Clamping Device Angled Pivot Mechanism Wedging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cup holders fail to maintain maximum clamping height and prevent narrow objects from becoming wedged, leading to unstable fixation and potential wedging issues.
Innovation Solution
A clamping device with a pivotally mounted compensating element, oriented at two angled axes, featuring a funnel-shaped recess for rotational freedom, ensures the compensating element pivots laterally and downwards upon object insertion, maintaining maximum clamping height and preventing wedging by providing stable fixation through spring-loading and adjustable bearing configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-axis pivoting compensating element is used, then the device structure is simple, but the clamping height cannot be maintained at maximum and narrow objects may become wedged
Solution Approach 1:
The compensating element is mounted to pivot about two axes oriented at an angle to one another instead of a single axis. This dual-axis configuration enables the element to pivot laterally out of the insertion opening while simultaneously pivoting downwards in the insertion direction, maintaining maximum clamping height and preventing narrow objects from becoming wedged between the compensating element and the receptacle wall.
2Device complexity
If the compensating element pivots only in one direction, then the mechanism is simple, but it cannot adapt to objects of varying sizes and shapes
Solution Approach 1:
By introducing a second pivot axis oriented at an angle to the first axis, the compensating element gains the ability to move in two different directions. This allows the element to first pivot laterally to accommodate objects of different widths, then pivot downwards to maintain optimal clamping height, thereby adapting to various object sizes and shapes while preserving a relatively simple mechanical structure.
Solution Approach 2:
The dual-axis pivoting mechanism allows the compensating element to dynamically adjust its position in response to inserted objects. The element can pivot laterally and downwards in a coordinated manner, providing adaptive clamping that responds to the dimensions and shape of different objects while maintaining stable fixation.
3Device complexity
If the compensating element is mounted with limited rotational freedom, then the bearing structure is simple, but the element cannot achieve optimal clamping position
Solution Approach 1:
The bearing structure is designed to support pivoting about two axes oriented at an angle to one another, providing the compensating element with rotational freedom in two directions. This enables the element to achieve the optimal clamping position by pivoting laterally and downwards, ensuring precise maximum clamping height while maintaining a relatively simple bearing configuration.

AI summary
The device has an insertion opening (25) lying opposite to a base surface, and a pivotally mounted compensating element (20) preloaded in a direction on an article (10) to be retained. The object is extended to the insertion opening, and the compensating element is pivotally mounted about the axles (30, 40) that are oriented at an angle to each other. The compensating element is spring-loaded about the axles, where one of the axles is vertically or horizontally oriented. The compensating element includes a funnel-shaped recess that is formed as a receiver for a bearing pin.
