Universal Device Holder with Synchronized Arc Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing a universal device holder for electronic devices that can fit various seat configurations and accommodate different sizes of electronic devices, such as smartphones and tablets, is challenging due to the limited space between a seat back and the seat in front, and the need for a holder that can adapt to diverse electronic device sizes.
Innovation Solution
A device holder with upper and lower arc arms connected to a drive device, which enables synchronized movement between non-use and use positions, utilizing gears and a push-push mechanism to adjust and lock the arms for secure device placement, allowing for universal fitment and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a device holder is designed to fit various seat configurations and accommodate different electronic device sizes, then the adaptability is improved, but the device complexity increases due to the need for adjustable mechanisms and synchronized movement control
Solution Approach 1:
The patent combines the adjustment mechanisms for upper and lower arc arms into a single integrated drive device. The drive device includes a main gear that simultaneously controls both arms through interconnected gear racks, merging multiple adjustment functions into one unified mechanism. This reduces overall system complexity while maintaining the ability to accommodate various seat configurations and device sizes.
Solution Approach 2:
The device holder is designed with universal adaptability through its adjustable arc arms that can position themselves to fit different electronic device sizes and various seat configurations. The same drive device and gear mechanism serve multiple functions: adjusting upper arm position, adjusting lower arm position, and maintaining synchronized movement, thereby achieving multi-functionality without proportionally increasing complexity.
2Ease of operation
If the upper and lower arc arms are made moveable between non-use and use positions with synchronized movement, then the ease of operation is improved, but the device complexity increases due to the synchronized movement mechanism
Solution Approach 1:
The drive device merges the control functions of both upper and lower arc arms into a single integrated mechanism. The main gear connects to both gear racks, allowing one input force to simultaneously control both arms' movement between non-use and use positions. This unified approach simplifies operation while the mechanical linkage inherently provides the synchronized movement function.
Solution Approach 2:
The gear mechanism automatically maintains synchronized movement of the upper and lower arc arms without requiring external control or coordination. When one arm is adjusted, the mechanical connection through the gear system automatically adjusts the other arm in corresponding fashion, making the system self-regulating and reducing the operational complexity for the user.
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 device holder effectively adapts to different seat configurations and electronic device sizes, providing secure and adjustable placement for various devices while being compact and user-friendly, ensuring compatibility with multiple seat types and electronic device dimensions.
Implementation Method 1
The drive device may include a main gear, an upper secondary gear, and a lower secondary gear. The upper arc arm may include an upper gear rack and the lower arc arm includes a lower gear rack. The upper secondary gear is engaged with the upper gear rack and the main gear, respectively, and the lower secondary gear is engaged with the lower gear rack and the main gear, respectively.
