Modular Cradle Assembly for Stable Stacking of IVD Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in vitro diagnostic devices with varying sizes require a cradle structure that can stably support them when stacked, as their fastening structures and sizes differ.
Innovation Solution
A cradle assembly comprising a first cradle supported by a floor surface and a second cradle that can be selectively coupled to the first cradle, featuring guide ribs, insertion ribs, and fastening hooks to accommodate devices of different sizes, ensuring stable support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed cradle structure is used to support in vitro diagnostic devices, then the structure is simple, but it cannot stably support devices with different sizes when stacked
Solution Approach 1:
The cradle is divided into multiple segments: a first cradle and a second cradle that can be selectively coupled. The second cradle can be attached to different positions (front end or rear end) of the first cradle, creating a segmented structure that adapts to various device sizes while maintaining overall structural simplicity
Solution Approach 2:
The cradle assembly transitions from a static fixed structure to a dynamic configurable structure. The second cradle can be selectively coupled to different positions on the first cradle based on the size requirements of the diagnostic devices, enabling the structure to adapt dynamically to different configurations
2Adaptability or versatility
If in vitro diagnostic devices with different sizes are stacked, then device versatility is improved, but stability is compromised due to different fastening structures
Solution Approach 1:
The cradle assembly serves multiple functions: it can support devices of different sizes, accommodate different stacking configurations, and provide stable fastening through guide ribs and hooks. The universal design allows a single cradle structure to handle various device types and sizes
Solution Approach 2:
Guide ribs and fastening hooks act as intermediary elements between the cradle and the diagnostic devices. These intermediaries facilitate stable coupling by guiding the devices into proper positions and providing secure fastening points, ensuring stability across different device configurations
3Adaptability or versatility
If guide ribs and insertion ribs are added to enable selective coupling, then adaptability improves, but manufacturing complexity increases
Solution Approach 1:
The coupling mechanism is segmented into distinct components: guide ribs on the first cradle, corresponding guide grooves on the second cradle, and insertion ribs that fit into these features. This segmentation allows each component to be manufactured independently using standard processes, reducing overall manufacturing complexity despite the enhanced adaptability
