Sun Visor Guide Rod With Integrated Window-Breaking Impact Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun visor and window breaker tool configurations in vehicles occupy excessive space and lack integration, making them less efficient in terms of space utilization and user convenience.
Innovation Solution
A sun visor assembly that incorporates a guide rod with a built-in impact point, allowing the visor to be rotatable and the guide rod to function as a window breaker tool when disassembled, integrating both functions into a single component that can be mounted to the vehicle's interior ceiling and used to break a window by focusing force through a conical impact point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate window breaker tool is provided in the vehicle, then window breaking function is available, but space consumption increases and device complexity increases
Solution Approach 1:
The patent combines the sun visor and window breaker tool into a single integrated assembly. The guide rod with impact point is incorporated into the sun visor structure, allowing the visor to serve dual purposes: blocking sunlight and breaking emergency windows. This merging eliminates the need for a separate window breaker tool, reducing device complexity while maintaining the window breaking function.
Solution Approach 2:
The sun visor assembly is designed to perform multiple functions: it blocks sunlight during normal operation and serves as a window breaker tool in emergency situations. The guide rod can be disassembled from the visor to function as a standalone window breaker, providing universal functionality across different usage scenarios without requiring additional components.
2Adaptability or versatility
If a separate window breaker tool is provided in the vehicle, then window breaking function is available, but space utilization becomes less efficient
Solution Approach 1:
The window breaker function is merged into the sun visor assembly, eliminating the need for a separate tool that would occupy additional space in the vehicle. The guide rod with impact point is stored within or integrated with the visor structure, ensuring that the window breaking capability is achieved without increasing overall space consumption.
3Adaptability or versatility
If the guide rod is disassembled from the mount, then window breaking function is accessible, but structural stability decreases
Solution Approach 1:
The guide rod is designed as a separable component that can be easily detached from the mount. The segmentation allows the guide rod to function as part of the assembled visor for structural stability, while also enabling independent removal for window breaking operations. The impact point at the terminal end provides the necessary functionality when disassembled.

AI summary
A sun visor assembly for a vehicle that includes a mount configured to be connected to the vehicle. A guide rod having a first portion that includes a head and a second portion with a terminal end is operably coupled to the mount via the head. An impact point is at the terminal end of the second portion. The guide rod and the impact point are configured for use as a window breaker tool in a disassembled position. A visor is operably coupled to the guide rod in an assembled position and is rotatable about the guide rod from a first position to a second position. The visor includes a channel defined within the visor that is configured to receive the guide rod.
