Biopsy Container Alignment Structures for X-Ray Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biopsy sample containers do not effectively align and secure tissue samples for X-Ray imaging, leading to suboptimal imaging results and sample handling inefficiencies.
Innovation Solution
A biopsy sample container with a hinge-coupled lid, snap fit latches, and alignment structures that securely position and align tissue samples within the container to match the imaging device's field of view, providing audible and tactile feedback for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing biopsy sample containers are used, then sample storage is provided, but sample alignment and secure positioning for X-Ray imaging is not achieved
Solution Approach 1:
The container incorporates self-aligning features including alignment blocks that automatically position the sample within the cavity, and alignment markers on the lid that self-align with corresponding markers on the base during closure. The snap-fit latches automatically engage to secure the sample, eliminating the need for manual alignment operations and ensuring precise positioning without requiring skilled handling.
Solution Approach 2:
The container is pre-configured with alignment blocks, alignment markers, and snap-fit latch mechanisms before use. These features are built into the container structure during manufacturing, so that when the sample is placed in the cavity and the lid is closed, the alignment and securing functions are already prepared and automatically activated, eliminating the need for post-placement alignment operations.
2Reliability
If simple container designs are used, then manufacturing is easier, but secure closure with feedback indication is not provided
Solution Approach 1:
The snap-fit latch mechanism incorporates audible and tactile feedback features. When the lid is properly closed and the snap-fit latches engage, they produce a distinct clicking sound and tactile sensation that immediately informs the operator that the sample is securely positioned. This feedback mechanism provides reliable confirmation of secure closure without requiring complex electronic sensors or indicators.
Solution Approach 2:
The container combines multiple functions into integrated structural elements: the alignment blocks serve both as positioning guides and as part of the closure mechanism, the alignment markers are integrated into the lid structure itself, and the snap-fit latches combine securing function with feedback indication. This merging reduces the need for separate components while achieving multiple objectives.
3Productivity
If manual alignment operations are required, then flexibility is maintained, but time consumption increases
Solution Approach 1:
The container's alignment blocks and alignment markers automatically perform the alignment function as the lid is closed. The alignment blocks guide the sample into the correct position within the cavity, and the markers on the lid self-align with corresponding markers on the base, eliminating the need for manual alignment operations and reducing sample preparation time.
Solution Approach 2:
All alignment features are pre-configured during container manufacturing. The alignment blocks are permanently positioned in the base, and the alignment markers are pre-positioned on the lid. This preliminary configuration ensures that when the sample is placed and the lid is closed, alignment occurs automatically without requiring time-consuming manual adjustment operations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures precise alignment and secure storage of tissue samples, facilitating efficient imaging and easy handling, allowing for multiple sample imaging without the need for container replacement.
Implementation Method 1
The lid is coupled to the wall portion by at least one living hinge
Implementation Method 2
The male and female snap fit latch portions are adapted and configured to engage with and disengage from each other to releasably secure the lid in the closed position

AI summary
A sample container for use in imaging includes a bottom portion and a wall portion extending upwardly from the bottom portion. The lid overlies the cavity when in the closed position, and a plurality of latches are coupled to the lid and extend substantially orthogonally from the lid. A plurality of recesses are coupled to the wall portion, each recess of the plurality of recesses being adapted and configured to receive one of the plurality of latches. A first alignment structure is within the cavity and is adapted and configured to align a sample lengthwise and widthwise within the cavity such that the sample is aligned relative to an imaging system when the sample container is engaged with the imaging system. A second alignment structure is at least partially within the cavity, and is adapted and configured to align the sample height wise within the cavity.
