Vehicle Holder Pivot Lock for One-Hand Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular brackets require users to adjust and fix the angle using both hands, making it inconvenient and unsafe for drivers who need to operate the device while driving.
Innovation Solution
A holding device with a connecting body between the holder and base, featuring a pivotal element, limiting portion, and meshing portions, allowing users to adjust and fix the angle with a single hand by operating the limiting portion, which includes an upper and lower housing for a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional vehicular bracket uses a fixing knob on the rotating shaft to secure the angle, then the bracket can be fixed at a proper angle, but the user needs to operate with two hands simultaneously which is inconvenient and unsafe for drivers
Solution Approach 1:
The limiting portion automatically engages with the meshing portion to lock the support arm at the adjusted angle without requiring manual operation of a fixing knob. The system serves itself by using the rotational movement of the support arm to drive the limiting portion into the meshing portion, eliminating the need for separate locking action
Solution Approach 2:
The limiting portion acts as an intermediary mechanism between the support arm and the base. It translates the rotational movement of the support arm into automatic engagement with the meshing portion, providing a reliable lock without requiring direct manual operation of a fixing knob
2Adaptability or versatility
If the support arm is made adjustable with rotating shafts and fixing knobs, then the usage angle can be precisely adjusted, but the structure becomes complex and requires two-handed operation
Solution Approach 1:
The invention extracts the complex fixing knob mechanism from the rotating shaft and replaces it with a simplified limiting portion that automatically engages with the meshing portion. This removes unnecessary complexity while preserving the adjustable angle functionality
Solution Approach 2:
Instead of using a fixing knob to prevent rotation, the invention inverts the approach by using a limiting portion that allows free rotation during adjustment and then automatically locks when engaged with the meshing portion. The system transitions from active locking to passive automatic locking
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
Enables users to adjust the usage angle of the holding device with one hand, reducing inconvenience and safety risks while driving by simplifying the operation and maintaining the adjusted angle securely.
Implementation Method 1
An end of the pivotal element is pivotally connected with the base to allow the base to rotate
Implementation Method 2
The limiting portion rotates relative to the base via the pivotal element to be fastened to or detached from the second meshing portion
Implementation Method 3
The second meshing portion is disposed on the limiting portion and suited for being fastened with the first meshing portion

AI summary
A holding device includes a holder, a connecting body, and a base. The base has a first meshing portion. The connecting body is disposed between the holder and the base, and it has a pivotal element, a limiting portion, and a second meshing portion. The second meshing portion is disposed on the limiting portion. Two ends of a surface of the pivotal element are pivotally connected with the base and the limiting portion, respectively, and thus the base and the limiting portion may rotate relative to the pivotal element. When the limiting portion rotates relative to the pivotal element, the second meshing portion is meshed with or detached from the first meshing portion.
