Spring-Loaded Squeeze Holder for Fast Multi-Size Device Gripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for holding electronic devices, such as smartphones, often fail to accommodate a variety of sizes and provide a quick release mechanism, requiring users to manually adjust or remove the device, which can be cumbersome.
Innovation Solution
A system with a body portion and two gripping plates, interconnected with rotationally movable and linearly movable arms, featuring a spring-driven mechanism that allows for easy attachment and detachment of electronic devices, utilizing pivot points and gearing to translate rotational motion into linear movement, and incorporating magnetic or strap attachment systems for secure holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a manual adjustment mechanism is used to accommodate various device sizes, then the holder can fit different electronic devices, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The holder employs a spring-driven dynamic mechanism where two arms with gripping plates automatically adjust to accommodate different device sizes. The springs provide continuous force to maintain gripping pressure, allowing the system to adapt dynamically to various device dimensions without manual intervention. When a device is inserted, the arms naturally position themselves to fit the device width, and the springs maintain constant contact force.
Solution Approach 2:
The holder system is self-adjusting through its spring-loaded arms that automatically respond to the insertion of any electronic device. The mechanism serves itself by using the device's own presence to trigger the gripping action - when a device is placed between the arms, the springs automatically drive the arms together to secure the device, eliminating the need for user adjustment operations.
2Reliability
If a secure holding mechanism is used to firmly grip the device, then the device is held stably, but the release mechanism becomes complex and slow
Solution Approach 1:
The release lever is pre-configured in a neutral position where it naturally allows the springs to drive the arms together for secure gripping. When the user pushes the lever, it temporarily overcomes the spring force to open the arms for device insertion. After insertion, releasing the lever allows the springs to automatically and quickly close the arms around the device, performing the securing action in advance of any potential release need.
Solution Approach 2:
The release mechanism works by reversing the normal gripping action - instead of applying force to close the arms, the user applies force to the lever which opens the arms against the spring force. This inversion allows the springs to do the work of securing the device while the lever only needs to temporarily overcome that force for release, making the release action quick and simple.
3Measurement precision
If additional guides or tracks are added to maintain device centering, then the device positioning is more precise, but the device complexity increases
Solution Approach 1:
The patent removes the unnecessary guides and tracks from the design, relying instead on the inherent geometry of the arms and gripping plates to maintain device centering. The arms are designed with specific angles and the gripping plates have complementary shapes that naturally guide the device into a centered position without requiring additional constraint components. This extraction of unnecessary elements simplifies the overall device complexity.
Solution Approach 2:
The arms are designed with asymmetric geometry where the gripping plates have complementary asymmetric shapes that fit together with the device. This asymmetric design inherently guides the device into proper alignment and centering as it is inserted between the arms, eliminating the need for symmetric guide structures or additional centering mechanisms.

AI summary
A device holder includes a body portion, the body portion having a surface, a first gripping plate and a second gripping plate, each of the first and second gripping plates including a holding surface approximately perpendicular to the surface, a first lever and a second lever, each first and second lever coupled to the body portion at a pivot point via a spring and rotationally movable at the pivot points, and further includes a first sliding bracket coupled to the first gripping plate and a second sliding bracket coupled to the second gripping plate. The first lever is coupled to the first sliding bracket via a first aperture above the pivot point and a second aperture below the pivot point. The second lever is coupled to the second sliding bracket via a third aperture above the pivot point and a fourth aperture below the pivot point.
