Helmet Display Frame Resilient Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted display assemblies on helmets are prone to external forces like wind and require complex attachment and detachment procedures.
Innovation Solution
An information display assembly with a mechanism for rotation in the pitch and yaw directions, a sliding function, and auxiliary fixing portions, allowing the display unit to be securely attached to the inner side of the helmet using the frame's resiliency for easy attachment and detachment, and adjustable positioning according to individual user differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holder is fixed on the outer side of the helmet, then the head-mounted display assembly can be mounted on the helmet, but the display assembly is significantly affected by external forces such as traveling wind
Solution Approach 1:
The patent inverts the conventional mounting approach by placing the holder on the inner side of the helmet instead of the outer side. The holder's pressing parts contact the inner surface of the helmet, securing the display assembly from within the helmet interior, thereby protecting it from external forces like wind
2Reliability
If the holder is fixed on the helmet at plural holding parts, then the display assembly can be securely mounted, but complex handling is needed upon attachment or detachment
Solution Approach 1:
The holder is divided into multiple pressing parts that can independently contact different locations on the inner helmet surface. This segmentation allows the holder to securely mount the display assembly through distributed contact points while maintaining simple overall attachment and detachment operations
Solution Approach 2:
The pressing parts are designed with elastic pressing members that can dynamically adjust to the helmet's inner surface contours. This dynamic adaptation enables secure mounting without requiring complex manual adjustment during attachment and detachment
3Device complexity
If the display unit is rigidly fixed to the frame, then the mounting structure is simple, but the display unit cannot be adjusted for individual user differences
Solution Approach 1:
The connecting part incorporates rotational mechanisms that allow the display unit to rotate relative to the frame in pitch and yaw directions. This dynamic adjustment capability enables users to customize the display position for their individual needs while maintaining a relatively simple overall mounting structure
Solution Approach 2:
The connecting part allows adjustment of the display unit's angular parameters (pitch angle and yaw angle) relative to the frame. By changing these rotational parameters, the system adapts to different user requirements without requiring a completely complex mounting structure
4Stability of the object's composition
If the frame is made rigid, then the display unit positioning is stable, but the frame cannot be flexed for easy attachment and detachment
Solution Approach 1:
The frame is designed with elastic properties allowing it to be flexed during attachment and detachment operations. Once mounted, the frame maintains sufficient rigidity to provide stable positioning of the display unit, achieving both ease of operation and positioning stability through dynamic mechanical properties
5Reliability
If multiple connecting parts are used to attach the display unit to the frame, then the connection is more secure, but the effects of frame flexing on the display unit are amplified
Solution Approach 1:
The patent extracts the connecting function from multiple attachment points and concentrates it into a single connecting part located at the center of the display unit. This single connection point minimizes the transmission of frame flexing effects to the display unit while maintaining secure connection through the elastic pressing members of the holder

Function Achieved in This Case
The solution effectively reduces the impact of external forces, ensures easy and versatile attachment and detachment, and provides stable positioning of the display unit, enhancing user experience by minimizing the effects of helmet flexing on the display.

AI summary
Information display assembly that is hardly affected by an external force such as traveling wind when mounted on a helmet and that ensures easy attachability and detachability to and from the helmet. In an information display assembly including a display unit 2 displaying information, and a frame 3 connected to the display unit 2 to allow mounting of the display unit 2 on the helmet, the frame 3 has resiliency and is provided at opposite ends thereof with pressing parts 31, 32, and the pressing parts 31 and 32 are fixed on an inner side of the helmet by restoring force of resilient deformation. The display unit 2 and the frame 3 are commonly provided at a single location therebetween with a connecting part 4. The display unit 2 is displaceably supported relative to the frame 3.
