Helmet Neck Strap Holder With Fixing Bridge for Easy Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmet designs face challenges in reliably connecting a continuous neck strap to the helmet shell, particularly during automated manufacturing, as threading the strap through a ring-shaped holder can be difficult or impossible, especially when the strap is formed in one part with temple straps.
Innovation Solution
A holder with a coupling section featuring connection bridges and a fixing bridge that allows the neck strap to be secured without threading, by arranging a part of the strap through a free space and engaging it with the fixing bridge in a fixing position, ensuring a form-fitting connection to the helmet shell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ring-shaped holder structure is used to enclose the center section of the neck strap, then the connection reliability is improved, but the manufacturing complexity increases and automated assembly becomes difficult
Solution Approach 1:
The holder is divided into a coupling section with marginal sections and connection bridges, and a separate fixing bridge element. This segmentation allows the neck strap to be positioned on the coupling section first, then the fixing bridge is separately inserted to secure the connection, simplifying automated assembly while maintaining reliability.
Solution Approach 2:
The coupling section with its marginal sections and connection bridges is prepared in advance to receive and position the center section of the neck strap. This preliminary arrangement enables the strap to be correctly positioned before the fixing bridge is inserted, facilitating automated manufacturing processes.
2Device complexity
If the neck strap is formed in one part with temple straps, then the overall structure is simplified, but threading the strap through the holder becomes difficult or impossible
Solution Approach 1:
The holder structure is segmented into a coupling section for positioning and a separate fixing bridge for securing. This allows the continuous neck strap with integrated temple straps to be positioned on the coupling section without threading, and then secured by inserting the fixing bridge, making automated assembly feasible.
Solution Approach 2:
The coupling section with marginal sections and connection bridges acts as an intermediary structure that receives and positions the continuous neck strap before the fixing bridge secures it. This intermediary mechanism enables assembly of one-piece strap structures that would otherwise be difficult or impossible to thread through traditional holders.
3Reliability
If a closed ring-shaped structure is used to prevent detachment, then the security of connection is improved, but the assembly process becomes more complex
Solution Approach 1:
The closed ring function is segmented into the coupling section with marginal sections and connection bridges that define a receiving space, and a separate fixing bridge that inserts through this space. This segmentation achieves the security of a closed structure while simplifying assembly through separate component insertion.
Solution Approach 2:
The fixing bridge is designed to be movable between an insertion position and a fixed position where it connects the marginal sections. This dynamic element allows the holder to transition from an open assembly state to a closed secure state, maintaining connection security while enabling simple assembly.

AI summary
A holder includes a fastening section for fastening to a helmet shell and a coupling section for connecting to a neck strap. The coupling section has a first side, a second side, a first marginal section, a second marginal section, and one or more connection bridges that each permanently connect the first marginal section and the second marginal section to one another. At least one fixing bridge that can be moved from a position in which it does not connect the first and second marginal sections to one another into a fixing position in which it connects the first and second marginal sections to one another. A continuous center section of the neck strap can be arranged at the connection bridges and a part section of the center section can be brought through a free space where it can be engaged through by the at least one fixing.
