Portable Device Holder With Adjustable Arms And Switch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders for portable devices are not universally compatible due to varying device sizes, leading to unnecessary costs and resource waste when replacing holders, and require uncomfortable manual manipulation or physical force for attachment and detachment, which can transmit impact to the device.
Innovation Solution
A holder with a main body, first and second arms, and switch mechanisms that allow for adjustable attachment and detachment of portable devices using simple button operations, reducing the need for multiple holders and minimizing physical force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a holder is designed for a specific portable device size, then the device can be stably held, but the holder cannot be used with devices of different sizes, leading to resource waste
Solution Approach 1:
The holder employs movable arms with adjustable positions that can dynamically adapt to different device sizes. The arms include first and second positions, allowing the holder to adjust its clamping width to match various portable device dimensions while maintaining stable holding. This dynamic adjustment mechanism resolves the contradiction by enabling both stability for the current device and adaptability for future devices of different sizes.
Solution Approach 2:
The holder changes its physical parameters (arm position, clamping force) to accommodate different device sizes. By adjusting the arm positions between first and second positions, the holder modifies its geometric parameters to match various device dimensions, thereby achieving both stable holding and broad compatibility without requiring multiple specialized holders.
2Strength
If manual force is applied to attach or detach the device, then the device can be secured, but impact may be transmitted to the device causing damage
Solution Approach 1:
The holder utilizes spring members that automatically generate the necessary attachment force without requiring manual force from the user. When the device is placed in the holder, the spring members autonomously expand to apply clamping force, securing the device without human intervention. This self-service mechanism eliminates impact transmission while maintaining adequate attachment strength.
Solution Approach 2:
The patent replaces the manual mechanical force application system with an elastic spring-based automatic force generation system. Instead of relying on user-applied mechanical force that can cause impact, the spring members provide controlled, gradual elastic force that secures the device without harmful impacts, substituting one mechanical approach for a more gentle alternative.
3Ease of operation
If multiple buttons are manipulated to control the arms, then precise control is achieved, but the operation becomes complex and uncomfortable
Solution Approach 1:
The holder merges multiple control functions into a single integrated switch mechanism. The first switch simultaneously controls both the first and second arms, coordinating their movement between first and second positions without requiring separate controls for each arm. This merging of control functions simplifies operation while managing the inherent mechanical complexity through unified control logic.
Solution Approach 2:
The single switch mechanism performs multiple functions: it controls both arms simultaneously, manages the transition between holding positions, and coordinates the spring member activation. This multi-functional switch design maintains ease of operation by providing a single control interface while handling the complex coordination required for dual-arm operation.

AI summary
A holder for a portable device includes: a main body having the portable device received on a front surface portion thereof; a first switch formed at a designated position of the front surface portion of the main body so as to be push into and protruded from the front surface portion; first and second arms formed at both side surfaces of the main body, and having a distance provided therebetween and varied by the first switch such that the portable device is attached or detached; and a second switch including a first button formed to be physically connected to the first arm inside the main body and a second button formed to be physically connected to the second arm inside the main body, and varying the distance between the first and second arms.
