Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets with visors suffer from loose power cable connections that can lead to accidental disconnection, potentially damaging electrical components.
Innovation Solution
A visor assembly with an integrated cable retaining element and connection assembly that securely attaches the power cable to the visor, redirecting forces to prevent disconnection and maintaining a continuous sealing member for improved sealing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power cable is loosely connected to the helmet, then the cable management is simple, but the connection is prone to accidental disconnection which can damage electrical components
Solution Approach 1:
The connection system is divided into separate components: a cable retaining element integrated to the visor, a connection assembly with electrical connector, and a sealing member. This segmentation allows each component to perform its specific function while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The cable retaining element is pre-integrated to the visor structure, and the sealing member is pre-positioned to maintain continuity. This preliminary preparation ensures that when the power cable is connected, it is immediately secured and sealed, preventing accidental disconnection and maintaining connection reliability.
2Reliability
If wiring is necessary between the helmet and the visor, then power can be delivered to the heating system, but the device complexity increases and accidental disconnection risk remains
Solution Approach 1:
The cable retaining element, connection assembly, and sealing member are merged into an integrated system where the retaining element is attached to the visor and the sealing member maintains continuity. This merging reduces wiring complexity while ensuring reliable power delivery to the heating system.
Solution Approach 2:
The connection assembly acts as an intermediary between the power cable and the heating system, providing a secure electrical connection. The sealing member serves as an intermediary to maintain the sealed environment, preventing moisture ingress while allowing power delivery.
3Reliability
If the power cable is securely attached to the visor, then accidental disconnection is prevented, but the device complexity increases
Solution Approach 1:
The cable retaining element serves multiple functions: it secures the power cable to the visor, maintains cable alignment, and works in conjunction with the sealing member to preserve the sealed environment. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity while maintaining secure attachment.
4Reliability
If a continuous sealing member is maintained, then sealing efficiency is improved, but the device complexity increases due to additional components
Solution Approach 1:
The sealing member is positioned locally at critical areas where sealing is needed, such as around the connection assembly and cable retention points. This localized approach maintains sealing efficiency without requiring a complete sealing system throughout the entire visor, thereby reducing overall device complexity.

AI summary
A visor assembly of a helmet having a helmet shell is provided. The visor assembly includes a visor pivotally connectable to the helmet shell via left and right visor mounting sections. The visor has an inner surface facing a cavity of the helmet shell and an outer surface, and is provided with a heating system. The visor assembly further has a connection assembly including an electrical connector located on the outer surface of the visor proximate a front portion thereof. The electrical connector is operatively connected to the heating system and is adapted to be connected to a power cable for providing electrical power to the heating system. The visor assembly also includes a cable retaining element located on the outer surface of the visor proximate one of the visor mounting sections. The cable retaining element has a clip adapted to removably attach the power cable on the visor.
