Pivoting Visor Clip With Cushioning for Vibration Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clips for holding items like sunglasses and reading glasses on structural assemblies, such as sun visors, face issues with securely retaining the items due to vibrations, which require substantial holding force and often lead to the clips sliding off during vehicle movements or adjustments.
Innovation Solution
A clip design featuring a main body with pivotal movement, a biasing member for secure closure, and cushioning for protection, along with various mounting options like fasteners, magnetic members, adhesive, suction cups, or hook and loop fasteners for stable attachment to structural assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing clips are mounted on sun visors to hold items, then items can be stored on the visor, but the clips slide off due to vehicle vibrations and movements
Solution Approach 1:
The clip incorporates a pivotable body portion that can rotate relative to the mounting surface, allowing the clip to dynamically adjust its position and maintain engagement with the visor during vehicle vibrations and movements, preventing the clip from sliding off
Solution Approach 2:
The clip uses a spring-loaded biasing member that changes the contact force parameter between the clip and the mounting surface, providing adaptive holding pressure that maintains secure retention under varying vibration conditions
2Reliability
If existing clips provide holding force to secure items against vibrations, then items can be retained, but substantial clamping force is required which may damage the held items
Solution Approach 1:
The clip incorporates a cushioning member positioned between the clip body and the held item that provides protective cushioning in advance, absorbing excessive clamping force and preventing damage to the held items while still maintaining secure retention under vibration conditions
3Reliability
If clips are designed to hold items securely, then holding force is sufficient, but the clips become difficult to open and close
Solution Approach 1:
The clip uses a pivotable body portion that rotates on a pivot axis, creating a mechanical advantage that reduces the force required to open and close the clip while maintaining sufficient holding force when closed, making the clip easy to operate
Solution Approach 2:
The clip divides the body into a stationary body portion and a pivotable body portion that can rotate independently, allowing the closing action to be applied to only a portion of the clip structure, reducing the overall force needed to secure the item
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 effectively secures items by providing sufficient holding force and protection against vibrations and movements, ensuring items remain attached without sliding off, while allowing easy access and versatile mounting on different surfaces.
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 magnetic retention to a structural assembly

AI summary
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.
