Adjustable Clip Probe Holder for One-Handed Calibration Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holding structures require two hands to secure and adjust the holding force on objects, making it cumbersome to hold objects of different dimensions and weights, especially in environments like calibration baths where single-handed operation is desirable.
Innovation Solution
A holder system with a movable clip attached to a tube, where the clip's aperture size is adjustable using a spring mechanism, allowing single-handed operation and variable holding force adjustment by changing the number of turns of a helical coil spring, enabling secure positioning of measurement probes in calibration instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional holder with a fastener is used to hold objects of different dimensions and weights, then the holding force can be adjusted, but two hands are required for operation (one to secure the holder and another to twist the fastener)
Solution Approach 1:
The patent combines the holder body and the fastening mechanism into a single integrated structure. The biasing element (spring) is built into the holder itself, eliminating the need for a separate fastener that requires two hands to operate. The user can secure the holder with one hand while the spring automatically provides the holding force, achieving single-handed operation.
Solution Approach 2:
The biasing element (spring) automatically provides the holding force without requiring manual adjustment. Once the holder is positioned, the spring self-generates the clamping force to secure the object, eliminating the need for a second hand to twist a fastener and adjust the holding force.
2Adaptability or versatility
If a fixed aperture holder is used, then the structure is simple, but it cannot accommodate objects of different dimensions
Solution Approach 1:
The holder features a movable wall that can be positioned at different locations to create apertures of varying sizes. This dynamic adjustment capability allows the holder to accommodate objects of different dimensions while maintaining a relatively simple overall structure, as the adjustment mechanism is integrated into the holder body rather than being a separate complex system.
3Adaptability or versatility
If a holder designed for specific objects is used, then the holding precision is high, but it cannot hold objects of varying weights and dimensions
Solution Approach 1:
The biasing element (spring) can be selected or adjusted to provide appropriate holding force for objects of varying weights and dimensions. By changing the spring constant or pre-load, the holder maintains reliable and consistent holding force across different object types, ensuring both adaptability and reliability.
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 secure, single-handed operation of holding objects of varying dimensions and weights in calibration instruments, improving efficiency and safety by reducing the need for dual-handed manipulation and ensuring consistent holding force across different objects.
Implementation Method 1
a spring inside the tube, the spring being coupled to the movable clip by a first retainer and being coupled to the cap by a second retainer
Implementation Method 2
The spring may be a helical coil that is coupled to the movable clip by a first retainer and is coupled to the cap by a second retainer

AI summary
A holder secured to a vertical column by a cross support holds an object in a fixed position. The holder includes a tube that can be secured to the cross support. A movable clip at a first end of the tube is configured to hold the object, e.g., a probe held in a calibration bath. The movable clip includes an aperture. When the movable clip is in an extended position, an object can be inserted into the aperture. When the movable clip moves toward a retracted position, the object is held within the aperture. A cap at the second end of the tube is coupled to the movable clip by a spring inside the tube. The movable clip exerts an adjustable holding force on the object by adjusting a number of turns of the spring between the cap and the movable clip. A central holding device may support multiple holders.
