Reagent Container Cover Opener with Dynamic Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cover openers for reagent containers are unreliable due to geometrical or dimensional nonuniformity of the concave portion and tooth-like structure, leading to improper hold and inconsistent cover opening processes.
Innovation Solution
A cover opener mechanism with a carrier and cover retainer that can adjust vertically and rotate, using springs to accommodate nonuniformities, ensuring reliable retention and removal of the cover by engaging protrusions with grooves and rotating the cover for secure opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed snap-in element and fixed carrier configuration are used, then the device structure is simple, but the cover opening process becomes unreliable due to geometrical or dimensional nonuniformity of the concave portion and tooth-like structure
Solution Approach 1:
The patent applies dynamics by making both the snap-in element and carrier movable relative to each other vertically, and the carrier rotatable relative to the centering unit. This dynamic configuration allows the mechanism to adapt to geometrical or dimensional nonuniformity of the concave portion and tooth-like structure on the cover, ensuring reliable engagement and cover opening process despite variations in container geometry.
Solution Approach 2:
The patent changes the positional parameters of the snap-in element and carrier dynamically. The snap-in element can move vertically relative to the centering unit, and the carrier can rotate relative to the centering unit, allowing the mechanism to accommodate variations in the cover's concave portion position and orientation, thereby improving reliability.
2Ease of manufacture
If the snap-in element and carrier are fixed in relative position, then the mechanism is simple to manufacture, but it cannot accommodate geometrical or dimensional nonuniformity leading to improper hold
Solution Approach 1:
The patent introduces dynamic adjustment capabilities where the snap-in element can move vertically relative to the centering unit, and the carrier can rotate relative to the centering unit. This dynamic design allows the mechanism to adapt to geometrical or dimensional nonuniformity in the cover structure, ensuring reliable retention without significantly complicating manufacturing.
3Adaptability or versatility
If a movable carrier with fixed snap-in element is used, then some adjustment capability is provided, but geometrical or dimensional nonuniformity of the concave portion still cannot be fully accommodated
Solution Approach 1:
The patent enhances adaptability by making both the snap-in element and carrier movable. The snap-in element can move vertically relative to the centering unit, and the carrier can rotate relative to the centering unit, providing comprehensive adjustment capability to accommodate geometrical or dimensional nonuniformity of the concave portion and tooth-like structure, ensuring consistent cover opening.
Solution Approach 2:
The patent adds rotational degree of freedom to the carrier relative to the centering unit, and vertical movement capability to the snap-in element relative to the centering unit. This multi-dimensional adjustment capability allows the mechanism to accommodate variations in the cover's concave portion position and orientation, improving cover opening consistency.

AI summary
A cover opener for opening a cover 1a that is rotationally removed from and fixed to a reagent container 1 includes: a rotational drive unit 12 driven by a rotational driving mechanism 5 to rotate about a rotational axis of the cover 1a; a cover retainer 17 provided to be movable in a direction of a rotational axis with respect to the rotational drive unit 12 and to retain the cover 1 by becoming engaged with a concave portion 1b provided on an upper portion of the cover 1a; a carrier 16 provided at an opposed position with respect to the cover 1a and including a plurality of protrusions 16c formed for engagement with a plurality of grooves 1c spaced from each other on an upper outer circumference of the cover 1a, the carrier 16 being driven to rotate as the rotational drive unit 12 rotates, as well as to move in a direction of a rotational axis with respect to the rotational drive unit 12; and springs 19 and 20, one of which is provided between the rotational drive unit 12 and the cover retainer 17, and the other between the rotational drive unit 12 and the carrier 16, the spring 19, 20 biasing the rotational drive unit 12 and the cover retainer 17 or the carrier 16 in relative fashion to move away from each other; the cover 1a being opened in the above configuration. This enables the cover of the reagent container to be reliably opened.
