Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable telescopic brackets for mobile communication devices require two hands to extend and retract telescoping clamp members, leading to difficulties in clamping and potential damage to the device.
Innovation Solution
An adjustable telescopic bracket design featuring a main body with a sliding groove, a driving assembly with a gearing portion, an elastic assembly, and telescopic members with a resisting portion, allowing simultaneous extension and retraction with a single hand using a pre-force generated by the elastic assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two telescoping clamp members are individually disposed and extended separately, then the clamping mechanism can be adjusted to fit different device sizes, but the user requires two hands to operate them respectively, reducing ease of operation
Solution Approach 1:
The patent combines two independently operable telescoping clamp members into a single integrated unit with a common driving mechanism. The first and second telescoping clamp members are both driven by the same driving assembly, allowing them to extend and retract simultaneously through a single operating section, thereby enabling single-hand operation while maintaining adjustability for different device sizes
Solution Approach 2:
The operating section serves multiple functions: it simultaneously controls the extension and retraction of both telescoping clamp members, and also provides the clamping force through the elastic assembly. This multi-functional design allows a single component to perform what previously required two separate manual operations
2Ease of operation
If two telescoping clamp members are extended individually, then each can be positioned independently, but the mobile device easily fails to be clamped or may fall and be damaged, reducing reliability
Solution Approach 1:
By merging the control of both telescoping clamp members into a single driving assembly, the system ensures they extend and retract in unison. This synchronized operation eliminates the risk of one clamp member being positioned incorrectly while the other is properly positioned, significantly improving clamping reliability and preventing device drop
Solution Approach 2:
The elastic assembly provides mechanical feedback that ensures both clamp members are properly engaged. When the driving assembly extends the telescoping members, the elastic assembly stores energy and provides resistance that confirms proper clamping engagement, giving the user tactile feedback that the device is securely held
3Productivity
If a user holds the mobile device with one hand and extends two telescoping clamp members with the other hand, then the device can be positioned, but the operation becomes complex and time-consuming, reducing productivity
Solution Approach 1:
The patent extracts the manual operation requirement from the clamping process by implementing an automatic driving assembly. The driving assembly automatically extends and retracts the telescoping clamp members without requiring manual manipulation, reducing the operation to simply placing the device and allowing the mechanism to self-adjust, thereby dramatically improving productivity
Solution Approach 2:
The driving assembly performs the clamping operation autonomously once the device is placed on the bracket. The elastic assembly automatically provides the force needed to extend and retract the telescoping members, making the system self-servicing and eliminating the need for continuous manual intervention, thus simplifying the overall operation
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 safe and convenient clamping of mobile devices with a single hand, reducing the risk of damage and improving usability compared to traditional two-handed operation.
Implementation Method 1
the elastic assembly generates a pre-force; when the elastic assembly is released, the pre-force drives the driving assembly to rotate reversely

AI summary
An adjustable telescopic bracket for clamping an object includes a main body, a driving assembly, an elastic assembly, and a telescopic member. The driving assembly and the elastic assembly are disposed in an operating space of the main body. The telescopic member has a sliding portion in a sliding groove of the main body. The sliding portion has a resisting portion disposed at an end thereof, and a driving section which is transmittably connected with the driving assembly. The sliding portion is able to be extended, forcing the driving assembly to rotate, whereby the elastic assembly generates a pre-force. When the elastic assembly is released, the pre-force drives the driving assembly to rotate reversely. As a result, the resisting portion is retracted to the main body with the sliding portion on which the resisting portion is disposed, for clamping the object.
