Helmet-Mounted Multidirectional Control Plate for Gloved Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for helmets, such as those used by motorcycle riders, fail to provide a user interface that is both safe and convenient to operate, especially when wearing gloves, as they require complex hand movements or precise button presses.
Innovation Solution
A user interface device with a scroll-activated element and a pressure-activated multidirectional tiltable/pushable plate, embedded within a housing that can be mounted on a helmet, allowing easy operation by simple hand or finger movements, including discrete keys and a clickable element, which converts activations into control signals for the communication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button controls are used on helmet-mounted communication systems, then the system can be operated, but the operation becomes difficult and unsafe when wearing gloves
Solution Approach 1:
The patent changes the operational parameter from precise button pressing to rotational scrolling motion. The scroll-activated element responds to rotational movement rather than requiring precise linear pressing, making it operable with gloved hands while maintaining safety and reliability.
Solution Approach 2:
The control interface is segmented into distinct functional elements: a scroll-activated element for navigation and selection, and a separate clickable element for confirmation. This segmentation allows each element to be optimized for its specific function, with the scroll element handling browsing and selection without requiring precise positioning.
2Measurement precision
If complex hand movements are required for operation, then precise control can be achieved, but safety and convenience are compromised
Solution Approach 1:
The scroll-activated element provides dynamic control through rotational motion, allowing the user to navigate through options by scrolling and then confirm selection through a separate clickable action. This dynamic interface maintains precision while simplifying the physical movements required, especially when wearing gloves.
3Adaptability or versatility
If multiple separate controls are provided for different functions, then comprehensive control capability is achieved, but device complexity increases
Solution Approach 1:
The scroll-activated element serves multiple functions: it can be rotated to navigate through options and can be clicked to confirm selections. The clickable element works in conjunction with the scroll element to provide both navigation and confirmation capabilities, reducing the need for separate dedicated buttons for each function.

AI summary
A user interface device for applying control signals to a communication system, comprising: at least one pressure-activated multidirectional tiltable/pushable plate with multiple pressureable areas, wherein each of said pressureable areas activates a corresponding pressure element that is located under said plate, wherein each activation of a specific pressure element defines an action which is respectively performed upon tilting- pressing of said plate towards the location of the respective pressure element.
