Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing devices for mobile devices require hand-held operation, limiting the distance for taking pictures and are unable to securely clamp objects of various profiles or irregular shapes due to fixed functional ends and insufficient clamping force.
Innovation Solution
A hands-free dual clamp device with angle-adjustable clamping units and a connecting module, featuring a shaft module with spirally threaded outer and inner shafts, and claw-type clamping bodies that can rotate and adjust to fit different object shapes, allowing secure clamping of two objects without hand-held operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fixing apparatus is designed with one end for holding mobile device and other end for fixed attachment, then positioning without hands is achieved, but the range of objects to be held is limited and only one end can hold mobile device
Solution Approach 1:
The patent applies universality by making both ends of the fixing apparatus identical clamping units that can perform multiple functions. Each end can clamp mobile devices, attach to external objects, or connect to other clamping units, allowing the device to hold various objects at both ends and providing interchangeable functionality that expands the range of applicable objects.
Solution Approach 2:
The patent segments the fixing apparatus into two independent, identical clamping units connected by a connecting module. This segmentation allows each unit to function independently and be configured differently based on needs, enabling one end to hold a mobile device while the other end clamps a different object or connects to another unit.
2Adaptability or versatility
If clamping bodies are fixed in position, then structural simplicity is maintained, but adjustable angles and adaptation to various object profiles are limited
Solution Approach 1:
The patent applies dynamics by incorporating a shaft module with spiral threads that enables the lower clamping body to rotate relative to the upper clamping body. This rotational mechanism allows the clamping unit to adjust to various angles and adapt to different object profiles, transforming a static structure into a dynamic, adjustable system.
Solution Approach 2:
The patent changes the angular parameter of the clamping unit by allowing rotation of the lower clamping body around the shaft module. This parameter change enables the same clamping unit to accommodate objects of various shapes and orientations without requiring multiple different clamping unit designs.
3Strength
If single shaft connection is used between clamping bodies, then assembly simplicity is maintained, but secure clamping force and angle adjustability are insufficient
Solution Approach 1:
The patent applies the nested doll principle by placing an inner shaft with reverse spiral threads inside an outer shaft with standard spiral threads. Both shafts are nested within the same clamping unit structure, allowing them to work together to provide enhanced clamping force through their combined rotational mechanisms while maintaining a compact design.
Solution Approach 2:
The patent uses composite structural design by combining two shafts with opposite thread directions within the same clamping assembly. This composite approach creates a more robust clamping mechanism that can generate and maintain stronger clamping force compared to a single shaft, while the integrated design keeps the overall structure manageable.

Function Achieved in This Case
Enables hands-free operation for using mobile devices and securely clamps various shapes, including round or irregular objects, by allowing adjustable angles and clamping force, overcoming the limitations of conventional devices.
Implementation Method 1
The shaft module is spirally inserted through the upper and lower clamping bodies and is rotatable, so as to enable the upper and lower clamping bodies to be adjustable at angles with respect to each other

AI summary
A hands-free dual clamp device includes two clamping units, each having an upper clamping body, a lower clamping body, a mating portion, and a shaft module. The shaft module is spirally inserted through the upper and lower clamping bodies and is rotatable, so as to enable the upper and lower clamping bodies to be adjustable at angles with respect to each other and cooperatively form a clamping space for clamping an external object. A connecting module includes at least a connecting unit having two opposite end portions, which are respectively provided with a first connecting element and a second connecting element. The first connecting element connected to the mating portion of one of the clamping units, and the second connecting element connected to the mating portions of the other of the clamping units, so that the two clamping units are linked together with the connecting module.
