Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle helmets with raising/lowering visor mechanisms are complex to produce and difficult for users to assemble and disassemble, due to high constructive complexity and numerous cooperating components.
Innovation Solution
A helmet with a raising/lowering mechanism using magnetic-coupling members, including a base member and fastening pin, that simplifies assembly and disassembly by magnetic attraction and a reversible coupling system, allowing easy rotation and secure attachment of the visor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional raising/lowering mechanism with multiple cooperating components is used, then the visor can be raised and lowered effectively, but the constructive complexity increases and production becomes difficult and costly
Solution Approach 1:
The patent extracts the magnetic coupling function from a complex multi-component mechanical system, isolating the essential attraction force needed for visor attachment. By removing unnecessary intermediate components and relying solely on magnetic attraction between the base member and visor, the mechanism achieves reliable visor raising/lowering with minimal structural complexity.
Solution Approach 2:
The patent replaces traditional mechanical fastening systems (screws, clips, latches) with a magnetic coupling system. The magnetic attraction force between the base member and visor provides sufficient holding strength without requiring complex mechanical interlocking components, thereby simplifying the overall mechanism structure while maintaining reliable visor attachment.
2Reliability
If a complex raising/lowering mechanism with numerous members is used, then the visor can be securely attached, but the user finds it difficult to assemble and disassemble
Solution Approach 1:
The magnetic coupling system provides self-aligning and self-attaching characteristics. When the visor is brought near the base member, the magnetic attraction automatically draws them together and secures the visor in place without requiring precise manual alignment or complex assembly operations. This self-service mechanism maintains secure attachment while making user assembly and disassembly simple and intuitive.
3Reliability
If multiple cooperating members are used in the raising/lowering mechanism, then the visor can be constrained effectively, but the production cost increases
Solution Approach 1:
The patent merges the functions of multiple separate components into two main elements: the base member with magnetic coupling capability and the visor with integrated magnetic coupling. This consolidation eliminates the need for separate fasteners, hinges, and adjustment mechanisms, reducing part count and manufacturing complexity while maintaining effective visor constraint through the unified magnetic attachment system.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism reduces production complexity and costs, facilitates easy assembly and disassembly, and provides a simple, effective way to manage visor positioning without requiring complex operations.
Implementation Method 1
The raising/lowering mechanism in turn comprises: at least one base member, movably or integrally constrained to, or made in a single piece with, the outer shell, arranged in a side position with respect to the front opening; at least one fastening pin constrained inside a relative opening of the protective visor. The base member comprises a seat adapted to reversibly accommodate the fastening pin, and the mechanism comprises at least a first and a second magnetic-coupling members.
