Sun Visor Clip Assembly for Vibration-Stable Eyewear Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clips for holding items like sunglasses and reading glasses on vehicle sun visors are prone to sliding off due to vibrations and require excessive clamping force, especially with heavier items, and lack stability during sun visor movement.
Innovation Solution
A clip design with a main body having two portions that pivot relative to each other, equipped with a biasing member and cushioning, allowing secure holding and featuring mounting means such as fasteners, retaining elements, or magnetic members for stable attachment to structural assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing clips are used to hold items on sun visors, then items can be held or gripped, but the clips slide off due to vehicle vibrations and require substantial holding force
Solution Approach 1:
The clip employs a dynamic mounting mechanism that allows the clip body to pivot and adapt to vibrations rather than resisting them rigidly. The pivotal connection between the clip body and sun visor enables the clip to move with vibrations while maintaining secure engagement through the biasing member's continuous contact pressure.
Solution Approach 2:
The clip is divided into distinct functional segments: a mounting portion that attaches to the sun visor, a pivotal connection mechanism, and a clamping portion with biasing member. This segmentation allows each part to perform its specific function optimally - the mounting portion provides stable attachment while the pivotal connection absorbs vibrational energy.
2Reliability
If existing clips are mounted on sun visors, then items can be held, but the clips require excessive clamping force to prevent sliding off during vibrations
Solution Approach 1:
A cushioning member is positioned between the clamping surfaces to protect held items from excessive pressure. This cushioning element distributes the clamping force evenly and prevents concentrated stress points that could damage delicate items like sunglasses frames or glass lenses.
Solution Approach 2:
The biasing member provides continuous contact pressure that adapts to vibration conditions, maintaining optimal clamping force without requiring excessive static pressure. The spring mechanism dynamically adjusts the clamping parameter based on real-time vibrational forces, ensuring secure retention while minimizing damage risk.
3Reliability
If clips are designed to hold items securely, then holding force increases, but the clips become more complex in structure
Solution Approach 1:
The mounting function and clamping function are merged into a single integrated clip assembly. The biasing member simultaneously provides both the mounting attachment force to the sun visor and the clamping force to hold items, eliminating the need for separate mounting hardware and simplifying the overall structure.
Solution Approach 2:
The biasing member is designed to automatically adjust and maintain optimal clamping force without external control or adjustment mechanisms. The spring-loaded system self-regulates the holding force based on the item being held and vibration conditions, eliminating complex control systems while ensuring sufficient retention.
Applied Scientific Principles
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 clip provides secure retention of items, protects them from damage, and maintains stability during vehicle vibrations, enabling easy access and preventing loss or displacement.
Implementation Method 1
A biasing member is mounted between the first and second body portions for biasing the clip to the closed state
Implementation Method 2
a cushioning member is disposed between the first and second body portions for protecting an article
Implementation Method 3
the mounting means comprises a magnetic member configured for secure retention on the structural assembly

AI summary
The invention is directed to a clip for holding articles includes a main body having a first body portion and a second body portion mounted to undergo pivotal movement relative to the first body portion for selectively positioning the clip between an open state and a closed state. The first state of the clip is configured to allow an article to be positioned between the first and second body portions, and the closed state of the article is configured to securely hold the article between the first and second body portions. A biasing member is mounted between the first and second body portions for biasing the clip to the closed state. The clip is configured for placement in the open state by pivotal movement of the first body portion relative to the second body portion against the biasing force of the biasing member. The invention is also directed to a sun visor assembly equipped with the clip.
