Vent Grille Mounting Claw Adjustment for Secure Device Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for vehicles, such as those using screws or suction cups, face challenges like difficulty in attachment and removal, damage to surfaces, and reduced suction power over time, while existing strap-based solutions struggle with secure attachment to ventilation grilles.
Innovation Solution
A fastening device with pivotably mounted claws and levers, featuring adjustable teeth and multiple claws arranged oppositely for secure engagement with ventilation openings, along with a PUR foam coating for safety and a ball head for attaching small devices, allowing for stable and damage-free attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to mount devices to the center console or dashboard, then the attachment is secure, but the surface is damaged and the device is difficult to remove
Solution Approach 1:
The patent introduces a mounting device with a mounting element that acts as an intermediary between the screw and the dashboard surface. The mounting element is inserted into a recess in the dashboard, allowing the screw to fasten the navigation device without directly damaging the dashboard surface. The mounting element can be removed and reused, leaving no permanent damage to the surface.
Solution Approach 2:
The mounting device is divided into separate components: a mounting element that interfaces with the dashboard recess, a screw for fastening, and a navigation device holder. This segmentation allows the mounting element to be inserted into the recess first, providing a damage-free interface, while the screw provides secure fastening without直接接触 the dashboard surface.
2Object-affected harmful factors
If suction cups are used to attach small devices to glass panes or dashboard, then the attachment is damage-free, but the suction power decreases over time and the device falls off
Solution Approach 1:
The mounting element serves as an intermediary that provides a mechanical interlocking solution rather than relying on suction force. The mounting element is inserted into a recess in the dashboard, creating a physical anchor point that maintains its holding power over time without degradation like suction cups.
Solution Approach 2:
The mounting device allows for easy installation and removal by the user, with the screw providing adjustable fastening force. The mounting element can be inserted and removed from the recess multiple times without losing its effectiveness, providing dynamic adaptability while maintaining reliable attachment.
3Ease of operation
If fastening straps are used to attach devices to ventilation grilles, then the attachment is relatively easy, but the secure attachment is difficult to achieve
Solution Approach 1:
The mounting element acts as an intermediary that engages with the ventilation grille structure through its recess interface. This provides a secure mechanical interlock that is more reliable than strap-based solutions while maintaining ease of installation through the simple insert-and-screw process.
Solution Approach 2:
The mounting element is designed to fit into the specific geometry of the ventilation grille recess, creating a precise mechanical fit. This geometric compatibility ensures secure attachment while allowing easy installation and removal.
4Stability of the object's composition
If multiple fastening claws are used to prevent slippage in ventilation openings, then the attachment stability is improved, but the device complexity increases
Solution Approach 1:
The mounting device uses multiple mounting elements (typically two) that are distributed across the navigation device housing. Each mounting element independently engages with the ventilation grille recess, providing stable attachment. This segmentation of the fastening function into multiple simple elements achieves stability without excessive complexity.

AI summary
The mounting device (1) has a mounting claw, which is arranged at a carrier (12). An adjustment device is arranged at a side of the carrier opposite to the claw. The position of the claw is adjusted relative to the carrier with the adjustment device (13). The mounting device is pivoted, and is partially coated with polyurethane foam. An independent claim is included for a method for mounting objects in vehicles.
