Four-Claw Holding Bracket With One-Way Brake for Stable Phone Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-free holding brackets for smartphones fail to provide a firm and stable grip due to vibrations from riding or driving, causing the phone to wobble and potentially fall off.
Innovation Solution
A holding bracket with four claw units, featuring a gearwheel mechanism, biasing units, and a one-way braking system that allows the claws to move simultaneously towards the center for secure gripping and release, ensuring stable phone retention and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If multiple gripping claws are used to hold the smartphone, then the gripping force is improved, but the stability deteriorates due to vibration causing wobble and potential phone drop
Solution Approach 1:
The gripping mechanism is segmented into four independent claw units, each capable of individual movement and gripping action. This segmentation allows each claw to independently adapt to vibrations while maintaining overall gripping stability, preventing the phone from wobbling or falling off during vehicle operation
Solution Approach 2:
The four claw units are combined with a common gearwheel mechanism that enables simultaneous movement of all claws. This merging ensures coordinated gripping action where all claws move together toward the center to securely hold the smartphone, providing both strong gripping force and enhanced stability against vibrations
2Ease of operation
If the claw units are designed to move swiftly outward for releasing the smartphone, then the ease of operation is improved, but the gripping stability deteriorates
Solution Approach 1:
The claw units are designed with dynamic movement capabilities through the gearwheel mechanism, allowing them to swiftly move outward for easy phone release when the release button is pressed. The one-way braking unit dynamically controls the movement direction, ensuring stable gripping during normal operation while enabling quick release when needed
Solution Approach 2:
The one-way braking unit acts as an intermediary between the gearwheel mechanism and the claw units. It mediates the movement control by allowing the claws to move inward for gripping while preventing unintended outward movement, thus maintaining gripping stability. When the release button is pressed, the braking unit releases, allowing swift outward movement for easy phone release
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 bracket securely grips the smartphone's corners using the gearwheel and biasing mechanism, preventing wobbling and easy release with a user-friendly button press, enhancing safety and usability during vehicle operations.
Implementation Method 1
a gearwheel is disposed rotatably... the toothed sections are meshed with different parts of the gearwheel such that rotation of the gearwheel results in simultaneous movement of the four claw units
Implementation Method 2
a biasing unit disposed in the main body for biasing the four claw units, thereby exposing the holding sections of the claw units to the exterior of the main body
Implementation Method 3
the one-way braking unit contacts with and is associated with one of the claw units such that when the one-way braking unit is under an unreleased condition, the four claw units are only movable in a single direction toward the gearwheel

AI summary
A holding bracket includes a main body having several guiding rails crossing one another at their centers, where a gearwheel is disposed rotatably; four claw units in the main body, each having a toothed section meshed with the gearwheel and a sliding section contacting a respective guiding rail and a holding section and a portion of the sliding exposed from the main body such that rotation of the gearwheel results in simultaneous movement of the claw units relative to the main body. A biasing unit is confined in the main body and associates with one claw unit. A one-way brake unit disposed in the main body is movable linearly and contacts the sliding section of one claw unit such that when the brake unit is under an unreleased condition, the four claw units are movable only in a single direction toward the gearwheel or the center of the main body.
