at predefined positions along the displacement path. As the slider device is moved to different positions, the latching mechanism self-activates to secure each position, providing multiple customized ventilation settings without requiring additional user actions. This self-service functionality maintains ease of operation while enabling extensive customization capability.

AI summary
A helmet is provided including a helmet shell for spatially defining a head receiving space and an adjustable ventilation arrangement which is in flow-connection with the head receiving space. The ventilation arrangement includes at least one first ventilation device having at least one first ventilation channel running in the helmet shell and a first slider device, which is assigned to the at least one first ventilation channel and which for varying a flow cross section of the at least one first ventilation channel is displaceable between a ventilation channel opening position and a ventilation channel closing position along the helmet shell. The at least one first ventilation device moreover includes a first latching device for latching the first slider device to secure it in at least one predefined latched position.
